Stebro

'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 110 hp (82 kW). 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.

After ending the race program, Stebro remained a manufacturer of stainless steel performance exhaust systems for European and American cars until recently. Their products were developed and manufactured from the factory in Ottawa, Canada.

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 in the Stebro repair garage on McGill street in Montreal. It had a front engine formula junior design powered by a BMC engine and drive train. The second evolution of the Stebro was the Mark II, a mid-engine design also powered by BMC. The Mark III was a modified Sadler MKV sports racer. The Sadler was modified by adding eight inches to the wheelbase and fitted with a conventional transaxle.
