In 1988, Alfa Romeo produced the 164 Pro-Car featuring a mid-engine layout and powered by a 3.5-litre V10 engine. This unusual powerplant was originally planned to be used by the Ligier F1 team and produced 620 hp. Weighing only 1,653 lbs., the 164 Pro-Car was good for 211 mph and went quarter of a mile in only 9.7 seconds. It was planned to race in a special racing series, as a support event to Formula One Grands Prix. With Alfa Romeo being the only manufacturer to produce a car for this series, the project was ultimately cancelled.
