The current Daytona Prototype and Prototype Challenge cars are set to end their run in the Tudor United SportsCar Championship after 2016, and their replacements are still to be decided.
Daytona Prototypes, along with LMP2s and a DeltaWing, make up the top class, Prototype. The Prototype Challenge class is a single-make class featuring the ORECA FLM09.
With LMP2 changing for 2017, the future of the top classes in the USCC are uncertain, as it is unclear whether the North American championship will feature solely LMP2s, or if other formulae will be allowed to enter.
At the moment, it appears that the options for 2017 are DP, LMP2, LMP3 and PC, but it is unlikely that IMSA will choose to use more than two of these.
A test with the new-for-2015 LMP3 cars is scheduled to take place at Watkins Glen in June. This new class has already been proven a success in the European Le Mans Series, and IMSA are considering bringing it over to the USA.
More details of the ACO’s 2017 regulations are expected to be announced during the build-up to the 24 Hours of Le Mans, in early June.
