If the Super Veloce version was already a race-ready car, the Diablo GT pushed its limits even further. Its design was based on a prototype called GT1, which was specially developed for endurance racing but never raced. This rear-wheel drive model had an all-carbon chassis with an aluminium roof. Aerodynamic modifications included a new front bumper design and a large bonnet air intake already adopted on the SE 30 Jota, and a modified air extraction profile under the floor of the car. The interior was particularly well treated, with leather and alcantara upholstery with carbon fibre inserts, a smaller diameter sports steering wheel and racing seats with 4-point seat belts. Air conditioning and a GPS system with a large screen on the centre console coupled with a camera positioned under the rear bumper completed the equipment package.
