Geneva Preview: Lotus Exige 270E Tri-Fuel

As its name suggests, the Lotus Exige 270E Tri-Fuel is equipped with a 1.8-liter supercharged engine that can run any mixture of gasoline, bioethanol and methanol. Using a development of the supercharger and intercooler package from the Exige S, the Exige 270E Tri-fuel has peak power of 270 hp at 8000 rpm, 184 lb/ft (260 Nm) of torque at 5500 rpm, up by 51 hp or 19% and 25 lb/ft 45 Nm or 14% over the standard gasoline Exige S.

That makes the Exige 270E Tri-fuel the most powerful road version of the Exige range. According to the British carmaker, the Exige 270E can go from standstill to 60 mph (96 km/h) in just 3.9 sec and on to a top speed of 158 mph or 255 km/h. –More details after the jump

PRESS RELEASE:

Lotus Researches Cars Running On CO2 Exige 270E Tri-fuel is the next stage of Lotus Engineering’s long-term sustainable, synthetic alcohol research

Lotus Engineering, the world renowned automotive consultancy division of Lotus, unveils its latest development towards carbon neutral road transport at the 78th Geneva International Motor Show. The Lotus Exige 270E Tri-fuel is the most powerful road version yet of the Exige (0-60 mph / 96 kph in 3.88 seconds, a top speed of 158 mph (255 km/h), 270 hp (201 kW / 273 PS at 8000 rpm) and it runs on any mixture of gasoline, bioethanol and methanol. Emerging technologies will allow alcohol fuels such as methanol, already a proven internal combustion fuel, to be made synthetically from CO2 extracted from the atmosphere.

An alcohol-based fuel derived renewably from atmospheric CO2 would allow society to transfer relatively easily to sustainable, carbon-neutral internal combustion. Lotus Engineering is researching the use of sustainable synthetic alcohols as potential future fuels, with technology available from Lotus for introduction in four to five years. However, the supply infrastructure investment from governments and fuel companies could take 15 to 20 years.

The Exige 270E Tri-fuel is part of Lotus’ research to understand the complex combustion process involved in running on mixtures of alcohol fuels and gasoline, which will be important for a successful transition from today’s fuels to the sustainable, synthetic fuels of the future.

This research is just one aspect of Lotus Engineering’s ground-breaking work on environmentally-friendly vehicles. It is involved with a number of electric vehicle projects, has successfully integrated hybrid technologies into vehicles such as its EVE demonstrator, and recently announced results on a collaboration with Continental Division Powertrain on the Low CO2 downsized three-cylinder engine. The research into sustainable alcohols is progressing at Lotus’ Hethel headquarters in Norfolk, UK and involves input from the Royal Society of Chemistry’s Alternative Fuel Symposium Series, the Low Carbon Vehicles Innovation Platform, developed by the Technology Strategy Board and direct discussions with the University of Sheffield.

Methanol (CH3OH) can be produced synthetically from CO2 and hydrogen. Ultimately, emerging processes to recover atmospheric CO2 will provide the required carbon that can entirely balance the CO2 emissions at the tailpipe that result from the internal combustion of synthetic methanol. The result is that a car running on synthetic methanol, such as the Exige 270E Tri-fuel would be environmentally neutral.

As well as being green, the great benefit of synthetic methanol is that it would use similar engines and fuel systems to those in current cars; and synthetic methanol can be stored, transported and retailed in much the same way as today’s liquid fuels such as gasoline and diesel.

Synthetic methanol also possesses properties better suited to internal combustion than today’s liquid fuels, giving improved performance and thermal efficiencies. And it is ideal for pressure-charging (turbocharging and supercharging) already being introduced by manufacturers to downsize engines in a bid to improve fuel consumption.

Lotus Engineering’s Lotus Exige 270E Tri-fuel technology demonstrator illustrates how easy it is for synthetic methanol to be embraced over time as a future fuel for road transport. The Exige 270E Tri-fuel, with its supercharged 2ZZ-GE VVTL-i engine, could be the forefather of a new generation of conventionally driven cars that have the potential to be environmentally-neutral.

