The Arrows A2 was a radical car in only the team's second year in Formula One. The car was designed to make extensive use of ground effect, even having the engine inclined by 4 degrees, creating a car that is effectively a wing itself.

Just like the Lotus 80 it was designed to run without wings, but it soon appeared that on track the ground effect was less than expected and too variable for the drivers to get comfortable in the car. Arrows quickly realised that and started designing their next car early after its introduction.

The A2 competed in just the last 8 races of 1979, replacing the Arrows A1B. Jochen Mass made it to the finish twice in 6th place, but other than that no points were scored.
