The Exige 270E Tri-fuel is part of Lotus' research to understand the complex combustion process involved in running on mixtures of alcohol fuels and gasoline, which will be important for a successful transition from today's fuels to the sustainable, synthetic fuels of the future.


The heart of the Exige 270E Tri-fuel is a Roots-type supercharger (with a sealed-for-life internal mechanism meaning that it does not require the use of the engine's oil) and air to air intercooler attached to the tried and tested 4-cylinder, 1.8 litre 2ZZ-GE VVTL-i engine. Using a development of the supercharger and intercooler package from the Exige S, the Exige 270E has peak power of 270 HP (201 kW) at 8,000 RPM, 184 lb/ft (260 Nm) of torque (at 5,500 RPM) up by 51 HP (38 kW) or 19% and 25 lb/ft (45 Nm) or 21% over the standard gasoline Exige S. Maximum engine speed is 8,000 RPM (8,500 RPM transient for up to 2 seconds).
