About this car
Discover the history
The 1977 Osella PA5 was an evolution in Osella’s line of successful sports prototypes, designed primarily for endurance racing and hill climbs. Osella, an Italian constructor founded by Enzo Osella, was renowned for building competitive sports cars and hill climb machines. By the mid-1970s, the company had a solid reputation in sports car racing, particularly in European competitions. The PA5 represented a continuation of Osella’s focus on lightweight, agile prototypes with a powerful yet efficient engine setup.
The Osella PA5 was equipped with a BMW M12 4-cylinder engine, producing around 280 horsepower. This powertrain was common in several competitive sports cars of the time, particularly in the 2-liter class, and helped the PA5 compete effectively in its category. The chassis was designed with a tubular space frame, which provided both rigidity and lightness. This was coupled with an aerodynamic body designed to minimize drag and increase stability at high speeds, making the PA5 well-suited to fast circuits and hill climb events where maneuverability and speed were essential.
In terms of its racing pedigree, the PA5 competed in various endurance racing events and was particularly prominent in the European sports car and hill climb circuits. One of the more notable teams to race the PA5 was Torino Corse, with drivers such as Petitti and Filanino achieving success during the car’s active racing period. The PA5’s combination of a powerful engine and lightweight chassis allowed it to excel in events where agility and power-to-weight ratio were critical, especially in hill climbs where Osella cars traditionally performed well.
Osella’s sports prototypes, including the PA5, played a significant role in the brand’s success outside of Formula One, where the company also competed. The PA5, like its predecessors, was recognized for its engineering excellence and reliability, crucial factors in endurance racing where durability often determined success. Over time, Osella continued to evolve its sports car designs, with the PA series being the foundation for subsequent models, such as the PA6 and PA7, which built on the lessons learned with the PA5.
Today, the Osella PA5 remains a popular car among vintage racing enthusiasts. Its eligibility for prestigious historic racing events such as the Le Mans Classic keeps it relevant, and restored examples often appear in these races, where their historical significance is celebrated. Restored models with rebuilt engines and fresh FIA papers continue to draw interest from collectors and racers alike, with the car’s unique blend of Italian craftsmanship, competitive spirit, and engineering prowess making it a sought-after piece of motorsport history.
The Osella PA5’s contribution to the world of sports car racing, especially in the 2-liter class, ensures its place in the pantheon of successful endurance racers from the 1970s. Its combination of lightweight construction, aerodynamic design, and a reliable BMW engine made it a competitive force on the track and a memorable part of Osella’s storied racing legacy.
