German automaker Audi is celebrating the 25th anniversary of the TDI engine with a special version of the RS5 fitted with a diesel engine. Dubbed as Audi RS5 TDI Concept, the model uses a 3.0-litre V6 TDI engine, ditching the current 4.2-litre V8 petrol engine. This is the first time when a RS-spec car has been plonked a diesel engine and the said Concept will be officially presented at AMI (Auto Mobil International) event in Leipzig, Germany.
The 3.0-litre diesel powerplant is capable of producing 385PS of max power and 750Nm of peak torque. The engine comes mated to a twin-clutch 8-Speed automatic gearbox, which sends power to all four wheels through Audi’s Quattro system. The 0 to 100 kmph mark is reached in 4 seconds with a top speed of 280 kmph. This engine features a twin-turbo setup with separate low-pressure and high-pressure turbos connected to a charge air intercooler. There is also a bypass valve to help build boost at lower revs. The RS5 TDI will also be equipped with a sport differential and an active exhaust system with an electronically controlled butterfly valve to change the exhaust note.
For the sake of comparison, the standard Audi RS5 that is fitted with a 4.2-litre V8 petrol engine is rated at 450PS and 430Nm, which is good to propel the car from 0 to 100 kmph in 4.6 seconds with an electronically restricted top speed of 250 kmph.
