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.'

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 CEO touts new EV platform with mention of a pickup

A couple of years ago, one of the prominent concerns about a saturated EV auto-scape was how carmakers would accentuate brand differences among vehicles converging on a frightening sameness. The cars wouldn't make any noise, they would all emphasize aerodynamics, and they would all basically ride on a battery pancake. So far, the fears have been avoided; a Volvo XC40 Recharge won't be confused for a Ford Mustang Mach-E, for instance, and the Ford won't be confused for a Tesla Model Y. Not only that, but automakers are developing platform strategies that heighten the sameness among vehicle architectures because the architecture is where the expenditure and the profit are greatest. Hyundai's the latest to outline its plans for investors. And part of Hyundai's plan could include adding a full-size electric pickup to the range. The mid- to long-term roadmap is called the Hyundai Motor Way, recently revised with higher targets thanks to the swift uptick in EV sales globally. Business Korea wrote Hyundai Motor Group (HMG includes Kia and Genesis) sold 510,000 battery-electric vehicles in 2022. The conglomerate says it now plans to sell two million EVs annually by 2030, up from a previous estimate of 1.87 million.      The platform that will help make this possible is called eM, an evolution of the current Electric Global Modular Platform (e-GMP) platform under HMG's current EVs. The eM architecture's been rumored to launch under a Kia sedan that might be a spiritual successor to the Stinger. So far, eM is planned for 13 models across the HMG portfolio, using the Integrated Modular Architecture (IMA) that can plug-and-play with more than 80 common modules serving different vehicle segments and sizes. HMG president and CEO Jaehoon Chang said, "In the second-generation platform, the scope of vehicle development extends beyond the mid-sized SUVs covered by the current E-GMP system. It encompasses nearly all vehicle classes, ranging from small and large SUVs to pickup trucks, along with the flagship models of the Genesis brand." Sure, Chang could have been merely noting the eM's potential use cases when he mentioned "pickup trucks." That's not how observers are reading the line. At Kia's investor day last year, the brand said it planned two electric pickups. There have already been reports that Kia's working on a body-on-frame pickup for the Australian market, perhaps called Tasman, utilizing gas and electric powertrains.
