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.

Second-generation Hyundai Veloster spied with same asymmetric doors

Until we saw these photos, the future of the Veloster didn't look especially bright. It's entering its fifth year on sale with no major updates, and no announcements for a replacement. It also was killed in the UK three years ago when it wasn't selling well. However, these photos show that Hyundai hasn't given up on it. At first glance, it looks very much like the current model, but closer inspection reveals some differences. Up front, the hood looks lower, and it tapers down to what seems to be an exaggerated version of the "cascade grille" Hyundai has implemented on the Elantra GT, and new Sonata. The headlights look slimmer, and there seem to be fewer busy, "quirky" lines. Moving backward, we find the same asymmetric door layout consisting of one door on the left, and two on the right. On the right side, the rear door handle is still tucked in the corner of the window. The glass area on the right also appears a bit larger thanks to a lower edge that stays lower for longer. At the rear, the camouflage is at its heaviest, but interesting details still show through. The rearmost glass seems to be more steeply raked. We can't tell if there's still glass on the top of the hatch, but considering the evolutionary nature of this car's design, we would expect the same amount of hatch glass. The taillights have adopted the slim and wide look of other recent Hyundai's. The center-exit exhaust remains, too, but it looks a bit smaller, and no longer has an obvious split in the middle. On either side of the bumper are auxiliary vents, likely fake. Besides the low sales and limited updates, another reason we questioned the future of the Veloster was its unremarkable driving dynamics. While forgivable in the base model, it was an issue on the Turbo, which simply wasn't fun enough to recommend over competitors. We're glad to see Hyundai will give it another shot, though, since the world can always use more quirky and interesting automobiles. Hopefully this next one will drive better. And who knows, it might even spawn a crazy mid-engine, rear-drive version. Related Video:

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum
