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.

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises. You can check out the full press release below. You can also read the full study on the Consumer Reports site, or scroll down for a short video recap.

Hyundai reveals new Sonata Hybrid in Seoul

The wraps are off Hyundai's next-generation Sonata Hybrid after an unveiling in Seoul, South Korea, and the latest model brings an improved powertrain and slight styling tweaks. In the Korean domestic market, the Sonata Hybrid relies upon a 2.0-liter, four-cylinder gas engine producing 154 horsepower and 140 pound-feet of torque with a 51-hp electric motor providing the rest of the thrust. Hyundai isn't revealing net system output at the moment, and it isn't saying whether we will get this powertrain in the US yet. Company spokesperson Jim Trainor tells Autoblog that those details will likely be announced at the model's North American debut at Detroit Auto Show in January. Sales are expected to begin in the spring. In addition to the upgraded engine, there's an improved six-speed automatic that houses most of the hybrid components and uses a new clutch to reduce drag. The switch to an electric oil pump also removes some inefficiencies, and the battery pack underneath the trunk has been enlarged to 1.62 kilowatt hours, up from 1.43 kWh. Despite the capacity increase, Hyundai claims there's 10.5 percent more cargo room back there. The Sonata's design gets a slight rethink to improve fuel economy, too. Up front, the redone nose features a new mesh grille in a more rectilinear frame, and out back, there's a set of unique taillamps, a lip spoiler and a unique rear diffuser to go along with the full underbody cover that only the pavement sees. If anything, the new hybrid model looks more traditional to our eyes than the standard gas-powered Sonata, which comes as something of a surprise, especially as the previous-generation Sonata Hybrid was markedly more futuristic and divisive in its appearance. In any case, we expect the looks to remain largely the same for the US version, which will likely arrive wearing a 2016 model-year designation. All of the upgrades, boost fuel economy to 18.2 kilometers per liter on the Korean cycle, the equivalent of about 42.8 miles per gallon. Comparatively, the current Sonata Hybrid in Korea is rated at 16.8 km/l (39.5 mpg). Hyundai will also make a big expansion to its electrified slate next year. In addition to the standard Sonata Hybrid, a plug-in version will come later in 2015 – the automaker's first. More details will arrive about the model in Detroit.
