Launched in model year 1979, the 924 Turbo closed the performance gap between the 924 and the 911 SC.
The bodyshell of the 924 Turbo was based on that of the 924. At the front, a number of air intakes differentiated it from the basic model:
Vertical air slots in the front apron for air supply to the brakes and the oil cooler
Four air intakes between the headlights and a NACA air intake on the right-hand side of the bonnet to ventilate the engine compartment
A Black rear spoiler was also mounted on the rear lid of the 924 Turbo. The aluminium wheels, with the multi spoke design, were fastened with five wheel nuts instead of four (as was the case with the basic 924).
The 924 Turbo's turbocharged 2.0-litre four-cylinder in-line engine initially produced 170 PS. In model year 1981, the engine's efficiency was improved and the power was increased to 177 PS.
