Susie Wolff will spend a seventh straight year in the DTM this season after confirming she will stay with Mercedes.
The 29-year-old Briton will remain with Persson Motorsport and will, for the first time in her DTM career, drive current-spec machinery thanks to the series' switch to an all-new set of technical regulations.
Wolff, who competed as Susie Stoddart before her marriage to Williams F1 shareholder Toto Wolff last October, believes the new rules will allow a more even playing field this year.
"Since making my DTM debut in 2006, I have always felt at home in the Mercedes-Benz family, so I am delighted that the relationship continues into 2012," she said. "I'm really motivated and I have been working hard all winter to prepare myself physically and mentally for what is bound to be a very close and competitive season; with the introduction of new cars and regulations, the playing field is going to be more level for all of the drivers.
"We now have three premium manufacturers lined up against each other – Audi, BMW and Mercedes-Benz – which promises to make the battle all the more intriguing and exciting."
Mercedes motorsport vice president Norbert Haug said that Wolff, whose best DTM season came in 2010, when she finished 13th in the points, said that re-signing her was an easy decision.
"Susie has set her sights very high for 2012 and cannot wait to get out there and achieve good results," he said. "I have often admired her speed in races, and there is not a single DTM driver or DTM champion around who has not had to contend with Susie's fighting spirit on the racetrack. Provided she can secure a good position on the grid in our new-generation DTM C-Class Coupe, and get off the line well, then Susie will be even more of a force to be reckoned with in 2012."
