Hyundai, Kia to put solar panels on vehicle roofs

Hyundai Motor Group said Wednesday that future Hyundai and Kia models will be equipped with solar panels capable of generating electricity as a way to increase fuel-efficiency and range and lower CO2 emissions. Hyundai says the solar panels will feature in the rooftops or hoods of select vehicles "after 2019" and will supplement traditional internal combustion, hybrid and battery-electric vehicles. The parent group said it's developing three different types of solar roof charging systems comprised of a solar panel, controller and battery. The first generation will be a silicon solar panel system mounted to the rooftops of hybrid models and capable of charging 30 to 60 percent of the battery per day, depending on weather conditions and other factors, starting as early as 2020. The second generation involves a semi-transparent solar roof system applied to a panoramic sunroof and capable of charging an electric-vehicle battery or a battery mounted on a gasoline engine. Hyundai says the latter configuration will help it increase vehicle exports, since solar-equipped ICE vehicles will be able to adhere to regulations limiting CO2 emissions. A third-generation system is being tested right now. It will add solar production capability in the hood and roof of EVs – but the companies don't provide more detail than that at this moment. "In the future, various types of electricity-generating technologies, including the solar charging system, will be connected to vehicles," said Jeong-Gil Park, executive vice president of engineering design at Hyundai Motor Group. "This will enable them to develop from a passive device that consumes energy to a solution that actively generates energy. The paradigm of the vehicle owner will shift from that of a consumer to an energy prosumer." To date, solar vehicle charging technology has mostly been for light-duty tasks, like cooling off the interior or trickle-charging a conventional battery, such as the system offered in the previous Nissan Leaf. Systems that do more than this have typically come with a very steep pricetag for modest capabilities. Panasonic has developed a 180-watt solar roof available for the Japanese version of the Toyota Prius Prime plug-in hybrid that is capable of adding up to 3.7 miles of range per day – at an unspecified (as of this writing) but undoubtedly high cost. Elon Musk, unsurprisingly, has also discussed making a solar roof optional for the Tesla Model 3.

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.'

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
