Astra RNR2
The Astra RNR2 is a Group 6 sports prototype race car, designed, developed and built by British amateur racing driver, Roger Nathan, in 1969. Only two models were produced.[1][2] It debuted at an R.A.C. race at Snetterton, in 1970; being driven by Roger Nathan. It achieved moderate success in sports car racing, winning 4 races (plus 1 additional class win), scoring 6 podium finishes, and clinching 2 pole positions. It was powered by a naturally-aspirated 1.8 L (110 cu in) Ford-FVC four-cylinder engine, producing 245 hp (183 kW).[3] This gave it a power-to-weight ratio of exactly 0.45 hp/kg, or 1 hp/lb.[4][5][6][7][8][9]