Mike Kimberley, Chief Executive Officer of Group Lotus plc, explains: “Lotus is a world-class leader in research into a variety of alternative fuels; each has its merits and challenges and some options could be more easily implemented than others. But while motorists want to be green, we do not want to change the culture of total freedom for the owners, who will have an extreme reluctance to spend more at the pump, or to sacrifice the performance of their cars.

Mike Kimberley continues, “At present, the motor industry is seeking a route to reduce CO2 emissions just at the tailpipe; this focus is far too narrow. A sustainable alcohol such as synthetic methanol has the potential to reduce the overall CO2 footprint of internal combustion vehicles towards zero. Produced through CO2 recovered from the atmosphere and given a tax incentive, it immediately becomes a green, cheap and more desirable fuel. For those compelling reasons motorists, legislators and car manufacturers must switch to a sustainable alcohol like synthetic methanol.”

Geraint Castleton-White, Head of Powertrain at Lotus Engineering explains: “For car companies and the motorist, the use of sustainable alcohols like synthetic methanol requires relatively few changes to the vehicle. It can also use the current fuel distribution infrastructure, which is a huge advantage for suppliers.

Geraint Castleton-White continues, “We believe that, technically, there are a small number of significant but by no means insurmountable hurdles to the adoption of synthetic methanol as the staple future fuel for internal combustion. We are some way into a number of extensive research projects but of course, we understand that further research needs to be undertaken to fully overcome potential challenges that may arise.”

David Bott, Director of Innovation Platforms within the Technology Strategy Board in the UK says: “The approach taken by Lotus Engineering is a good balance between the desire for the lowest carbon emissions and the practicality of car evolution. The drive for low carbon transport is a real imperative and its progress will require short, medium and long term solutions.”

Tony Ryan, ICI Professor of Physical Chemistry at the Department of Chemistry at The University of Sheffield says: “There is a great opportunity to develop methanol as a transport fuel in a mixed energy economy that embraces a wide range of primary energy sources, including nuclear, solar, and other renewable power sources. Combining atmospheric CO2 with hydrogen to form methanol provides a pathway to personal transport with low carbon emissions that uses the existing liquid-fuel infrastructure and Lotus Engineering offers world leadership in the development of engines to use these fuels of the future.”

Synthetic methanol – a green fuel?

Synthetic methanol’s green credentials arise from its potential to be completely CO2 neutral. The most likely future mass-production of the fuel is by using electrochemical techniques to combine oxygen, hydrogen and carbon:

Carbon could be sourced from carbon dioxide recovered from the atmosphere using either large scale extraction facilities or biomass.

Oxygen would be taken from the atmosphere already contained in the CO2 molecule.

Hydrogen would be acquired through the electrolysis of water; challenges remain in the electrical power required; in a green future, this could be supplied from renewable sources, an issue already being addressed by supporters of hydrogen as a fuel.

Synthetic methanol can also be supplemented by production from biomass sources where properly sustainable.

Methanol can be produced easily from a wide variety of feedstocks.

Please see Synthetic Methanol Cycle Diagrams attached

Synthetic methanol – How to make it?

Techniques for the production of synthetic methanol through the extraction of atmospheric CO2 are well developed and understood but are not being employed on an industrial scale. An early solution would be the co-location of a nuclear or hydroelectric powerplant with a conventional power station – the hydrogen generated by hydrolysis of water would be combined with CO2 from either fossil or biomass sources to make liquid methanol. In the future, large volumes of CO2 could be extracted directly from the atmosphere.

Synthetic methanol – easy to adopt?

As well as being green, another crucial advantage of synthetic methanol is that it can be introduced relatively simply. As the Exige 270E Tri-fuel demonstrates, only small changes to engines are required, such as:

Sensors to detect alcohol content

Modified software for engine management control driving alcohol/gasoline, flex fuel and fuel systems operations.

Fuel lines compatible with alcohol fuels

Higher flow rate fuel pump and injectors

Fuel tank material, compatible with alcohol In addition, as a liquid, which is miscible with gasoline, synthetic methanol can be transported; stored and sold to motorists exactly as today’s liquid fuels are, with only minor modifications.

Synthetic methanol – a performance fuel?

