This touring car was created by the Bavarian manufacturer for competition in the "Deutsche Tourenwagen Masters" (DTM). It was developed in the 13th year for seasons 14 through 18, replacing the M3 DTM, and later succeeded by the turbocharged "BMW M4 Turbo DTM." After homologation, completed in March of the 14th year, the debut of this car took place on May 4th at the first DTM race of the same year at the "Hockenheimring" track, where Marco Wittmann from the "BMW Team RMG" secured its first victory.
Development: Entering the aerodynamics laboratory of the "BMW Group" about 13 days before the start of the 13th season, specialists from Munich actively continued testing the aerodynamic components, initiating the development of entirely new suspension components. These newly created elements first appeared on the racetrack in early December, but at that time, they were still being used in the M3 DTM chassis. Production of modified M4 components began at the end of December 2013, allowing the engineering team to build the first few models of the new racing car in January of the 14th year. The BMW M4 DTM delighted fans with its debut on the track in Montebello on February 11th, 300 days after the initial aerodynamic test.
Aerodynamics: Diligent work on the DTM modification of the car was conducted by the engineers of "BMW Motorsport" simultaneously at three factories: in Munich, Regensburg, and Dingolfing. Throughout the development process, factory 1-kilometer test tracks were utilized for aerodynamic testing.
The production "BMW M4" and "DTM BMW M4" have an incredibly low ground clearance. The aggressive design elements emphasize the power of these "siblings" even in a static state. Attractive details such as twin headlights and the characteristic Bavarian double kidney grille guaranteed the M4 increased attention among fans of the "M" series.
The side mirrors of the M4 DTM with a two-post mount were additionally modified from an aerodynamic standpoint for the race track, ensuring an efficient airflow at the rear of the car. Considering that the aerodynamic component of modern race cars plays a crucial role in DTM, the engineers at "BMW Motorsport" dedicated a significant amount of man-hours to aerodynamic performance characteristics and airflow dynamics. Similarly to the production version, the front of the racing version was equipped with air curtains designed to reduce resistance. Narrowed air ducts directing flows past the wheels, thereby removing turbulent loads from the wheel arches, accelerate the airflow passing through the front skirt. Another feature is the flat rear window optimizing airflow directed towards the rear wing, and the plate installed along the side air duct gave the car much more expressive features. Proportions characteristic of the production M4 coupe—extended wheelbase, long hood, lowered ride height with a short front overhang—make the M4 DTM incredibly fast even when standing still.
Curb: Weight Another component of high efficiency on the race track is the low center of mass and low weight. The racing version of the M4, along with the driver, weighs only 1110 kg. This is 80 kg less than the previous model. These indicators positively impacted acceleration and fuel consumption dynamics. This result was achieved through the widespread use of lightweight materials: aluminum and carbon fiber. Almost 100% of the body of the BMW M4 DTM is constructed from durable yet extremely lightweight carbon fiber.
Engine: The racing version is equipped with the existing "P66 V8" engine, previously used by its predecessor, the M3 DTM. The "BMW P66" engine in the M4, with an air restrictor (in compliance with technical regulations), delivers 480 horsepower. It comprises around 800 components assembled from 3900 parts. The V8 for DTM racing, combining speed and reliability, serves as both a marathoner and a sprinter simultaneously. This combination propels the M4 DTM from 0 to 100 km/h in 3 seconds, and its high level of reliability (considering restrictions on the use of new engines) became a prerequisite for success.
