Click here to download printer friendly version Arrows' second F1 design was raced in the 1979 season. It was intended to run wingless, as the ground effects underside of the car would produce enough downforce, but it soon appeared with a rear wing. The Ford DFV engine is mounted inclined to the front for ground effects purposes. It was a revolutionary car and worked well on the drawing board but it proved a failure; after its first race work was begun on its successor.
