The Lamborghini Diablo SV-R is a lightweight competition version of the SV and the first Lamborghini to be officially built for motorsport purposes, as Ferruccio Lamborghini had never desired to build "street legal race cars" like rival Ferrari. The Diablo SV-R was unveiled at the 1996 Geneva Motor Show.
Rather than comply with the requirements for any established racing series, Lamborghini created its own Lamborghini Supertrophy which ran for four years (replaced later with the GTR Supertrophy for the Diablo GTR), with its inaugural round held as the support race to the 1996 "24 Hours of Le Mans".
The 28 Diablo SV-R's entered, which were built in 4 months on the Diablo assembly line along with production SV's, all finished this first event without significant problems.
Features[]
- The Diablo SV-R featured a stripped-down interior with a rollcage, racing seats, and a removable steering wheel; the power glass side windows were replaced with fixed Plexiglass with traditional race-style sliding sections.
- On the exterior, the electric pop-up headlamps were replaced either with fixed units (similar to those which appeared later on the road cars in 1999) or with air vents for the front brakes.
- A larger, deeper front spoiler was fitted, while the rear bumper was replaced with a diffuser assembly.
- The standard rear wing was also replaced with an adjustable carbon fibre unit.
- Side skirts were added for aerodynamics, but this left so little ground clearance that pneumatic air jacks also had to be installed to raise the car for service in the pit lane.
- Lightweight, hollow center-lock OZ wheels were used, although these were later switched to stronger Speedline units.
- Linear-rate springs were used with Koni shock absorbers and were adjusted to about twice the stiffness of stock Diablo SV suspension.
- The SV-R weighed 1,385 kg (3,053 lb), 191 kg (421 lb) less than the standard SV model.
- Under the engine lid, the standard 5.7 liter V12 engine remained, but was reworked to have a power output of 540 PS (397 kW; 533 hp) and 598 N⋅m (441 lb⋅ft) of torque by means of a revised fuel system and variable valve timing, which would later appear on production Diablos.
- The engine was bolted to a 6-speed manual transmission.
- Each car came with a season's factory support and an entry to the one-make series. All repairs and maintenance were carried out by Lamborghini.
The series' first title winner was BPR regular, Thomas Bscher, who became involved with the business side of the brand in later years. In total, 31 examples of the SV-R were produced.
- Only a few cars have been modified for road use, including one in the United States which received a Diablo VT 6.0 front clip and was painted with the Stars and Stripes.
