GT ‘Harmonization’ Talks Intensify

The FIA has continued talks for ‘harmonization’ across the GTE and GT3 platforms, with a set of technical measures having been proposed to manufacturers.

The latest development was revealed during Wednesday’s World Motor Sport Council Meeting in Paris, which sees a further step towards a potential correlation between the two GT formulas.

It comes nearly four years after GT Convergence talks were called off, following proposals for a single platform with two tiers of performance levels.

While details on the proposed measures have yet to be confirmed, it’s understood any significant changes to the technical regulations are unlikely until 2022 at the earliest, at the start of a new homologation period.

The next homologation period for GTE and GT3, to run from 2019-21, is poised to remain relatively unchanged to the current set of regulations.

Unlike GT Convergence, which was to see a single platform, it’s believed the FIA’s latest proposal could keep both GTE and GT3 as separate classes but allow for an easier exchange between platforms.

    Excellent news! As much as I love the current GTE field and their factory powers, i’ll be remiss to say that there are glaringly no real privateer GTE pro efforts. I think this may only get worse as GTE-Pro evolves into a mini-prototype minefield for funding and competition.

    While this isn’t this homologation talks we saw a few years ago, a shift towards swap-able parts or chassis for each class will tremendously help privateer outfits towards attending and being competitive in world class events and championships world round. If the direction is towards more compatibility with signature races and their regulations, this is welcome, welcome news,

      Agreed. Got a hand it to Ferrari with the changeable 488. A good role model.

    If you put Michelan tires and ease the bop on the GTD cars, then they will be very close to gtlm.

      Yeah GTD will be closing in on GTLM cause their budgets sure are closing in on GTLM costs currently.

    I can’t imagine taking away yet another step in performance (so I am more than okay w being able to upgrade chassis/engine/electronics/aero/suspension/tires, etc to differentiate) between GT3 and GTE/GTLM.

    Remember GT1 and GT2, they were ultimately priced out of existence, but you need a decent gap between classes -and you need those classes. IMHO.

    With any of those changes, costs and development can be kept under control while performance steps are readily made.

      GT2 wasn’t priced out of existence. GT2 became GTE after GT1 ceased to exist.

    I know this doesn’t help with cost but i think GTE cars are under powered.

      Think most people would agree.

      They were supposed to jump 50HP 2 years ago and then they never actually did because IMSA and the ACO BOP’d them all back to where they started. But yeah, GTE cars should have 700hp. It’s almost 2018, it’s not that hard to non-expensively make this much power. GT cars had 700hp in the 80’s.
