    Mercedes DTM driver David Coulthard explains the differences between the 2011 and 2012 Mercedes DTM race cars

    The Mercedes DTM cars in 2012 have been very, very fast. It is rumored they are making the most horsepower but power is not the only change from 2011. The 2012 season is incredibly competitive with BMW entering the fray so Mercedes looked at several things to make sure they would be at their absolutely best and in compliance with updates regulations. Coulthard first hits on the most obvious and one of the most important which is the tires.

    The new tires are 2 inches wider for 2012 than 2011 and they are also heavier due to this. The added weight is a factor especially on a race car where every additional gram is scrutinized. It is also tougher on pit crews who have to deal with a 10% heavier tire and wider/heavier wheel.

    The aerodynamics are changed as well. The arches need to be flared to accommodate the new rubber which obviously changes the surface area and drag. The rear wing is also different and much larger but standardized in the effort of controlling costs.

    Check out the video below for all the changes and details. Coulthard does a very good job explaining the aerodynamics, wheels, safety, and reasoning for the changes.

    That was a cool video, I miss watching Coulthard race in F1. I didn't realize he was still racing in DTM.
