The Lamborghini Sesto Elemento ("sixth element") is a high-performance limited edition car produced by the Italian automobile manufacturer Lamborghini, which debuted at the 2010 Paris Motor Show. The Sesto Elemento's name is a reference to the atomic number of carbon, referring to the carbon fibre used in its construction. The Sesto Elemento is equipped with Lamborghini's 6-speed "e-gear" automated manual transmission and an all-wheel-drive system, mated to a 5.2 litre V10 engine borrowed from the Gallardo Superleggera, generating 570 PS (419 kW; 562 hp) and 540 N⋅m (398 lbf⋅ft) of torque. The chassis, body, drive shafts, wheels and suspension components are all made of carbon fibre, reducing the overall weight to 999 kg (2,202 lb), a weight comparable to subcompact cars.[2] The Sesto Elemento was the first car to use forged carbon fibre (in the tub and suspension arms), a new type of carbon composite developed by Lamborghini and Callaway Golf Company.[3]
