Lotus introduces Evora 414E Hybrid

Lotus Evora 414E Hybrid engine

NORFOLK : February 25, 2010 - The 80th International Geneva Motor Show sees Lotus Engineering unveil the Lotus Evora 414E Hybrid concept, a high performance technology demonstrator with a plug-in series hybrid drive system and new technologies for enhanced driver involvement.

• 0-60 mph/97 kph in under 4 seconds
• Total hybrid range of over 300 miles/483 kilometres
• Eco mode or Sports mode featuring realistic 7 speed paddle shift with energy recuperation
• HALOsonic Internal and External Electronic Sound Synthesis
• Torque vectoring for improved dynamic stability
• Integrated glass roof and engine cover and interior concept from Lotus Design

The Lotus Evora 414E Hybrid, so-named because this latest environmentally-focused technology demonstrator from Lotus Engineering produces 414 PS (306 kW) of power, promises breathtaking performance from a highly efficient propulsion system. The concept showcases new developments in plug-in, range-extended electric propulsion, new electronic technologies to enhance driver involvement, the adaptability of the Lotus Versatile Vehicle Architecture (VVA) that underpins the Evora 414E Hybrid and a dramatic new roof system and interior concept from Lotus Design. Through all of these aspects it ultimately demonstrates the exceptional ability of Lotus Engineering to integrate and develop advanced technologies for exciting, efficient, high performance niche vehicles.

The range extended electric drive of the Evora 414E Hybrid consists of two electric motors driving each of the rear wheels independently via single speed geartrain, integrated into a common transmission housing, thus enabling torque vectoring for stability control of the vehicle. Electrical power is stored in a lithium polymer battery pack optimised for energy density, efficiency and high power demand, mounted in the centre of the vehicle for stability and safety. Additional range is provided by the Lotus Range Extender engine, an optimised 1.2 litre, three-cylinder engine, designed specifically for series hybrid vehicles. The drivetrain is designed to combine astonishing performance with efficient, low emissions driving.

Driver involvement is enhanced by the incorporation of HALOsonic Internal and External Electronic Sound Synthesis technologies from Lotus and Harman International, which provide sound contouring within the cabin and improve pedestrian safety outside the vehicle. Integrated with the HALOsonic technology, the Evora 414E Hybrid also showcases a brand new technology from Lotus Engineering, a sports mode that simulates a 7 speed, paddle shift transmission that combines exceptional driver involvement for a hybrid sports car and optimised energy recuperation.

The Evora 414E Hybrid has been designed to highlight Lotus’ innovative electric and hybrid vehicle technology without distracting from the pure sportscar character of the Evora. The solution is innovative, instantly recognizable, beautiful and sporty. It demonstrates Lotus DNA.

Dr Robert Hentschel, Director of Lotus Engineering said: “Innovation has always been at the heart of Lotus and is needed now more than ever. The Evora 414E Hybrid is the perfect demonstration of Lotus Engineering’s core competencies: lightweight architectures, efficient performance, electrical and electronics integration and driving dynamics. The technology demonstrator represents an encapsulation of the advanced technologies that Lotus Engineering continues to develop to overcome the current environmental challenges facing the automotive industry and showcases the future direction that the sector is taking and why Lotus Engineering is perfectly placed to lead the technological development in this area.”

The Drivetrain

For the Lotus Evora 414E Hybrid, Lotus Engineering has developed a highly efficient, high performance drivetrain system consisting of twin motors each limited to providing 152 kW (207 PS/204 hp) of power and 400 Nm (295 lbft) of torque to each wheel via independent, single speed, reduction transmissions integrated into a single housing, enabling torque vectoring dynamic control of the vehicle.

The vehicle energy storage system is made up of the latest Lithium Polymer battery chemistry providing 17 kWH energy storage capacity. The battery pack is optimised for energy density, efficiency and high power demand, with over 100 kW discharge capability.

The Lotus Range Extender engine provides 35 kW (48 PS/47 hp) of power at 3,500 rpm via the integrated electrical generator and features an innovative architecture comprising an aluminium monoblock construction, integrating the cylinder block, cylinder head and exhaust manifold in one casting. This results in reduced engine mass, assembly costs, package size and improved emissions and engine durability. The engine uses an optimised two-valve, port-fuel injection combustion system to reduce cost and mass and can be operated on alcohol-based fuels and/or gasoline. The generator converts mechanical energy to electrical energy to replenish the battery pack charge and provides additional vehicle range in a small light weight package. The generator is also used as a motor to start the range extender engine. The low mass of the range extender unit (85 kg) and compact package makes it ideal for the series hybrid drivetrain in the Evora 414E Hybird.

All the operation and management of the range extender engine, the power management of the batteries and motor control are controlled by Lotus’ electronic control units and software systems. Full energy management of all the operating systems is the key to maximising performance and operation while minimising energy consumption and CO2 emissions.

