Losing a couple hundred pounds could really liven the car up, especially as they looking to go with alternative powertrains. If they are downsizing the car, it makes me wonder just how small they'll make it.
I'd love to see how close they could get it to the original Mustang, actually.
Growing up in the UK I was pre-conditioned into thinking all American cars were huge, so the first time I saw a Mustang it surprised me. Okay, so it's big compared to a European car from the 1960s, but since modern cars have all grown massively since then it actually looks nicely-sized by modern standards. Whereas the current Mustang
does look quite big.
Make it small fine, but, give it some brutish American looks.
I can understand the appeal of this, but I think it's incredibly hard to do thanks to the various modern regulations.
Brutish good looks were a lot easier when all you had to do was design a body that looks great, and bung a big engine in it wherever you fancied.
Now, you have to design a body that looks great... but make sure it's aerodynamic, has the required crumple zones etc, sets aside enough space for front and rear passengers, luggage, the engine, airbags, and all manner of other technologies. Some of those preclude others so it influences the styling.
I quite like the current Mustang, but realistically I'd say it looks more cartoonish than brutish - ditto the current Challenger and Camaro, both of which I also like but all of which also look a bit heavy-handed compared to their 60s/70s namesakes.
^ That is my favorite "future" Mustang.
Not keen on the proportions. The cabin looks too low and too far back, as if it's from a different car entirely. And really, everything below that cabin is pretty much what the current Mustang looks like anyway.
