Lotus Elise: Lotus Sport Exige

470 hp/tonne Race Ready Sport Exige Debuts at Autosport International Show

Lotus Sport, the performance division of Lotus Cars Ltd., has developed the new Lotus Sport Exige, a direct motorsport derivative of the successful Lotus Exige.

The Lotus designed and engineered racecar was part manufactured by RTN, the team responsible for the Le Mans winning Bentley, using the latest motorsport techniques and procedures to produce a lightweight yet strong carbon-fibre bodywork structure around the standard road-going Lotus Exige Aluminium extruded and bonded chassis.

The Lotus Sport designed fully adjustable suspension system with double wishbones all round was fabricated and manufactured by Pilbeam. Power is provided by a 400 hp Swindon Racing Engines tuned GM 3 litre V6 racing engine linked to a Hewland sequential six-speed gearbox, with AP-Racing providing the braking system.

This one-off racecar has been built for a South East Asian client and is expected to race in selected sportscar races in Asia. There are no plans as yet to build further examples of the Lotus Sport Exige but the base structure has been carefully designed to comply with key motorsport regulations around the world. Adhering to the key Lotus philosophy of performance through lightweight, the Lotus Sport Exige weighs in at just 850kg.

The whole project, conducted in complete secrecy has taken less than 6 months and the car will run for the first time at the 2? mile Hethel test track in mid January.

Chris Arnold, General Manager for Lotus Sport explains the philosophy behind the Lotus Sport Exige:

"The Lotus Sport Exige is a competition car developed directly from the road going Exige. The racecar uses the existing tub with only minor modifications, and careful design has enabled Lotus Sport to package an upgraded powertrain assembly whilst maintaining an equivalent weight to the existing road car. When this package is combined with further improvements to suspension and bodywork, it produces a fantastic looking car with great track potential.

The car has been taken from concept to reality in only six months and I thank all our engineering partners and the staff at Lotus who have worked so hard on this fantastic project."

As the Lotus Sport Exige is, at present, a one-off racecar, a price cannot be given for the racecar package.

The Lotus Sport Exige in more Detail:

Chassis and suspension systems

The Lotus Sport Exige is directly developed from the road-going Lotus Exige that was unveiled at the Geneva Motorshow in 2004. The heart of the Sport Exige is the bonded and extruded Aluminium Chassis, the technology for which was first introduced in the Lotus Elise in 1995. The Exige chassis, which is also used in the Lotus Elise 111R, is the latest development of this award winning structure and weighs 68kg and has a torsional stiffness of 10500 Nm/degree. Made up of 25 separate extrusions, and bonded with an epoxy adhesive, the chassis in the Lotus Sport Exige is an exceptionally stiff, strong and lightweight structure. This Lotus technology is so world-leading that it has been used on other non- Lotus products including high performance production front-engined V12 and V8 GT cars.

An FIA approved 8-point roll cage has been bolted to the chassis, prior to the bodywork being fitted.

Double wishbone front suspension is mounted to the same suspension hard points as the road-going Lotus Exige, whilst the rear suspension picks up to a revised rear subframe. However, being a full racecar, there is adjustment for ride height, camber and castor, as well as adjustable front and rear anti-roll bars. Coil springs are mounted over Ohlins ST44 3-way adjustable dampers front and rear.

The Body

Lightweight "Z-Preg." carbon fibre bodywork was specially manufactured for Lotus by RTN, the team responsible for the Le Mans winning Bentley. These panels (front clam, "A" panel, body side and sill, roof, engine cover and rear clam) have been made using an innovative low temperature curing process. The moulds were taken directly from the Sport Exige styling "clay" and the resulting carbon fibre panels are race-ready without having to rely on the costly tooling process used in current carbon fibre technology. This is thought to be the first time that this technology has been used on such large carbon fibre panels.

An aerodynamically developed front splitter, carbon fibre rear diffuser and an adjustable carbon rear wing provide increased levels of downforce. The interior of the Lotus Sport Exige is similar to the standard Exige, but the standard roadcar wiring harness is replaced with a full Raychem 25 system incorporating Mil-spec connectors from Beru Formula 1 Harnesses. Conventional fuses are replaced with circuit breakers, and a Stack display with integrated data recording is fitted as standard.