Synthetic methanol is better suited to spark-ignition combustion than today’s liquid fuels, delivering better performance and thermal efficiencies, due to its higher octane rating giving it better resistance to ‘knock’. As a result, it is a fuel that will benefit the motorists in terms of driving experience. For example, the Exige 270E Tri-fuel is quicker to 60mph from standstill and has a higher top speed when using 100% synthetic methanol fuel than with conventional gasoline. Synthetic methanol is also ideally suited to pressure-charging, a trend already well underway as car makers look to downsize engines to reduce fuel consumption.

Synthetic methanol -the way forward

Lotus Engineering regards sustainable alcohols as the third step in a process towards carbon neutral driving. The current E85 (85% ethanol and 15% gasoline) based movement represents the first stage in building momentum towards sustainable fuels. The valuable learning from the current bioethanol vehicles on the market means that synthetic methanol would easily be managed technically and within the existing transport, storage and distribution infrastructure. The steps towards a synthetic methanol economy for transportation fuels could be as follows:

1^st Generation: there is a handful of current bioethanol models on sale around the world. These cars run on E85 bioethanol, which is produced from valuable arable crops (food). This is unsustainable in the short and medium term as global demand for fuel will outstrip the supply available from farmland to the detriment of food production, but is a necessary step in the evolution of the market. 2^nd Generation: the next generation bioethanol fuels will be based on biomass waste, for example crop stubble, waste vegetable-based oils and any biodegradable waste matter. This is thought also to be unsustainable in the medium to long term as the required volume of biomass increases beyond that which can be supplied. 3^rd Generation: sustainable alcohols such as synthetic methanol can be introduced due to its miscibility with ethanol and gasoline. This fuel can be produced from entirely sustainable, readily available inputs, with an environmentally neutral overall impact. 4^th Generation: Direct Methanol Fuel Cells: over the longer term, sustainable alcohols in internal combustion will facilitate the soft introduction of direct methanol fuel cells as a long term sustainable future fuel. This will only be possible with pure methanol pumps on the forecourt which internal combustion engines can bring forward due to their ability to consume a mixture of fuels.

Lotus Engineering strongly believes governments, fuel suppliers and car manufacturers have a key role to play in the adoption of sustainable alcohols as a future green fuel.

If car manufacturers were incentivised to produce next generation models for introduction over the next 5 to 10 years as flex-fuel vehicles capable of running on any mix of gasoline and bioethanol, there would be no need for an unfeasible instant global changeover. Late software changes can permit the introduction of methanol and fortunately, E85 bioethanol and subsequently synthetic methanol can be introduced gradually to the marketplace, due to their miscibility.

Should fuel suppliers increase the industrial-scale production of synthetic methanol, it could be introduced to forecourts across the globe within 15-20 years and eventually become a global standard.

The Lotus Exige 270E Tri-fuel

The Lotus philosophy is all about performance through light weight. The Exige 270E Tri-fuel is built to the lightest specification possible without resorting to expensive and rare materials. The performance improvements of using synthetic alcohol have been made through increasing the power of the engine without increasing its weight and therefore the overall weight of the car.

The Engine

The heart of the Exige 270E Tri-fuel is a Roots-type supercharger (with a sealed-for-life internal mechanism meaning that it does not require the use of the engine’s oil) and air to air intercooler attached to the tried and tested 4-cylinder, 1.8 litre 2ZZ-GE VVTL-i engine. Using a development of the supercharger and intercooler package from the Exige S, the Exige 270E Tri-fuel has peak power of 270 hp (201 kW / 273 PS) at 8000 rpm, 184 lbft (260 Nm) of torque at 5500 rpm, up by 51 hp (38 kW, 52 PS) or 19% and 25 lbft 45 Nm or 14% over the standard gasoline Exige S. Maximum engine speed is 8000 rpm (8500 rpm transient for up to 2 seconds).

The low carbon number alcohol fuels methanol and ethanol give more power when burned in the engine than conventional gasoline (petrol) fuel. The performance benefits come largely from the high heats of vaporization of methanol and ethanol, which give strong charge-cooling effects, and the increased octane ratings. There are other secondary thermodynamic effects. Methanol's higher heat of vaporization leads to a slightly higher performance relative to ethanol. All charge air ducting has been kept as short as possible with large diameter pipes making sure that the bends in these ducts are not too tight, to the benefit of throttle response and efficiency. The Roots-type Eaton M62 supercharger is turned by the crankshaft, and has an integral bypass valve for part load operation.

