The ultimate driving challenge is ahead of drivers from the Porsche Carrera Cup GB as they prepare for the Porsche Carrera World Cup on the Nürburgring Nordschleife (Saturday 25 June).For thousands of enthusiasts, be they racers, track day regulars or one-off visitors, the Nurburgring Nordschleife represents the ultimate driving experience; a glorious and daunting 14.173 miles of twists, turns, dips and crest in the Eifel Mountains in Germany. Names like Bergwerk, the Carousel, Flugplatz, Hatzenbach and Hohe Acht have a place in motorsport folklore as just a few of the many mighty challenges on this epic track. Every day that the circuit is not in use for racing, drivers can turn up and pay a fee to drive around this incredible track; on two or four wheels. Look in any car park in the UK and the chances are that at least one car will be carrying the famous Nurburgring circuit map sticker as a badge of honour. ‘I’ve driven around the Nurburgring’ is a proud claim for tens of thousands of petrol heads.For the drivers in the Carrera Cup GB, simply taking part in a race of this magnitude on the world’s greatest race track will make this a true adventure. For the first time in the championship’s nine-year history, the Carrera Cup GB will travel outside the UK and Ireland to be part of this remarkable event. The trip is as much about the buzz of being part of the event and taking on the Nordschleife as the final result and championship points. For many drivers, racing on the Nordschleife is a life ambition.The Nurburgring and Porsche have been inextricably linked over the decades and the hallowed track remains the final testing ground for new Porsche models; a car that delivers performance and driving pleasure at the Nurburgring is ready for any stretch of road or race track in the world. Less than a month ago, the latest Porsche 911 GT3R Hybrid scored a landmark debut race victory during a four-hour round of the Nürburgring Long Distance Championship.Next weekend, a total of 23 competitors from the Carrera Cup GB and the Porsche 911 GT3 Cup Challenge will contest the Porsche Carrera World Cup, which runs prior to the start of the 39th ADAC 24-hour race. It will run over a distance of six laps of the Nordschleife, approximately 95 miles, and more than 250,000 spectators are expected to watch the race.Extensive coverage of the Porsche Carrera World Cup will be carried through the race weekend on the Porsche Origin website; origin.porsche.com
