Kia GT4 Stinger concept headed for Detroit with 315 rear-drive horsepower

With reveals expected to include the 2015 Ford F-150, the new Chevrolet Corvette Z06 and the high-strung Lexus RC F performance coupe (among many others), there are plenty of vehicles we're looking forward to seeing at the Detroit Auto Show. But now, with a rendered teaser image and short press release that includes some savory details, Kia may have just hit the top of our list with its GT4 Stinger Concept. Not even looking at the above image (which you can click to enlarge), Kia managed to grab our interest with just one sentence in said release detailing the car's powertrain: "A turbocharged 2.0-liter that pumps 315 horsepower to the rear wheels."
This low, wide concept has the face of a Kia-fied Audi R8, but the previous teaser stated that the concept will be a 2+2 hatchback. There is little other information to go on, but we'll see the concept car live in just 10 days. Until then, scroll down for the brief press release.

Automatically efficient | 2017 Kia Optima Hybrid Quick Spin

Automakers are stuck between a rock and hard place with hybrid vehicles. On one hand, efficient hybrids are a necessary evil – for lack of a better phrase – to hit increasingly stringent CAFE standards. But on the other hand, low fuel prices mean it takes an increasingly long time for consumers to see a return on the investment of a hybrid's price premium. These factors have pushed automakers even harder to squeeze every mile per gallon possible out their hybrid offerings. That's inevitably led to powertrain innovations designed to maximize just how long and how far hybrids can run on pure electric power and how often the gas engine can shut down. Occasionally, this doesn't work out all that well – as is the case with the new Nissan Rogue Hybrid, for instance – but there are companies getting things right. Kia, with its 2017 Optima Hybrid, is one of them. Drive Notes Kia didn't try to get too creative with the Optima Hybrid's powertrain for 2017. There's a 2.0-liter, naturally aspirated, four-cylinder gas engine, a 38-kilowatt electric motor, and a 1.62-kWh battery pack. Total system output is 192 horsepower and 271 pound-feet of torque, with EPA estimated fuel economy ratings of 39 miles per gallon in the city and 46 mpg on the highway for a 42-mpg combined rating. That's all spiffy. But taking a six-speed automatic and replacing the torque converter with a clutch and the electric motor, Kia built a hybrid sedan that smoothly intertwines disparate power sources as well as a conventional hybrid like a Toyota Prius, while allowing the Optima Hybrid to take greater advantage of zero-emissions systems. Lift off the throttle and the four-cylinder engine shuts down and lets the 50-hp electric motor handle light, constant-throttle cruising below 62 miles per hour. Dig deeper into the gas, and the petrol powerplant quickly restarts and delivers the bulk of the Optima's power for heavy acceleration and higher-speed conditions. The Optima's back and forth is rarely disjointed – Kia's hybrid feels a lot like its conventionally powered model in normal driving. It's only under sudden, wide-open throttle situations, where the hybrid systems feel caught off guard, that the Optima Hybrid feels flatfooted. A less obvious benefit of the six-speed automatic, of course, is that it leads to quieter operation. There's no rubber-band-like revving like you'd get with a CVT because the transmission can actually shift up a gear.

Hyundai and Kia to update EV brake lights; our tests show how they currently may not come on

Update: This article has been updated to reflect Kia's own service campaign announcement.  Hyundai will be launching a "field service campaign to update the EV brake light logic" on its Ioniq 5 as well as the Genesis GV60, Electrified GV70 and Electrified GV80. According to Hyundai's director of communications, Michael Stewart, the change will be make to new production vehicles and as part of free-of-charge service campaign that will launch in July for approximately 56,000 vehicles already on the road.  "Regardless of the accelerator pedal input, the brake lights will now turn on when the deceleration rate exceeds approximately 0.13 G," Stewart wrote in an e-mail to Autoblog. Since this article was originally published, Kia has announced it will be performing the same update to its EV6 and Niro EV. Kia is also part of the Hyundai Group. This change would seem to be in keeping with the behavior we have experienced in the Hyundai Ioniq 6, the firm's most recently introduced EV. We go into that behavior lower in this article.  This announcement comes in the wake of owner complaints as well as a test by Consumer Reports that found that most Hyundai, Genesis and Kia electric vehicles can come to a stop without their brake lights illuminating. This occurred when using those vehicles' most aggressive "i-Pedal" function that allows for so-called "one-pedal driving" where the driver can mostly rely upon the car's regenerative braking system (which is used to replenish the battery pack) to stop the car.  We tested this for ourselves this week as we are currently testing a Genesis Electrified GV70, and I personally own a 2023 Kia Niro EV Wave. I almost exclusively drive in i-Pedal mode. News Editor Joel Stocksdale tested the Hyundai Ioniq 6 in Michigan, and again, we will address his findings after the Genesis and Kia as they are completely different. I attached an action camera to the rear of each car and conducted the same test in both: Accelerate to 40 mph and come to a stop without touching the brake and, crucially, without lifting my foot fully off the throttle. The result as you can see below with the Niro is that the brake lights do not come on until around 3 mph when I fully lifted off the throttle and bring the car to a full stop. I could not bring the car to a full stop without fully lifting off the throttle.