The 2ZZ VVTL-i engine has two cam profiles – a high speed cam and a low speed cam. The seamless switch point between these two cams is completely variable depending upon driving conditions and engine load. This gives the Lotus Exige 270E Tri-fuel a smooth and linear surge of power from idle speeds all the way to the maximum 8500rpm. An electronic drive-by-wire throttle ensures the quickest engine response possible whilst keeping the emissions as clean and as low as possible, to meet relevant legislative demands. Six fuel injectors have been fitted to increase fuel flow to the engine at normal and higher engine speeds and loads.

2008 Lotus Sport Exige Cup 260

The most radical version of the Lotus Exige, the track-ready Sport Exige Cup has been revised for the MY2008 with a series of mechanical updates the most important being the new engine management system that boosts maximum power output to 257 hp (260 PS), up by nearly 5 hp (5 PS) over the MY2007 Sport Exige Cup. According to the British firm, the 2008 model achieves a top speed of 247 kmh (147 mph) and a 0 to 160 kmh (100 mph) time of 9.9 sec and 0 to 100 kmh of 4.1 sec (0 to 60 mph in 4 sec).

Additional improvements on the 2008 Model year include the new graphics on the instrument panel, the variable traction and launch control and the new alarm/immobilizer system. –Details after the jump

Press Release

Lotus Sport, the motor sport division of Lotus Cars Ltd, has unveiled the MY2008 Lotus Sport Exige Cup 260.

20th February 2008

Lotus Sport, the motor sport division of Lotus Cars Ltd, has unveiled the MY2008 Lotus Sport Exige Cup 260. A direct development of the 2007 Exige Cup Car, this year’s car has a revised engine management system to take the maximum power output to 257 hp (260 PS), up by nearly 5 hp (5 PS) over last year. Bespoke performance enhancements created to offer a car with even greater levels of handling and acceleration capable of taming Europe’s most challenging race circuits.

The Exige Cup 260, once again represents Lotus’ most radical version of the Exige, with the track environment being its home and for 2008, the Lotus Sport Exige Cup 260 has full European homologation for road use (a must have for some competitive environments where a road legal car has to be entered).

There are further product changes: all Lotus Sport Exige Cup 260 cars now have a number of the 2008 Model year improvements from the road versions of the Elise and Exige, namely:

--Instrument pack with new graphic design and expanded functionality
--New alarm/immobiliser + single integrated function key
--Variable Lotus Traction Control
--Variable Lotus Launch Control

In traditional Lotus style, weight saving is paramount. Weighing in at just 928 kg, the power to weight ratio is an impressive 271 hp / tonne (273 PS / tonne). Such a fantastic power to weight ratio alone of course does not make a superlative track car, so the Exige Cup 260 has a formidable list of standard equipment that includes Lotus specific LTS compound Yokohama A048R tyres, 4-piston AP Racing front brake calipers, adjustable dampers and anti-roll bar, the latest FIA 6-point roll cage and sports driver and passenger seats. The car can also be ordered as a Track version for track use only. The Track Version comes pre-fitted with an FIA approved 6-point roll cage, and 4-point harnesses. In addition, a wide range of motorsport specific options are also available with this version.

• 70 litre fuel cell (FIA approved)
• Yokohama A005 racing slick tyres with Hi-Power silver 5-spoke ultra lightweight forged alloy wheels
• C64 6-speed gearbox with dog engagement and revised ratios
• 1.5-way adjustable plate-type limited slip differential
• Race specification battery with battery tray
• De-cat pipe
• Level 2 stainless steel sports exhaust - 104.0 dB(A)
• Black race seat - driver only (FIA approved)
• Black 6-point harnesses - driver only (FIA approved)

The Lotus Sport Exige Cup 260 is one of the quickest cars around a circuit. Key to this incredible performance is the aerodynamic package, which produces over 40 kg of downforce at 160 kmh increasing grip and stability at higher speeds. With a top speed of 247 kmh (147 mph) and a zero to 160 kmh (100 mph) in circa 9.9 seconds, 0 to 100 kmh in circa 4.1 seconds (0 to 60 mph in circa 4 seconds), the MY2008 Exige Cup 260 is the perfect partner for the serious racer. Combined Fuel Consumption is 9.1 l/100km and the CO2 emissions 216 g/km.

