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 teases HCD-14 concept ahead of Detroit debut

As is the case ahead of any major auto show, we're expecting to see a plethora of leaked information or teased images before next week's Detroit Auto Show, and Hyundai is already giving us something pretty exciting to look forward to. Shown above in this shadowy teaser is the HCD-14 Concept, which the automakers says gives a "glimpse into future Hyundai premium vehicle design."
Based on the shape of the headlights and the sloping roofline, this image matches up quite well with some spy shots we saw last month reported to be the next-generation Genesis sedan. It also bears more than just a striking resemblance to Kia's new flagship sedan, the Quoris. Either way, we approve. Aside from the car's appearance, Hyundai is also promising "advanced 3-D gesture-based technology controls" inside the car as well as a sportier driving dynamic.
This is all we have to work with right now, but we'll have all the coverage for this new Hyundai and everything else on display at the auto show kicking off a week from today.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
