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.

2014 Hyundai Tucson gets DI engines, styling tweaks, priced from $21,450*

Despite being overhauled for the 2010 model year, not much attention has been paid to the Hyundai Tucson crossover in recent times. But when its overseas twin, the ix35, received modest updates at this year's Geneva Motor Show, we knew it'd only be a matter of time before the US-spec model was blessed with similar tweaks. So, without further ado, meet the ever-so-slightly enhanced 2014 Tucson.
The most significant mid-cycle change is found under the Tucson's hood, where two new direct-injected four-cylinder powerplants are found. On the base end, there's a brand new 2.0-liter "Nu" inline-four, good for 164 horsepower and 151 pound-feet of torque. These numbers represent a loss of one measly horsepower, but five more foot-pounds of torque. Nothing significant here, and fuel economy is only slightly better - 23/29 miles per gallon city/highway versus the 22/29 rating of the 2013 model. Uplevel Tucson models use a revamped 2.4-liter engine, also featuring direct injection, which produces 182 hp and 177 lb-ft of torque - gains of six hp and nine lb-ft, respectively. That said, fuel economy for the front-wheel-drive, automatic transmission model has actually suffered some - 2013's rating of 21/30/25 mpg (city/highway/combined) has fallen slightly to 21/28/24. Both front- and all-wheel drive are available on all trim levels.
As far as visual enhancements go, the 2014 Tucson now uses projector-beam halogen headlamps up front and LED taillamps out back, and redesigned 17- and 18-inch alloy wheels are fitted, depending on trim level. Inside, two new cabin colors are available - beige and brown - the navigation system has been enhanced with a choice of two touchscreen interfaces, and there are now two-stage reclining rear seats.

Tesla layoffs, new safety mandates, and a bumper crop of V12s! | Autoblog Podcast #830

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd for a gasoline-powered installment. They lead off by diving into the Tesla layoff news from this week before leaving electrification behind for a bit to talk about not one, but two production V12 unveilings. This isn't a drill, folks; Aston Martin and Ferrari are both committed. After that, they touch on the U.S. government announcement that it would mandate automatic emergency braking systems starting in 2029. They finish up the news segment with a chat about Fisker. Poor, poor Fisker. From there, it's on to the road tests. The Autoblog team has been testing out some EVs and both Byron and Greg had some thoughts to share, plus we get a final update from Byron on the long-term Subaru WRX and some notes from both drivers about the updated Range Rover Evoque.  Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.
