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.

Kia unveils K4 sedan concept in China

Among the dozens of foreign automakers eager to showcase their wares to the Chinese market, Kia arrived at the Beijing Motor Show with the new K4. Though technically categorized as a "concept," the K4 previews a sedan which Kia intends to launch in China later this year.
The K4 is a midsize sedan measuring 186 inches long and riding on a 106-inch wheelbase that makes it bigger than the Forte (sold in the Far East as the K3) and just a few inches shorter than the Optima (aka K5). The form is draped in familiar Kia-style bodywork, with a high trunk and low nose to give it a wedge shape and a familiar if somewhat new take on the headlights and grille seen on other new models from the Korean automaker.
Power comes from a 1.6-liter turbo four (smaller than the engines available in the Optima/K5) mated to a seven-speed DCT. Kia has also fitted the K4 concept with push-button ignition, UVO infotainment system, rear-view camera, six airbags and stability management. In short, everything you'd expect from the latest product of a global automaker.

Next-gen Kia Optima previewed for New York Auto Show

To say the Optima is a vital product for Kia would be an understatement. In fact, the Korean automaker reports that the sedan has been its best-selling model in America for three years running. Replacing it with an all-new model, then, would be a big move for Kia, and that's exactly what it's gearing up to do. The all-new Optima is previewed here in a pair of teaser renderings, and the car is set to debut at the New York Auto Show. Though Kia has given us little in the way of information to accompany the drawings, it's clear that the design has borrowed heavily from the Sportspace concept that debuted in Geneva earlier this month – albeit in production form, and with a trunk instead of an extended roofline. The outgoing Optima was introduced five years ago and is built at plants around the world for local consumption, including in Georgia for the North American market. This will be the fourth iteration of the breed. KIA TO UNVEIL ALL-NEW OPTIMA AT NEW YORK AUTO SHOW Following its 2010 debut at the New York International Auto Show, the Optima became a catalyst for Kia Motors' tremendous growth and has been the brand's best-selling vehicle in the U.S. for three years running. Now, five years later, Kia will return to New York on Wednesday, April 1, for the world debut of the passionately designed and obsessively crafted all-new version of its popular midsize sedan.
