Lotus Launches the Exige GT3 Concept Road Vehicle

UNLEASHED! The Most Extreme Exige Variant To-date

 

Geneva, Switzerland (6th March 2007), Lotus Sport, the race car performance arm of Lotus

Cars Ltd, today unveiled the Lotus Exige GT3 concept road vehicle. With its debut at the 77th

annual Geneva International Motor Show, the 275 PS (271 bhp / 203 kW) Exige GT3 is a bold,

no-holds-barred, lap record-breaking, breathtaking performance machine that embraces all

that is expected of a race-bred Lotus.

Building on the Lotus racing pedigree, this concept car can deliver more grin-factor than ever

before; there are no intended compromises and no limits except those that are self imposed by

the driver.

This is one concept that commands your full attention.

Said Mike Kimberley, Chief Executive Officer for Group Lotus plc:

“The Exige GT3 concept road car is a fantastic showcase product from our race car

performance division, Lotus Sport. The car’s racing background becomes immediately

obvious from its aggressive stance, extreme width of rear track and innovative threedimensional

rear wing. The foundation of all Lotus products is phenomenal handling and ride

characteristics, but the Exige GT3 takes these into another dimension altogether where

supreme road holding and outrageous acceleration come evenly matched with sensational

stopping ability.”

The Exige GT3’s pure bred racing brother will be again competing in the GT race arena in

2007, taking over the mantle from the hugely successful 2006 British GT3 Championshipwinning

car. On road or track the Lotus Exige GT3 winning pedigree will continue in time

honoured Lotus racing tradition.

A new one-piece front clam-shell with fully masked front wheels and wheel arch venting leads

the aerodynamically cleaned silhouette of this car. A menacing stance is enhanced by the

aggressively flared rear wheel arches and aero-efficient three-dimensional rear wing and

blended end-plates. The visual message is clear; this vehicle means business and the squat

wide hindquarters symbolise the latent power harnessed within.

That power is provided by the same charge-cooled supercharged engine that the GT3 race car

employs, producing 275PS (271bhp / 203kw) driven through ten inch rear wheels with 255

width tyres making the final connection to the road. Max speed (257kph / 160mph) and peak

torque have been electronically limited but acceleration is left untouched and unimpaired. The

up-rated front brakes and brake pads all round ensure that on road or track this car’s stopping

ability is more than capable of harnessing its acceleration performance.

The end-plate mounted three-dimensional rear wing is highly efficient and fully complements

the widened and flattened rear deck shape in reducing the overall drag as well as maintaining

front to rear downforce balance. The performance of this car will amaze and reward all drivers

with incredible road holding (developed with the help of its 2-way Ohlins adjustable dampers

together with Lotus Sport adjustable front stabiliser bar and rear suspension double-shear

track control arms) and stunning acceleration.

Simply put, the Lotus Exige GT3 will redefine your concept of a road car by re-affirming that

unique proposition that is, above all else, a Lotus.

It is intended that the Lotus Exige GT3 concept road vehicle will be further developed into a full

production car for limited markets, to go on sale in late 2007 with an estimated price tag of

between £50,000 and £60,000.


  

The Lotus GT3 in more detail

Engine

The supercharged and intercooled 1796 cc engine in the Lotus GT3 has a maximum power

output of 275 PS (271 bhp / 203 kw) at 8000 rpm and a torque figure of approximately 258 Nm

(190 lb/ft) at 7000 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. 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. Four high capacity injectors and an up rated fuel pump add additional

fuel under hard acceleration or high speed driving.

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.

Twin oil coolers complete the powertrain package.

Transmission

A sports-type clutch plate and heavy duty clutch cover transfer the engine power and torque to

the lightweight aluminium C64 six-speed gearbox – with the same perfectly spaced ratios as

the Exige S. An open type limited slip differential is fitted as standard. The Lotus switchable

traction control system (LTCS) works through the engine, reducing power to maintain traction;

it is active above 8 kph (5 mph) and reacts much more quickly than many brake-based

systems.

Chassis Structure

Lotus designed lightweight structure of epoxy bonded aluminium alloy extrusions with crash

structure, extruded aluminium door beams, integral steel seat-belt support structure and

lightweight galvanized steel rear sub frame incorporating a structural shear panel.

Body

GT3 derived one-piece front clamshell and wide track rear clamshell with full length roof scoop

design taken from the Cup Exige 255. New full width rear wing with integral end plates

mounting to rear clam. Race style full width front splitter; standard Exige door and body sides

retained. Multi element rear diffuser with carbon option.

Wheels & Tyres

5-spoke lightweight forged alloy wheels (front 7Jx16 and rear 10Jx17) are shod with Lotus

Sport specific Yokohama A048 R LTS tyres (front 195/50 R16 and rear 255/40 R17), designed

to maximise grip and achieve the ride and handling targets set by Lotus.

Brakes

The brake system includes 308 mm diameter 2 piece aluminium belled cross drilled and

ventilated front discs and 288 mm diameter cross-drilled and ventilated rear discs. AP Racing

two-piece radially mounted 4 piston calipers at the front and Brembo single sliding piston at

the rear. Pagid RS14 sports brake pads all round. High grade silicone brake fluid; stainless

steel braided brake hoses. In addition, the proven Lotus track tuned servo-assisted fourchannel

ABS system enhances braking performance and minimises stopping distance without

taking over from the skill of the driver.

Suspension

Fully independent suspension utilising unequal length wishbones; Öhlins 2-way adjustable

dampers with coil over springs and Lotus Sport adjustable front anti-roll bar. A rear double

shear track control arm brace is provided to cope with the expected kerb abuse during heavy

track day driving.

Performance

0-60 mph 3.9 secs (estimated)

0-100 km/h 4.0 secs (estimated)

0-100 mph 9.8 secs (estimated)

(0-160 km/h)

Maximum Speed 160 mph (257 km/h) - electronically limited

Max Power 275 PS (271 bhp / 203 kw) at 8000 rpm

Max Torque 258 Nm (190 lb/ft) at 7000 rpm (electronically limited)