For everyday commuting journeys, up to 35 miles can be travelled using battery power. The battery can be charged overnight using a conventional domestic mains supply through a socket concealed by the rear number plate. This permits the vehicle to operate with zero tailpipe emissions. For longer journeys, exceeding the battery capacity, the highly efficient range extender engine is used as a generator to supply the motor with electrical power and top up the battery.

Lotus has used its own vehicle simulation tools to determine the size, capacity, power and performance of all the components in the drivetrain system to optimise the system operation. Overall this is far more energy efficient, weight efficient and cost effective than fitting the vehicle with a larger and more expensive battery, which for the majority of short journeys is a redundant weight, which increases energy requirements. With regard to the total lifetime CO2 emissions of the vehicle, including the energy required to manufacture and run it, the range extender solution has a lower overall CO2 footprint than a fully electric car of comparable performance and operating range running with a larger battery.

The Package

The Lotus Evora 414E Hybrid structure is the same award-winning, versatile vehicle architecture used on the Lotus Evora. The low volume architecture was designed with the upmost flexibility in mind. The Evora 414E Hybrid is a perfect example of how to integrate a compact packaged drivetrain, with excellent performance and range, while using this underpinning. The complete chassis has remained unchanged from the Evora which maintains the structural integrity and strength performance of the original car.

The structure progresses the Lotus ‘bonded and riveted’ technology with new and unique extrusions and folded panels, whilst providing production build modularity and lower cost repairs. The chassis has been designed for scalability so that it can be extended in width, length and height. The strength and stiffness of the low volume VVA chassis can be modified cost effectively by varying the wall thickness of the extrusions, without altering the exterior dimensions. The ability to lengthen or shorten extrusions with the option to tailor the chassis stiffness vastly increases the number of vehicles that can be developed from this vehicle architecture.

Driving Dynamics

The Lotus Evora 414E Hybrid offers exhilarating, all-round dynamic performance and takes advantage of Lotus developed torque vectoring dynamics. Torque vectoring, which is the capacity to generate different torques at each of the driving wheels, is particularly suited to electric vehicles and significantly reduces the conflict between stability and response.

A key benefit of separate motors to drive each rear wheel individually is that this facilitates a much higher level of vehicle dynamics control. Driving the wheels with different levels of torque can not only generate all the capabilities of a conventional ESP system using energy regeneration as opposed to brake application, but it can also actively drive each wheel forward at different rates, producing a turning moment at the rear of the vehicle in addition to the steering input.

This can be used to enhance low speed manoeuvrability and ease of parking but can also be used to produce a much greater level of straight line high speed stability. Incorporating lateral sensors the system also provides stability control capabilities and levels of steering response normally only associated with heavy and expensive rear steer systems. This can provide automatic correction of both understeer and oversteer characteristics. In addition, the standard method to provide high speed stability of designing the rear wheels to toe-in is not required as the torque vectoring system automatically provides this stability control, with toe-in increasing rolling resistance, lowering fuel economy and increasing tyre wear. Lotus‘ long history of active suspension control provides the core capability to develop this technology and provides extraordinary driving pleasure on the Evora 414E Hybrid.

Driver Interaction

The Evora 414E Hybrid provides less of a psychological step change for people familiar with high performance cars compared to other electric and hybrid sports cars. The car has a simulated paddle shift gear change offering ultra quick gear changes reminiscent of a dual clutch transmission, while actually single speed. This enhances the driver interaction with the vehicle and provides a driving experience similar to current internal combustion engine high performance sports cars. The Evora 414E Hybrid uses a column mounted paddle shift to simulate the gear change and a synthesised engine sound changes frequency with virtual gear selection. The drive torque is also modulated to simulate a physical feeling of a gearshift jolt.

The virtual gearshift simulation, like a conventional gearbox, is used to change the driving characteristics and response of the vehicle. The most significant aspect that this offers the driver is the ability to control the vehicle deceleration by simulating engine braking through a virtual downshift in gears. Unlike true engine braking, the Lotus system does not dissipate the energy of the moving vehicle through internal engine friction but uses the electric motors to regenerate the energy back into the battery. While many electric and hybrid vehicles provide engine braking, this is generally at a fixed rate or preselected rate. In some driving situations this can either be too aggressive, slowing the vehicle unnecessarily, or too light, requiring additional braking application. The Lotus system effectively allows the driver to select the appropriate level of regeneration by simulating stepping down by one, two or even three gears. The simulation of engine braking through both the gear noise change and the retardation of the vehicle is fully intuitive to a driver familiar with a conventional gearbox. The simulated gearchange capability can be selected for greater driving involvement or switched off for more relaxed driving.

The Evora 414E Hybrid uses the Lotus Engineering and Harman International developed HALOsonic suite of noise solutions. The first of which is Electronic Sound Synthesis. This generates engine sounds inside the vehicle through the audio system where it provides an exciting sports sound in line with the brand and nature of the vehicle together with a high level of driver feedback in an intuitive manner. In addition, it also generates sound on the outside of the vehicle through speakers mounted at the front and rear to provide a warning to increase pedestrian safety, which is especially important for electric and hybrid vehicles which can be difficult to hear at slower speeds.

