Since it’s initial launch 40 years ago, the second-generation Audi 100 five-cylinder petrol engine has witnessed a number of enhancements and developments, including four-valve technology, turbocharging, rally engines and five-cylinder diesel units.
After multiple discussions around five and six-cylinder in-line engines in the early 1970s, Audi engineers decided to fit the first five-cylinder petrol engine within an Audi 100 (C2) in 1976 – ruling the six-cylinder option unfavourable in terms of weight distribution and installation space.
In fact, delivery of the first Audi 100 5E took place in March 1977 and the five-cylinder has since achieved cult status.
Five-cylinder engines were, however, phased out for an eight year period from 1997 onwards, but in 2009 the automotive industry witnessed a five-cylinder comeback, with the advanced turbocharging and petrol direct injection showcased in the TT RS. Thanks to our renowned quattro technology, the transverse-mounted, 2.5-litre engine was capable of achieving 340PS.
Now, the 40 year strong, five-cylinder powerplant heritage continues through the means of a 2.5 TFSI engine fitted within our newly launched TT RS Coupé and Roadster; with the modern TT RS achieving a staggering 400PS.
