Lotus
2-Eleven Track Car
The
supercharged and intercooled 1796 cc engine in the Lotus 2-Eleven has a maximum
power output of 255 PS (252 bhp / 188 kw) at 8000 rpm and a torque figure of
approximately 242 Nm (179 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
Lotus 2-Eleven features a 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. All this
gives the Lotus 2-Eleven boasts a power to weight ratio similar to that of a
1960's Formula One car.
A
sports-type clutch plate and heavy duty clutch cover transfer the Lotus
2-Eleven's engine power and torque to the lightweight aluminium C64 six-speed
gearbox (with an aluminium casing) – with the same perfectly spaced ratios as
the Exige S. An open type 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 km/h (5 mph) and reacts much
more quickly than many brake-based systems.
The
Lotus 2-Eleven uses a unique high-sided variant of the Lotus Elise lightweight
chassis structure featuring epoxy bonded aluminium alloy extrusions with
modified Exige S based running gear. This strong and stiff package features a
comprehensive safety system with a glass fibre reinforced composite front crash
structure allied to a high sill chassis for side impact protection. Additional
chassis safety features include an FIA compliant 6-point rollover structure
with integral harness mounts and lightweight galvanized steel rear sub frame
incorporating a further crushable structure.
The
Lotus 2-Eleven features all new ultra-lightweight (40 kg / 88 lbs) composite
bodywork featuring core-mat technology. All external panels are bolted on for
ease of removal, maintenance and repair.
