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.

2013 Hyundai Veloster Turbo: February 2013

I just couldn't bring myself to lead this post with the image you see on the right. The winter months have not been kind to our matte gray 2013 Hyundai Veloster Turbo, and since you can't just run the thing through your local car wash, our oddly shaped little hatchback has spent more days dirty than clean. It breaks my fleet manager heart to see one of our test cars covered in schmutz so frequently, but let's be honest - the last thing anyone wants to do when it's 12 degrees Fahrenheit outside is play with a hose and spend a good amount of time hand-washing a car.
Moral of the story: If you live in a cold-weather state where you expect to get regular doses of the white stuff, matte paint probably isn't for you. Not to worry, though, as the Veloster Turbo is offered in plenty of pretty, car wash-friendly colors.
We'll have a lot more to talk about regarding the Veloster's cleanability in forthcoming updates, and we're even planning a trip to the Dr. Beasley's office - the company that created the special matte paint detailing kit for the Hyundai - to have their experts show us how it's done. For now, let's spend some time talking about what we've learned about the turbocharged hatch during its honeymoon phase here in the Autoblog Garage.

EPA says it will more closely monitor fuel economy claims from automakers

The unintended acceleration brouhaha at Toyota led to the National Highway Transportation Safety Administration tightening the vise on recall procedures. Likewise, the fuel economy kerfuffle that blew up with Hyundai and Kia's admission of overstated fuel mileage claims could lead to the Environmental Protection Agency policing automaker assertions by performing more audits.
At least, that's what a senior engineer with the government agency said while in Michigan giving a talk, according to a report in Automotive News. What that actually means, however, is still in question. Just ten to 15 percent of new vehicles - something like 150 to 200 cars per year - are rested by the EPA to verify automaker numbers. The EPA's own tests include a "fudge factor" to adjust lab mileage for real-world mileage, and the agency still relies on automakers to submit data for tests that it doesn't have the facilities to perform. How much more auditing can the EPA really expect to do, or perhaps a more relevant question would be how much more accurate could the EPA's audits become?
The price of gasoline, the psychological importance of 40 miles per gallon to a frugal car buyer, an automaker wanting to further justify the price premium of a hybrid, all of these things contribute to fuel economy numbers that insist on creeping upward. Perhaps the senior engineer encapsulated the whole situation best when he said, "Everybody wants a label that tells you exactly what you're going to get, but obviously that's not possible. A good general rule of thumb is that real-world fuel economy is about 20 percent lower than the lab numbers." If the lesson isn't exactly 'buyer beware,' it's at least 'buyer be wary.'
