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 1,600 cc (98 cu in) 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.
