And after a long time trying to observe the models of FTO between The Crew and Forza, I have finally confirmed that the models look the same between the two different racing game franchises, I can see the “disproportionate” front-end like the “low” front bumper and these “wrong” headlights also exists in The Crew’s FTO, but I guess nobody knows that. 
Fact is - it arrived in TC2 and Motorfest before it returns to FM8.
The Crew FTO
Forza FTO
Turns out as we know, the model was indeed outsourced. It’s from the same outsourcing company - GLASS EGG. They also outsource The Crew’s car models, but I think the majority of them were in separate model looks.
