What was the first F1 car to use a wing?

Answer 1

In 1968 Colin Chapman debuted his Lotus 49B, which featured a tall wing much like that of Can Am cars at the time. The wing was eventually banned, but eventually led to the use of wings on all F1 cars.

Answer 2

The first wing, at least as they're used in modern F-1 cars, was used by Ferrari, which attached a small airfoil to the rear of the car just aft of the roll hoop in the 1967 Belgian Grand Prix

Answer 3

Jack Brabham drove a 2-litre streamlined Cooper in the 1955 British GP (Bristol engine) with the engine in the rear.

The Bugatti in 1956 French GP was rear engined.

Lotus first entered rear engined cars in 1960, BRM also.

Ferrari went to rear engined F1 cars in 1961.
