Lotus Range Extender Engine headed for market
Lotus Engineering has announced plans to develop its Range Extender Engine for series production. First shown at the 2009 Frankfurt Motor Show, the Range Extender is a 1.2 liter, three-cylinder engine designed specifically for series hybrid vehicles.
Producing 35 kW (48 PS/47 hp) of power at 3,500 rpm and weighing just 56 kg, the Lotus Range Extender runs on alcohol-based fuels and/or gasoline and provides power to an electric drive system via an integrated generator which charges the batteries.
The low weight is achieved through an innovative aluminum monoblock construction which the cylinder block, cylinder head and exhaust manifold are produced in one casting.
