Audi efficiency marathon over with best of 70.9mpg and 88g/km CO₂

A group of 22 drivers has completed the second stage of Audi's efficiency marathon run between Basel, Switzerland and Vienna, Austria. While the winning team in the first round managed a "mere" 68.4mpg (U.S.) in a 120hp Audi A4 TDI, the top team in the second round managed an even thriftier 70.85mpg (U.S.). That equates to the same 88g/km CO₂ emissions as the tiny Smart ForTwo CDi. Over the 22-hour course of the journey the winning team averaged 46.35mph and if they had continued until the tank was dry they could have covered over 1,242 miles. Five of the eleven teams in the second round achieved better than 68.18mpg (U.S.) and even the most "lead-footed" drivers got 67.2mpg (U.S.). With an official combined rating of 46.12mpg (U.S.) for the A4, the 44 drivers on the two stages of this event demonstrated again that driver behavior can significantly influence, the efficiency of a vehicle. The Audi press release is after the jump.
