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.

Who can really claim first mass-produced fuel cell vehicle delivery in US?

Last month, Hyundai said that the initial deliveries of the Tucson Fuel Cell vehicles in California meant that, "For the first time, retail consumers can now put a mass-produced, federally-certified hydrogen fuel cell vehicle in their driveways." But try telling that to Jon Spallino. In 2005, Honda leased a hydrogen fuel cell FCX, a small hatchback, to the Spallino family (as far as we know, he parked it in his driveway). The company did the same thing again in 2008 with the FCX Clarity, a sleek new design based on the FCX Concept, and others signed for the H2 ride as well, including celebrities. No matter how you slice it, Honda has been in the fuel cell delivery market for almost a decade now. Just look at this. Or this. Or this. Oh, and other automakers (General Motors in Project Driveway in 2006 and Mercdes-Benz with the F-Cell in 2010, for example) have delivered fuel cell vehicles in the US as part of short-term test programs. But let's get back to Hyundai's claim. There's little question that the first delivery of a "fuel cell vehicle for the US market" has already taken place (and they were federally certified, too), which means that the debate revolves around the definition of mass-produced and whether "mass production" is about a number or about the process? Let's investigate below. First, lets review Honda's bona fides. We can start with the official version of Honda's fuel cell history, which is missing the pertinent detail that Honda build the Clarity on a dedicated assembly line and established a small network of three dealerships to lease the FCX Clarity in 2008. All of the FCX Clarity vehicles in customer hands in the US were leased through these dealerships. Sure, Honda started with hand-built stacks in its hydrogen vehicles, but went to automated control of some parts and components with series production. "It is good to see others doing today what we've been doing since 2008" – Steve Ellis, Honda Or, as Honda's Steve Elllis put it to AutoblogGreen regarding Hyundai's fuel cell deliveries: "This was exactly as prescribed by the creation of the California Fuel Cell Partnership. It's the very essence of 'co-op-itition.' We at Honda, as do many others, continue to push forward on many technologies, both the battery and the fuel cell. And society is the beneficiary." Then he added, "It is good to see others doing today what we've been doing since 2008." Now, how does Hyundai compare?

Next Hyundai Elantra GT hatchback previewed by i30 teaser

The Elantra GT hatchback looked a bit neglected after its sedan sibling was introduced last year. That said, the Elantra hatchbacks have historically been released after the sedan, and usually had significant differences between the two body styles. Based on this latest teaser from Hyundai, the hatchback will continue its unique streak. The teaser is officially for the European i30, but the i30 and Elantra hatchbacks have been the same vehicles since the late 2000s. There's also no sign of the American version being dropped or deviating from its European twin, so it seems a safe bet that this newest i30 will come here with the Elantra name. Hyundai does make it clear that this car was made with Europe in mind though, since both the press release and video tout the fact that all of the styling and development work was done in Europe. Peter Schreyer, lead designer for the Hyundai group, says this car is "the next step to how Hyundai design should be." So look for key design elements like the "cascading grille" to appear in future Hyundai vehicles. Speaking of design elements, we can actually spot a decent amount of them in the teaser image and video. The grille extends down the front of the bumper in a similar fashion to the sedan. Overall, the shape of the car looks more formal and upright than the steeply raked design of the current model. In addition, the sheet metal appears to be much less busy, with far fewer swoops and lines. The car will be fully revealed on September 7 just before the Paris Motor Show. Related Video:
