This coming weekend will see the annual 24 Hours of Le Mans take place in France. In total, 62 cars will compete, split into three different classes. At the front of the field are the very fastest hypercars—wickedly fast prototypes that are also all hybrids, with the exception of the V12 Aston Martin Valkyries. In the middle are the pro-am LMP2s, followed by 24 GT3 cars—modified versions of performance cars that include everything from Ford Mustangs to McLaren 720s. It is racing nirvana. But with so many different makes and models of cars in the Hypercar class, some two-wheel drive, others with all-wheel drive, how do they ensure it's a fair race?
Get ready for some acronyms
Sports car racing can be (needlessly) complicated at times. Take the Hypercar class at Le Mans. The 21 cars that will contest it are actually built to two separate rulebooks.
One, called LMH (for Le Mans Hypercar), was written by the organizers of Le Mans and the World Endurance Championship. These prototypes can be hybrids, with the electric motor on the front axle: Ferrari, Peugeot, and Toyota have all taken this route. But they don't have to be; the Aston Martin Valkyrie already had to lose a lot of power to meet the rules, so it just relies on its big V12 to do all the work. Most of the cars are purpose-built for the race, but Aston Martin went the other route and converted a road car for racing.
