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 to recall 27,500 Genesis sedans over brake issue

Following an investigation launched by the National Highway Traffic Safety Administration earlier this week, Hyundai will reportedly recall 27,500 Genesis sedans due to braking problems. Roughly 40,000 Genesis sedans from the 2009 model year were originally under investigation, but this official recall affects vehicles from 2009 to 2012.
A Hyundai spokesperson told The New York Times that brake fluid may cause the brake control unit valves to corrode, which reduces braking power. Affected cars will have their brake fluid replaced, and if necessary, will have the control unit replaced, as well.
The original NHTSA investigation was launched after the government agency received 23 complaints from owners citing reduced braking power and increased pedal travel. One incident reportedly resulted in a crash, while another caused a driver to lose control of the car. NHTSA has not officially announced the recall as of this writing.

2015 Hyundai Genesis appears uncovered [UPDATE]

Hyundai gave us a tease of its second-gen Genesis sedan courtesy of the HCD-14 Genesis Concept displayed at this year's Detroit Auto Show, and while we've seen numerous spy shots of the car testing since (both on and off the track), all were heavily camouflaged. That all changed today when the South Korean site bobaedream.co.kr posted an image of the new luxury sedan sitting out completely uncovered (click the image to enlarge).
While we can't see much more than the face of the new Genesis sedan, it does appear to be a striking improvement over the current car that debuted back in 2008. The jutting, upright grille is very similar in appearance to the HCD-14 Concept, while the headlights and fascia look like a combination of Mercedes S-Class and E-Class. The body creasing isn't as dramatic as the concept, but the roofline and glasshouse look to be almost identical to the show car. Based on how finished the car looks in this picture, our guess is that we could see Hyundai's new Genesis at an upcoming auto show like LA or Detroit.
UPDATE: Per the request of the individual pictured next to the Hyundai Genesis in the original photo that spurred this story, we have removed said image from the post. You can still see the new Genesis here at the source, for the moment.
