McLaren, unlike many other constructors, in the 1970 played simultaneously on many fields –the team was involved in Formula 1, IndyCar, CanAm and F5000. In designing the new Formula 1 car for the 1973 season, McLaren make the most out of its multiаfaceted experience. Gordon Coppuck, McLaren chief designer, combined the monocoque of the 1972 Indy 500 winning M16B and the suspension of the M19 F1 racer to create one of the most successful F1 cars ever constructed. A Ford Cosworth DFV engine was used, which was prepared by specialist tuning company Nicholson-McLaren Engines which pushed the DFV output to around 490 bhp. One of the biggest visible differences between Indy M16B and new M23 was the addition of a large airbox to force air into the engine intakes. Danny Hulme and Peter Revson were the main team drivers, with newcomer Jody Scheckter and experienced Jacky Ickx entered as third car drivers in some races. Livered in Yardley colors, the M23 debuted in the 3rd race of the season, in South African Grand Prix. Denny Hulme promptly qualified it on pole and finished 5th in the race. Hulme and Peter Revson took three wins between them that season: Hulme won in Sweden and Revson took the only Grand Prix wins of his career in Britain and Canada. In the 1973 Drivers’ Championship Revson was 5th, and Hulme 6th, while McLaren took the 3rd place in the Constructor’s Championship. The M23 became one of the most long-living and successful F1 car in the F1 history. With various developments it was used for 6 seasons (1973 – 1978) scoring totally 16 victories in World Championship Grand Prix races.
