GR51
The Gould GR51 refined the concept of the GR37. The chassis, whilst based on a Ralt carbon fibre tub, was further customised for its application in hill climbing. The chassis was mated to a DTM-derived Opel-Cosworth V8 engine enlarged to 2.8 litres from the original 2.5 litres and mated to an Arrows F1 gearbox. Whilst down on absolute power compared to the 4-litre V8 monsters of its competitors, the compactness and light weight of the car, engine and gearbox gave the GR51 a greater power-to-weight ratio, which resulted in a car perfectly suited to the tortuously twisty hillclimbs of the British Championship. With Scottish father-and-son duo of Graeme Wight and Graeme Wight Jr. campaigning the car, Wight Jr. sealed two consecutive championships at the wheel of the GR51 in 2001 and 2002.