There are four driver selectable engine sounds currently on the vehicle, two of which have been designed to have characteristics of a multi-cylinder conventional V6 and V12 engine. There is also a futuristic sound and a combination of a conventional engine and a futuristic sound, enhancing the brand identity of the vehicle as a step forward in electric vehicle design.

The addition of this Lotus patented simulated gearshift concept not only provides for an exciting and involving driving experience that customers would expect from a Lotus, but also enhances the driver’s control of the vehicle while providing the capability for more efficient operation through a greater use of energy regeneration.

The Design

The distinctive colour scheme and ‘floating’ roof have been carefully designed to accent the cars electric vehicle technology whilst complementing the iconic lines of the Evora.

Copper, a colour often associated with electrical systems, has been chosen for the car’s exterior and interior. A contemporary satin finish paint is complemented by electrical circuit inspired graphics that highlight the car’s key feature lines and the unique glazed roof panel. The newly extended glazed zone integrates seamlessly with the existing forms of the Evora whilst showcasing the key components behind the hybrid and electric vehicle technology.

The signature copper theme is consistently carried throughout the car from the dramatic seat stripes and instrument panel inserts to the copper callipers that nestle behind the carbon grey forged wheels. Inside the cabin a sense of quality and richness has been created by carefully juxtaposing the different tactile qualities intrinsic to leather, Alcantara and metal.

2011 Lotus Elise - The new Lotus Elise probably has the lowest CO2 for its performance for any gasoline high performance sportscar in the w

2011 Lotus Elise

NORFOLK : February 16, 2010 - The Lotus Elise revolutionised the sportscar market 14 years ago when the small lightweight agile 2-seat mid engine sportscar was introduced. By ensuring that the Elise stuck rigidly to Lotus’ core values of performance through light weight, the Elise was able to produce supercar performance with city car economy.

Making its debut at the 80th International Geneva Motorshow, the 2011 model year Lotus Elise introduces a number of changes and improvements to maintain its class leading position.

For the 2011 model year, the Elise range will consist of the following variants:

• Lotus Elise – 136 PS, less than 155 g of CO₂ /km – new 1.6 litre engine *
• Lotus Elise R - 192 PS, 196 g of CO₂ /km - 1.8 litre engine
• Lotus Elise SC – 220 PS, 199 g of CO₂ /km - 1.8 litre supercharged engine

Key changes and improvements to the whole of the 2011 model year Elise range

• New evolution body design incorporating new front clamshell, rear bumper and engine cover
• New all in one integrated headlights including LED day light running lights and LED direction indicators
• Improved aerodynamics with a reduction in Cd by 4%, resulting in better fuel economy
• New cast and forged wheels
• Vehicle warranty increased from 2 years to 3 years and 36, 000 miles

Additional changes for the 2011 model year entry level Lotus Elise

• New high technology 1ZR-FAE 1.6 litre engine with Valvematic and Dual VVT-I technology to optimise the performance and efficiency of the engine

• Combined fuel consumption 6.14 litres / 100 km (46 mpg)*
• New 6 speed close ratio gearbox
• Cruise control available as part of the Touring pack

The body – an evolution

The new 2011 model year Elise range is on sale now and will be in showrooms from April 2010. The body of the new 2011 model year Elise is an evolution of the iconic Elise design, retaining the character and style, while offering a more planted, purposeful stance and a pure, contemporary look that links it to the Evora. As with all Lotus product the design is an exciting blend of dramatic style and functional efficiency

The new Elise body has a fresh sculptured front, including a new bumper, front clam and access panel that combine to give the Elise a wider look with more road presence.

At the rear of the car the new engine has been encased by a distinctive “twin-spine” engine cover whilst lower down a more aggressive diffuser is tightly wrapped by an elegant new bumper design that now includes the rear licence plate.

New headlamp units with distinctively sculptured LED lighting guides (incorporating daytime running lamps and direction indicators) give a contemporary twist to this classic design. Elsewhere, the signature, Lotus “mouth” and familiar sculptured forms have been sensitively refined to give a crisper, more dynamic look. The repositioning of lamp functions has enabled the creation of broad clean surface between the fenders which combines with sleek corner intakes and prominent splitter detail to give a broader more planted stance.

The theme of purity is carried through to the cooling apertures that are efficiently finished with a new lightweight aluminium mesh that gives the car a classically sporting character.

The rear boot is now opened from the cockpit rather than via a separate key operation. The high quality feel of the Elise is continued throughout the car with the Elise graphic incorporated into the new side LED direction indicators, like those on the Evora.

The driving position, from the perfectly positioned pedals and steering wheel, to the comfortable and supportive seats with ProBax** technology means that, like all Lotus cars, the driver becomes part of the car rather than being just a passenger.

With the sleek new body the aerodynamics have improved giving a reduction in the coefficient of drag of 4%.

Finally, a choice of two beautiful, light weight wheel designs are available; an incredibly light forged wheel and a new cast wheel completes the picture for this sensitive update of a Lotus Icon.

