The Brabham BT23 was a formula racing car built by Brabham in 1967. [1] [2]

Development

The BT23 was designed as a Formula 2 racing car and most of the vehicles of this type were also used in this racing series. There was also a Tasman version and some BT23s were converted for Formula One by private drivers.

Design

The car was equipped with a tubular chassis in space-frame configuration, while the engine that equipped it was a Ford-Cosworth FVA, a 4-cylinder in-line of 1 600 cm³ capable of delivering a maximum power of 200–220 bhp (150–160 kW), which droves the rear wheels through a F.T.200 Hewland five-speed manual gearbox. The suspension consisted of double wishbones, coaxial coil springs, and a stabilizer bar in the front section and inverted lower wishbones, trailing arms, coil springs, and stabilizer bars in the rear section. The braking system consisted of four disc brakes.

The car had a space frame, which was reinforced by load-bearing plates in the Tasman version. Jochen Rindt dominated the 1967 and 1968 Formula 2 seasons with the BT23 at will. He won nine rounds out of 15 in 1967, but, being an A driver, did not score points for the European Drivers' Championship. [3]

Racing history

Top drivers including Derek Bell, Kurt Ahrens, Piers Courage, Peter Gethin, and Robin Widdows piloted the BT23. In 1969, motorcycle racer Bill Ivy started his Formula 2 career in a BT23. Jochen Rindt found considerable success in it, winning 9 out of the 15 races in 1967.

Thirteen races were held between 7 March and 25 October, with the Drivers' Championship won by Jochen Rindt and the Constructors' title by Lotus. Rindt died four races before the end of the season, but had earned enough World Championship points that no other driver managed to surpass his total by the end of the season. It is the only season to date in which the World Drivers' Championship title had been awarded posthumously. Jacky Ickx driving for Ferrari finished the season strongly, but his low 4th-place finish in the penultimate round ensured that Rindt's title lead would stand. In the end, all of Rindt's 45 points came from his five wins in the season.
