BMW M4 DTM - Bavarian force in DTM championship
The BMW M4 DTM is a successor of the BMW M3 model which had been competing in the DTM until 2013. After passing all necessary tests, the new BMW car has had immediate success winning its maiden race in the championship at Hockenheim and titles in Drivers and Teams championships, beating fierce rivals Mercedes and Audi.
Important role of special materials
The BMW M4 DTM is 4.775mm long, 1.950mm wide and 1.200mm high. This model lies low and flat on the tarmac and has characteristic design elements, such as a modern take on the twin headlight arrangement and a distinctive twin-bar kidney grill which ensures that the car clearly stands out as a BMW M vehicle.
Role of aerodynamics
As aerodynamics play a very important role in the DTM, the engineers clearly put a lot of their knowledge into issues such as aerodynamic drag and air flow to ensure the best possible performance on the track. The results of BMW M4 DTM are quite impressive. The lightweight construction has been achieved by the usage of special materials as carbon-fibre, aluminium and reinforced plastic. Almost the entire body of the car is made of light materials so the total weight of the BMW M4 DTM, with a pilot, is around 1.200 kilograms.
The monocoque concept sets the benchmark in the terms of safety in motorsport. With an integrated tank, steel roll cage and additional parts, it ensures an effective protection of the driver in case of crashing and provides a unique driving experience.
The BMW P66 V8 is a four-litre naturally aspirated engine which generates approximately 480 bhp with the air restrictor specified in the technical regulations. It has four valves per cylinder, 2 x 28.0 mm air restrictors (in accordance with regulations). This BMW engine could be described as both a sprinter and a distance runner.
Power in this BMW is transferred with a sequential six-speed gearbox which is operated pneumatically using shift paddles mounted on the steering wheel.
BMW M4 DTM’s suspension has a double wishbone axle with pushrods and adjustable shock absorbers with six springs. Stopping power is provided by a hydraulic braking system featuring ventilated brake discs and lightweight calipers.
After success in the debut DTM season, BMW released limited BMW M4 DTM Champions edition of only 23 cars, celebrating the number of the champion Marco Wittmann’s car.

Three seasons, three trophies for BMW M4
BMW M4 DTM was the championship winning car in 2015, leaving Audi and Mercedes behind, and was a winning car in the Drivers’ championship year earlier, bringing home two trophies in two years. as of the end of 2016, BMW M4 recorded total of 14 race victories in DTM, denying the words of Mercedes driver Gary Paffett who described BMW M4 as boring.
In 2016, BMW M4 won another DTM title when Marco Wittman triumphed in the Drivers’ Championship, scoring three race wins on his way to the title. In 2017, modified and developed BMW M4 again will be used in DTM series.