Additional changes to the 2011 model year Lotus Elise

The new 2011 model year Elise has a number of additional changes and improvements, with the installation of a new advanced 1.6 litre Valvematic engine meeting EURO 5 regulations. This new engine is 200cc smaller than the outgoing Elise S model and produces similar power (136 PS, 100 kW, 134 hp at 6800 rpm) with maximum torque of 160 Nm, 118 lbft at 4400 rpm, but offers a significant improvement to fuel economy of over 23%, to 6.14 litres / 100km (46 mpg)* and a reduction in CO₂ emission by more than 13%*. This provides the new Lotus Elise with the lowest CO₂ per performance for any gasoline high performance sportscar in the world. This high technology engine is mated to a new 6-speed manual gearbox, providing closer and more performance orientated ratios than the outgoing 5 speed box.

The 1.6 litre engine is controlled via the bespoke Lotus T6 engine management system. Cruise control is available on the Elise for the first time with the controls present on a stalk located to the left of the steering column.

New cast wheels have been designed specifically for the Elise and the new optional forged wheels weigh just 29.26 kg per set, 2.14 kg lighter than a set of lightweight cast versions. Both are available in silver or black colour.

Dany Bahar, Chief Executive of Group Lotus said, “The Lotus Elise revolutionised the sportscar when it was launched 14 years ago and now the Lotus Elise has become greener, giving drivers access to class leading performance with less guilt.”

Donato Coco, Director of Design said, “The Elise is an iconic sportscar and it was important that we did not complicate its design, so we made the car more pure in its look, improved the aerodynamics, and gave it a more contemporary look with high quality detailing.”

Paul Newsome, Director of Lotus Product Engineering said, “We are always looking at ways of keeping the Elise ahead of its peers and for the 2011 model year we have improved efficiency without losing the innate fun that has made the Elise legendary.”

Andreas Prillmann, Chief Commercial Officer for Lotus Cars said, “In its 14 years of production the Elise has accounted for 32% of all the 61 years of Lotus production, illustrating how significant to the brand and well loved it is. The 2011 model year Elise is greener, purer and more desirable, making it even more relevant to today’s marketplace.

The 2011 model year Elise in more detail.

The Elise - the entry model

Engine

The Lotus Elise introduces the new 1598 cm3, 1ZR-FAE engine, provided by Toyota. The key to this engine’s performance and efficiency is the Valvematic system (a variable valve lift mechanism), which is combined with the dual VVT-i (Variable Valve Timing-intelligent). The engine continuously controls intake valve opening/closing timing and the intake valve lift to vary the volume of the intake airflow, giving significant improvements in efficiency and fuel economy. This ensures optimal performance based on the engines operational condition, thus helping the Elise achieve both high fuel efficiency and high performance.

First of all, the maximum power output is achieved at near maximum revs (engine speed) of 6800 rpm and maximum torque (a respectable 160 Nm, 118 lb.ft) is reached at 4400 rpm. This gives a good combination of mid range pull but also encourages the driver to rev the engine to the maximum permitted engine speed of 7000 rpm (transient rev limit). Like all Elise sportscars, there are three shift up lights, on the binnacle cumulatively lighting when the driver is getting closer to the rev limiter and when all three are illuminated, they flash to indicate that the driver is almost on the rev limiter so time to change up a gear!

The height of the engine cover has been raised by 34mm to accommodate the taller 1ZR engine compared to the previous 1ZZ engine from the outgoing model due, in part, to the additional Valvematic technology included on the new engine. This has given Lotus engineers an opportunity to subtly redesign the rear engine cover to match the design theme from the front and rear of the car.

Chassis

The Lotus Elise is built around the revolutionary and award winning extruded and bonded aluminium chassis, with a lightweight steel rear subframe. The chassis weighs 68 kg (150 lbs) and has a stiffness of 9,800 Nm per degree, giving a high level of control of the suspension. At the rear, and also acting as a rear energy absorbing crash structure, a lightweight steel subframe carries the engine and gearbox. At the front, the radiator and key ancillaries are mounted into a high tech composite energy absorbing crash structure that is both lightweight, compact and over three times more energy absorbing than the equivalent steel structure.

Ride and handling

The legendary Lotus ride and handling gives a superb high performance, sporty drive, combined with a compliant ride and progressive on limit handling, it makes the Elise a car that demands to be driven.

The entry level Lotus Elise weighs 876 kg, making it one of the lightest fully homologated sportscars in the world. This low weight translates into efficient performance with minimal environmental impact in terms of emissions and fuel consumption. The efficiency of the Elise structure means that the 136 PS (100 kW, 134 hp) delivers phenomenal performance.

Few cars can match the delicacy and accuracy of the steering, throttle and brakes of the Elise and all of these factors contribute to the excellent driving experience of the Elise.

Safety

The Elise has high performance AP Racing callipers at the front and Brembo callipers at the rear linked to 282 mm vented and cross-drilled cast iron discs to give excellent stopping power.

The Elise comes as standard with a track tuned ABS system that is designed to be unobtrusive under normal driving conditions. This system is designed to be used on track and has a high threshold, only intervening in emergencies.

