People love nice round numbers. Why is not entirely clear, but they do. And that’s particularly true when that number heralds an anniversary. So it’s natural that the Automobile Club de l’Ouest (ACO), organizer of the 24 Hours of Le Mans for its entire existence, is making a big deal of this year’s race. It’s the event’s centenary, after all.
Okay, so it’s not the 100th race. There were nine years during and following World War II when no race was held. The 1936 race cancellation was due to the most French of reasons, a labor strike. And there’s that small matter of the event not even being a race until its sixth running in 1928. But forget about all that because what matters—yes, even more than nice round numbers—is that 2023 promises to be one of the best races in years.
That’s almost entirely down to a historic accord announced three years ago between the ACO and IMSA that will now allow the Eurocentric Le Mans Hypercar (LMH) class to run head to-head against the new-for-2023 IMSA-defined Le Mans Daytona hybrid prototypes (LMDh). Both classes put out a maximum 500 kW or 671 hp (measured at the driveshaft). And both varieties of prototype must have a downforce-to-aerodynamic-drag ratio of 4:1.
LMDh cars, like the ones that raced at this year’s 24 Hours of Daytona in IMSA’s GTP class, must be based on one of four possible independently designed chassis and use the same transmission and hybrid system. They are all rear-wheel drive. This approach dramatically cuts development costs. Cadillac and Porsche will each field LMDh entries in this year’s Le Mans.
