The world's premier endurance racing series — eight manufacturers, six continents, and one race that defines the entire sport: the 24 Hours of Le Mans.
WEC races across the globe — Qatar, Imola, Spa-Francorchamps, Le Mans, São Paulo, Fuji, and Bahrain are typical calendar fixtures. Unlike F1 or NASCAR, WEC races are 6 hours long at most venues, with Le Mans being the headline 24-hour event.
While WEC awards championship points at every round, the 24 Hours of Le Mans carries double points and carries the sport's greatest prestige. A team can lead the WEC championship all season and still consider their year a failure if they don't perform at Le Mans.
The LMDh formula created cars that race in both WEC and IMSA simultaneously. The Porsche 963, Cadillac V-Series.R, and BMW M Hybrid V8 that race at Daytona and Sebring are the same cars that start at Le Mans. The two series have never been more connected.

If you've been following IMSA, here's how WEC connects to what you already know.
The single biggest change in endurance racing over the last three years is the LMDh (Le Mans Daytona h) formula — a shared technical regulation that lets manufacturers build one car to compete in both IMSA's GTP class in North America and WEC's Hypercar class in Europe.
Before LMDh, manufacturers had to choose: either build an IMSA prototype or a WEC prototype — the rules were different enough that a single car couldn't do both. Now, a team can run the same car at Daytona in January, Sebring in March, Spa in May, and Le Mans in June.
This shared formula has dramatically increased manufacturer participation. Porsche, Cadillac, BMW, Lamborghini, and Alpine all run the same basic chassis architecture in both series. The racing knowledge, data, and driver experience accumulates globally rather than in separate silos.
Despite the shared cars, IMSA and WEC feel quite different in practice. IMSA races at iconic American venues — Daytona, Sebring, Road America, Laguna Seca, Petit Le Mans at Road Atlanta. WEC races at historic European circuits and international venues. IMSA has four classes per race; WEC has two. IMSA fields tend to have more entries in the GT classes; WEC has the deepest Hypercar grid.
Following both series gives you the complete picture of global endurance racing — you'll see the same cars and many of the same drivers in radically different contexts. And when the Le Mans grid lines up in June, you'll already know the cars.
