An Audi A6 2.0-litre TDI Ultra sedan driven by motoring journalist Andrew Frankel and racing driver Rebecca Jackson along a carefully planned route from Netherlands to Hungary via Belgium, Luxembourg, France, Switzerland, Lichtenstein, Austria, Germany, Italy, Slovenia, Croatia, Bosnia and Serbia.
The pair drove almost non-stop for 28 hours, covering a total distance of 1158.9 miles (1,854.5 km) on a full tank of diesel. The fuel sipping sedan managed to return an impressive fuel efficiency of 75.9 mpg (26.7 kmpl) which is more than official figure of 67 mpg (23.61 kmpl). Average speed during the trip stood at 50 mph (around 80 kmph).
Audi says that despite a careful planning, the drivers were forced to make two unplanned detours into heavy traffic and mountain roads due to an accident and tunnel work respectively. The record run stands testament to A6 2.0-litre TDI Ultra’s outstandingly frugal nature.
Audi A6 2.0-litre TDI Ultra develops a healthy 190 PS yet has a low CO2 emission of 109 g/km. The engine is mated either to a 7-speed S-Tronic twin-clutch automatic transmission or a 6-speed manual unit. A6 2.0-litre TDI Ultra is not all about fuel efficiency as it can accelerate from rest to ton in just 8.2 seconds.
