The car seems to be very well conceived and certainly seems to deliver on the numbers. Given the designer and the engineering in it, I suspect it will be a solid driver, too.
The styling doesn't resonate with me, so it would be a difficult sell in my case. I don't think I'm exactly the audience they're going for, though. For me, a car is a bunch of intangibles as well as the empirically observable. There is simply something about German cars that calls to me, despite the (often) grossly inflated prices, bloated and inefficient options structures, and flat-out jobbery that comes with the four circles, the three-pointed star, and the roundel (VW pretty much avoids these things, but then, they have exactly two cars I'm interested in, both Golfs).
I think for Hyundai something like this could be successful, and I think for the young male demographic the styling seems aimed at it could be a hit. It's not for me, though, not really.
