Lamborghini Diablo VT 6.0
The Lamborghini Diablo is the car that bridged two eras at Sant'Agata Bolognese. It succeeded the legendary Countach and preceded the Volkswagen-era Murciélago, making it the last Lamborghini supercar developed entirely under Italian independent ownership (though Chrysler was involved from 1987, and Audi/VW took over in 1998).
Designed originally by Marcello Gandini, the Diablo's styling was controversially softened by Chrysler's design team after their investment in Lamborghini. Gandini reportedly disowned the final result, though the Diablo is still dramatically beautiful — low, wide (2,040mm), and aggressive, with Lamborghini's signature scissor doors.
The V12 engine grew throughout the Diablo's life: 5.7 liters and 485 hp in the original, 5.7L/530 hp in the VT (Viscous Traction, with AWD), and finally 6.0L/550 hp in the VT 6.0 (1999-2001). The VT 6.0 is considered the ultimate Diablo — it benefited from Audi's involvement with improved build quality, the full 6.0-liter engine, and variable valve timing.
The Diablo was the last Lamborghini with no electronic driver aids. No traction control, no stability control, no ABS (until late models) — just 550 hp, four driven wheels, and the driver's skill. It was wild, uncompromising, and occasionally terrifying. The driving experience was raw in a way that modern supercars simply cannot replicate.
Special editions proliferated: the SE30 (celebrating 30 years), SV (Super Veloce, rear-wheel drive), GT (racing homologation), and GTR (race car). The Diablo competed in one-make racing series and at Le Mans. Total production was approximately 2,903 units.
The Diablo requires commitment. The V12 is robust but service costs are high — expect $5,000-10,000 for annual maintenance. The AWD VT/VT 6.0 models are the most usable; the RWD SV is the most exciting. Check for: engine oil leaks (common), clutch wear (expensive — engine must be dropped), electrical gremlins (especially pre-Audi cars), and pop-up headlight motor failure. Build quality improved significantly after Audi's involvement (1998+). The VT 6.0 and SE30 are the most collectible variants.
Total Diablo production: approximately 2,903 units (1990-2001). Key variants: Diablo (1990-94, 485 hp), VT (1993-99, AWD, 530 hp), SE30 (1994, 150 units, 525 hp), SV (1995-99, RWD, 530 hp), VT 6.0 (1999-2001, 550 hp), GT (1999, racing homologation). Chrysler owned Lamborghini 1987-1994, then Mega Tech (Malaysian), then Audi/VW from 1998. The VT 6.0 benefited most from Audi quality control.
