Arrows A9

The Arrows A9 was a Formula One car that the Arrows team used in the 1986 season, powered by the BMW M12/13 turbocharged inline-four engine. It was meant to replace the ageing A8 and was the team's first carbon composite chassis, built by British Aerospace, but delays in manufacture made it late and it proved worse than its predecessor. Its lack of performance helped to make Dave Wass quit the team. The A9 raced only three times, in the hands of Thierry Boutsen at the German and Austrian Grands Prix and Christian Danner in Hungary, and each time it retired. For a couple of races it ran with its new front end joined to the A8 rear, which helped, before Arrows went back to the A8.
