Porsche upgraded the performance of its 924 with the introduction of a turbocharged model in 1979. While the lower end of the engine remained unchanged, many improvements were made to the upper end of the engine as well as the drivetrain. On the outside, the car gained alloy wheels, a distinctive NACA duct in its hood, and a rear spoiler. Horsepower increased from the naturally aspirated 125 bhp to 170 bhp in the turbo.
