The long road to convergence for sportscar racing's new golden age

By:

The organisers of the World Endurance Championship and IMSA SportsCar Championship worked together to devise the popular new LMDh rule set. But to turn it from an idea into reality, some serious compromises were involved - both from the prospective LMDh entrants and those with existing Le Mans Hypercar projects...

It was a historic moment. The great and good from the Automobile Club de l’Ouest and IMSA sat on stage and told the racing world what it had wanted to hear for years: that the same cars would battle it out for the overall victory at the Le Mans and Daytona 24-hour endurance classics and right across the two series. An announcement, you might think, deserving of a 21-gun salute from the National Guard or a ticker tape parade through the streets.

Yet for all the euphoria on the eve of the 2020 Daytona 24 Hours when the convergence between the top-class prototype rules of the two governing bodies was revealed it was just a staging point – perhaps a flag-in-the-sand moment – on a long and winding road. There was still work to be done to align what was now being called LMDh, the category that had grown out of IMSA’s vision for a successor to the Daytona Prototype international class, and the Le Mans Hypercar rules of the ACO and the FIA. It would be another 18 months or more before sportscar racing nirvana, on the verge of which we now stand, was achieved.

How Porsche's Le Mans legend changed the game

The 956 set the bar at the dawn of Group C 40 years ago, and that mark only rose higher through the 1980s, both in the world championship and in the US. It and its successor, the longer-wheelbase 962, were voted as Autosport's greatest sportscar in 2020 - here's why

Why BMW shouldn't be overlooked on its return to prototypes

OPINION: While the focus has been on the exciting prospect of Ferrari vs Porsche at the Le Mans 24 Hours next year, BMW’s factory return to endurance racing should not be ignored. It won't be at the French classic next year as it focuses efforts on the IMSA SportsCar Championship, but could be a dark horse in 2024 when it returns to La Sarthe with the crack WRT squad

Why Peugeot couldn't afford to take a Le Mans gamble in 2022

Ahead of the much-anticipated arrival of its new 9X8 Hypercar, Peugeot revealed that it would not be entering this year's Le Mans 24 Hours with its incoming machinery. Although development restrictions for homologated cars are partially responsible, the French marque can draw on its own lessons from its history in sportscars

Why two names for the same thing could cloud sportscar racing's new golden era

OPINION: The adoption by IMSA of the GTP name for its forthcoming LMDh versus Le Mans Hypercar era in 2023 appeals to fans of nostalgia - but it undermines the commonality achieved by bringing its rulebook into line with the World Endurance Championship. GTP or Hypercar, both sides should settle on a single name
