One car was built, and it was designed around a modified version of Porsche's 3.5-litre V10 engine that was originally designed for Formula 1 in 1992. The project was cancelled before the car was built, leading to various rumours about the reason for its demise. ==Design and development== In 1998 Porsche designed a Le Mans Prototype for the following season, assigning it the codename 9R3. It was initially to use a modified version of the turbocharged flat-six engine found in the Porsche 911 road car, but, although the design was completed in November 1998, Porsche opted against building the car. Due to the inherent flaws of using the heavy flat-six and the extra cooling the engine would've needed, Porsche instead redeveloped the 3.5-litre V10 engine that was originally developed in 1992 for Formula One; it was redesigned for both 5-litre and 5.5-litre capacities, and the pneumatic valve springs were removed, as the air restrictors mandated under LMP regulations made them redundant. The chassis was unaltered apart from suspension geometry for newer tyres and the engine mountings to accommodate the new engine. In May 1999 the project was halted, but the chassis was completed and underwent a two-day private test, driven by Allan McNish and Bob Wollek who reportedly gave positive feedback.〔 Despite Porsche's initial denial of the 9R3's existence rumours circulated about its cancellation including: the engineers were diverted to the Porsche Cayenne SUV project;〔 to avoid competing with its Audi R8 stablemate which won the 2000 24 Hours of Le Mans;〔 insufficient competition after the withdrawal of BMW, Toyota, Nissan and Mercedes-Benz. The engine from the car was used in the Porsche Carrera GT concept car and was detuned for the production version.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Porsche LMP2000」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