A racing bucket seat (driver side only) is mounted as right hand drive to optimise weight balance through right hand corners (most circuits run clockwise). A six-point seat belt, prepared for using HANS Safety System, and a removable steering wheel (with quick-connect coupling) is included in the interior package.

The composite energy absorbing crash structure used on the standard road cars is also carried over to the Lotus Sport Exige. This glass fibre composite structure, around five times more energy absorbing than the equivalent steel component, also houses the larger water radiator and provides efficient cooling and air ducting over the carbon front clamshell.

A 100 litre FT3 safety fuel cell (with quick refuelling system) is mounted behind the driver and in front of the engine (as with the road-going Exige). A fully plumbed in electrical fire extinguishing system completes the body package.

Brakes

AP Racing provides the non-ABS braking system, which includes the pedal box (with brake balance bar and cylinders). AP Racing also provides the powerful six piston brake calipers at the front and four piston brake calipers at the rear. These calipers are mated to vented discs (344 mm diameter at the front and 330 mm diameter at the rear).

Rims and Tyres

Ultra lightweight OZ Racing Chrono single-piece cast magnesium rims (8.8J x 17 ET40 at the front and 11.25J x 18 ET50 at the rear) are shod with Yokohama tyres (250/610-17 at the front and 280/650-18 at the rear).

Powertrain: Engine and Transmission

A narrow angle V6, 2,998 cc Swindon Racing Engines tuned GM racing engine is mounted longitudinally in the Lotus Sport Exige. The naturally aspirated 32-valve engine produces 400 hp (296 kW or 405 PS) at 7,750 rpm and 294 lb.ft (398 Nm or 40.6 kgm) of torque at 6,500 rpm and has a maximum engine speed of 8,250 rpm. When the light weight of the Lotus Sport Exige is taken into consideration, the power to weight ratio is a phenomenal 470 hp / tonne (0.351 kW/kg or 476 PS/tonne). The engine itself weighs 157 kg.

Breathing is via an F1-style airbox and air snorkel from the roof panel of the Sport Exige directly into the six carbon fibre air trumpets.

The dry-sump engine, with a bore of 89.0 mm and stroke of 93.7 mm is water cooled and also uses an oil-water heat exchanger to efficiently cool the oil. The whole engine is controlled by a Motec M600 electronic engine management system fitted inside the cockpit.

The power is transferred from the engine to the rear wheels via a single mass stepped flywheel, AP Racing twin-disc cerametallic race clutch and Hewland NLT sequential six-speed dog type transmission (with in-line shift mechanism). The gearbox itself is cooled through an oil-water heat exchanger. A limited slip differential (separate power and brake ramp angles) completes the powertrain package.

Design

The one-off racecar has been designed by Barney Hatt (Principal Designer for Lotus Design), under the direction of Russell Carr (Chief of Design). Taking the already aerodynamic road going Exige, Hatt designed the Lotus Sport Exige with the requirements to carry the design of the Exige and the brand attributes of Lotus into a competitive racecar.

Russell Carr explains the work needed to design the Lotus Sport Exige: "The objective was to create a dramatic design and to take into account aerodynamic criteria to produce a race car that was not only competitive but also stunningly good looking. General motorsport regulations also had to be adhered to so the fact that the resulting racecar looks like a natural competition evolution of the road going Exige is a testament to the purity and effectiveness of the original design."

Dimensions

The Lotus Sport Exige is slightly longer (350 mm) and wider (100 mm) than the road-going Exige to accommodate the larger engine, wider track, longer wheelbase and to optimise the aerodynamics. The length is mainly from the cockpit rearwards but the short rear overhang design of the road-going Exige is maintained.

That is so sick.

The car is so far beyond the abilties of most drivers, you'd practically have to be an F1 or rally driver to be able to use it. I'd certainly have fun trying though.

You bet. Just the regular Elise is pretty tricky, I can only imagine what this one would be.

