AUDI PB18: THE BACK STORY
AUDI R8 E TRON 2013 This 375bhp all-electric R8 came tantalisingly close to production in 2013. Audi built 10 cars to production standard to test the concept but in the end it was killed by economics and range – each one cost £855,000 to build and at the time battery technology could take it only 133 miles before needing a charge. The project wasn’t a complete waste, though – the extensive use of carbonibre was rolled into later R8s.
AUDI R18 E TRON 2012 2016 The irst hybrid World Endurance Championship racecar, the R18 e-tron won Le Mans in 2012 and Audi took that year’s WEC title. They won in 2013 and ’14 with an e-tron too. A 200kW (268bhp) electric motor powered the front wheels, with a 549bhp 3.7-litre V6 diesel (4.0-litre from 2014) at the rear. After coming second in 2015 and third in ’16, Audi quit endurance racing and moved to Formula E.