The Exige Cup 260 is available now for sale in mainland Europe at €56,034, exclusive of local taxes and on the road charges. You will find the individual retail prices for some major European markets in a separate list at the end of this release.

Mike J Kimberley, Chief Executive Officer Group Lotus plc said: "In keeping with our racing and high performance sports car heritage, we are very pleased to launch this exceptionally exciting, phenomenal-handling Lotus Sport Exige Cup 260. This is yet another example of how Lotus Cars and high-tech engineering with Lotus Sport, can transform an already brilliant road car into an exceptionally high performance product for the track.”

Further details about the Lotus Sport Exige Cup 260:
Engine

The supercharged and intercooled engine in the Exige Cup 260 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 now available together with the VVTL-i variable cam system ensures that there is a smooth and linear surge of power from low engine speeds all the way to the maximum 8000 rpm (8500 rpm transient for 2 seconds). The Roots-type Eaton M62 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.

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. A Torsen type limited slip differential is fitted as standard, with a plate type limited slip differential available as an option.

Keen to pass on lessons learned on the track with the Exige GT3 racing programme, Lotus Sport has contributed another important technology – launch control combined with variable traction control. This combo has already made its production debut with the track-oriented Lotus 2-Eleven.

From the driver’s seat the launch control allows you to determine the number of revs you wish to use during a standing start. Having programmed that limit, you then hold your foot down hard on the throttle and sidestep the clutch at departure from the line time. The clutch damper cushions the severity of the clutch / transmission engagement to minimise the stresses to the drivetrain (noting that abusive/ continuous standing start applications will destroy the drivetrain components). The launch control also keeps wheelspin at bay until 6 mph, after which the traction control assumes its duties.

As with launch control, you can control the amount of traction control you require from the driver’s seats, altering it 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 off. The message display in the new instrument pack displays what degree of traction control you have currently dialled in.

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.

More than just new dials

The new instrument pack fitted to the whole of the MY2008 Exige and Elise range is also carried over to the Sport Exige Cup 260. It is more than just a fresh pair of stylishly back-lit dials. It also features a high-definition LCD message panel that can display a scrolling text message with vehicle systems information.

The new instrument pack always displays the fuel gauge, engine temperature and odometer, however you can select to display the time, trip distance or a digital read-out of your speed in the opposite calibration to that of your speedometer dial – if your dial is in mph, the readout is in km/h and vice-versa.

Warning symbols are ‘secret until lit’, keeping the instrumentation free from visual clutter and distraction until absolutely necessary. New gearchange ‘shift’ lights similarly remain hidden until required. There are three shift up lights, cumulatively lighting when the driver is getting closer to the rev limiter and when all three are illuminated, they flash to indicate that you’re almost on the rev limiter so time to change up a gear!

A “key” issue

In response to forthcoming legislation, the Exige Cup 260 has a new “Thatcham approved” alarm/immobiliser system. This, in turn, has enabled the new Lotus design of key that incorporates the controls for the alarm/immobiliser and central locking functions. This upmarket key fob features three buttons, the one which locks the doors and sets the alarm/immobiliser is stylishly crowned with the famous Lotus roundel. The second button unlocks the doors and de-actives the alarm/immobiliser, and the final button is a panic button.

Roof Scoop

The Lotus Sport Exige Cup 260 retains the full length roof scoop from the outgoing Sport Exige Cup 255, which improves the intake ambient air flow rate, so allowing the Exige Cup 260 to gain a higher charge density in the cylinders.

Wheels and Tyres

16-spoke cast wheels are shod with Lotus specific LTS compound Yokohama A048R tyres to maximise grip and achieve the ride and handling targets set by Lotus.

