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 sketches out HND-9 luxury sports coupe concept ahead of Seoul

Hyundai has dropped a couple of rendered looks at its forthcoming HND-9 luxury sports coupe concept, which will debut at the 2013 Seoul Motor Show. While full details probably won't be released until then, the Korean automaker has said the butterfly-doored machine will bow with a direct-injection, turbocharged 3.3-liter V6 engine good for around 365 horsepower. The mill is bolted to an eight-speed automatic transmission and puts its grunt to the rear tires. While the doors are pure showcar theater, we dig the Aston-inspired long nose and boisterous rear haunches.
Look for the car to receive an actual introduction on March 28, and while we don't expect to see the HND-9 on showroom floors any time soon, some of the creation's design language may make it to production models. Check out the full press release below.

Hyundai Motor shares slide following U.S. probe of airbag failures

SEOUL — Shares in Hyundai Motor tumbled on Monday on a U.S. probe into why airbags failed to deploy in some of its Sonata sedans, with investors fretting about potential recall costs for the once popular cars. The probe, which follows crashes that reportedly killed four people and left six injured, will review the 2011 Sonata sedan as well as the 2012-2013 Forte made by affiliate Kia Motors, encompassing some 425,000 vehicles. It marks the second investigation by the U.S. National Highway Traffic Safety Administration into the South Korean duo in less than one year, exacerbating headaches for Hyundai which reported in January its worst annual earnings in seven years. Hyundai has issued a recall for more than 150,000 U.S. Sonatas after incidents of non-deployment were linked to electrical overstress in the airbag control unit, but said it did not have a final fix. "What I am concerned about is that the recall will be expanded to other markets," said Ko Tae-bong, an analyst at Hi Investment & Securities. The Sonata and Forte sedans were responsible for driving sales for Hyundai and Kia in key markets in recent years, although they are no longer as popular as they once were. Ko estimated the U.S. recall could cost as much as $575 million if airbags were replaced in 425,000 vehicles under review and the automakers were found responsible for the problem. Hyundai Motor shares tumbled 4.8 percent while Kia Motors lost 3.7 percent. Parts supplier Hyundai Mobis fell 5.4 percent while the broader market was down 0.7 percent. Hyundai declined to comment on whether the recall would be expanded. Kia said it has not confirmed problems with the airbags but added it would "act promptly to conduct a safety recall, if it determines that a recall would be appropriate." The automakers told the South Korean regulator that the Sonata and Forte models sold in the domestic market were not affected, an official at South Korea's transport ministry told Reuters. The U.S. regulator said the airbag control units were built by ZF Friedrichshafen-TRW, a German auto supplier that acquired TRW Automotive in 2015, adding that it would determine if any other manufacturers used similar airbag control units and if they posed a safety risk. The NHTSA also said that electrical overstress appeared to be the root cause in the 2016 recall by Fiat Chrysler America of 1.4 million U.S. vehicles for airbag non-deployments in significant frontal crashes.
