A provisional list of teams and drivers was revealed on 23 February, and the official entry list was published on 4 March.
Team and driver changes Chevrolet retained their three full-time drivers from
2010,
Yvan Muller,
Robert Huff and
Alain Menu.
Cacá Bueno also joined the team in a fourth car at his home meeting in Curitiba. The team utilized the newly introduced engine. Again, two further Chevrolets were entered by
bamboo-engineering, who retained their
2010 drivers,
Darryl O'Young and
Yukinori Taniguchi. Bamboo campaigned Lacettis at the first round in Curitiba, but contested the rest of the season with Cruzes.
SUNRED Engineering again ran six cars through three different team guises.
Gabriele Tarquini remained with the team and was joined by former
SEAT León Eurocup racer
Aleksei Dudukalo, who brought
Lukoil sponsorship into the team. Another three-car outfit was headed by
Tiago Monteiro, who was joined by
Michel Nykjær, and another graduate from the SEAT León Eurocup,
Pepe Oriola.
Fredy Barth completed the SEAT sextet, with his SEAT Swiss Racing by SUNRED team. The SEATs began the season using a two-litre turbo diesel engine and from Hungary introduced a similar engine to that used in the Chevrolets. However, the cars were branded as SR Leon with no
SEAT support at all. Leaving the team is
Jordi Gené, who parted with the team before the end of the 2010 season.
Norbert Michelisz remained in the championship with the
Zengő Dension Team, but switched to a BMW 320 TC, having campaigned a SEAT in 2010, winning a race at Macau. He began his campaign at the second round of the season at Zolder. Three other teams campaigned a single 320 TC during the season;
ROAL Motorsport returned to the series, with
Tom Coronel switching from a SUNRED SEAT,
Wiechers-Sport ran Urs Sonderegger – another driver from the SEAT León Eurocup – at the European races held during the season, and DeTeam KK Motorsport ran
Marchy Lee, who steps up from the Asian Porsche Carrera Cup. The factory
BMW Team RBM did not return in 2011, and drivers
Augusto Farfus and
Andy Priaulx moved into sportscar racing, entering the
Intercontinental Le Mans Cup. Independent BMWs were however campaigned by the
Proteam Racing and
Liqui Moly Team Engstler outfits. Proteam ran three BMWs; two 320 TCs for
Mehdi Bennani, who moves from Wiechers-Sport and former single-seater racer
Javier Villa, as well as a naturally aspirated 320si for
Fabio Fabiani. Bennani and Villa replaced Independents' champion
Sergio Hernández and
Stefano D'Aste. Team Engstler ran two cars once again, with
Franz Engstler being joined by
Kristian Poulsen, who drove for his own team in 2010 after driving for Engstler in
2009. Poulsen replaced
Andrei Romanov.
Polestar Racing campaigned a Volvo full-time in 2011, having contested five meetings over the past four seasons.
Swedish Touring Car Championship runner-up
Robert Dahlgren again campaigned the car as he had done in each of Polestar's events to date. The team also introduced a similar engine in the mid-season. ==Calendar==
