Lamborghini Sesto Elemento

Lamborghini Sesto Elemento, probably the most expensive cars on the planet, with prices reaching  £ 1.77 million, equivalent to almost US $2.8 million but unfortunately the car was not allowed to drive on the streets.

The Sesto Elemento's name stems from the car's extensive use of carbon fiber, carbon being the sixth element in the periodic table of elements. Unfortunately, with a body made ​​of carbon fiber, the car was considered too light for driving on public streets. As a result, according to The Sun, the Italian manufacturer's cars can only be used in circuit race.

According to wikipidea, The Lamborghini Sesto Elemento (literally "Sixth Element" in Italian) is a two-seater, V10 high-performance concept car produced by Italian automaker Lamborghini, which debuted at the 2010 Paris Motor Show. The Sesto Elemento is equipped with a 6-speed paddle-shift, semi-automatic transmission and all-wheel-drive system, mated to a 5.2-litre V10 engine borrowed from the Lamborghini Gallardo, generating 570 horsepower and 540 Nm (398) ft-lb of torque. The chassis, body, driveshaft and suspension components are made of carbon fiber, reducing the overall weight to a mere 999 kg (2,202 lbs), making it the lightest car Lamborghini has ever produced. Perspired air is released through 10 distinctive hexagonal holes in the engine cover, while two intakes funnel cool air into the mid-mounted engine compartment. 

The Sesto Elemento's high amount of horsepower combined with low overall weight translate to a power-to-weight ratio of 0.57 hp/kg (0.26hp/lb). Lamborghini claims a 0–100 km/h (0-62 mph) acceleration time of just 2.5 seconds, and a top speed in excess of 300 km/h (186 mph). 

Lamborghini sources said "...It will never be road legal". Autoweek Magazine said a "...A stratospheric price tag, perhaps about $2.8 million..." The car is featured in the video game Need for Speed: Hot Pursuit, in the downloadable content (DLC) pack Lamborghini Untamed, alongside the digitalized Lamborghini Countach and Lamborghini Diablo SuperVeloce. 

The plan is only 20 units Sesto Elemento manufactured by Lamborghini. Super luxury car that will be available in the market in October.
