There aren't many companies out there building Le Mans-style prototype racers you can buy. Dauer once offered road-going Porsche 962 models, but it folded over two decades ago. Caterham is still making the SP/300.R despite the collapse of its partner Lola. The recently-revived ATS will gladly hook you up with its Sport 1000 track toy. But the king of them all is Radical.
F1 drivers typically have a shelf life shorter than what you otherwise might call a career. As the constant stream of new, young drivers usurps existing F1 seats, you're left with a wealth of talent available to contest other forms of motorsport. That's how you end up with former grand prix pilots in other series like IndyCar, DTM and even ice racing. Then there's Le Mans.
Nissan doesn't compete in Formula One. It doesn't field a top-tier LMP1 team at Le Mans. It doesn't race in NASCAR, IndyCar or the World Rally Championship. Yet the Japanese automaker doesn't have to stretch all that far to make the association between its brand and racing. It does, after all, offer competition versions of its GT-R and 370Z for use in a number of sportscar racing series around the world. But where it really shines is in the LMP2 category.
