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 (420 PS; 414 bhp), later 340 kW (462 PS; 456 bhp), 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.[2][3][4]

Audi TT-R DTM

The Audi TT-R DTM uses a 4.0 L (244 cu in) 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 (339 kW; 461 PS) @ 6,800 rpm and a maximum torque of about 510 N⋅m (376 lbf⋅ft) @ 6,000 rpm, while using two 28 mm (1.1 in) air intake restrictors.[5]

Audi A4 DTM

The Audi A4 DTM is powered by a 4.0 L (244 cu in) 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 (343 kW; 466 PS) and a maximum torque of more than 500 N⋅m (369 lbf⋅ft).[6][7][8]

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 (343 kW) and coupled to a 6-speed transmission grafted from the previous A4 DTM car, while using a Bosch MS 5.1 ECU.[9][10][11][12][13][14][15][16]

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 (373 kW; 507 PS) and torque of over 500 N⋅m (369 lbf⋅ft). 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.[17][18][19][20][21][22]
