Back in 1992, Lamborghini presented a roofless Diablo prototype at the Geneva Motor Show. But it took 3 years of development to design the Diablo VT Roadster and its original sliding carbon fibre roof system. On the outside, the Diablo VT Roadster features side vents taken from the Diablo SE30, which feed the rear brake discs and oil coolers. The rear bumper is also very similar to that of the Diablo SE30. The front bumper is also different from that of the Diablo VT coupé. The fog lamps are now separate, with two rectangular and two circular ones, and are complemented by two air intakes on the sides for the brakes. The Lamborghini Diablo VT Roadster also gets twin oval tailpipes instead of the coupé’s round ones. Finally, the 17″ wheels on the Lamborghini Roadster are also special. Inside, the seats are a little different, with special leather capable of resisting water in the event of a surprise downpour.
