Both racing drivers were aiming to use as little energy as possible
on the way to the fourth DTM race weekend of the season, driving the
two cars.
The route first took Wittmann and Spengler along
minor roads from Garching to Ingolstadt (GER). They then continued the
journey to Nuremberg (GER) on the motorway. Wittmann arrived at the
Dutzendteich with a range of 133 kilometres remaining, while
Spengler’s on-board computer still showed 121 kilometres. Victory in
the efficiency challenge therefore went to the BMW Team RMG driver.
“Challenging Bruno with the BMW i3 was great fun,” said
Wittmann, who will enjoy home advantage at the Norisring. “We stayed
in the slipstream of the lorries on the motorway to save as much
energy as possible. We made it easily – and now we are looking forward
to racing at the weekend.”
“It was rather unusual for us as racing drivers to be driving as
efficiently as possible, instead of as fast as possible,” said
Spengler. “But the challenge was great fun. The BMW i3 is an excellent
car and the remaining range shows that longer journeys are no problem
at all.” The BMW i3 has a battery capacity of 94 ampere hours, greatly
increasing the range when compared to the previous model.
This coming weekend, Wittmann and Spengler will leave the BMW i3
and return to the cockpits of their BMW M4 DTMs at the Norisring. The
seventh and eighth DTM races of the season then will be all about pure performance.
