New FIA rules required the car to be adapted for a new 1.6 turbocharged engine with 310 PS (228 kW / 306 bhp) and 335 Nm (247 lb-ft) of torque.

Chevrolet has debuted the new 2011 WTCC Chevy Cruze, now ready to taken on another season after its victorious run last year.

Chevrolet won both the Drivers' and Manufacturers' crowns in the 2010 WTCC with the Cruze. Now, it has unveiled the 2011 spec version as per the new FIA rules.

The new technical rules are meant to reflect the reality of today's smaller, more efficient, turbocharged power plants. So WTCC has switched from naturally aspirated 2.0 liter engines to turbocharged 1.6 liter units.

The 2011 WTCC Chevy Cruze now comes with a 1.6 turbocharged power plant with an output of 310 PS (228 kW / 306 bhp) and 335 Nm (247 lb-ft) of torque. In order to adapt the car to the new power plant, many design changes had to be made to the car, including redesigns for the cooling and ancillary engine systems, front suspension, brakes, aerodynamics and weight distribution.

The driver lineup remains the same, though, with world champion Yvan Muller resuming his duties in the number 1 car with colleague Rob Huff in number 2. Huff will also be writing a column on the 2011 WTCC season for the British paper The Sun. Chevrolet will also have a third and fourth car for the season.

The 2011 WTCC Chevrolet Cruze will makes its debut next weekend in Brazil at the Curitiba race.
