The Audi RC8 2.0 TFSI is a prototype four-stroke 2.0-litre single-turbocharged inline-4 gasoline racing engine, developed and produced by Audi Sport GmbH for Deutsche Tourenwagen Masters. The RC8 2.0 TFSI engine is full custom-built but partially borrows the cylinder blocks from Volkswagen-Audi EA888 2.0 R4 16v TSI/TFSI road car engine which had a same displacement. Audi RC8 2.0 TFSI was shakedown on 15 November 2018 and later made public unveil on 20 March 2019 after more engine dyno test.[2] Audi RC8 TFSI is the first-ever turbocharged DTM engine to date, replacing the aging Audi DTM V8 engine after nineteen-years of service which conform the "Class 1" regulations that shared with Japanese Super GT under Nippon Race Engine (NRE) formula.
The RC8 2.0 TFSI engine also featuring push-to-pass system which produces 30 hp (22 kW) later 60 hp (45 kW) for more overtaking manoeuvre improvement.[3]
