"You've no doubt heard about Kia's big engineering coup, stealing Albert Biermann from BMW's M division with the mission of giving the Korean automaker's cars a much-needed dynamic zhooshing. It's worked, too. On a familiar set of canyon roads northeast of Los Angeles, the Stinger shines. The rear-wheel-drive GT dives into a corner with only the slightest hint of understeer. The car stays flat as a wealth of information is delivered through the thick steering wheel. I know exactly what all four of those sticky Michelin Pilot Sport 4 tires are doing at all times, and even in its full-on mode, the traction control is letting me play a little, loosening up the rear end a bit to help that pretty rump shimmy through a turn. Big Brembo brakes offer solid stopping power, with confident feel through the pedal. Optional all-wheel drive can be had for $2,000 if you want it, but on these sun-drenched LA roads, the rear-drive car's playful rear end has me smiling.
"Off the main road, the quicker motions and tighter turns of an autocross course reveal a number of little motions in the suspension, all of which are felt through the Stinger's body. This is a chatty chassis, especially talkative when pushing the Stinger very hard. A comparative lap in the Audi A7 exhibits a bit more composure in the tight corners, but my seat-of-the-pants feeling is that I'm faster in the Kia.
"I'm happy to report that steering feel -- a longstanding sore spot for Kia and parent company Hyundai -- is mostly good here in the Stinger. In its default setting, there's no on-center dead spot or false sense of weight to the wheel's action; heft builds progressively while cornering. But a sour Kia trait rears its head when I turn the drive select button to Sport -- there's no improvement, just added resistance that doesn't actually result in better steering action. On the other end, turning to Eco mode results in overboosted lightness."
