• Efficiency challenge between Wittmann and Spengler in the electric and emission-free BMW i3 (REX).
  • The route to the fourth DTM race weekend of the season stretches from Garching, near Munich, to Nuremberg.
  • Spengler: “It was special to just drive as efficiently as possible.”

Munich. The two BMW DTM drivers Marco Wittmann (GER) and Bruno Spengler(CAN) competed in a very special “pre-race race” on Thursday. The DTM champions from 2012 (Spengler), 2014 and 2016 (Wittmann) took on an efficiency challenge in two BMW i3s* as they travelled from Garching, near Munich (GER), to the Norisring (GER). 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.
