Lamborghini’s Aventador J is designed, above all else, for going fast. There’s no climate control or navigation system, and in place of a roof and windshield are small wind deflectors. The idea is essentially a two-seater sport-bike: they’ve used carbon fiber across the bumpers, air scoop and more. Under the hood is the same 700-hp 6.5-liter 12-cylinder found in the standard Lamborghini Aventador, meaning you’re flying. Yes, this is a real car you can buy.
