The Audi TT RS coupe offers an unusual reason to choose a compact performance car: the engine’s configuration is part of the attraction. Five cylinders give it a recognizable rhythm, but the 8S-generation model also deserves attention for the material changes beneath that familiar soundtrack.
Audi’s September 2016 engineering account describes a redesigned 2.5-liter turbocharged engine. The manufacturer put its weight reduction against the predecessor at approximately 57 pounds. An aluminum crankcase accounted for about 40 pounds of that saving. This was substantial work on the engine itself, alongside the styling changes buyers can see immediately.
Where the weight disappeared matters
The engine is a concentrated mass in the car’s front section. Removing material there helps explain why the development story reaches beyond a horsepower comparison. Audi specifically connected the redesign to overall weight and axle-load distribution.
For a buyer, that encourages a broader test-drive question: does the whole car respond in the way you enjoy? Pay attention to the relationship between steering input, body movement and throttle response on a familiar, legal route. A louder exhaust can make an example seem more dramatic without telling you whether its chassis and powertrain suit your driving.
The engineering account also describes a hollow-bored crankshaft and friction-reduction measures. These details belong to the factory development history. They should not be read as a promise about the condition, maintenance cost or remaining life of a particular used engine.

Keep the market and model year straight
The green coupe pictured here is the refreshed 2019 TT RS shown in New York. Audi of America’s April 2019 announcement, distributed through Motor Sports Newswire, gives the US car 394 hp and 354 lb-ft, paired with a seven-speed S tronic transmission and quattro all-wheel drive.
That US release is the appropriate reference for those figures. International material uses different horsepower conventions, and older US TT RS specifications belong to another generation. Keeping a single market and model year on your comparison sheet prevents a surprisingly easy research mistake.
The 2019 update also brought revised front and rear styling. Build the shortlist around the engine generation and equipment you want, then compare cars within that group. A lower asking price is less informative when the listing’s mechanical identity remains vague.
Hear the character at ordinary speeds
Audi identifies the firing order as 1-2-4-5-3. Its five-cylinder retrospective traces the configuration’s return in the earlier TT RS and subsequent redevelopment. That history gives the engine a clear identity beyond its maximum output.
Use a normal road drive to decide how much of that character you want in daily life. Listen at steady cruising speed, during gentle acceleration and when the transmission shifts. Include a passenger if conversation matters on your longer journeys. A brief burst of sound outside the car cannot establish what the cabin will feel like over an afternoon.
For modified examples, ask for a precise list of engine software, intake and exhaust changes before evaluating the drive. Choose whether your goal is a factory-reference car or a documented modified one; the inspection brief should follow that decision.
The 8S TT RS is interesting because its unusual engine configuration survived a serious engineering update. Buy with that complete character in mind, including the quieter, everyday moments between the occasions when the five-cylinder takes center stage.