Brakes

The brake system includes large diameter 308 mm 2-piece aluminium belled cast iron cross-drilled and ventilated front discs and 282 mm cross-drilled and ventilated discs at the rear, upgraded Pagid RS14 sports brake pads set into the brake calipers (AP Racing two piece radially mounted, 4 piston at the front and Brembo sliding at the rear), high grade silicone brake fluid and stainless steel braided brake hoses - all linked to the proven Lotus track tuned servo-assisted four-channel ABS system that enhances braking performance and minimizes stopping distance without taking over from the skill of the driver.

Suspension

Adjustable dampers and a stiffened and adjustable front anti-roll bar allows customers to tailor the handling characteristics of the car to their own requirements.
As the Lotus Sport Exige Cup 260 cars are equipped for track use, a double shear track control arm brace is provided to cope with the expected kerb abuse during racing or hard track day driving.

Safety Equipment

Lotus Sport Exige Cup 260 cars have the safety equipment expected of a race car, with sports seats, 3-point “Webb Lock” harnesses (4-point driver and passenger seat belt harnesses are provided for track use only). The 6-point roll cage is FIA approved and is provided with the vehicle as a no-cost option for dealer fit after delivery. Completing the additional safety equipment is An electronic ignition kill switch with cockpit and external activation and a plumbed electrically activated fire extinguisher system, again with cockpit and external panic switches.

Specification

The standard specification Lotus Sport Exige Cup 260 is road legal within the European Union, and can be registered for road use. The vehicle is supplied with a separate FIA approved 6-point roll cage and 4-point harnesses. These are for track use only and can be installed by an authorized Lotus dealer at the request of the customer. Other track options are available from Lotus Sport that can be fitted during production. Vehicles fitted with these parts cannot be road registered.

Options (all subject to local taxation rates)

• FIA approved 70 litre fuel cell (track use only)
• Lotus Sport limited slip differential (plate type)
• Air conditioning
• Metallic paint
• Lifestyle paint
• Race battery and holder

Other more hardcore track options are available – prices on application (ie ‘Level Two’ exhaust with de-cat pipe, dog gearbox, Recaro/Lotus Sport driver’s seat with 6-point harness etc).

Lotus Exige Sport 240: Aussie Designed Exige To Debut In Sydney Show

Conceived and designed by Lotus Cars Australia, the special edition Exige Sport 240 is powered by a supped up (and supercharged) version of the Toyota derived, 1.8L VVTL-i 4-cylinder unit which delivers 240hp, or 179kW, a 10 percent improvement over the Exige S. Torque also increases from 215Nm to 230Nm. According to Lotus Australia, the Exige Sport 240 sprints from 0 to 100km/h (62mph) in 4.2 sec, 0-160km/h (100mph) in 9.9 seconds and achieves a top speed of 249km/h (155mph). Apart from the special badgetry, unique features of the Exige Sport 240 include the driver-adjustable stand-alone traction control, similar to systems used in Formula 1 and the standard torque-sensing limited-slip differential. The special edition Exige will be uncloaked at the Sydney show in October where it will officially go on sale for 149,990 AUD or 124,586 USD. -Press release and high-res imagers after the jump

Lotus Exige Sport 240 - Australian Design, F1 Technology, Sydney Debut

Special Edition Exige with extra power and F1-style traction control

Lotus Australia has announced the fastest, most-desirable and exclusively tuned Lotus Exige to ever go on sale in Australia, the Lotus Sport 240.

Conceived and designed by Lotus Cars Australia, the special edition Exige Sport 240 will make its world debut at the Australian International Motor Show in October where it will officially go on sale.

With power improved to 179kW, this will also mark the first production car in Australia fitted with driver-adjustable stand-alone traction control, similar to the systems currently used in Formula 1.

"Designed specifically for Australia, we are excited and proud to add this bespoke Exige to our existing range." said Jonathan Stretton, Sales and Marketing Manager of Lotus Cars Australia. "Cars like the Exige Sport 240 show our passion and commitment to the Australian market."

"This Exige Sport 240 will only be available in Australia. We have worked with the Lotus factory in the UK to select specific styling and performance parts based on what we know will improve performance, but also taking into account customer feedback and current trends in this market.

"The Exige Sport 240 is a car entirely comfortable on the road for everyday use. Take it to the track and it will be blisteringly quick and will outpace cars two or three times the price," Stretton added.

