Lotus announces purpose-built Range Extender Engine

Designed specifically for the new breed of highly efficient series hybrid vehicles, Lotus Engineering’s Range Extender engine was shown for the first time at the 63rd Frankfurt International Motor Show. In a series hybrid vehicle, the Range Extender engine is attached to an electricity generator and provides a highly efficient source of energy to power the electric motor directly or charge the vehicle's battery. The three-cylinder 1.2 liter Range Extender engine is optimized between two power generation points, giving 15 kW of electrical power at 1,500 rpm and 35 kW at 3,500 rpm via the integrated electrical generator. The battery can also power the electric motor which enables the design of a drivetrain with low emissions, optimized performance and acceptable range.
