Lamborghini Aventador J
Starting with the everyday 700-hp Aventador, Lamborghini taunted the bull even further by removing the roof, adding several aerodynamic panels and generally shucking weight from a car that only had 3,472 lbs. to begin with. Even the seat fabrics have been swapped for something Lamborghini calls "Carbonskin," a fabric made from carbon fibers that's at least a decade away from being used on a teenager's hat. With no windshield, the interior has to get some form of waterproofing; the rear mirror pops up like Wall-E's head from the center of the dash. It and the roll bars behind the driver are the highest points in the car.
