Yes I know its anouther hydrid design but this one looks like its pushing the boundaries and I find it exciting because its by one of my favourite car makers - Lotus.
According to the Norfolk-based car maker, the three-cylinder 1.2l engine has been optimised to perform at two power generation points, developing 15kW (20bhp) at 1500rpm and 35kW (47bhp) at its maximum 3500rpm via an integrated electrical generator. Peak torque of 107Nm (79lb ft) is generated at 2500rpm.
The engine is made entirely of aluminium, with the cylinder block, cylinder head and exhaust manifold all part of a single casting. Dry weight is given as 56kg (123lbs) including the generator.
The engine has been developed by Lotus as part of the Limo Green project, which also numbers Jaguar Land Rover, the Motor Industry Research Association (MIRA) and Caparo Vehicle Technologies among its supporters.
