The five-cylinder is 50 this year, and Audi Tradition put a show on it. “1-2-4-5-3: 50 years of Audi five-cylinder engines” is at the Audi museum mobile in Ingolstadt through February 28, 2027. Curator Stefan Felber gathered seven engines and fourteen cars, from the 1976 Audi 100 5E to today’s RS 3, with a TT RS, RS2 Avant, and customer-racing TT in the mix.
That firing order is the whole personality. Adjacent cylinders and far-apart ones take turns at 144 degrees of crankshaft rotation. It started as a packaging workaround (a six would not fit the 100) and became the quattro rally soundtrack, then the RS2, then the TT RS. The first 2.1-liter five in the 100 5E made 100 kW. The last Group B rally versions were over 500 PS. In 1989 the IMSA GTO five made 720 PS.
The engine now lives in a tight corner: the RS 3, plus Cupra’s Formentor VZ5. CEO Gernot Döllner has already questioned whether EU7, which takes effect in November, is worth the investment on a low-volume motor. Audi Sport boss Rolf Michl told Autocar in August that evaluations are still running. “We’re well aware about the historical meaning of the five-cylinder,” he said. “It’s so characteristic and also deeply rooted in history — so let’s see.”
No decision yet. Hybridization is one path, spreading the engine across more MQB cars is another. For now, if you want the sound, Ingolstadt is showing the history, and the RS 3 is still the affordable way into the RS lineup. Michl’s line on that is simple: emotion starts in the compact segment.
