The Opel Speedster is a mid-engined, targa-topped, two-seat sports car sold by German automaker Opel and introduced in July 2000. It was built in both RHD and LHD versions at the Lotus Cars plant in Hethel, Norfolk, England. It was presented at the Geneva Motor Show in March 1999 and went into full production the following year. It was sold by Vauxhall as the VX220 in the United Kingdom and shared much in common with the Lotus Elise, although Opel claimed few parts were interchangeable. Design and development Due to changes in European crash safety regulations for the 2000 model year, Lotus needed to replace the original Elise. In October 1999, a deal was made between Lotus and General Motors in order for the former to gain sufficient funds to develop a new Elise. As part of the deal, Lotus agreed to develop and produce the Opel Speedster and Vauxhall VX220 on its new Series 2 Elise chassis. The first Speedster concept car was shown at the 1999 Geneva Motor Show. Whilst the new Elise would use a Toyota ZZ engine, similar to that found in the Toyota Celica, the Speedster was designed to use a GM Ecotec engine from the Opel Astra. Neither engine had been used in the original Elise, which was fitted with a 1.8-litre Rover K-Series engine. In order to accommodate the production of the new cars, Lotus expanded its Hethel factory to a capacity of 10,000 cars, with around 3,500 slots allocated towards the Speedster. Production of the Speedster commenced in March 2001. The Speedster utilized an aluminium frame that weighed only , and bodywork made entirely of fibreglass. The entire car weighed , making it roughly lighter than the similarly sized Toyota MR2. The Speedster's all-aluminium alloy 2.2 L Z22SE engine produced , making the Speedster considerably more powerful than the Series 2 Elise was at launch. Production As an answer to calls for a more powerful version of the Speedster, Opel introduced a new two-litre turbocharged version of the Ecotec engine, which produced , but also weighed slightly more at . In 2004, a limited run of sixty track-focused Speedsters were produced for the United Kingdom. The Vauxhall VXR220 was equipped with larger brakes, upgraded tyres and lowered suspension, and tuned to produce . Other features included further performance-oriented seats and unique Speedline alloy wheels. The wheels were 16 inches at the front
