Former F1 driver Heikki Kovalainenn has completed his first DTM test after joining BMW foe a private outing at the EuroSpeedway Lausitz.

With the manufacturer gearing up for the final three rounds of the season, where Marco Wittmann is odds-on favourite to seal the 2014 DTM title, Kovalainen was invited to trial the firm's successful M4.

The first time the Finn has driven a DTM car, Kovalainen - who started 111 F1 races between 2007 and 2013 and was a race winner in the 2008 Hungarian GP -, he was impressed with the characteristics of the machine.

"First of all I am grateful that BMW Motorsport offered me the opportunity to drive its car. I was really looking forward to this interesting experience. To be honest, I didn't really know what to expect as I have never driven a car like this. But I felt really comfortable in the BMW M4 DTM from the very beginning.

"It's an impressive car. Of course, it is heavier than a Formula One car and has less power, but the aerodynamics are very good and you can drive through corners very fast. The team helped me a lot to get used to everything. You can see that it is highly professional. I enjoyed the day very much."
