The Alfa Romeo 164 ProCar was one of the most unusual racing experiments of the late 1980s. Although it looked like a modified version of the road-going Alfa Romeo 164 sedan, the car was actually a full racing prototype built for a proposed ProCar championship that aimed to combine production car silhouettes with Formula 1-level technology. Beneath the body sat a carbon-composite monocoque chassis developed with input from Brabham and Dallara, along with push-rod suspension and other hardware normally found in single-seaters. Power came from Alfa Romeo’s 3.5-liter naturally aspirated V10 known as the Tipo 1035, an engine originally created for the brand’s Formula 1 program. Mounted in a mid-engine layout behind the driver, it produced around 600 horsepower and revved past 12,000 rpm while pushing a car that weighed roughly 750 kg. The ProCar series never materialized, leaving the project as a rare prototype that briefly appeared during the 1988 Italian Grand Prix weekend at Autodromo Nazionale Monza, where it was demonstrated by Formula 1 driver Riccardo Patrese.
