After more than two years of meetings, with the target of developing a common set of base regulations to be used worldwide, GT convergence talks have been called off.
Multiple manufacturer sources have confirmed to Sportscar365 that the FIA and ACO’s proposed new set of rules, which was set to be approved at next month’s World Motor Sport Council meeting and to be used beginning in 2016, has been nixed in favor of continuing with the separate GTE and GT3 platforms for the foreseeable future.
The reversal apparently stems over a discrepancy with the types of air restrictors that were to be used for the earmarked GT+ and GT classes.
It’s understood the FIA proposed a new torque sensor “accelerator” method, while many of the current GTE manufactures were instead in favor of remaining with a sonic air restrictor.
A decision to continue with the current formula was handed down late last week following a vote from the manufacturers.
While the majority of manufacturers were in favor of a single GT platform, SRO founder and President Stephane Ratel had declared he remained 100 percent committed to the GT3 formula, which could have additionally complicated matters, if his series was not to adopt the new regulations.
The concept for the proposed GT+/GT regulations centered on a common, manufacturer-specific chassis and base components between the two classes.
GT+, which was to replace GTE-Pro/GTLM, was to feature further mechanical and aero upgrades over the GT class cars, which were to be reserved for privateers and replace the GT3 platform.
No immediate changes are expected to be made to the current GTE and GT3 formulas, although an additional manufacturers meeting is scheduled for June 6, which could reveal further details on future plans.
