On June 23, eleven Audi A4 2.0 TDI models began an efficiency competition organized by Audi and Auto Bild magazine. To stand a chance of winning, the teams had to complete the distance of 1025 miles with an average fuel consumption of more than 58.8mpg US.
The Audi A4 with the new two-liter TDI engine with 120hp output provides ideal conditions for fuel-efficient driving: With a combined consumption figure of 46.12 mpg and CO2 emissions of only 215.65 grams per mile, the efficiency of the midsize sedan is outstanding.
Participants in the Audi efficiency competition must do significantly better even these impressive combined consumption figures. After all, as in any contest, all that matters is the result - in this case, the lowest fuel consumption.
Utmost concentration, anticipation and careful use of the gas pedal were called for; furthermore, a very economical driving style would allow the Audi A4 TDI to take full advantage of its talent for saving fuel.
Both rounds of the efficiency marathon ran between Basel and Vienna and back. The route is 1025.26 miles and passes through Switzerland, Germany and Austria. For the most part it uses freeways, but also on highways and through towns and cities - and must be covered on a single tank of fuel. The Audi A4 has a fuel capacity of 65 liters, meaning that an average fuel consumption of under four liters (over 58.8mpg) is required. Incidentally, CO2 emissions in this case are approximately 160.93 g/mile - further proof of the excellent fuel-saving of TDI technology.
This was an ambitious goal in regular traffic, but was possible with the Audi A4 TDI. Additional fuel consumption gauges were installed in the vehicles so drivers could see the current fuel status at any time. However, what ultimately counted was how much diesel was left in the tank at the finish.
The first lap was driven from June 23 to 25 from Basel to Vienna and back, upon which the victory ceremony takes place. The second round of the efficiency marathon begins on June 27 in Vienna and runs to Basel and back to Vienna, where the winners of the second round are honored.With its outstanding consumption figures -57.37 mpg for the extra-urban cycle, 35.11 mpg for the urban cycle and 46.12 mpg combined - the new basic TDI unit in the Audi A4 demonstrates the advances made by Audi's efficiency strategy.
Its output of 120hp and maximum torque of 214 lb-ft provide impressive performance; top speed is 127mph. At the same time, the two-liter TDI combined with six-speed manual transmission and common rail injection system is notable for its refined running and ride comfort.We will bring you the results from this competition when they are released.
