In 1996, Lamborghini embarked on an ambitious project, collaborating with France’s SAT to engineer a formidable race variant of the iconic Diablo. This endeavor mirrored the burgeoning GT championship scene, aiming to create a machine akin to the Porsche GT1, grounded in production car DNA yet meticulously honed for the rigors of competitive racing. This marked a significant chapter in the history of the Lamborghini Race Car.
The heart of this beast was a specially crafted 6-Liter engine, achieved through an enlarged stroke, a precursor to the engines later found in the Diablo GT and VT 6.0 production models. Enhanced with a reprogrammed injection system, this powerplant unleashed a staggering 655 Bhp, channeled exclusively to the massive 18-inch rear wheels. This bespoke engine was a testament to Lamborghini’s commitment to performance in their Lamborghini race car project.
Exclusivity defined the Diablo GT1, with merely two units ever brought to life. Chassis number VLA12001 found its home with JLOC in Japan, becoming a stalwart competitor in the Japanese GTC series since 1997. The second, chassis WLA12000, adorned in a vibrant yellow, remained under SAT’s custodianship, proudly displayed at their factory as a symbol of their engineering prowess in crafting this Lamborghini race car.
For the 1998 racing season, the Japanese Diablo GT1 underwent further refinement. Subtle fins were added to the front bumper’s flanks, augmenting downforce. The front hood was redesigned to incorporate air extractors, facilitating airflow through the front-mounted oil cooler. Plexiglas replaced the side windows, now featuring small sliding sections, and three air outlets were carved into the rear window section, showcasing continuous evolution of this Lamborghini race car.

Accessibility for maintenance was ingeniously addressed; the Diablo GT1’s entire rear section was designed for swift removal, granting unhindered access to the formidable V12 engine. To ensure optimal engine cooling, dual air intakes were positioned just behind the roofline, drawing cool air inwards, while specialized outlets integrated into the rear cover facilitated consistent airflow through the engine compartment, even with the bodywork secured. These features highlight the race-focused engineering of this Lamborghini race car.
In conclusion, the Lamborghini Diablo GT1 stands as a rare and potent embodiment of Lamborghini’s foray into GT racing. These two exclusive models represent a unique blend of production car foundation and pure racing pedigree, cementing their place in the annals of Lamborghini race car history.
