* 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 {{Convert|56|kg|lb|0|abbr=on}}, 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.<ref>{{cite web|last=Abuelsamid |first=Sam |url=http://green.autoblog.com/2010/06/22/lotus-and-fagor-ederlan-group-to-produce-range-extender-engine/ |title=Lotus and Fagor Ederlan Group to produce range-extender engine – Autoblog Green |publisher=Green.autoblog.com |date=22 June 2010 |access-date=30 September 2010}}</ref><ref>{{cite web|url=http://www.lotuscars.com/gb/engineering/range-extender-engines |title=» Home – Lotus Engineering |publisher=lotuscars.com |access-date=30 September 2010}}</ref>
* On 18 August 2011 Lotus developed an all new in-house designed V8 destined for the new era range of cars. At {{Convert|170|kg|lb|0|abbr=on}} and just {{Convert|612|mm|in|1|abbr=on}} long, the unit is 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 was expected to be used in the Le Mans LMP2 car in 2012. Expected performance is likely to be in excess of {{Convert|590|PS|kW hp|0|abbr=on}} and with a 9,200 rpm redline.<ref>{{cite web|url=http://www.thelotusforums.com/6374/latest-news/lotus-cars-news/lotus-fire-up-all-new-in-house-v8/ |title=[VIDEO&#93; Lotus fire up all new in-house V8 |publisher=The Lotus Forums |date=16 September 2011 |access-date=18 December 2011}}</ref>