Tuned with more power, bigger brakes, body mods, two bespoke colours, interior changes and limited edition badging, the Exige Sport 240 will be the most exclusive Exige to hit Australian Lotus showrooms.

Just six of the Exige Sport 240 will be initially available in launch colours of Blaze Orange or Sapphire Black, each with a special edition interior plaque.

The Blaze Orange model will feature black highlights, including front splitter, rear wing endplates, wheels and a rear beaver panel infill around the rear lights.

The Sapphire Black model will feature a Chrome Orange front splitter and rear wing endplates.

Both models will feature lightweight Lotus Sport forged five-spoke OZ alloy wheels. The Blaze Orange car has wheels finished in black with the Sapphire Black using silver. This is the first time this wheel design has featured on an Australian model.

Also for the first time in Australia, the signature Exige roof scoop will extend forward from the engine compartment to the top of the windscreen to supply an increased volume of air to the intercooler, whilst also giving the car more visual presence.

Special Exige Sport 240 badging will mark the exclusive model's exterior.

As the name suggests, power output is 240hp, or 179kW, a 10 percent improvement over the Exige S. Torque also increases from 215Nm to 230Nm. Upgraded fuel injectors and a new ECU allow the supercharged engine to reach greater heights.

The engine is a 1.8-litre supercharged intercooled four-cylinder. Features include twin-overhead camshafts, 16 valves and VVTL-i variable cam timing and lift, along with a distinct, characteristic supercharger whine.

A six-speed close-ratio C64 gearbox is standard and has been upgraded with a heavy duty clutch kit including a strengthened clutch and pressure plate.

Putting this extra power to the ground will be assured through mechanical and electronic traction aids. A torque-sensing limited-slip differential is standard on the Exige Sport 240, the first time it has been offered as factory equipment on a Lotus in Australia.

The Sport 240 will also be fitted with Lotus Sport adjustable traction control. Developed from the Lotus Sport UK GT3 motorsport program, the advanced electronic system utilises a driver-adjustable control knob to dial-in one of 18 preset levels of traction control intervention. This allows for the ultimate in driver control in any road condition, wet or dry.

This system also utilises electronic launch-control where the driver can dial in the desired revs, floor the throttle and it will hold at the determined point until the clutch is released for perfect starts every time.

Performance figures are equally impressive with 0-100km/h in 4.2 seconds, 0-160km/h in 9.9 seconds and an estimated top speed of 249km/h.

Lotus is already known for its outstanding stopping power, and the Exige Sport 240 is even more effective with AP four-piston callipers on the front with 308mm two-piece front vented discs and braided hoses. On the rear, new Brembo single-piston callipers work on 288mm rotors. Pagid brake pads are fitted all around.

The suspension uses one-way adjustable dampers with adjustable ride height and an adjustable front sway bar to suit those wanting to tune the car to their own driving style.

Maintaining its track focus, the Sport 240 is fitted with grippy R compound Yokohama A048 LTS tyres, 195/50x16 front, 225/45x17 rear. It also benefits from a BS4 T45 steel roll-over hoop and struts.

The Exige Sport 240's interior hasn't been forgotten and includes the elements of a Touring Plus pack. With this comes air-conditioning and sound insulation amongst other enhancements throughout the cabin. Exige Sport 240 sports seats (finished in black leather) with a harness bar complement the purposeful nature of the car. The seats display an orange Exige logo and, along with the door trims and centre console, also have orange stitching. The black floor mats also feature an orange Exige logo.

Even the air-conditioning system is designed for performance. Weighing just 15kg for the entire system, the air-con uses an advanced clutch that automatically turns the compressor off when it senses full throttle to preserve maximum performance.

The special edition Lotus Exige Sport 240 is priced at $149,990 plus dealer delivery and statutory government charges. It will debut and go on sale at the Australian International Motor Show, from October 11.

The Sport 240 is released in what is the most successful year for Lotus Australia. According to Stretton: "Year-to-date, Lotus Australia has more than doubled its 2006 retail sales. In 2007 we are likely to exceed the highest sales ever in Australia by 20 percent. Adopting a more focused strategy in Australia is serving us well and the introduction of the Exige Sport 240 further emphasises the importance and relevance of Australia for Lotus Cars."
