The Porsche Carrera GT concept was introduced in 2000 at the Paris motor show. It featured a 5.5 litre V10 developed from scratch for a Lemans prototype project that was later canceled. However, the production model came with a 5.7 litre V10 with 612 horsepower, up from the 558hp that was promised in the concept car, which meant a 0-60 time of 3.5 seconds. With an automated rear wing that deployed at 70mph, and all-round carbon ceramic brakes, the Carrera GT set a new precedent for technology and engineering in the supercar segment.