At the LA Auto show, in the aftermarket section, I saw two Lotus Elises with K20s dropped into them. One of them was even running a supercharger with the K20, so it was pushing 300 hp. It stated that it could do 0-60 in 2.9 seconds. Now that's some scary shit.

This Lotus?




The little paper on the windshield says, 338hp and 215lb-ft of torque @ 10.5(?) psi. 0-60 in 2.9 and 0-100 in 7.2

It was made by Prototype Racing. If the pictures don't show, you can find it at http://www.prototyperacing.com altho, on the site apparently it hasn't been updated to the stats provided on the windshield.

This car will run circles around others that cost 5X as much (kind of like how the Mitsubishi Evo 8--which although not cheap--gave a Murcielago a run for its money on Top Gear)...

Too bad Lotus' recent cars are ugly as they come. Very brutish, but hey, 2.9s to 60 is pretty damn brutish too.

You think the Exige/Elise cars are ugly? I always thought everyone liked their look...

I can appreciate them for what they are, even looks-wise, but I can't ignore that they're overdone. There's good quirky styling (Zonda) and there's questionably quirky styling (Lotus' recent cars).

Lotus Sport Exige 240R News





Limited Edition Lotus Sport Exige 240R

Lotus Sport, the performance division of Lotus Cars Ltd., has developed the Lotus Sport Exige 240R, a limited edition high performance sportscar with total global build volumes kept strictly to 50 cars.

Lotus Sport will build the Lotus Sport Exige 240R within its facilities at the Group Lotus Headquarters in Hethel, Norfolk. This facility, located in the centre of the famous Hethel Test Track, has a great history of producing bespoke versions of Lotus products and can list the Lotus Sport Exige 400 hp racecar and over 100 Elise and Exige racing cars in its portfolio.

With a supercharged and intercooled high revving engine producing over 240 hp and over 170 lbft of torque, the Lotus Sport Exige 240R reaches 60 mph in less than 4 seconds and 100 mph (160 km/h) in less than 10 seconds before topping out at 155 mph (249 km/h). At this top speed the advanced aerodynamics produce 113 kg of downforce increasing grip, stability and safety.

The 50 versions of the Lotus Sport Exige 240R will be built as post registration official factory conversions of new Lotus Exiges. Up to 40 of these cars will be sold in the EU and the balance is intended to be predominantly sold in Japan. The suffix of 240R indicates the approximate horsepower of the engine, conservatively rounded down from the actual figure of 243 hp (181 kW, 247 PS). The total unladen weight is approximately 930 kg and the power to weight is approximately 261 hp / tonne (195 kW / tonne, 266 PS / tonne).

All 50 cars will be built to order and to further identify and maintain the exclusivity of the Lotus Sport Exige 240R, they will only be available in Sport Yellow or Sport Black – both unique and exclusive colours specifically blended to denote the brand colour scheme of Lotus Sport.

The Lotus Sport Exige 240R will be sold at a Recommended Retail Price of £43,995 (62,000 Euros).

WCF Test Drive: Lotus Exige 240R

Limited Tradition

The 240R is the ultimate Exige and may just be too good for the public road…

When a car sells out before it even hits the market, you know you’re dealing with something special. All 50 Lotus Exige 240Rs are already gone and Lotus claims they’ll never sell anymore. So if you were a bit slow on the uptake, forget about it.

Still, the claim from the men in Norfolk that there would be no other supercharged Exiges didn’t ring true even then, all that technology for 50 cars didn’t compute. And now before this even goes to press the Exige S is with us, with 218bhp, but it’s no 240R.

The original Exige carved itself a place in motoring folklore. The original car could match machines 10 times its price round a race track, so is this £43, 995 version that much better? Well, yes.

Strapping a Rootes-type Eaton M62 supercharger to the Toyota-sourced 1800cc engine, together with new pistons, cams, rods and other trick bits from the Toyota parts bin, has produced a 243bhp powerplant. That’s not huge, less than a Porsche Boxster, but then this car weighs just 930kg and that’s half as much as Porsche’s more sensible daily driver.

Lotus has stayed true to the guiding principle of founder Colin Chapman: “Just add lightness.” He took it to extremes, though, when he entered Formula One in 1958. If a component on Chapman’s cars wasn’t on the point of failure at the end of each race, he ordered a lighter one for the next Grand Prix.

