Back in 1999, Lamborghini enthusiasts were in for a pleasant surprise when the Diablo GT made its debut at the Geneva Motor Show. This vehicle was a game-changer that combined the modifications of the GT2 race car with the boldness of the Diablo, resulting in an exceptional road racing performance that left a lasting impression. In fact, it remains as the fastest road-worthy Diablo ever produced by the factory, with a top speed of 215 mph (346 kph) achieved upon delivery in September of that year.
One of the most remarkable things about the GT was its comprehensive list of upgrades, which included a larger V12 engine and a radical carbon fiber body. As a result, the GT was lighter, faster, and had better road-handling than all the other Diablos that came before it.
The GT's weight reduction was largely due to its extensive use of composite materials, with the bodywork made almost entirely of carbon fiber. Only the steel roof and aluminum doors were non-composite panels.
One of the most noticeable features of the GT was its front bodywork, which had a wider track, brake cooling ducts, and a front-mounted oil cooler. Air flowed into the oil cooler from the very front of the car and exited through an extractor on top of the bonnet. A large engine scoop also sat on the engine cover, supplying the V12 with fresh air. What set it apart from the SV was that the airflow for this scoop was dynamically controlled by the car's onboard computer, making it even more unique.
