Kia U.K. builds a 420-horsepower Stinger GT track car

The Kia Stinger GT is an admirable sports sedan, er, hatchback, with 365 horsepower. But Kia's U.K. branch wanted more, leading to the 420-horsepower Singer GT420 you see here. As Kia explains, the car used to create this one-off track car is actually the first Stinger GT pre-production test car in the U.K. It was used for final testing, photography, and was even featured on Top Gear and The Grand Tour. Once its testing and publicity duties were over, though, it was slated to be crushed. But some delaying and the idea of building a track car saved it. To get it to its final output ratings of 420 horsepower and 413 pound-feet of torque, Kia (with help from Hyundai Motor Group's technical team in Germany) added a high-flow air filter, aftermarket exhaust without catalytic converters, an upgraded transmission cooler, and an engine tune. The car also benefits from weight reduction: The whole car was gutted, taking out everything unnecessary for speed such as the sound system, rear seats, carpeting, bumper supports and more. Even with the addition of a roll cage and extra chassis braces, the car is just over 330 pounds lighter than stock. Handling and stopping capabilities were also enhanced with stiffer springs and thicker anti-roll bars, along with six-piston brake calipers and brake cooling ducts up front. The car also gets visual changes in the form of a front splitter and rear spoiler and diffuser, plus the bold vinyl wrap. Naturally, this isn't a production car, especially with the gutted interior and emissions non-compliant exhaust. But looking at the list of modifications, it wouldn't be hard to replicate the Stinger GT420 on your own. In fact, someone could probably exceed the car's performance, since there are some areas ripe for upgrading Kia skipped over, such as upgrading the turbochargers. Your move, tuners.

2020 Kia Stinger GT-Line becomes only 2.0-liter model on offer

The 2019 Kia Stinger comes in five flavors: 2.0L and Premium with the 2.0-liter turbocharged four-cylinder engine, and GT, GTS, GT1, and GT2 with the 3.3-liter twin-turbo V6. Beyond the engine, the two lowest trims differ from the GT versions with different grilles, bumpers, wheels, and exterior trim. Having seen an early order guide, CarsDirect says Kia will replace the two base models with a single model that's been restyled with GT cues, while raising the price just $100. The new model is called the Stinger GT-Line, a trim that's been available in other markets for a while on everything from the tiny Picanto to the Sorrento crossover; the pictured car is a UK Stinger GT-Line. The model bolts on the grille and bumpers from the GT, black chrome trim and body-colored door handles, plus 18-inch GT-styled wheels. The cabin gets dressed up with a black headliner no matter the interior color, a leather-wrapped steering wheel, and headrests embossed with "GT-Line." The price will be $33,090 plus $995 destination, totaling $34,085, a figure that comes in an even $100 above the 2019 Stinger 2.0L. $34,085The loss of the Premium trim leaves a $6,410 gap between the GT-Line and the base GT trim. The Premium was the way to get a long list of luxury and convenience features paired with the four-cylinder, but it was only $110 less dear than the entry GT with the bigger engine but without the feature set. The price of that GT goes up, meanwhile, CarsDirect saying the 2020 GT will start at $40,495 after destination, a $200 increase over the 2019 model. Furthermore, with the Premium gone, the only way to option automatic emergency braking will be to spend more than $46,000 on the GT1 grade.  Engines don't change for next year, the 2.0-liter producing 255 horsepower and 260 pound-feet of torque, the 3.3-liter putting out 365 hp and 376 lb-ft, both shifting through an eight-speed automatic.

NHTSA investigating 8 million airbags not made by Takata

In a shocking turn of events, we have a line of airbags under investigation that weren't made by Takata. Rather, Automotive News reports that 8,000,000 airbags made by ARC Automotive Inc. are under investigation by the National Highway Traffic Safety Administration (NHTSA). According to Automotive News, NHTSA is looking into ARC's airbags after two injuries and a recent death were attributed to the company's products. The two injuries occurred first and prompted the initial inquiry of 490,000 airbags, which then expanded after an airbag from a different line caused the death of a Canadian driver. The airbags in question are found in GM, FCA, Hyundai and Kia products, and all automakers are cooperating with the investigation, Automotive News reports. It is also important to note that these airbags have not been recalled, as NHTSA is trying to determine the issue and whether a recall is necessary. NHTSA also told the news outlet that the ARC inflators use a different design than those from Takata, instead using some pressurized gas and an ammonium nitrate charge. While the design may be different, the Takata inflators also used ammonium nitrate propellant, which other manufacturers have avoided. We will be watching this situation closely to see what develops. Here's hoping – for our collective safety and sanity – that we won't have to go through another airbag crisis like with the Takata recall.