Driving a Lotus racing car wasn’t a job for the faint of heart, but Jim Clark, Graham Hill, Emerson Fittipaldi and Mario Andretti all stormed to Drivers Championships in his machines. Chapman was credited with some of the most exciting breakthroughs in racing technology, including ground-effect aerodynamics, but weight saving was always a central theme.

You don’t need a 500bhp engine if the car weighs less than an anorexic gnat and the handling advantages of a lightweight car are immense.

This car comes with a leather-clad carbon-fibre seat and the extruded chassis and gearchange lights hint at track purpose.

Some roadgoing comforts have been included, though. The new 240R comes with air-conditioning, electric windows, a four-speaker Blaupunkt stereo and even a jack-point for an MP3 player

It’s heavier than the standard 875kg Exige, but nearly 30% more power swallows up the weight of that added kit and more. If you’re only intending to use the car on track you might be tempted to go for the Exige S sport edition, but this is still the quickest one.

This car reaches 60mph in 3.9sec and 100mph in a shade under 10sec. And while the standard Exige suffers a dip in power between 5000 and 7000 revs, this one is tuned to encourage the driver to use every single one of the 8200 revs on offer.

As the Toyota powerplant reaches its crescendo the noise through the cockpit from that screaming four-cylinder and laboured Supercharger is like a shrieking mechanical cat. It’s a high-strung powerplant, and that suits the character of the new Exige perfectly.

This car borrows the Formula One philosophy of high power at high revs and has just 174lb ft of torque at 7000rpm.

This accounts for the alarming way the 240R acquires speed. With this lightweight, low torque motor, there is no sudden kick in the back or wall of power building from behind as the weight shifts and the engine tries to tear through the front of the car. It puts the power down so cleanly, without a hint of wheelspin, that it doesn’t even feel hurried. This, the most powerful Exige yet, actually feels like it could handle a good few more horses.

There is no weight to shift. So under hard acceleration the engine, that is clearly visible through a sheet of clear Perspex in the rear of the car, wiping out all rear visibility, simply goes from loud to insane and the needle whips round in the rev counter binnacle. It doesn’t feel dramatic at all on smooth tarmac, and even on rougher stuff it is more composed than a pared down road racer of this ilk has any right to be. .

The small racing-style steering wheel thrashes like a shark in a net and takes a firm hand to keep on the straight and narrow. It feels connected directly to those front wheels that describe the road on a cellular level with constant and sometimes violent tugs at your hands.

It crashes, fidgets and bounces off every rut, ridge and weed in the road. This is a car that needs steering with the shoulders. It doesn’t need big inputs, the tiniest move is enough to change direction slalom style, but the constant kickback takes its toll on a long frenetic drive.

It’s a hard physical workout driving anywhere near its stratospheric potential, this car stretched my muscles, tested my nerve and felt just as involving as any single-seater I’ve driven.

The 240R has full-bore track suspension with two-way adjustable remote dampers with a mind-boggling 22 compression and 60 rebound settings. A seven-setting, adjustable front anti-roll bar plus a fixed anti-roll bar complete the package.

Lotus recommends a range of settings/stroke parameters to work within. Adjustment to both dampers and roll bar is very simple and you can switch between road and track in a matter of minutes.

Aerodynamics, too have been honed for the track. The 240R generates 21.9Kg at the rear and 19.3Kg at the front at 100mph – generated by the front splitter, air scoop on the roof, the rear wing and ground-effect diffuser. It’s enthralling to feel how Chapman’s work in F1 has passed down through the generations and evolved into this.

Because of the aerodynamics there is not a big window for error in the corners, this isn’t a machine you’ll be able to rescue if it all gets out of hand. Go in too fast, break the aero grip and the car will spear off the road in a heartbeat. The satisfaction with the Exige is working within its prodigious limits and scything smoothly through bends, try and push the car into unnatural mid-corner acrobatics and it will bite you.

