Class Specs For USCR Taking Shape


On to the headlining Prototype (P) class, where series officials are working overtime to balance performance between the ALMS’ P2 cars, DeltaWing and Rolex Series’ Daytona Prototypes. That work continues but there are these definite mandates:

– Cars considered P2 in origin will follow current technical specs of the ACO

– Paddle shifters and 6-speed transmissions /gearboxes allowed for all cars

– Sonic air intake restrictors for all approved engines for P2 and DP cars

And lastly, here’s the easy one: The popular and highly competitive Prototype Challenge (PC) class now competing in the ALMS will return with all current technical aspects intact.

Cars in every class except for PC will also carry series-mandated data loggers, which will be downloaded on every pit stop. Teams will be responsible for the proper operation of the data loggers.

To help delineate the classes, each car will use standardized number panels with colored backgrounds identifying each class, similar to what is being used currently in the ALMS. The panels will be backlit for night races.

Another feature sure to be popular with fans is the return of a new and improved Leader Lights system, which will be required on all cars. The colored lights, which will be similar in color to the number panels, will enable fans to determine each car’s running position within its class at all times during United SportsCar Racing events.

“We are moving carefully, but with clear momentum,” said Scot Elkins, chief operating officer of IMSA and the ALMS and managing director, technical regulations and development for Grand-Am. “The goal is to get it right, which entails making the on-track action safe, competitive and reasonable when it comes to cost. Like we’ve said all along: the ‘best of both worlds’ is what we’re after here. We’re getting closer each and every day.”
