The Arrows A9 was a Formula One car which the Arrows team used to compete in the 1986 Formula One season. It was powered by the BMW M12 Tubocharged engine.
The A9 was supposed to replace the ageing A8 car, but it turned out the be worse than its predecessor.
Because of this the team stuck with the A8 from the previous season. As a result, the A9 only saw action at three races, at the German and Austrian Grands Prix, in the hands of Thierry Boutsen, in both of these races the car failed to finish after its turbocharger failed.
At the Hungarian Grand Prix team mate Christian Danner raced the A9 but retired after 7 laps with rear suspension failure.
Arrows finished the season in 10th place, with a single point, earned by Boutsen's team-mate Christian Danner in Austria while driving the A8.
