In what sense? I mean the cars are built to the spec of the sport, and fit in with that. If teams like Porsche, Aston, and Chevy don't have a V8 tt or V6tt why should they go back and spend tons of money R&D wise to do it. It's quite the cop out to say "they just built a better car" when realistically in the real world the GT isn't anywhere near a Z06, 911 turbo or V8 Vantage... The 488 might be.
They brought a car that fit the rules, and what failed them was that the ACO some how forgot how to BoP NA vs Turbo. When they've done it for years at the very top of the ladder. So does this mean that Chevy should be allowed to bring a Supercharger next year, and Porsche a tt inline six mid mounted? And what happens when they go unreasoanblly fast after not seeming so, would you say the same thing? Cause I wouldn't I'd be mad if my team deviated from what I've seen them do for year after year which is go out there show what they have and race hard to win.
Ferrari, not surprised by this, they pull this crap everywhere they go. Ford I expected better.
