The Audi DTM V8 engine family is a series of prototype, four-stroke, 3.6-liter to 4.0-liter, naturally aspirated V-8 racing engines, developed and produced by Audi for the Deutsche Tourenwagen Meisterschaft, between 1990 and 1992; and later the Deutsche Tourenwagen Masters, between 2000 and 2018.

Audi V8 DTM
Audi developed a Group A competition version of the Audi V8 engine for entry into the Deutsche Tourenwagen Meisterschaft (DTM) (German Touring Car Championship) auto racing series equipped with a 309 kW, later 340 kW, 3.6 V8 engine and 6-speed manual transmission, and began racing with it in 1990 with Schmidt MotorSport (SMS) running the operation, and Hans-Joachim Stuck, Walter Röhrl and Frank Jelinski driving.

Audi TT-R DTM
The Audi TT-R DTM uses a 4.0 L Audi naturally-aspirated V8 engine in partnership with Neil Brown Engineering for development, building, assembly, maintenance and tune-up role, it has a power output of approximately 455 hp @ 6,800 rpm and a maximum torque of about 510 Nm @ 6,000 rpm, while using two 28 mm air intake restrictors.

Audi A4 DTM
The Audi A4 DTM is powered by a 4.0 L Audi naturally-aspirated V8 engine in partnership with Neil Brown Engineering for development, building, assembly, maintenance and tune-up role, it has a power output of approximately 460 hp and a maximum torque of more than 500 Nm.

Audi A5/RS5 DTM
The A5 DTM was still fitted with a V8 engine that used in a previous Audi A4 DTM and Abt-Audi TT DTM were built jointly by Audi and Neil Brown Engineering (NBE) rated at 460 hp and coupled to a 6-speed transmission grafted from the previous A4 DTM car, while using a Bosch MS 5.1 ECU.

After the 2012 season, the vehicle was renamed RS5 DTM, corresponding with the Audi RS5 production model. It is powered by a naturally-aspirated engine and 2x DOHC camshafts. The engine itself is a custom-built Audi 4.0 L V8, with four valves per cylinder, and a 90-degree V-angle. It now has a power output of over 500 hp and torque of over 500 Nm. Front engined and longitudinally mounted engine mounting layout, the RS5's engine is indirect fuel injected. The RS5 DTM's ECU is a Bosch Motronic MS 5.1 and other components such as the CDI ignition are also supplied by Bosch.