The front tyres, super sticky Yokohama numbers, are actually wider on the front than the back to combat oversteer. You can provoke it into going broadside by lifting off suddenly midcorner, before pouring on the power, but this is a car for those that have evolved from such cheap thrills on to a more subtle yet just as manic high – pure unadulterated speed.

It will hold lines that would have most modern sportscars disappearing into the nearest hedge in a cloud of tyre smoke. It just shouldn’t stick to the track at those speeds, but it does.

This car is so capable it will make you look far better than you are, but to take the car to its limits you’ll need to hit the circuit. I didn’t get close on the roads round Norfolk and we were still going way faster than was necessarily a good idea on unfamiliar turf.

Here is where the lightweight nature of this car makes sense, when all the creature comforts of much heavier supercars seem like ugly compromises. It’s a stripped out track and weekend toy, nothing more, and it doesn’t need a boot, back seats or any other creature comfort to justify its existence. It’s a warrior to be taken out of the garage only for X Rated thrills..

The much cheaper Elise may well return much more satisfaction per € to such owners, but for experienced Lotus hands that want the ultimate in grip and performance, this has to be the one.

And that’s a shame as, like I said at the start, it’s all sold out…

Why not put a k20 in an Elise rather than buy an Exige. I did see the vid of the k20 powered lotus, and yes it was quite nice . I guess if I or anyone asked enough on Clubsi it would be posted again.

Cool 2006 Lotus Exige 265E Concept





Press release:

Lotus Exige on Bio Fuel

The Lotus Exige 265E is the most powerful road version of the Lotus Exige ever, and it runs on environmentally friendly Bio Fuel.

Lotus Engineering has developed a bio-ethanol E85 version of the Lotus Exige. The research vehicle is a true Lotus (it weighs just 2050 lbs unladen) and is called the Lotus Exige 265E. 265 indicates the approximate horsepower and is consistent with the naming strategy of other one-off and limited run Lotus variants such as the Lotus Sport Exige 240R; the E indicates the environmentally favorable bio-ethanol E85 fuel (85% ethanol alcohol and 15% petrol / gasoline) that powers this extremely high performing sportscar.

Key to this performance is a slightly modified version of the 2ZZ VVTL-i supercharged and intercooled high revving 4-cylinder engine from the standard Lotus Exige S. This now gives an estimated set of performance figures that would thrash the majority of "Super-Unleaded" performance cars: 0-60 mph in 3.88 seconds, 0-100 mph in 9.2 seconds and a top speed of 158 mph! In fact, the Lotus Exige 265E is probably the world's quickest road-legal E85 bio-ethanol car.

Key changes have been made to the fuel system, the engine calibration and the four fuel injectors mounted on the inlet manifold have been enlarged. Two additional fuel injectors have been fitted at the supercharger inlet to increase the amount of fuel being injected in to the engine under higher engine loads and to further cool the charge air prior to combustion.

What is Bio Ethanol E85?

Bio-ethanol E85 is a fuel which is a mixture of 85% ethanol (an alcohol) and 15% petrol / gasoline. The bio-ethanol can be made from bio-mass plant crops such as cereals, sugar beet, sugar cane and wood. As these plant crops grow, they absorb carbon dioxide from the atmosphere, which then partly offsets the carbon dioxide (CO2) emissions produced during the burning of the bio-ethanol fuel in the car's engine.

The Benefits of Bio-Ethanol

The beauty of ethanol is its ability to produce more power in the engine than with conventional petrol / gasoline fuel. The Lotus Exige 265E now produces 264 bhp at 8000 rpm, and 184 lb-ft of torque at 5500 rpm, up by 46 bhp or 21% and 25 lb-ft or 16% over the standard petrol / gasoline Exige S.

Ethanol has less stored energy per unit volume than gasoline so the fuel economy is less, however as E85 ethanol is 85% sourced from renewable bio matter, there is a net reduction in carbon dioxide (CO2).

The Lotus Exige 265E is purely a research vehicle for Lotus Engineering and Lotus does not intend to put the car into production or sell aftermarket kits for Lotus Cars.

Very hot! I've been looking at the Elise, and it has made the cut to the final 3 roadsters... I've love to get an Exige... but looks like the Elise will be more practical for me...
