Hyundai twin-charged 1.8L GDCI gas engine expected to be more efficient than 2.0L diesel

Despite the growing trend of automakers offering diesel-powered or electrified powertrains, there's still a whole lot that can be done with the good-old gasoline internal combustion engine. And at Hyundai, that's exactly what's being worked on - new gasoline engine technologies that improve both performance and efficiency. During an event at the automaker's technical center in Superior Township, MI on Friday, Hyundai gave Autoblog a glimpse into the future, offering up preliminary details on its new GDCI (Gasoline Direct-Injection Compression) engine - something that will be heading to production soon.
Hyundai's main goal with this GDCI engine is to "achieve diesel levels of fuel efficiency with conventional gasoline," according to Nayan Engineer (yes, his last name is Engineer), one of Hyundai's powertrain gurus. What's more, Engineer says the GDCI engine will offer "equal to better performance than conventional gasoline engines" and will have a "lower system cost [than] diesel engines."
Hyundai expects a 1.8-liter GDCI engine to be more efficient than a comparable 2.0-liter diesel engine with similar performance.

Hyundai's zombie obsession is just good business

In case you somehow missed it, Hyundai has enjoyed a long and fruitful relationship with The Walking Dead, the critically acclaimed zombie apocalypse show that entertains the masses while they're waiting for the next season of Game of Thrones. Fans of the show will recognize Rick, Michonne, Carol, Maggie and Glenn's mint green Hyundai Tucson, a staple vehicle for the crew of survivors, but the relationship between manufacturer and show goes far beyond that. There's a whole line of Zombie Survival Machines, as well as a special-edition production model (shown above). Heck, even Hyundai's post-LA Auto Show party featured actors staggering about as startlingly realistic walkers (TWD's name for zombies).
So what is it about the dead that quickens the pulse of Hyundai's marketing department? Ward's Auto has a great interview with Steve Shannon, the brand's US vice president of marketing. In it, Shannon describes the sudden nature of the tie-in between the show and the automaker, while describing how the company's corporate overlords in South Korea saw the results of the deal. It's an interesting insight into automotive product placement, as well as Hyundai's marketing philosophy and plans for the future (spoiler alert: the Tucson, which has had a role in the show for several seasons, was seemingly abandoned at the end of season four).

Hyundai, Kia recall 270,000 cold-weather state vehicles over rust

Hyundai has announced plans to recall 240,000 Sonata and Azera models registered in the northern United States over corrosion caused by the use of road salt. Exposure to the salt can cause rust to form (we know, basic chemistry here), and that the corrosion can change the alignment of the rear wheels, according to Reuters.
Sonatas from the 2006 to 2010 model years, built between March 1, 2005 and January 21, 2010, and Azeras from the 2006 to 2011 model years, built between September 27, 2005 and November 22, 2010, are covered only if they were registered in the following states: Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and Washington, DC. So basically, every state from the Midwest, to the central Atlantic coast, to New England. It is unclear exactly how many Sonatas or Azeras make up the 240,000 total number.
Hyundai is also recalling 20,300 of its 2013 Santa Fe Sports, while sister company Kia is recalling 9,345 2014 Sorentos. This second recall only covers Santa Fe Sport and Sorento models with the base, 2.4-liter engine and front-wheel drive. Apparently, the front axle driveshaft can develop cracks and separate.
