People see this car and based upon it's looks and power ratings want it to go against AMG, M and RS cars by doing a high performance version that will be higher in price than people would think of paying for "a KIA". This needs to get out in the market as is so folks can experience it and see that yes, it is a KIA and yes, it performs as well as and better than some cars in it's price point, and as well as the cars it was designed to compete against. Sure folks are comparing it to the Accords and Camrys on the lower end but when you point out the A5, 4 Series Gran Coupe, they are like no way! Have them do a build and they see the price that these cost with the equipment they want, then look at the Stinger and see comparatively on price, you are getting a powerful V6 and the other guys are giving you a 4 cylinder, they start talking about KIA of 20 years ago that some friend's mom had. Show them a few video of the car and what presenters are saying and they always pick up on the points about it not being a true luxury car but mis that it does hold it's own against the ones it competes with. Only thing left is to drive it and some eventually will.
So for the normal daily drive, the car has more than enough power and manages to drive and handle like the the luxury cars. Is it worth the $12-15K for the luxury badge with a lower performing engine, the answer always is no but now they have to decide if they really want to be seen or have to tell their friends they drive a KIA. Tell you what, for a first effort, this car has a lot of folks talking and is pulling in buyers from luxury brands. This people, is the KIA with the power to surprise!
