The BMW M4 DTM is a DTM touring car constructed by the German car manufacturer BMW. It was developed in 2013 and has been raced in DTM seasons since 2014-present. It was designed by BMW chief engineer Dominic Harlow. The M4 DTM replaced the retired BMW M3 DTM at the end of the 2013 season and based on the production BMW M4.
The first model made its first appearance in the wind tunnel at the BMW Group’s Aero Lab on April 22 – 13 days before the opening race of the 2013 season in Hockenheim. In the summer of 2013, while continuing with aerodynamic testing, the experts in Munich turned their attention to designing new suspension parts. The new components made their first on-track outing in December 2013 – but still within the BMW M3 DTM at that point. The final parts for the chassis of the BMW M4 DTM were in production by the turn of the year, allowing the BMW teams to assemble the first models of the new car in January and February. Three hundred days after the first test in the wind tunnel, the BMW M4 DTM took to the track for its track debut in Monteblanco on February 11, 2014. The production version of the BMW M4 Coupé provided BMW Motorsport with a perfect basis for developing the DTM racing car. Hardly surprising, given the fact that the primary goal of the BMW M GmbH engineers working on the BMW M4 Coupé was to create a robust car suitable for use on the racetrack. Among those to make valuable contributions towards achieving this goal were DTM drivers Bruno Spengler and Timo Glock, who took part in tuning tests at the Nürburgring-Nordschleife. "I am proud to have played my part in the fine-tuning,” said Spengler. “The chassis of the BMW M4 Coupé is very sporty. The feedback from the front axle is extremely direct, and the grip on the rear axle is phenomenal. This car is the ideal basis for our car in the DTM."
The last BMW M car to roll off the assembly line at the main BMW Plant in Munich did so back in 1991. After that, production shifted to BMW Plant Regensburg. Almost 23 years later, the assembly process returned to the main factory – and just a few metres away BMW Motorsport engineers were hard at work tinkering with the racing version of the new car. However, the BMW Plants in Regensburg and Dingolfing were also involved in the development of the BMW M4 DTM. Among other things, the kilometre-long test tracks at the modern production facilities were used for aerodynamic tests. Throughout the development phase, the BMW M4 DTM car was to be seen at what is otherwise the venue for the exhaustive quality control checks performed on all BMW M cars.
