Same engine, probably detuned. I kind of like the design after seeing what the production model will look like vs the leaked photos.
I like that it is smaller like the M3's in the past like the E46, looks like it is 3700lbs though, that is near the G82 weight. The only thing I still don't like is the rear. Maybe it will be better in person like the G8X front end.
It is built in Mexico, I am pretty sure a bunch of people will not like that. It doesn't bother me at all as it is the manufacturing process that is important, not where it is built.
