Efficiency drives in the Alps and the USA (2008)
Audi used the 2008 European Soccer Championships in Austria and Switzerland as an opportunity to stage a comparison drive in which eleven A4 2.0 TDI models participated. The route covered around 1,650 km (1,025 miles) from Vienna to Basel and back again. The winners completed the distance on one 65-liter tank of diesel (17.17 US gallons) and an average consumption of 3.32 liters/100 km (70.85 US mpg). Likewise, all 23 Audi cars participating in the “Mileage Marathon,” which took place in the USA in fall 2008, demonstrated their excellent efficiency.
