The beginning of the era of five-cylinder engines in Audi

In the early 1970s, engineers at Audi received a new assignment to develop a new engine that could meet the best of both worlds. For this new engine, Audi intended to increase performance levels compared to the usual four-cylinder engine at the time without compromising the front of fuel economy.

Given that the six-cylinder engines proved heavier, larger and less fuel-efficient, Audi carved a niche with the invention of the 2.1-liter five-cylinder petrol engine. This 136-horsepower engine debuted in series production in the second generation of the Audi 100 C2 in 1976. Since then, the design of the five-cylinder engine and the famous permanent all-wheel drive system from Audi quattro have been identical in heaven. This combination in the Audi Ur-Quattro helped Finn Hanno Mikkola win the driver’s title in the 1983 World Rally Championship.

While European markets will continue to get the TT RS for some time, 2022 is the last year for the TT RS in the USA. Thus, the legacy of the EA855’s 2.5-liter five-cylinder engine is carried over to the 2022 Audi RS3. The baton is in new hands now, and it will be interesting to see how this beloved and popular engine will fight future emissions standards, which will become more stringent over time.
