Lotus Evora 414E Hybrid Concept 2010

The Lotus Evora 414E Hybrid Concept is a technology demonstrator for Lotus Engineering that is a subsidiary of Lotus Cars Limited. The Lotus Evora 414E has a plug-in-series hybrid drive system developed by Lotus Engineering and that is proposed for car manufacturer. The drive system include Lotus developed Range Extender that provides 35 kW/ 47hp at 3.500 rpm via the integrated electrical generator and features an innovative architecture comprising an aluminium mono-block construction, integrating the cylinder block, cylinder head and exhaust manifold in one casting. The combustion engine is an optimized 1,2 litre three cylinder unit. The low mass of the range extender unit (85 kg) and compact package makes it ideal for the series hybrid drive-train in the Evora 414E Hybrid. The name 414E comes from the total power of the two electric motors that is 414 bhp or 306 kW. The electric energy storage is a 17kWh Lithium polymer battery that allows 35 miles range on one charge.

Total hybrid range is estimated over 300 miles/483 km. Acceleration form 0 to 60 mph/97 kph is announced in under 4 seconds.

The two electric motors are driving each of the rear wheels independently via a single-speed gear-train, integrated into a common transmission housing, thus enabling torque vectoring for stability control of the vehicle.
Driver involvement is enhanced by the incorporation of HALOsonic internal and External Electronic Sound Synthesis technologies from Lotus and Harman International, which provide sound contouring within the cabin and improve pedestrian safety outside the vehicle.
