Group Racing Developments

Group Racing Developments, known more simply as GRD, was a short-lived British constructor of racing cars. It was formed in 1971 with a large percentage of staff coming from those made redundant from the closure of Lotus Cars customer car manufacturing arm. They built cars for Formula 2, Formula 3, Formula Atlantic and Sports 2000 racing classes until a decline in British racing vehicle manufacturing bit into the industry in 1975 that paralleled the oil crisis.^[1]
