TESLA MODEL S RUNS A LONG-DISTANCE RACE ON THE 'GREEN HELL' OF THE NÜRBURGRING
“We were alone with the Model S among 140 internal combustion engine cars, fitted with roll cages, wide track tires,” said Uwe. “The other teams were really interested in our experiment. They asked us a lot of questions. We didn't expect so many positive reactions.”
Crashes and breakdowns are so frequent during these public rallies that all cars are required to have towing brackets fitted, so that tow trucks can quickly remove disabled vehicles from the track. “On the Model S there’s no easy way to attach these rings, so we fastened straps to the chassis,” Uwe explains. “For that we have to thank Black Falcon Racing, a well-respected long-distance racing team.”
As every Formula E fan knows, the limited range of an EV adds a new dimension to racing. “There is lot of discussion about Model S on racetracks, mostly focused on the short time performance. But we would like to know what will happen on a distance of more than 250 km on a very hilly and difficult racetrack,” explains Dr. Uwe Koenzen. “The special challenge with a Tesla is to drive fast and efficiently.”
Now, for those of us driving our EVs around town, driving fast and driving efficiently are seen as mutually exclusive - you can zip around and have fun, or you can carefully “hypermile” and maximize your range. A race driver, however, must learn to do both at the same time.
The two German engineers rose to the challenge. “We did a very accurate calculation which takes into account the complex topography of the Ring. We finished with only 5 km of power left in the battery - our calculations and driving matched perfectly.”
Roland and Uwe achieved an average efficiency of 268 Wh/km, which translates in gas-mileage terms to approximately 3 liters per 100 km (about 78 MPGe for US readers). “That is surely an efficiency record,” says Uwe. “Sedans in the same weight class use around 12-15 liters/100 km for these lap times.” Their top speed on the downhill stretches was about 190 km/h (118 mph).
