IRL the I-type 3 is 5,16 m long and 1,77 m wide. Now let's compare that to something like McLaren Senna. 4,74 m long and 2,15 m wide. F40, that's 4,36 m long and 1,97 m wide. Camaro ZL-1 is 4,81 m long and 1,90 m wide. So even though these card are shorter than I-type 3, all of them are in fact wider.
Case in the point Lego is taking a very narrow racing vehicle and making it 8 wide here, which I'm not a fan of. The leaks mentioned a Lambo twin pack though, if that has Miura then I'll probably have to get it. Personally I don't believe it will though, they'll probably go with Aventador + Countach or something.
