Hyundai reveals all-new Sonata in South Korea

We've seen the spy shots. We've seen the teasers. We've even seen the finished product uncovered in its home market. But now Hyundai has officially taken the wraps off its new Sonata, consistently one of its top sellers in North America that was surpassed only recently in the sales charts by the smaller, cheaper and slightly newer Elantra. It's Hyundai's challenger to the likes of the Toyota Camry, Honda Accord, Nissan Altima, Ford Fusion et al, which makes it a vital debut not only for Hyundai but for anyone in the market for a mid-size family sedan - and that's one of the biggest markets of all.
Set to be revealed at the New York Auto Show in a matter of mere weeks, the all-new 2015 Hyundai Sonata you see here is the latest representation of a more toned-down family design language which Hyundai calls Fluidic Sculpture 2.0, following the lead set by the new Genesis and away from the swoopy and sharply creased styling of the successful but stylistically divisive model it replaces. A good inch longer and wider than the outgoing Sonata, the new model is also over a third more rigid, thanks in no small part to the use of high-strength steel that now composes over half of the body's construction.

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 rehires R&D president let go over quality issues

Last November, Hyundai announced the resignations of research and development president Kwon Moon-sik and two other R&D executives. At that time, it was said that the executives wished to "take responsibility for a series of quality issues" at the Korean automaker. Kwon Moon-sik had only been in the position for a year, but some of the quality issues thought to have caused the resignations included recalls of the Genesis and other sedans around the world, along with the company's much-publicized fuel economy overstatement controversy - both of which dealt with matters that transpired before Moon-sik took his position. In its statement at the time, Hyundai said, "The latest personnel change shows our firm commitment to quality management and reaffirms our will to continuously improve R&D competitiveness."
Three months later, Reuters is reporting that Moon-sik is back with the company, a statement announcing the rehire saying, "Given his expertise, experience and leadership skills, we reinstated president Kwon to enhance quality and R&D capability from scratch." Company chairman Chung Mong-koo is said to have a reputation for firing then rehiring workers, and it's possible this rehire is especially timely because Hyundai will bring its new Sonata to market this year and likely wants its experienced R&D captain at the wheel.
The man who had taken Moon-sik's position has returned to his previous post as head of powertrain development. However, in another surprise resignation, the head of Hyundai's design center, Oh Sug-geun, has left the company for "personal reasons." He has been replaced by Lee Byung-seob, who moves up from his position as head of exterior design.
