The Ford Focus ST made its debut in the 2009 British Touring Car Championship season, with Arena Motorsport. During its second season, the car ran on liquefied petroleum gas, taking the first BTCC win for a car powered by this fuel at Brands Hatch. In 2011, Arena (also known as Team AON) shifted to the newer Focus Mk3, while Motorbase Performance drove the ST version. Both cars had engines built to the Next Generation Touring Car engine rules. Motorbase continues to compete with the Ford Focus ST.
