Overall I am pretty happy with it. I have AutoX'd it one time...and I'll do my best to answer your questions.
It drives like a slightly smaller and lighter car. I have owned Miata's, Fiat 500 Abarth's, and A3's...and it is NOT a small car, but it drives smaller and lighter than it is. I think the effortless acceleration helps here.
The stock tires SUCK! They tram like crazy, and follow the crown of the road. I have since replaced them, and find general straight tracking, ride quality, and cabin noise MUCH BETTER.
When I AutoX'd it (stock tires)...the weight became very apparent. In day to day spirited driving, it does really, really well...but when pushed in the tight confines of an AutoX track, it becomes extremely apparent just how heavy it is. It punished the fronts tires, and pushed hard into corners. Even with all stability and nannies turned off, it was still tough to get any sort of oversteer (MUCH unlike my C5). Acceleration and braking were AMAZING.
Day to day, it is a FUN car! I enjoy roasting anybody I care to with even half throttle. It is quiet, and drives really nice...even my bride loves to drive it...and I have to say I think this is the first car that was "mine" that she actually enjoyed driving. She drives in normal mode...it is a bit stiff when compared to a normal 4 door CUV, and throttle and brakes are responsive, but not crazy. I drive in sports mode which stiffens it a bit more, and increases responsiveness. GT mode is a ton of fun, but cruise does not work in that mode :-( otherwise I would drive in GT all the time.
I easily get the 200+ miles out of a charge. I normally only charge it to 80% to prolong battery life, and usually charge it when down to 20%. I have taken a few road trips that require stops, and the quick charging time is appreciated when you can find the right charger.
