Back in 1996, Lamborghini contacted Signes Advanced Technology (SAT) in France and asking them to design and build a Diablo to compete in GT championships race. Lamborghini had developed a custom 6-liter V12 engine with larger stroke with massive 655 horsepower output on its rear wheels.
The car also has new 18-inch OZ-Racing wheels with racing slicks tires made by Dunlop. The entire suspension and chassis for this car were fully modified by SAT to comply with the racing regulation.
The car still slightly has the same design with a standard Diablo since SAT had heavily redesigned the car. The car now fitted with a carbon fiber body with brand new parts including its front bumper which has a very deep front chin spoiler. The car also has wider fenders and new side skirts which help the airflow from the front section.
The rear section of this car now could be removed easily. It now has an adjustable rear wing in order for them to find the right settings. This car also received two air intakes behind its roof section.
There are only two models developed by SAT and Lamborghini which make it is a rare Diablo. The project was abandoned when they unable to get support from Chrysler for the GT1 idea.
