IMSA Extends LMP2, DPi, GTE Homologation Periods

IMSA has extended the homologation periods for LMP2, DPi and GTE-spec machinery in the WeatherTech SportsCar Championship by one year each, the sanctioning body confirmed on Wednesday.

It comes following the FIA World Endurance Championship’s transition to a winter calendar, which has delayed the homologation periods in the globe-trotting series by roughly six months.

IMSA DPi and LMP2 machinery, originally confirmed for a four-year period through 2020, will now be eligible until at least the end of the 2021 season.

GTE-spec cars, meanwhile, will be extended through the 2019 WeatherTech Championship season.

The current homologation period for LMP2 will be until the 2020/2021 season-ending WEC round at Le Mans, with GTE cars confirmed through the end of the upcoming ‘Super Season’ only.

The change indicates that any new-generation GTE cars would likely now debut in WEC competition prior to the WeatherTech Championship season the following calendar year.

WEC CEO Gerard Neveu revealed plans for the 2019/20 season to start in September or October, some three to four months prior to the WeatherTech Championship kicking off in Daytona on January.

The extension of the current LMP2/DPi regs also provides additional time for potential discussions with the ACO and FIA on a common prototype platform, initially proposed for 2020.

    I hope we can get some convergence, a global prototype platform and a common gte-gt3 platform seems too logical based on how well its worked for LMP2-DPi – the weakest class at Daytona is the GTLM – a pretty clear reflection of its increasingly isolation in my opinion

      Cause GTLM is uber expensive. Only car manufacturers have the resources. More praise for Risi then to stick it to the deep pockets. GT3 is too much now.

      As long as the manufacturers want GTLM, it’s going to stick around. Once they get tired of spending the money on it, IMSA will probably converge GT into one class. But no guarantee the manufacturers will grow tired of GTLM.
