[1] The 01 was the first car built by the British team to participate in the 1983 Formula One world championship.

Designed by Dave Kelly, the car was equipped with a 530-hp Ford Cosworth DFY V8 powertrain with 390 N⋅m (290 lb⋅ft) of torque, which drove the rear wheels through a five-speed Hewland FGA manual gearbox.

The suspension consisted of double wishbones and shock absorbers with coil springs.

[2] With constant driver changes Eliseo Salazar, Jean-Louis Schlesser, Jacques Villeneuve, Sr., and Kenny Acheson, the team only managed to qualify twice, in the first and last races of the season.

The 01 was also used for the first two races of the 1984 season, fitted with a Hart 1.5 litre turbocharged engine.
