• Range Extender Engine. This all-aluminium, monoblock, 1200 cc, three-cylinder, 47 horsepower, four-stroke engine is specifically designed to directly drive an alternator for electricity generation for series-hybrid cars. The engine is small and light at 56 kg (123 lb), having three cylinders and no detachable cylinder head. The cylinder head and engine block are all one casting to reduce size, weight and production costs. As the engine does not turn belt driven ancillaries such as alternator, power-steering pump or an air conditioning compressor, the block requires no strong points to accommodate such ancillaries, resulting in a simple and light block. The engine has a reduced parts count for lightness and cheaper production.
• On 18 August 2011 Lotus fired up an all new in-house designed V8 destined for the new era range of cars. At 170 kg (375 lb) and just 612 mm (24.1 in) long, the unit will be dry sump lubricated to save depth and will feature a 180° flat plane crank. The engine is being utilised as a stressed component, a technique pioneered by Colin Chapman in F1, specifically with the 1967 Type 49. It is expected to be used in the Le Mans LMP2 car in 2012. Expected performance is likely to be in excess of 590 PS (434 kW; 582 hp) and with a 9,200 rpm redline.
