Theodore Racing was a Formula One constructor from Hong Kong founded by real estate magnate and millionaire Teddy Yip. They participated in 51 grands prix, entering a total of 64 cars. In the present day Theodore Racing is an international motor racing team owned by Teddy Yip Jr., competing in the Macau Grand Prix with a Junior Team contesting the Japanese Super FJ Series. Following its last race in 1992, the team made a successful return to racing at the Macau Grand Prix in 2013 under Teddy Yip Jnr, owner of GP3 team Status Grand Prix. Theodore Racing achieved a record seventh Macau GP victory in 2013 with Red Bull Junior driver Alex Lynn. In 2014, the team fielded Estaban Ocon, Nicholas Latifi and Ferarri Academy driver Antonio Fuoco, with an accident preventing Ocon from claiming the win. The team returned to Macau in 2015 with a 3-car entry fielding reigning Macau, and 2015 European FIA F3 Champion, Felix Rosenqvist alongside Formula 3 front-runners Lance Stroll and Jake Dennis. Rosenqvist dominated the event, claiming a record eighth Macau GP victory for Theodore Racing. In the early 1970s, amateur racer Yip met Sid Taylor and agreed to sponsor Vern Schuppan in Formula 5000. This led to Yip backing Schuppan in Formula One with Ensign in 1974. There followed further involvement in America with Schuppan and then support of Alan Jones in the US F5000 series in 1976. In Australia, Schuppan won the Rothmans International Series for Yip driving a Lola T332-Chevrolet in 1976. That year Yip established Theodore Racing. It was run by Taylor and entered an Ensign for Patrick Tambay in F1. After a difficult year in 1977, Yip commissioned Ron Tauranac to build him an F1 car. The car, called the Theodore TR1, was difficult and Eddie Cheever failed to qualify in both Brazil and Argentina but then Keke Rosberg took over and won the International Trophy at Silverstone in the wet, although he qualified for only one GP in South Africa. The car was abandoned in the mid-season.
