The Speedster’s intelligent, lightweight design is complemented by a highly efficient all-aluminum engine. The ECOTEC 2.2 16V four-cylinder engine produces
147 hp and maximum torque of 203 Nm at 4000 rpm, 90 percent of which is already available at 1900 rpm.

Combining a chassis made of bonded, extruded aluminum sections with bodywork made of bonded panels reinforced with fiberglass allowing an extremely low vehicle weight of 945 kg while retaining high strength. This technology also provides excellent passive safety for the passengers, because they are surrounded by a stable aluminum chassis.

The Speedster is assembled by Lotus Cars in Hethel, about 150 kilometers north east of London.
