This issue has persisted since the first Forza Motorsport on the original Xbox. Yes, a car that has not been featured in Forza for over a decade has inaccuracies carried over from 2005. The Mitsubishi FTO is deformed in a manner typical for Motorsport 1 models. About every single aspect of the body is wrong, and even details were poorly carried over. It looks more dated than it did in Motorsport 4.
While the comparison footage here is taken from Forza Motorsport 2023, the model is identical in Horizon 5
The entire front end is squished, with the bottom part of the front bumper being too high and the bumper-bonnet line being too low. The roof line isn’t round enough, and so is the rest of the body. The wheels lack detail in all ways.
The rear end is disproportionate too, mainly the taillights that are too big. The only remaining aftermarket body kit that’s available on this car is carried over from Motorsport 1-4, and of course it is inaccurate as well. Typically for pre-Xbox One models, the panel gaps are too big and pre-shadowed.
The fact that after 11 years of not featuring the FTO as a playable car in any Forza game we get a model that’s more deformed than an actual PlayStation 2 game model is outrageous.
