Just a few weeks ago, BMW Sauber driver Nick Heidfeld took his F1.07 racecar into a snow covered horse race track in St. Moritz, Switzerland. Now BMW is planning their next demonstration at the Nurburgring's legendary Nordschleife track April 28th as a "thank you" to fans. BMW will use the event to promote all of its' Motorsports teams as well as the BMW Driver Training program, BMW Adventure World, "Ring Taxi" rides and the Performance Center which are all based in Nurburgring. The Formula One press conference for the German Grand Prix will also be held. One of the highlights of the event, besides Heidfeld's F1.07 circuit run, will be BMW's works drivers giving passengers "fun laps" around the circuit in an M5, a BMW 320si WTCC and Z4 M Coupe. Host to Formula One races 31 years ago, the Nordschleife track is still considered one of the most challenging race circuits in the world and remains open to the public. Anyone familiar with our spy photos section, knows the popularity of the difficult driving Nordschleife circuit with car makers testing their latest models.
