I will hold my judgement until someone tests a US-spec 2.0T and/or I drive one. I would also expect people who want a "driver's car" to just pay the extra 2k for the base GT.
The customer base that values "driving dynamics" is way too small to target and expect a sales success. It also has you completing with models you didn't intend to (hot hatches and the like). Also, when it comes to "performance" a lot of your "average" customers measure that in a straight line. For merging, passing, etc.
I actually didn't bring up the Accord et al comparison on this thread. But it aligned with my standing criticism, which is almost exclusively focused on content vs. price. An area where I think Kia has failed pretty badly. The highest trim Accord is $36,675. It has MORE amenities/options than the $50,395 GT2 Stinger. Things like wireless phone charging, heated rear seats, rain-sensing wipers (can get this for 2200 bucks but you have to take AWD too), WiFi HotSpot, advanced 10-speed transmission, remote start, etc. Honda even added a resonator and resin molding to the inside of the wheel rims to reduce road noise by 6bD.
So even if we add the "driver's aid package" to the 2.0T Premium to get all the safety features (most of which are standard on the 23K base Accord) you are still missing everything I listed above plus HUD, adaptive shock absorbers, ventilated front seats, 19-inch wheels, etc. and it will cost you $39,895.
I don't see people paying more money to move up from non-luxury sedans to loose content, fuel economy, better depreciation, etc. and purchase a 2.0T model, even it is more fun on a back road.
