Audi: Efficiency marathon ends after 1,650 kilometers
  • Audi A4 2.0 TDI runs on 3.44 liters of diesel per 100 kilometers
  • All eleven Audi A4 2.0 TDI models reach the finish without refueling
  • Fuel consumption between 3.44 and 3.65 liters per 100 km

20 randomly selected readers of a motoring magazine and a team of two from Audi fully exploited the efficiency potential of the new Audi A4 2.0 TDI with an output of 88 kW (120 hp) in order to drive from Basel to Vienna and back on a single tank of fuel. All eleven teams made it to the end and still had between five and nine liters (1.32 and 2.38 US gallons) of diesel left over.

With full concentration from beginning to end and outstanding levels of enthusiasm, the participants in fact managed to surpass the very high expectations. After a total driving time of 22 hours on average with an average speed of between 74 and 81 km/h (45.98 and 50.33 mph), the white Audi A4 cars reached their destination. It thus became clear just what potential there is in the driver’s foot for reducing fuel consumption.

The new two-liter TDI engine provides ideal conditions for economical driving. With a combined consumption figure of just 5.1 liters per 100 kilometers (46.12 US mpg) and CO2 emissions of only 134 grams per kilometer (215.65 g/mile), the efficiency of the sportiest midsize sedan is simply outstanding. At the same time, the A4 is always capable of bringing the impressive dynamism that distinguishes every Audi onto the road.

However, participants in the Audi efficiency competition significantly bettered even these impressive combined consumption figures. The winning team needed just 3.44 liters of diesel fuel per 100 kilometers (68.38 US mpg). This equates to CO2 emissions of only 91 grams per kilometer (146.45 g/mile) – an outstanding figure at an average speed of 81.4 km/h (50.58 mph). Four teams achieved under 3.45 liters (over 68.18 US mpg). But even the Audi in eleventh place recorded an impressive average fuel consumption of 3.65 liters (64.44 US mpg).

To achieve these extremely low figures, the teams had the air conditioning switched off nearly all the time. However, considering the amount of fuel left in the tanks of the eleven Audi A4 cars at the end, it would certainly have been possible to enjoy the comfort of the high-performance, ultra-efficient automatic air conditioning as well.

    There are some excellent things coming out of the VAG TDI efforts and even Porsche will have something soon.
