The BRM P126 was a Formula One racing car which raced in the 1968 and 1969 Formula One seasons. It was powered by a 3.0-litre V12 engine. Design was contracted out to former Lotus and Eagle designer Len Terry and the three examples built were constructed by his Transatlantic Automotive Consultants company due to pressure of work at BRM.
The Owen Racing Organisation entered Pedro Rodríguez in the South African Grand Prix, He qualified 10th and retired with a fuel system failure. The team hired Richard Attwood to drive six races. The first event Attwood competed at was Monaco, he qualified sixth and finished second. At the Belgian Grand Prix Attwood qualified 18th and retired with a broken oil pipe. At Holland, he qualified 15th and finished seventh. The French Grand Prix saw the Englishman qualify 12th and finish 7th. At Britain, Attwood qualified 15th and retired with a broken radiator. At the German Grand Prix he qualified 20th and finished 14th. Atwood was replaced by Bobby Unser for the Italian Grand Prix who set a fast time in the early qualifying session. It had been Unser's intention to fly back to the United States for the Hoosier Hundred, at Indiana State Fair grounds, the following day and then return to Milan and race in the Grand Prix. The event organisers announced that if he returned to the United States and race, he would be banned from competing in the Grand Prix, under a ruling which forbade drivers to complete in another event within 24 hours of the start of the Grand Prix. So Unser flew back to the US and did not return. The Owen Racing Organisation thereafter, concentrated their efforts on the BRM P133.
