Stebro was a Canadian constructor of Formula Junior racing cars. The team also competed in one Formula One race, the 1963 United States Grand Prix, where their one car finished in seventh place. Peter Broeker, the owner and president of a firm of automotive accessory manufacturers, designed and built the Stebros in his Montreal plant, to promote the company in the Canadian market. A Stebro Formula Junior chassis, fitted with an enlarged Ford 105E engine appeared in one Formula One Grand Prix, the 1963 United States Grand Prix. The engine, including a Hewland gearbox, was the only alteration, with the Weber Ford 1,500 c.c. engine developing . The car was driven by Broeker and, against the more powerful Formula One cars of the day, finished in seventh place, completing 88 of the 110 laps. Broeker's Stebro later won the all-formula sprint at the Indian Summer Trophy races at Mosport on September 4, 1965. Around 1959, Peter Broeker had introduced the Stebro brand of performance exhaust systems for imported cars. Initially, these were imported from Italy through an association with Frank Reisner (who was in the initial stages of creating Intermeccanica). Broeker quickly set up a plant to fabricate these exhaust systems in Pointe Claire, Quebec, and eventually moved to eastern Ontario. After ending the race program, Stebro remained a manufacturer of performance exhaust systems for European and American cars until some point after Broeker's death in 1980. Two decades later, the Stebro name and jigs were eventually purchased by a Swiss mechanic called Andy Petschenig; he reintroduced the Stebro brand, now featuring stainless steel and concentrating at first on Italian automobile applications. Their products were developed and manufactured from a factory near Ottawa, Ontario, Canada. Problems with delivery hurt their reputation and the new Stebro went out of business in 2013. Motor racing Peter Broeker moved to Canada with his family at the end of World War II. He opened an automotive repair business in Hamilton, Ontario, moving to Montreal later in the fifties, where he opened the Stebro Garage. Though a fan of racing, it was not until his move to Montreal that he became serious with the sport, especially single seat formula car racing. Soon he was supply the racing world with customized exhaust systems to improve performance, and later would become a race car constructor. The Stebro Mark 1, the first of Stebro, was built in 1960