The ABS system is linked to a lightweight pedal box with steel pedal arms and extruded aluminium pads. This unit also has an electronic (drive-by-wire) throttle for quick, smooth and more linear engine response.

The impressive braking coupled with excellent handling gives good primary safety and the composite front crash structure and rear crash protection offers efficient secondary safety. Driver and passenger airbags and pre-tensioning seatbelt are standard on all Elise models.

Prices will be announced in March 2010.

* - The Lotus Elise is currently undergoing EC Whole Vehicle Type Approval and official fuel consumption and CO₂ emissions figures, plus performance figures are not yet available. The official figures for fuel consumption and CO₂ emissions and performance will be published on Group Lotus plc’s web site as soon as they become available (www.grouplotus.com) or may be obtained from the PR Department, Lotus Cars Limited, Potash Lane, Hethel, Norfolk, NR14 8EZ, UK.

** -- “ProBax™” seats

Introduced for 2006 Model Year Lotus Exige and Elise cars, ProBax™ seats are designed by Lotus and specifically adapted and developed by NuBax. ProBax™ seats help to significantly improve the postural position of the occupant’s spine whilst seated compared to similar seat shells without ProBax technology. This not only results in an improved level of comfort, but also has significant medical benefits - maintaining a natural curvature of the spine, and markedly improving the body’s blood flow. Increased blood flow has been shown to enhance response times, raise alertness levels and reduce the onset of muscle fatigue. Tests on Lotus seats, with the new ProBax™ technology, have shown an improvement in blood flow of up to thirty per cent over the pre-2006 Model Year Lotus seat.

Lotus Exige S Type 72

Lotus Exige S Type 72

NORFOLK, UK : December 23, 2009 - The Lotus Exige S Type 72 celebrates the most successful F1 car of all time, the Lotus Type 72 Formula One car, which achieved 20 Grand Prix victories between 1970 and 1975.


The Lotus Type 72 was driven by such Lotus greats as Jochen Rindt, Emerson Fittipaldi, Ronnie Peterson and Jacky Ickx and won three Formula One Constructors’ Championships (1970, 1972 and 1973) and two Drivers’ World Championships (the first being won by Jochen Rindt in 1970 and the second by Emerson Fittipaldi in 1972).

The colour scheme of the Exige S Type 72 commemorates the famous and easily recognisable black and gold Lotus Type 72 livery and is finished by the same sign writer who painted racing cars for Team Lotus.

Performance through light weight has long been a Lotus philosophy. The 935kg Exige S Type 72 sprints to 60 mph in just 4.5 seconds and to 100 km/h in 4.7 seconds, before reaching a top speed of 145 mph, 233 km/h. The Exige S Type 72 also offers class leading fuel economy and emissions, with fuel economy of 6.5 litres/100 km (43.5 mpg) on the Extra Urban Cycle and CO₂ emissions of 199 g/km.

The Exige S Type 72 is a powerful supercharged mid-engined sportscar that is equally at home on the racetrack or open road. The intercooled engine has VVTL-i technology ensuring impressive performance all the way to the rev limiter at 8500 rpm.

The Sport Pack comes as standard on the Exige S Type 72 which has a bespoke high quality interior, including black micro fibre ProBax sports seats with gold stitching. Each car comes with a special build plate commemorating one of the F1 car’s 20 Grand Prix victories. The exterior of the Exige S Type 72 features unique black and gold light weight wheels and is finished with hand-painted gold Type 72 and Exige S logos, (the Sport Pack also includes a T45 steel main roll hoop, Lotus Traction Control, twin oil coolers and an adjustable front anti-roll bar).

All Lotus cars offer outstanding handling and performance, and the Exige is no exception offering excellent dynamics and great driver involvement. Lotus ride and handling gives an inspiring driving experience and the mid-engined layout of the Lotus Exige S Type 72 offers fantastic balance and agility.

Luke Bennett, Operations Director for Lotus Cars Limited stated, “The Lotus Exige S Type 72 is an evocative sportscar, combining cutting edge handling and performance with the iconic Type 72 colour scheme, one of the most famous racing liveries of all time. The Exige provides an intense driving experience either on road or track and this limited edition is a worthy car to celebrate such a legendary racing car.”

Clive Chapman, Director of Classic Team Lotus said, “The Type 72 was a very significant car for Team Lotus and indeed for the world of F1. It was a revolutionary design that pioneered the use of side mounted radiators to achieve its distinctive ’wedge’ profile, which delivered a significant aerodynamic advantage. Furthermore, by minimising unsprung weight and using a torsion bar, rising rate suspension, tyre performance was excellent. The Lotus Type 72 design was so advanced that it was competitive for an extraordinary six years.”

Lotus Omnivore Engine – 10% Better Fuel Economy than Current Leading Gasoline Engines

Lotus Omnivore Engine Prototype

NORFOLK : December 10, 2009 - Initial phase of Omnivore development achieves 10% improvement in fuel consumption compared to stratified direct injection engines, also with ultra low emissions. The research signals a potential paradigm shift with engine ‘upsizing’ for increased fuel economy.


