Audi may reconsider the fate of its iconic 2.5 TFSI engine, which was previously slated for discontinuation due to stricter Euro 7 regulations. The company is now exploring a hybridization option.

Audi Sport chief Rolf Michl stated that the brand is open to various approaches for preserving the engine, including electrification. This could allow the powerplant to meet new environmental standards and remain on the market after 2027.

The engine in question is a 2.5-liter inline-five turbocharged unit (EA855 series) that has become a signature feature of RS 3 models and some Cupra variants. It has won numerous awards and is widely regarded as one of the most charismatic engines in the industry. The current version features an aluminum block, dual injection, and an advanced thermal management system.

One potential solution is a plug-in hybrid (PHEV) setup, which would reduce emissions but add weight and cost to vehicles. This presents a challenge, especially for already expensive models like the Audi RS 3.

If Audi succeeds in adapting the engine to meet new regulations, it would represent a rare case of preserving a classic internal combustion engine during the electrification era. Otherwise, the RS 3 and similar models may fully transition to hybrid or electric powertrains.

Audi is attempting to balance emotional appeal with environmental responsibility. The fate of the 2.5 TFSI will demonstrate how long automakers can maintain legendary engines in this new reality.
