The Judd GV 4 Litre V10 made its race debut in 1999, powering the Rafanelli Riley & Scott LMP1 sportscar to victory in its second race of the American Le Mans Series at Road Atlanta.

Over the next 6 years the engine became the benchmark for LMP1 customer engines, providing the best combination of performance, weight, fuel efficiency and reliability. The engine powered the Doran racing team’s Dallara to victory at the Daytona 24 hours in 2002, finishing 5th & 6th overall at LeMans in the same year with the Oreca team’s Dallaras. Further victories in races and championships on both sides of the Atlantic followed until the engine was superceded by the GV 5 litre in 2004.

The engine can now be found powering many late model Formula 1 cars, such as Benettons, Arrows or Tyrrells where the original engine is no longer available or cost effective to rebuild. The enviable record the GV 4 established in sports car racing has continued in the single seater market. For example, all races in the 2010 BossGP championship were won by Judd GV 4 powered cars. The GV4 produces up to 750hp in unrestricted form.
