2018 Kia Stinger GT Long-Term Review Update | Do we like the seats?

We've had our long-term 2018 Kia Stinger GT for over six months, which means we've all had a lot of seat time in the sports sedan. And those seats we've become so familiar with have stirred up some mixed opinions among the staff, which I discovered after voicing my personal dissatisfaction with the shape of the seats. In my experience, I've found the seats to offer too little lumbar support, and with short, flat bottom cushions that aren't angled to support my thighs. Managing Editor Greg Rasa and Consumer Editor Jeremy Korzeniewski agreed the seat bottom would be better if it was angled up more, but otherwise didn't have complaints about the shape. Korzeniewski also mentioned he doesn't care for aggressive lumbar support, so the Stinger seat felt fine in that regard. Editors both lighter and shorter than the aforementioned folks didn't have any complaints. Road Test Editor Reese Counts felt they were supportive enough with good adjustability. "I've got a bad back, but I was feeling fine when I got home," Counts said, referring to a road trip to St. Louis in the car. "They're not the best seats I've ever tested, but the fact that I don't think about them very much speaks for itself." Senior Producer Chris McGraw said: "I'm 5'7" and weigh 150 pounds on a good day, so I wasn't really pushing these seats to their limits. They were comfortable for long highway stretches and offered enough support when I decided to push the twin-turbo V6 while driving around some of West Michigan's curvy roads." There is something about the seats that drew near universal derision, though: the combination of interior and exterior colors. Our Stinger GT is red with a red interior, and Counts, Korzeniewski and Rasa were annoyed that the reds don't quite match. McGraw felt it was "a bit too much The Shining to me," a reference to the vivid red bathroom in the movie. I like lots of color, and wasn't put off by the mismatch, so was perfectly fine with the color scheme. No one actually disliked the red leather itself, though, and Rasa offered a solution we all could agree on, "Just don't get that combo." We all agreed the red interior would look excellent with contrasting exterior colors such as white, black and blue. And it seems that even Kia agrees, since it appears that the red-on-red combo is no longer offered on the Stinger. Related Video:

Hyundai CVVD engine brings another dimension to valve timing

A new technology from Hyundai Motor Group places another marker on the march to more efficient internal combustion engines. Called Continuously Variable Valve Duration, the innovation permits two options for how long the intake valves remain open during the combustion cycle. The feature adds a third take on valve chicanery, atop variable valve timing that changes when valves open, and variable valve lift that changes how far valves open. Hyundai says the feature returns a 4% improvement in performance, a 5% increase in fuel economy, and lowers emissions by 12%. Hyundai applied for two patents on the valvetrain process in South Korea in 2011 and again in 2015. The altered valve duration in this latest iteration is made possible by two movable arms inside the camshaft. Each arm is anchored at its base to a pin at the center of the camshaft, while the end of each arm extends toward the edge of the camshaft. Changing the position of the pin in the center of the camshaft changes the angle of the arms relative to one another, which moves the camshaft along its mounting rod. Voila, a new intake cam profile that either lengthens or shortens valve overlap.   During low-speed spells at low load, CVVD opens the intake valve from the middle to the end of compression stroke. The weaker detonation isn't a factor at low load, and the reduced friction during compression improves fuel economy. During heavy engine loads, the intake valve closes at the beginning of the compression stroke to maximize the amount of air mixed for detonation, boosting torque. Four additional features enhance the benefits of CVVD. A more powerful direct injection system increases fuel spray pressure from 250 bar to 350 bar. Hyundai doesn't go into details on its Integrated Thermal Management System, but says the ITMS "quickly heats or cools the engine to the optimal temperature." Low-friction components lower overall engine friction by 34 percent. And a low-pressure exhaust gas recirculation layout diverts low-pressure exhaust gas from the traditional EGR route to the turbocharger compressor under high load for better fuel efficiency.   The first engine to boast the new tech is the Smartstream G1.6 T-GDi four-cylinder, which produces 180 horsepower and 195 pound-feet of torque. It will appear in the 2020 Hyundai Sonata Turbo going on sale in South Korea later this year.
