Ingolstadt, December 3, 2025 – Audi begins the celebrations marking the 50th anniversary of its legendary five-cylinder engine, one of the brand’s most emblematic features since its debut in the Audi 100 in 1976.
The evolution of this mechanical architecture has profoundly shaped the automaker’s history, both in mass production and in the rally stages that made the concept famous in global motorsport.

An engine that shaped Audi’s identity
The first five-cylinder engine appeared in the Audi 100 5E, with 136 PS, derived from the EA 827 four-cylinder. From there, Audi introduced a sequence of innovations: turbocharging, five-cylinder diesel engines and high-performance units for competition. The pinnacle of recognition arrived in 1980 with the Audi quattro, which set a new standard in the world of rally racing.
Total domination in motorsport
With the Audi quattro, Audi won the World Rally Championship in 1982 and 1983, powered by the 200 PS turbocharged five-cylinder engine. Even more radical versions emerged, including the legendary Sport quattro with 306 PS and the Group B rally car, which reached 450 PS.
The peak came in 1987, when Walter Röhrl won Pikes Peak driving the Sport quattro S1 (E2), equipped with an astonishing 598 PS. In the United States, the engine shone again in competitions such as Trans-Am and IMSA GTO, achieving outputs above 700 PS.
The modern era: the rebirth of the 2.5 TFSI
After a period away from the production lines, the five-cylinder returned in 2009 with the Audi TT RS, ushering in the modern generation of the 2.5 TFSI engine. Today, it reaches its peak in the Audi RS 3, delivering 400 PS and 500 Nm, accelerating from 0 to 100 km/h in 3.8 seconds and reaching 290 km/h with the RS Dynamic Package.
The unmistakable sound
The deep and irregular roar, the result of the 1-2-4-5-3 firing order, has become an Audi trademark. The variable-valve exhaust system expands the acoustic range, especially in RS dynamic modes.
Lightweight, high-precision technology
Built with an aluminum block, dual injection and a 1.5-bar turbocharger, the 2.5 TFSI combines high performance with efficiency. Weighing around 160 kg, it is compact and engineered for rapid response, reinforcing its status as one of today’s most celebrated performance engines.
Hand-built production in Hungary
The five-cylinder engine is hand-assembled at the Győr factory in Hungary, where it goes through 21 stations operated by specialists. After cold and hot testing, the engine is shipped to Ingolstadt to be installed in RS 3 models.
With five decades of history, the five-cylinder engine remains one of Audi’s greatest symbols — uniting tradition, innovation and pure driving emotion.