The detailed research has so far focused on lower speed and load conditions that represent a major proportion of an engine’s operation in a real world environment. At 2000rpm and up to approximately 2.7 bar IMEP (Indicated Mean Effective Pressure), the ISFC (Indicated Specific Fuel Consumption) achieved is approximately 10% better than current spray-guided direct injection, spark ignition engines. Emissions results are an impressive 20 ppm NOx at less than 2.3 bar load and has four-stroke-equivalent hydrocarbons and carbon monoxide emissions.

Simon Wood, Technical Director of Lotus Engineering said: “These impressive results represent an important step-forward in Lotus Engineering’s strategy of developing an array of more efficient multi-fuel combustion systems. Omnivore lays the foundations for a novel and pragmatic vision of a variable compression ratio engine concept suitable for production. A multi-cylinder version is practical for a wide variety of vehicles and offers greatest benefit to C and D class passenger cars which can take advantage of the low cost architecture and significantly improved fuel economy and emissions. We are continuing our discussions with other manufacturers and eagerly anticipate the development of multi-cylinder demonstrations of this revolutionary engine configuration.”

The Omnivore engine concept achieves wide-range HCCI combustion and low CO2 emissions through the application of a simple wide-range variable compression ratio mechanism, itself facilitated by the adoption of the two-stroke operating cycle. Technologies combined in this package are all synergistic and provide a route to the efficient use of alternative fuels, accelerating the displacement of fossil fuels.

Jamie Turner, Chief Engineer of Powertrain Research at Lotus Engineering said: “The automotive industry, including Lotus Engineering, has quite rightly advocated engine downsizing for four-stroke engines. This is as a result of the dominance of the four-stroke cycle in the automotive world and its generation of throttling losses at part-load, where vehicles run most of the time. The two-stroke cycle, conversely, does not suffer from significant throttling losses and in many ways is a more natural fit for automotive use. With the thermodynamic disadvantages of throttling losses removed, the two-stroke engine is free to be sized according to its improved part-load fuel consumption. Downsizing therefore isn’t vital and, due to the improved light-load efficiency and emissions performance we see with Omnivore, this technology approach and ‘upsizing’ could permit a more efficient engine.”

The initial Omnivore programme has been in collaboration with Queen’s University Belfast and Orbital Corporation Limited Australia, with sponsorship from DEFRA/DECC and DOE NI through the Renewables Materials LINK programme. Future work by Lotus Engineering will concentrate on further investigating the operation on gasoline and alternative renewable fuels such as ethanol and methanol, with more in-depth analysis of specific test points.

Lotus Omnivore Comparison Graph

Technical Detail

Omnivore Summary

The Omnivore engine concept features an innovative variable compression ratio system and uses a two-stroke operating cycle with direct fuel injection. It is ideally suited to flex-fuel operation with a higher degree of optimisation than is possible with existing four-stroke engines.

The engine concept features a monoblock construction that blends the cylinder head and block together eliminating the need for a cylinder head gasket, improving durability and reducing weight. In this case, the application of a monoblock is facilitated by the absence of the requirement for poppet valves. A novel charge trapping valve in the exhaust port allows asymmetric timing of exhaust flow and continuous variation of the exhaust opening timing.

The Omnivore engine uses the Orbital FlexDI fuel injection system which produces fine in-cylinder fuel preparation irrespective of fuel type and, together with air pre-mixing, allows efficient two-stroke combustion and low-temperature starting, whilst offering singular opportunity for advanced HCCI control.

The variable compression ratio is achieved by the use of a puck at the top of the combustion chamber. This simple, yet effective system moves up and down effecting the change in geometric compression depending on the load demands on the engine.

Engine Concept Features

Monoblock

The monoblock incorporates the cylinder head, the cylinder barrel and the inlet ports, together with mounts for the variable compression ratio system and the charge trapping valve housing. It also contains the non-moving location of one of the two possible injector mounting positions provided for research purposes. The other injector position is in the variable compression ratio puck. The monoblock is mounted on the upper crankcase, which is a common component with all of Lotus’ single-cylinder research engines. The engine carries a full primary and secondary balancer system. The monoblock is water-cooled by an electric water pump.

Computational fluid dynamics is used extensively to ensure effective cooling of the monoblock, a feature assisted by the removal of the cylinder head gasket, inherent in such architecture. The chief advantage of a monoblock construction in any engine, aside from the bill of materials and assembly benefits, is the reduction of bore distortion afforded by the removal of cylinder head bolts. This is especially important in piston-ported 2-stroke engines.

Variable Compression Ratio Mechanism

The primary component of the variable compression ratio mechanism is what is termed the ‘puck’, or a moveable junk piston in the cylinder head. In the case of the research engine, this puck is driven in and out by a double-eccentric mechanism itself comprising proprietary parts. The puck itself does not move at engine speed. In addition to the spark plug, the puck carries one of two possible injector positions. It is water-cooled and carries simple piston (or ‘junk’) rings for primary sealing, and an ‘O’-ring towards the top for final sealing.

