Road Cars Ready for Track Use - Straight out of the Box:
Lotus Sport, the motor sport division of Lotus Cars Ltd., has
developed two higher performance versions of the 2006 Model Year Lotus
Exige, the Lotus Exige Cup and the Lotus Exige Cup 240, both developed
for track use straight out of the box.
The Lotus Exige Cup cars are based on the new 2006 Model Year Exige
and are completely track ready sports coupés with uprated clutch,
sports exhaust, adjustable suspension, uprated brakes, limited slip
differential, switchable traction control, a T45 steel roll-over hoop
and A-frame with harness mounts, fuel and ignition kill switches and a
fully plumbed in fire extinguisher system. An FIA approved 6 point
roll cage is a no cost option*.
As the names suggest, the Lotus Exige Cup cars are available with
two different engine variants. The Lotus Exige Cup uses a 192 PS
(189hp / 141kW) and 181Nm four cylinder 1.8 litre 2ZZ VVTL-i engine,
and the Lotus Exige Cup 240 uses a supercharged and intercooled high
revving 1.8 litre four cylinder engine producing 247 PS (243hp /
181kW) at 8000 rpm and a torque figure of 236 Nm at 7000 rpm.
Performance from both the variants is phenomenal with the Lotus
Exige Cup reaching 100 km/h in 5.2 seconds and 160 km/h in 13.2
seconds, with a top speed of 237 km/h. The Lotus Exige Cup 240 reaches
the 100 km/h mark in around 4.5 seconds and 160 km/h in 11.3 seconds.
Top speed is 249 km/h.**
Both versions are built as official factory conversions of new
Lotus Exige cars by Lotus Sport at its facilities at the Group Lotus
Headquarters in Hethel, Norfolk, UK. Each car features a Lotus Sport
build plate.
The specifications in more detail:
Apart from the differences in engine performance, the Lotus Exige
Cup cars have identical specification.
Engine
The Lotus Exige Cup uses a 192 PS 2ZZ-GE 1.8 litre VVTL-i (Variable
Valve Timing with Lift - intelligent) engine. This high revving engine
is governed to a maximum engine speed of 8500 rpm with a change
between two cams (a high speed cam and a low speed cam) at between
5800 rpm and 6200 rpm depending upon the operating conditions of the
car.
The supercharged and intercooled engine in the Lotus Exige Cup 240
has a maximum power output of 247 PS (243 hp / 181 kW) at 8000 rpm and
a torque figure of 236 Nm at 7000 rpm. This vast amount of extra power
and torque now available means that the cam change between the
low-speed cam and the high-speed cam now takes place at around 4000
rpm giving a smooth and linear surge of power from 4000 rpm all the
way to the maximum 8300 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.
Charge air (air under pressure from the supercharger) is cooled
through an air-to-air intercooler (the cooling air enters via the roof
scoop) before being fed into the engine itself. 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. Four high capacity injectors add
additional fuel under hard acceleration or high speed driving.
A sports-type clutch plate and heavy duty clutch cover transfers
the engine power and torque to the lightweight C64 six-speed gearbox
(with an aluminium casing) - with the same perfectly spaced ratios as
the standard Elise 111R and Exige.
A torque-sensing type limited slip differential is fitted as
standard and works in harmony with the Lotus switchable traction
control system. The system works though the engine, reducing power to
maintain traction, is active above 8 km/h and operates much more
quickly than many brake-based systems.
An Accusump (engine oil accumulator unit) is included in the whole
package as an oil reservoir backup for extreme track use ensuring
that, under these conditions, the engine oil pressure remains
constant.
Wheels and Tyres
Y-type 8-spoke lightweight cast alloy wheels in High Power silver
are shod with Lotus specific Yokohama Advan A048 tyres (rated W and
annotated with "LTS") to maximise grip and achieve the ride and
handling targets set by Lotus.
Brakes
The brake system includes cross-drilled and ventilated discs and
upgraded sports brake pads set into the brake calipers (AP Racing on
the front and Brembo on the rear), high grade silicon brake fluid,
stainless steel braided brake hoses all linked to the proven Lotus
track tuned servo-assisted four-channel ABS system that enhances
braking performance and minimising stopping distance without taking
over from the skill of the driver.
Suspension
Suspension is provided by Öhlins springs and two-way adjustable
dampers (which have 22 compression and 60 rebound settings and ride
height adjustment to reduce the ride height from 130 mm to 120 mm) and
an adjustable front anti-roll bar (five settings). Full instructions
and recommended settings are provided to allow customers to tailor the
handling characteristics of the car to their own requirements.
As the Lotus Exige Cup cars are modified for track use, a double
shear track control arm brace is provided to cope with the expected
kerb abuse during racing and hard track day driving.
Safety Equipment
The Lotus Exige Cup cars have all the safety equipment that is
expected for a track car with 4 point seat belt harnesses (for track
use only), two sports seats clad in suede-effect material and using
ProBax technology, a T45 steel roll-over hoop and A-frame with harness
mounts, a mechanical ignition kill switch with cockpit and external
activation and a plumbed electrical fire extinguisher system, again
with cockpit and external activation. A FIA approved 6-point roll cage
is a no cost option, race ready for customers wishing to compete in
motorsport activities.
Interior
The interior makes use of lightweight and simple race specification
materials including aluminium window winders, acrylic capped door
panels and carbon-effect leather door inserts.
Exhaust System
A "Level One" stainless steel sports exhaust is fitted with the
bifurcated exhaust pipes exiting from the centre of the
anodised-finish 3-piece rear diffuser. Front driving lamps, twin oil
coolers and air conditioning* complete the equipment package for the
Lotus Exige Cup cars.
The Lotus Exige Cup has a Recommended Retail Price of EUR47,621+VAT
in mainland Europe and CHF83,948 including all taxes in Switzerland.
The Lotus Exige Cup 240 has a Recommended Retail Price of £45,995
in the UK, EUR56,034+VAT in mainland Europe, and CHF101,026 including
all taxes in Switzerland.
