2008 Lotus 2-Eleven

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 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.

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 an aluminium casing) with the same perfectly spaced ratios as the Lotus 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.
