In 2026, Audi will be celebrating half a century since the launch of its five-cylinder engine. From its debut in the Audi 100 in 1976 to the high-performance RS 3 of today, the five-cylinder has become a recognisable part of Audi’s innovation, motorsport success, and incredible sound.


Performance

In 1976, the second-generation Audi 100 introduced a 2.1-litre five-cylinder engine producing 136 PS. Audi engineers needed something more refined and powerful than a four-cylinder, but more compact than a six. The result was a compromise that became a key part of Audi’s “Vorsprung durch Technik” ethos.

By the late 1970s, the five-cylinder had already evolved. Turbocharging arrived in 1979 with the Audi 200 5T. This gave 170 PS and 265 Nm of torque. One year later, the five-cylinder-powered Audi quattro brought rally technology to the road with permanent all-wheel drive and a sound that petrolheads very quickly fell in love with.

Motorsport

The 1980s were when Audi dominated rally stages worldwide, with legends like the Sport quattro and the Group B cars leading the way. In 1984, the road-going Sport quattro hit 306 PS, becoming the most powerful German production car of its time. Rally versions delivered up to 450 PS, helping Audi to win multiple world titles with drivers like Hannu Mikkola and Stig Blomqvist.

It wasn’t all about the rallying world, though. Audi’s five-cylinder also made an impact in U.S. motorsports. The Trans-Am Audi 200 and IMSA GTO were powered by turbocharged five-cylinder engines pushing beyond 500 PS. Around the same time, Walter Röhrl famously conquered Pikes Peak in 1987 in a 598 PS Sport quattro S1.


Evolution and Return

After a hiatus in the late 1990s, Audi brought back the five-cylinder in 2009 with the TT RS. Featuring turbocharging and direct injection, it produced 340 PS and quickly found its way into other performance models like the RS 3 and RS Q3. The current-generation 2.5 TFSI engine debuted in 2016 and now delivers 400 PS and 500 Nm of torque.

Today, the RS 3 can go from 0 – 60mph in 3.8 seconds and, with optional upgrades, reach a top speed of 180mph.

Hand Assembled

Each five-cylinder engine is hand-assembled at Audi’s plant in Győr, Hungary. Covering more than 1,000 square metres, the Bock assembly area is where highly trained technicians build the engine from the ground up, including intricate tasks like crankshaft fitting, cylinder head installation, and turbocharger setup. Final tests, both cold and hot, make sure that every unit meets Audi’s performance standards before making its way to Ingolstadt for installation in the RS 3.

50 Years of the Five Cylinder Engine

Even after fifty years, Audi’s five-cylinder engine continues to perform strongly and looks to be a part of Audi’s future as well as its history.
