Lamborghini has unveiled the world's most expensive car - a limited edition convertible costing a staggering £3.36 MILLION. The jaw-dropping Lamborghini Veneno Roadster which is based on the Veneno seen in the video above is a limited edition hypercar which goes without a roof. It has been designed by the Italian firm to drive like a race car while being entirely road legal - making it one of the most extreme vehicles ever built. Lamborghini has fitted the Veneno Roadster with a 750bhp V12 engine which gives the topless motor a 0-62mph time of just 2.9 seconds and a top speed of 220mph.
