Not a lot difference between GT3 & GTE cars the only difference between both cars are aero parts, engine power outputs & GTE cars don't have ABS. The GT3 have more aero compare to GTE cars but GTE cars have more engine power. Lamborghini were planning a GTE version of Huracán but has Porsche has a competitive car within the GTE glass Lamborghini would be competing against the same brand affect being owner by VW we all know how that end LMP1 glass. Ferrari use same chassis between GT3 448 and GTE version but version different aero parts whilst Porsche don't has GT3 is rear engine and GTE mid engine.
Perfect explanation for me. Thank you.
