The AF101 was the only Formula One car built by Amon Racing, raced in 1974.
The AF101 designation deriving from A for Amon and F for Fowell. Fowell and Tom Boyce designed the car which featured a single central fuel tank, titanium torsion bars and a forward driving position. One unusual (for the time) feature of the AF101 was that the fuel tank was located between the driver's cockpit and the engine. Structurally, it proved to be weak and was not ready for a Formula One appearance until the fourth race of the season, the Spanish Grand Prix. Amon was only able to qualify 23rd, due to brake-disc vibration that became worse with the tyres required for the wet race that followed. Despite cautious driving, a brake shaft finally broke and Amon was forced to retire after 22 laps.
Following further work and testing, Amon returned for the Monaco Grand Prix and qualified twentieth, but due to mechanical problems, he was unable to start the race. Further problems meant Amon was not able to reappear with the AF101 until the German Grand Prix when both Amon and Larry Perkins failed to qualify. Amon did not reappear with the AF101 until the Italian Grand Prix, three races before the end of the season, but this time he was unable to qualify. That signalled the end of both the car and Chris Amon Racing, leaving Amon to close down the team after the race when the money ran out.
