It IS possible - Lamborghini Sesto Elemento with less than 1000 kg

Lamborghini presents the Sesto Elemento, a concept car, in Paris. It's sort of a next version Gallardo, built with (probably expensive) lightweight materials. The result though is staggering: 990 kg, 570 hp, 0-100 km/h in 2.5 seconds. Well my key take away: Even with a heavy drivetrain and big engine you can get the weight of the car below 1'000 kg. So with more sensibility (smaller engine, only rear wheel drive, etc.) you actually can build a modern car below 800 to 900 kg. So, engineers, go to your drawing boards and build these modern sportscars that take less and driver better!
