Lotus Engineering Limited is an [[Corporate spin-off|offshoot]] of Lotus Cars, which provides engineering consultancy to third-party companies primarily in the automotive industry. As well as [[Hethel]] in the United Kingdom Lotus has engineering centres in [[Ann Arbor]], USA, [[Kuala Lumpur]], Malaysia and Shanghai, China. In 2000, Lotus Engineering, Inc. was established with an office in [[Ann Arbor]], Michigan.<ref>[http://www.lotuscars.com/engineering/en/centres Lotus Engineering Centres] {{webarchive|url=https://web.archive.org/web/20101005011227/http://www.lotuscars.com/engineering/en/centres |date=5 October 2010 }}, retrieved 18 June 2010.</ref>

=== APX and VVA===
{{Main|Lotus APX}}
The APX (also known as the "Aluminium Performance Crossover") is an aluminium [[concept vehicle]] revealed at the 2006 [[Geneva Motor Show]] built on Lotus Engineering's [[Versatile Vehicle Architecture]] (VVA).

Whereas the VVA technology was to be used in the development of a new mid-engine sportscar for Lotus cars, the APX is, in fact, a high-performance 7-seat MPV with four-wheel drive and a front-mounted V6 engine from Lotus Engineering's Powertrain division. The engine was designed and developed to be available in a 2.2-litre naturally aspirated and 3.0-litre supercharged variations. An electric version was also shown in the 2007 NADA show.

Versatile Vehicle Architecture (VVA) is an effort by the Lotus car manufacturing company to reduce the investment needed for producing unique, niche-market cars by sharing a number of common components.

Cars produced using VVA:

=== Projects undertaken by Lotus Engineering ===

Examples of work undertaken by Lotus Engineering include:

* Lotus [[Talbot Sunbeam]]—Talbot's [[hot hatch]] rally car of the early 1980s
* [[DMC DeLorean]]. Changes to the original concept led to considerable schedule pressures. The car was deemed to require almost complete re-engineering, which was turned over to engineer [[Colin Chapman]], founder of Lotus. Lotus replaced most of the unproven material and manufacturing techniques with those then employed by Lotus in the [[Lotus Esprit]]
* [[Vauxhall Lotus Carlton]] (also Opel Lotus Omega, internal name Lotus Type 104) – At the time (early 1990s) this was the fastest saloon car available, with a top speed of over 175&nbsp;mph (280&nbsp;km/h)
*The 1991 [[Dodge Spirit R/T]] with a version of the 2.2 L K-car engine with a 16-valve DOHC head designed by Lotus with over {{convert|220|hp|abbr=on}}
* [[Vauxhall VX220]] (badged Opel Speedster outside of the UK) – Lotus produced and based the car upon the same aluminium chassis design as the [[Lotus Elise]]. Production of these models ended in 2005
* Lotus styled and assisted with the engineering of the [[Tesla Roadster (2008)|Tesla Roadster]], an electric sports car based on the Elise, as well as licensing some technologies to [[Tesla Motors]] and constructing the Roadster at their plant in [[Hethel]].<ref>{{cite web |url=http://www.autoblog.com/2006/07/29/done-deal-lotus-will-build-the-tesla-roadster-in-hethel/ |title=Done deal!
