From a technical perspective, the CEPA is a 2.5-liter inline five-cylinder petrol engine featuring direct fuel injection (TFSI), DOHC, and a single turbocharger optimized for rapid boost response. It uses a cast-iron engine block for exceptional strength and thermal stability, paired with an aluminum cylinder head. 

Factory output is approximately 250 kW (340 hp) and 450 Nm of torque, delivering strong low-end torque and thrilling top-end performance. The engine is typically with Audi’s quattro all-wheel-drive system for maximum traction.

Despite its outstanding reputation, the CEPA engine has a few common weaknesses worth noting.

The turbocharger is robust but can suffer from oil-related wear if you extend servicing intervals.

Overall, the Audi RS3 2.5L TFSI CEPA Engine offers a rare blend of durability, unique character, and high-performance capability. When properly maintained and professionally installed, it delivers exceptional longevity and remains one of Audi’s most desirable petrol engines ever produced.
