Zandvoort. DTM In 2007, di Resta switched from single-seaters to race in the Deutsche Tourenwagen Masters (DTM) touring car racing series, for Mercedes. In the championship, he finished 5th overall behind drivers Mattias Ekström (who won his second DTM title), Bruno Spengler, Martin Tomczyk and Jamie Green. Di Resta was the highest driver in the standings to drive a non-2007 car. His performances earned him a 2008 Mercedes C Klasse for the 2008 season, in which he won two races and finished second in the points, four points behind eventual champion Timo Scheider of Audi. In 2009, he finished third overall behind Scheider and compatriot Gary Paffett. In 2010, he won three races in a row on the way to winning the championship.

R. Hildebrand. At the Autosport International show in January 2010, he was said to be close to a deal as the team's test and reserve driver for the 2010 season. The deal was announced on 2 February. Di Resta made his Formula One race meeting début at the 2010 Australian Grand Prix, where he took part in the first free practice session in place of Sutil and finished 11th. He drove in the first practice session of all the following races until the Monaco Grand Prix where he did not take part. He resumed driving for the team at the European Grand Prix and the following British Grand Prix. After sitting out the German Grand Prix he returned for the Hungarian Grand Prix. Di Resta subsequently sat out the Belgian Grand Prix as Tonio Liuzzi and Adrian Sutil needed as much track-time as possible to get the feeling of the new parts. He participated in practice for the Italian Grand Prix, but did not participate in the Singapore or Japanese Grands Prix. The team elected that di Resta should miss the Korean Grand Prix to allow Liuzzi
