The 1984 Pontiac Fiero is among the most unique cars ever to pace the Indy 500. It is the only mid-engine car ever to pace the 500, as well as the shortest car to ever hold the honor. It is also the second time a 4-cylinder car would pace at Indy. 

However, the engine in the Fiero pace car was far different from the 92-horsepower version found in the production model Fiero. This bored out 2.7L engine produced 232 horses and turned a lap at better than 136 MPH. The car also featured an air intake located
above the roof to help cool the mid-engine car.

2000 pace car replicas were made available by Pontiac and were powered by a 2.5L 4-cylinder 92hp engine.
