Mini E Race – Click above for high-res image gallery

The 13-mile long Nürburgring Nordschleife is one of the most treacherous race tracks in the world, even on the best of days. Taking it on in the fog seems like a recipe for disaster. Nonetheless, that's exactly what a BMW engineering team did recently with a very special edition of the Mini E. The team took one of the battery-powered Mini models and applies some weight reduction measures to the body and then installed the usual array of racing bits. The latter included new tires, brakes and a roll-cage.

The electric powertrain underwent some recalibration, likely to tone down the overly aggressive regenerative braking before ex-DTM race driver Thomas Jäger took to the 'Ring. Jäger managed to set a reasonably respectable lap time of 9 minutes, 51.45 seconds with a maximum speed of 116.2 miles per hour. No word from BMW on how much juice remained in the battery at the end of the lap. Check out a highlight real of the lap after the jump.

PRESS RELEASE

Green power through the Green Hell.

Munich/Nürburg. Taking on the infamous Nürburgring-Nordschleife circuit at race speed with an electrically powered car is an ambitious project, but the BMW Group has just become the first car manufacturer to make it happen. Today the MINI E Race, a modified race-spec version of the standard MINI E, completed a lap of the legendary 20.8 km "Green Hell" in a time of 09:51.45 minutes. The MINI E Race hit a top speed of 187 km/h.

"The length and profile of the Nordschleife place extreme demands on the technology of our electric car. But the MINI E Race met this considerable challenge with great authority," said the BMW Group's Peter Krams, who headed up the project. "The aim of this unique undertaking was to provide an impressive showcase of the great potential of the MINI E and its environment-friendly drive concept."

At the wheel of the electric racer for the hot lap was former DTM racing driver Thomas Jäger from Munich. "I've driven this circuit many times, but never in such an extraordinary car," said Jäger, the MINI Challenge champion in 2006. "The power of the electric motor has an incredible effect, as you can access its full reserves of torque at all times. Another element of this fascinating experience is the lack of noise from the drivetrain. All in all, that was certainly the cleanest and quietest race lap I've ever driven."

Extensive preparations had to be completed before the car could roll out onto the Nürburgring-Nordschleife. The MINI E Race was fitted with a special lightweight body and a roll cage in order to ensure optimum performance and safety on the track. And various other components, such as the suspension, brakes and tyres, are also race specification. Other than that, however, the car relies almost exclusively on the standard technical make-up of the MINI E. For example, it shares the same 150 kW/204 hp electric motor, supplied with energy from 5,088 lithium-ion battery cells. The control electronics and the software were reprogrammed to achieve an optimal driving performance for the Nordschleife. The power from the emission-free motor is channelled to the front wheels via a single-stage helical gearbox with a lengthened gear ratio.

      These "weight reduction measures" should be applied to the entire Mini line.

        Haha, at least make it an option.

        ...like plastic side windows? Call me spoiled but I'll stick with glass. :)

      I wonder exactly how much juice was left when the finished? What do they do about pit stops? I read a web-comic the other day that talked about electric car racing, pretty funny

      Can there ever be a Electric racing league, will you have enough charge to drive home after a day at the track? These are all questions for the future people.

        Uhmm, replace the battery much?
        • 4 Years Ago
        pure electrics make zero sense for racing

        You would need a trailer to haul your car and a separate trailer to haul your batteries.

      Highlight "reel".

      Brownie points for BMW Engineers; it's projects like these that push creative and kinetic bounds among engineers and help them strive to implement these technologies throughout their model lineup, one step at a time.
