Kia shows off 2 tuned Stingers, modified Cadenza at SEMA

Ascendant Korean automaker Kia is leaving its mark on the SEMA Show in Las Vegas with two versions of its forthcoming 2018 Stinger GT, including the wide-body version developed with West Coast Customs that we previewed recently, and a sumptuous version of its premium sedan it's calling the Cadenza Obsidian. The third model is the Stinger GT Federation, which Kia says marks its foray into offering high-performance aftermarket parts through suppliers in conjunction with a vehicle launch (the production Stinger hits showrooms in December). Kia pairs the GT Federation with Air Design USA performance kits like a rear spoiler, rear diffuser and redesigned hood vents that contrast with the fastback's custom creamy-orange paint. The GT-standard twin-turbo 3.3-liter engine gets an added 15 horsepower, taking it to an estimated 380 hp, thanks to a K&N cold-air intake and a low-restriction quad-tipped Borla exhaust. It also gets Eibach springs, beefier antiroll bars and a reduced ride height, plus staggered 20-inch TSW wheels with Falken tires. Kia teamed with West Coast Customs for both the Stinger GT Wide Body and the Cadenza Obsidian sedan. The latter gets an upscale aesthetic makeover with ultra-dark ceramic window tint, metallic black body paint and copper accents inside and out. It rides on a lowered suspension with stiffened sport springs and custom 20-inch gloss-black Keen wheels with Cosmic Copper trim. Inside, there's hand-stitched suede dashboard top panel, "butter-soft" brown leather seats with suede inserts, and custom brown suede door panels. Oh, and there's a Harmon Kardon 630-watt premium sound system with an integrated subwoofer — perfect for belting out "Let It Go" at full voice during your morning commute. Kia also revealed new details about the Stinger GT Wide Body, which takes its inspiration from grand-touring racing cars of the 1970s. Its suspension has been lowered 1.4 inches up front and 1.2 inches in the rear, and it rides on 21-inch Keen forged wheels fitted with high-performance tires. The body gets wide fenders, a lightweight carbon-fiber aero kit and rear diffuser, plus quad-port exhaust tips. Inside, the makeover features custom blue leather seat piping, a hand-stitched gray leather dash panel, Alcantara-wrapped steering wheel and gloss-black center console trim.

Did a US automaker blow the whistle on Hyundai, Kia fuel economy issue?

In all of the most hotly contested mainstream segments of the motoring universe, the difference of one mile per gallon averaged on a widow sticker can mean the difference between a sale and a walk-off - to say nothing of two or three mpg. So, when Hyundai and Kia were forced to reveal that many of their 40-mpg ratings were actually 38s and 37s, well, it made for big news.
It also, conceivably, made for a competitive disadvantage immediately, when the Korean automakers' products were being shopped versus the guys down the block. And it's that disadvantage that makes a recent story from Automotive News so juicy.
AN is reporting that Margo Oge, former head of the Environmental Protection Agency's Office of Transportation and Air Quality, got a tip in 2010 that Hyundai/Kia were "cheating" to get its impressive fuel economy numbers. The tip, said Oge (who retired from the EPA this past September), came from a senior vice president from a domestic automaker. The source was credible enough for Oge to launch an audit of the Hyundai figures, which ultimately lead to the debacle that we reported on a few months ago, and that the Korean company has been trying to bounce back from ever since.

Hyundai and Kia introduce new predictive transmission tech

Hyundai and Kia have announced that the two have developed a new transmission control system that optimizes shift logic to both improve efficiency and reduce "gear hunting." The system utilizes real-time traffic data, built-in 3D navigation and the same sensors that feed the cars' advanced safety and driver assist tech to proactively choose the right gear — even neutral in some cases — to reduce both fuel consumption and wear-and-tear. The Korean sister brands call it the "Information Communication Technology Connected Shift System," or "ICT" for short, and Hyundai says it delivers not just improved frugality, but a better all-around driving experience. ICT programming allows the transmission control unit to collect and interpret traffic, camera, sensor, navigation route, elevation and topographical data.  "Using all of these inputs, the TCU predicts the optimal shift scenario for real-time driving situations through an artificial intelligence algorithm and shifts the gears accordingly," the announcement said. "For example, when a relatively long slow down is expected and radar detects no speed irregularities with the car ahead, the transmission clutch temporarily switches to neutral mode to improve fuel efficiency." While this sounds like a primarily green play, there are quality-of-life improvements too. For example, ICT can also optimize gear selection and shift points for safer highway merges, effectively implementing the equivalent of a "Sport Mode" driving profile when a little extra punch is called for.  Hyundai says the resulting decrease in shifts was significant; in some test scenarios, such as roads with lots of curves, the number of shifts executed by the transmission was reduced by almost half. As an added bonus, these vehicles also utilized their brakes less often (11%), which would reduce wear (and accompanying maintenance costs) over time.  ICT is somewhat future-proof, too, as it was developed to incorporate vehicle-to-vehicle (V2V) data should such networks improve down the line.  The announcement did not say when the new tech would reach customers, committing only to introducing the technology "on future vehicles." If we're betting, the smart money says it will probably on a new Genesis model and trickle down from there. Related Video:
