While the ACO has yet to formally announce its proposal for the 2017 LMP2 regulations, IMSA confirmed Saturday that the TUDOR United SportsCar Championship will feature some key differences once the new rules are confirmed.

Despite the FIA confirming last month the use of a single engine supplier, the TUDOR Championship will continue to allow multiple engine manufacturers in its top Prototype class.

Additionally, manufacturers will also have the option to incorporate limited styling cues into the original bodywork supplied by each constructor.

All TUDOR Championship Prototypes will be eligible to compete in the 24 Hours of Le Mans in the same drivetrain configuration.

However, the original constructor-specific bodywork will be required for the twice-around-the-clock French endurance classic.

“IMSA, the ACO and the FIA are diligently working toward the common goal of ensuring competitive Prototype racing for teams and drivers worldwide,” said IMSA President Scott Atherton.

“We all are in agreement that close competition with sustainable budget and business parameters is “the way forward for all involved.

We also recognize that we must retain a platform to attract multiple automotive manufacturers to participate in the top class of the TUDOR Championship.”

Additional details on the global 2017 regulations will be released in June during the week of Le Mans.
