The McLaren M23 was a Formula 1 car used by the McLaren team between 1973 and 1978. It was one of the most successful cars in the history of Formula 1 and was driven by drivers such as Denny Hulme, Emerson Fittipaldi, and James Hunt. Hunt won the world championship in 1976 with this car.
The M23 was an evolution of the M16, which debuted in 1972. The car was built around a steel tube frame, with an aluminum monocoque that protected the driver. The suspension was independent, with coil springs and telescopic dampers. The car was powered by a 3.0-liter V8 Ford Cosworth DFV engine, which produced about 490 horsepower.
The M23 was one of the first Formula 1 cars to use a hydraulic clutch and a longitudinally mounted gearbox. The chassis was made of thin steel tubes, while the bodywork was made of fiberglass. This made the car relatively lightweight but also vulnerable in a collision.
The design of the M23 was so successful that it served as the basis for the M26, which debuted in 1977 and was further developed. Overall, the M23 contributed to McLaren’s success in the 1970s and contributed to the development of the modern Formula 1 car.
This F1 car:
Two show cars were built by McLaren on behalf of Marlboro at the time. This one ended up on the wall in a bar in Stockholm after faithful service for promotional work. The car is made of a steel chassis combined with aluminium and the body is fibreglass. Back then, there was no carbon fibre used to build F1 cars.
