BMW M4 DTM Goes from V8 to Inline-4 Turbo

The BMW M4 DTM, modified to comply with Class 1 regulations and powered by the newly-developed BMW two-litre turbo engine, made its first appearance at BMW Group Plant Dingolfing. With BMW works driver Bruno Spengler (CAN) at the wheel, the car completed its first kilometres with BMW Turbo Power.

The turbo engine is a key component of the new Class 1 regulations, which come into force in the 2019 DTM season.

The previous V8 engines are being replaced by efficient and significantly more powerful four-cylinder turbo engines with two-litre capacity. All the modifications required to fit the new engine, in accordance with Class 1 regulations, have already been made on the BMW M4 DTM.

These include alterations to the air inlets and outlets, as well as the intake and exhaust system. Further evolutionary phases, based on the new regulations, will be implemented before the new car is homologated.

The first ITR test in preparation for the 2019 season is scheduled to take place from 11th to 14th November 2018 at Estoril (POR).