The variable compression ratio system is controlled by an electric motor and worm drive arrangement at the front of the engine. Because there are no poppet valves in the engine, it is clear that the puck could be of a large diameter and since there is no need for valve cut-outs in the piston crown, the minimum volume of the combustion chamber can be much smaller than has been the case in variable compression ratio engines shown to date. When the puck is in its innermost position, its surface is essentially coincident with that of the combustion chamber squish band and this yields the highest compression ratio of 40:1.

The combustion chamber geometry necessarily alters as the puck is moved to vary the compression ratio. The chamber geometry in Omnivore was therefore chosen on the basis of 2-stroke experience in spark ignition operation. Consequently, the puck is positioned in the cylinder head in such a way that the non-moving squish band directs cooling flow towards the spark plug. The puck is water-cooled from the main engine cooling circuit.

Charge Trapping Valve

The charge trapping valve is caused to oscillate by a short articulated connecting link from an engine-speed eccentric shaft itself rotated by a belt drive from the crankshaft. A simple charge trapping valve mechanism provides for asymmetric exhaust timing and hence a modification of the original piston-ported two-stroke operating cycle. Fitting an articulated link between the eccentric shaft and the trapping valve actuating arm affords the opportunity independently to vary the opening and/or closing point. In this ‘variable’ form, at light load, the charge trapping valve can be made to control exhaust port opening, to maximize expansion in the cylinder, and the blowdown period can be optimised. The position of the control arm is controlled by the engine management system. All charge trapping valve components and their configuration have been analysed kinematically, and since they operate with modified simple harmonic motion, they do not suffer from jerk stresses.

Other Components

The cranktrain of the engine comprises an 86 mm stroke crankshaft, a trunk piston of 86 mm bore and a connecting rod with 195.5 mm between centres. The piston carries four piston rings: two pegged half-keystone compression rings which traverse the ports in the upper section, and a Napier scraper ring and U-Flex oil control ring in separate grooves in the lower portion. These are not pegged since they do not have to traverse the ports. In this manner, the working chamber is completely sealed from the crankcase and hence wet-sump lubrication can be employed.

Since this is a research engine, it is cooled by an electric water pump with a separate electrically-driven oil pump used for lubrication. Scavenge air is provided externally. For convenience, air for the Orbital air-assist DI system is provided from the factory air supply regulated to 6.5 bar maximum air delivery pressure. Note that in any multi-cylinder application it is envisaged that all these subsystems would be incorporated into the engine in the normal manner.

The Lotus force has a dark side: Revealed - the exclusive ‘Exige Scura’

Lotus Exige SCURA

NORFOLK : October 19, 2009 - Lotus Cars unveils its latest special edition - the Exige Scura, so called due to its dramatic matt black and carbon fibre theme, at the Tokyo International Motorshow on 21st of October 2009.

Translated as ‘dark’ from Italian, the name ‘Scura’ reflects the stealth character of this already fierce looking Lotus and its stunning soft-feel matt black paint finish. Limited to just 35 cars globally, this Exige evokes a desire to ‘indulge your dark side’. This is a serious looking car and enhancements to performance and a reduction in weight from the production level Exige S means that the Exige Scura demands to be driven by a serious driver.

Contrasting high gloss ‘Phantom Black’ triple stripes run the length of the car and a carbon fibre front splitter, oil cooler inlet vanes, side airscoops and rear spoiler enhance the stunning distinction between the different textures and exaggerate the tactile quality of the velvety touch to the matt black paint finish.

Luke Bennett, Director of Lotus Cars said, “The Exige Scura is a stunning vehicle which offers an adrenaline fuelled experience and is a real head-turner! Our Exige customers choose Lotus because we deliver thrilling performance and dynamic design and this special edition fits the bill on both counts.”

Continuing the dark ‘Scura’ appearance into the interior, carbon fibre is used extensively to compliment the exterior theme and reduce weight. The seats and centre console are crafted from carbon fibre and the handbrake and gear knob have a special anodized treatment which leaves the metal with an anthracite colour finish. All carbon fibre components have been beautifully finished in high-gloss clear lacquer allowing the weave to remain exposed which gives the cabin a raw and racy ambiance.

Whilst there is no doubt that this is a visually stunning car, the Exige Scura is not just about its looks – it begs to be taken on track, and its racing character encompasses poise, power and technology to make it a serious contender. Equipped with the most powerful engine in the Exige range and generating 260PS, the Exige Scura achieves a top speed of around 245 km/h and reaches 0-100 kmh in just 4.1 seconds.

Other equipment fitted as standard to boost the Exige Scura’s track credentials include:

• Launch control to ensure optimum performance from a standing start
  
• Variable slip traction control, enabling the driver to tune the car to track surface conditions and their own driving style
  
• Ohlins 2-way adjustable dampers for personalised ride and handling characteristics

Roger Becker, Vehicle Engineering Director, highlighted the performance of the Exige Scura, “There are very few cars in the world that turn in the performance of the Exige Scura without the penalty of very high fuel consumption and emissions. As with all Lotus sportscars we offer the best of both worlds – a zero to 100 km/h time of just over 4 seconds and a CO₂ figure of 199 g/km; all this is down to light weight and a strict adherence to Lotus’ core brand values.”

