BMW Motorsport has already submitted necessary documents for the aerodynamic homologation of the 2014-spec DTM cars to the Deutsche Motor Sport Bund (DMSB). After months of development work on the BMW M4 DTM, it was no longer possible to make modifications to fundamental areas, and it is now primed for a new phase of preparations for the start of the DTM season in Hockenheim, Germany in May 4.
The upcoming tests will mainly focus on optimizing detailed aspects of the package as well as on understanding how to fully use the full potential of the BMW M4 DTM. The BMW M4 DTM is based on the production version of the BMW M4 Coupé.
When stationary, the design’s contours highlight the performance of the two BMW M brothers. The BMW M4 DTM stands out as a BMW M vehicle thanks to its characteristic design elements like the modern twin headlight arrangement and unique twin-bar kidney grille as well as the power dome on the bonnet.
The proportions typical of the BMW M4 Coupé, like the long bonnet, long wheel base, set-back greenhouse and a short front overhang all served as foundations for the low and aerodynamic silhouette of the DTM vehicle. The BMW M4 DTM is powered by a P66 engine that provides up to 480 bhp with the air restrictor specified in the technical regulations.
The engine is composed of 800 different components and 3,900 individual parts. During the design process of the DTM drivetrain, BMW Motorsport benefitted largely from the technological know-how within the BMW Group.
The foundry connected to BMW Plant Landshut in Germany contributed the large cast parts like the cylinder head and crankcase. The cast parts were coated and provided the needed heat treatment. The BMW V8 allows the BMW M4 DTM to accelerate from zero to 100 km/hour in about three seconds.
