The Lamborghini Sesto Elemento ("Sixth Element" in English) is a two-door, two-seater, V10 high-performance lightweight limited edition car produced by Italian automaker Lamborghini, which debuted at the 2010 Paris Motor Show. The Sesto Elemento's name is a reference to the atomic number of carbon, in recognition of the car's extensive use of carbon fiber.

The Sesto Elemento is equipped with a 6-speed semi-automatic transmission with paddle shift and all wheel drive system, mated to a 5.2 litre V10 engine borrowed from the Gallardo, generating 578 PS (425 kW; 570 hp) and 540 N·m (400 lbf·ft) of torque. The chassis, body, drive shaft and suspension components are made of carbon fiber, reducing the overall weight to a mere 999 kilograms (2,202 lb), a weight comparable to subcompact cars.

Air is released through 10 distinctive hexagonal holes in the engine cover, while two intakes funnel cool air into the mid-mounted engine compartment. Lamborghini claims a 0–100 km/h (0–62 mph) acceleration time of just 2.5 seconds,and top speed of over 210 mph. Lamborghini sources said that "...they will sell it in very small numbers, in 2013."

Lamborghini Sesto Elemento has a power to weight ratio of 1.75 kg (3.86 lb) per horsepower, which is currently the best power to weight ratio of a production Lamborghini.

The Sesto Elemento's interior is generally bare with few vehicle comforts such as air-conditioning and car stereo. The seats are made of foam and stuck onto the chassis of the vehicle, reducing weight and production costs.
