The new year brings the start of a new era for the IMSA WeatherTech SportsCar Championship, which will open the 2023 schedule with the 61st running of the Rolex 24 at Daytona.
A new premier class for prototypes is the overriding story entering the 24-hour endurance race that unofficially kicks off the major-league racing season.
The new Le Mans Daytona hybrid (LMDh) cars of the Grand Touring Prototype (GTP) top category will re-establish a bridge to the 24 Hours of Le Mans while bringing a new layer of engine electrification to IMSA.
With at least a few of the cars on the grid at Daytona also slated to race at Le Mans in June, it’s possible for the first time in decades (since the “Ford vs. Ferrari” battles) to have the same car win the overall title at Daytona and Le Mans.
The GTP category will feature four manufacturers, two of which are new to IMSA’s premier division. Porsche Motorsport (with Team Penske) and BMW (with Rahal Letterman Lanigan) will be fielding LMDh prototypes, joining (now-defunct) DPi category holdovers Acura (Meyer Shank Racing, Wayne Taylor Racing) and Cadillac (Chip Ganassi Racing, Action Express Racing).
