The BMW M3 DTM is a DTM touring car constructed by the German car manufacturer BMW. It was developed in 2010 and has been raced in DTM seasons since their return to the sport after 20 years absence in 2012 until the end of 2013 season before it was succeeded by BMW M4 DTM. It was designed by BMW chief engineer Dominic Harlow. The M3 DTM was based on E92 production car.
BMW began development, design and construction of the BMW M3 DTM in October 2010 alongside the announcement of BMW return to DTM for 2012 season. The first chassis was assembled in mid-2011, with the first vehicle completed in late 2011.
The BMW P66 engine in the BMW M3 DTM generates approx. 480 bhp with the air restrictor specified in the technical regulations. BMW began development, design and construction of the NA V8 engine in November 2010. The first NA V8 engine was assembled in June 2011, with the first engine completed in late-August. Codenamed P66 it was intended to see its first race in the 2012 DTM season. It is made up of 800 different components, consisting of 3,900 individual parts. When designing the DTM drivetrain, BMW Motorsport took full advantage of the technological know-how within the BMW Group. The high-tech foundry connected to BMW Plant Landshut accounts for the large cast parts, such as the cylinder head and crankcase – just as it does in the production of the six-cylinder in-line engine for the BMW M4 Coupé. The cast parts are coated and given the necessary heat treatment within the appropriate departments in Munich. The BMW V8 for the DTM is both a sprinter and a marathon runner. It allows the BMW M3 DTM to accelerate from 0 to 100 km/h in about three seconds. Only ten engines are permitted for all eight BMWs over the course of the entire season. Therefore, reliability is a prerequisite to success.
The engine’s power is transferred via a sequential six-speed sport gearbox, which is operated pneumatically using shift paddles mounted on the steering wheel. The gearbox is one of the standard components, which are used by all the DTM manufacturers. It has 11 final drive ratios, which allow the engineers and drivers to react to the respective circuit and engine characteristics when setting the car up.
With the homologation of the M3 DTM completed on March 1, 2012, the car's race debut was at the 2012 Hockenheimring DTM round on April 29, 2012.
As of 2017, BMW M3 DTM scored 10 victories, 9 poles, 7 fastest laps, 2 constructor title and 1 driver titles (courtesy of Bruno Spengler in 2012).
