ROAL Motorsport and Team Engstler have both been busy testing at the Vallelunga circuit in Italy this week.

The test allowed the teams to try out the new 1.6 litre engine that they will race in the 2011 World Touring Car Championship.

They were joined at the test by Augusto Farfus, who was driving a BMW Motorsport-run BMW 320 TC. The Brazilian was helping with the development of the new engine, which has been built by BMW Motorsport for the use of its customer teams in the WTCC. Farfus completed 143 laps (nearly 590 km) without any technical problems.

ROAL tested on Tuesday and Wednesday with driver Tom Coronel behind the wheel of its BMW 320 TC. Team Engstler ran two cars over three days for Franz Engstler and Kristian Poulsen, as well as Hong Kong racer Marchy Lee. Lee is set to race a BMW 320 TC this season for KK Motorsport China.
