All American Racers is an American-licensed[2] auto racing team and constructor based in Santa Ana, California.

The Formula One team, based in the United Kingdom and using British-built Weslake engines was named Anglo American Racers.

[4] The team were adjacent to Harry Weslake's engine development plant and half a mile from Elva cars.

The engine had four valves per cylinder at a narrow included angle (thirty degrees) that allowed a single cover to enclose both the close-spaced camshafts on each bank.

During this two-decade period, Bobby Unser, who drove Eagle cars for most of his teams, joined AAR as the sole driver, winning the 1975 Indianapolis 500.

In 1988, the team moved up to the GTP category with two chassis – a modified Toyota 88C Group C car and a team-designed Eagle HF89 purpose-built for IMSA competition.

Powered by a turbocharged 2.1-liter Toyota inline-4 developing up to 800 horsepower and generating 10,000 pounds of downforce at 200 mph, the MkIII won 21 of the 27 races in which it was entered – a record so dominant that it has been blamed for the collapse of the GTP series.

[17][18] AAR created a special Trans-Am Series version of the Plymouth Barracuda, running in the 1970 season with drivers Dan Gurney and Swede Savage.