Considering the performance on offer, the Exige Scura boasts impressive all round fuel economy with an Official European Combined Cycle figure of 8.5 litres/100 km and 6.5 litres/100 km on the Official European Extra Urban Cycle and emissions of 199 g/km of CO₂.

Orders for the ‘Lotus Exige Scura’ will be accepted from 21 October 2009 in Europe, South Korea, Australia, South Africa, Thailand, Taiwan, Hong Kong, Singapore, New Zealand, Indonesia and Malaysia. This special edition will be available on the same basis in Japan known as the ‘Lotus Exige Stealth’.

The Exige Scura in more detail

Performance and enhancements;

• 0-100 kmh in 4.1 seconds and 199 g/km CO₂
  
• Lotus Launch Control and Lotus Traction Control as standard

The Lotus Exige Scura uses the 1.8 litre supercharged and intercooled 260 PS engine from the range topping Exige Cup 260, including the lightweight flywheel and lightweight supercharger pipework. Coupled with Ohlins 2 way adjustable dampers and Eibach Springs with variable height spring platforms, unique matt black lightweight forged wheels and super sticky Yokohama A048 LTS tyres, ride and handling is as expected for a Lotus!

Lightweight carbon fibre components, including sports seats, interior centre console, front splitter, oil cooler inlet vanes, side airscoops and rear spoiler help to keep the weight to 10kg less than the Lotus Exige S (at just 925 kg).

Lotus Launch Control and Lotus Traction Control – additions recommended for track driving

Lotus Launch Control and Lotus Traction Control were originally developed for the Lotus Exige GT3 racing programme.

The launch control allows the driver to determine the number of revs they wish to use during a standing start. Having programmed that limit, the driver then holds the throttle pedal down fully and sidesteps the clutch pedal for a very quick departure from the line. The clutch damper cushions the severity of the clutch to transmission engagement to minimise the stresses to the drivetrain. The launch control allows wheel-spin until 10 km/h (6 mph) to further reduce drivetrain stress, after which the traction control assumes its duties at the defined level set by the driver.

As with launch control, the amount of traction control required can be dialled in from the driver’s seat and altered on the move to suit the characteristics of particular corners. The amount of traction control can be varied in over 30 increments from an optimum 7 percent tyre slip to completely inactive. The message display in the new instrument pack displays what degree of traction control is being currently utilised.

Suspension

To suit individual driving styles and road conditions, drivers will now be able to tune the Exige suspension with the Ohlins two-way adjustable dampers (which have 60 compression and 22 rebound settings) and ride height adjustment to reduce the ride height from 130 mm to 120 mm.

Performance, Economy and Emissions

The Lotus Exige Scura is capable of incredible track performance which and at the heart of its success is the aerodynamic package, which produces 42 kg of downforce at 160 km/h (100 mph) increasing grip and stability at higher speeds. This downforce, coupled with a top speed of around 245 km/h (152 mph) and a zero to 160 km/h (100 mph) in circa 9.9 seconds, 0 to 100 km/h in circa 4.1 seconds (0 to 60 mph in around 4 seconds), means that the Exige Stealth is not only stunning to look at but a phenomenal performer too. Combined cycle fuel consumption is 8.5 l/100km and the CO₂ emissions 199 g/km.

Engine

The supercharged and intercooled engine in the Exige Scura has a maximum power output of 260 PS (257 hp) at 8000 rpm and a torque figure of 236 Nm (174 lbft) at 6000 rpm. This significant amount of extra power and torque over the production level Exige S together with the VVTL-i variable cam system ensures that there is a smooth and linear delivery of power from low engine speeds all the way to the maximum 8000 rpm (8500 rpm transient for 2 seconds). The supercharger (with a sealed-for-life internal mechanism meaning that it does not require the use of the engine’s oil) is run from the crankshaft and has an integral bypass valve for part load operation. Charge air (air under pressure from the supercharger) is cooled through an air-to-air intercooler (the air enters via the enhanced roof scoop) before being fed into the engine itself. All charge air ducting has been kept as short as possible with large diameter pipes to minimise restriction and maximise throttle response and efficiency. Four high capacity injectors and an uprated fuel pump add additional fuel under hard acceleration or continuous high speed driving – only on the track, of course!

A lightweight flywheel is fitted (giving even greater flexibility and response to the gear change), a sports-type clutch plate and heavy duty clutch cover transfer the engine power and torque to the lightweight C64 six-speed gearbox (with an aluminium casing) – with the same perfectly spaced ratios as the Exige S. An Accusump (engine oil accumulator unit) is included in the whole package as an oil reservoir back-up for extreme track use ensuring that, under those conditions, the engine oil pressure remains constant.
