HIGH FIVE
• The first Audi to feature the five-cylinder engine was the 1005E in 1977. Back then, the 2.1-litre engine produced 100kW.
• In 1980 the Quattro debuted and was powered by a five-cylinder turbocharged, intercooled engine with 147kW and packaged for both road use and motorsport. This was followed by the Sport Quattro that was the basis of the Group B rally car and its newly developed four-valve light-alloy engine delivered 225kW.
• After leaving the WRC Audi had a crack at the Pikes Peak hill-climb which it won with Walter Röhrl at the wheel of the Sport Quattro S1 E2 that had 440kW on tap.
• Having tasted success stateside Audi lined up for the IMSA-GTO with its five-cylinder engine now smashing out a substantial 530kW.
• During the mid-1990s, the V6 replaced the five-cylinder engines until 2009 when it made a comeback in the turbocharged and direct-injected 2.5-litre powered TTRS that boasted 250kW, then 265kW in the model update of 2013.
