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 massively-powerful BMW M12/13 turbocharged inline-four engine. Unlike the BMWs used by the Brabham and Benetton teams whose engines were maintained and updated regularly by BMW, the Arrows engines were maintained by Swiss engine guru Heini Mader and were rated as the least powerful of the BMW runners.

The A9 was supposed to replace the ageing A8 car, but it turned out to be worse than its predecessor. The new car was the team's first carbon composite chassis, built by British Aerospace but delays in manufacture caused the car to be late. Its lack of performance caused Dave Wass to quit Arrows. [1]

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 teammate Christian Danner raced the A9 but retired after 7 laps with rear suspension failure.

The Arrows team found that the rear end was the major problem with the A9 and for a couple of races it was run with its new front end joined to the rear end of the A8. While this actually improved the performance of the new car, Arrows soon returned to running the older A8 for the balance of the season. [2]

Arrows finished the season in 10th place, with a single point, earned by Boutsen's teammate Christian Danner in Austria while driving the A8.

<span class="mw-page-title-main">BMW in Formula One</span> Formula One activities of BMW

BMW has been involved in Formula One in a number of capacities since the inauguration of the World Drivers' Championship in 1950. The company entered occasional races in the 1950s and 1960s, before building the BMW M12/13 inline-four turbocharged engine in the 1980s. This engine was the result of a deal between BMW and Brabham, which resulted in the team's chassis being powered by BMW engines from 1982 until 1987, a period in which Nelson Piquet won the 1983 championship driving a Brabham BT52-BMW. BMW also supplied the M12/13 on a customer basis to the ATS, Arrows, Benetton and Ligier teams during this period, with various degrees of success. In 1988, Brabham temporarily withdrew from the sport and BMW withdrew its official backing from the engines, which were still used by the Arrows team under the Megatron badge. Turbocharged engines were banned by the revised Formula One Technical Regulations for 1989, rendering the M12/13 obsolete.
