When the 2018 German Touring Car Championship Series (DTM) opens at Hockenheim in May, the M4 DTM and its competitors from Audi and Mercedes will be running a new aerodynamic package that reduces downforce by about 1/3. BMW has released graphic renderings of its 2018 M4 DTM that provide side-by-side comparisons with the 2017 version of the car. The most substantial changes are visible on the side of the car, where the side channel has been simplified, the side plate has been removed, and the number of “aero flicks” has been reduced to one. There have also been alterations to the front skirt and the rear of the car. The details are apparent in the graphics shown here.
In addition to the changes in the aero package, an element has been dropped from the front axle of the new car, leaving one conventional side spring per wheel.

longer in the turns before they can put their foot down again.”
BMW Motorsport has also released a photo of the 2018 car in the new M livery that will appear on Marco Wittmann’s car in the March 2-3 DTM test sessions on the Vallelunga circuit in Italy. Wittmann, Timo Glock, and Augusto Farfus will once again drive for BMW Team RMG in 2018, while Bruno Spengler will return to BMW Team RBM along with DTM newcomers Philipp Eng and Joel Eriksson.
