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.

Hyundai CVVD engine brings another dimension to valve timing

A new technology from Hyundai Motor Group places another marker on the march to more efficient internal combustion engines. Called Continuously Variable Valve Duration, the innovation permits two options for how long the intake valves remain open during the combustion cycle. The feature adds a third take on valve chicanery, atop variable valve timing that changes when valves open, and variable valve lift that changes how far valves open. Hyundai says the feature returns a 4% improvement in performance, a 5% increase in fuel economy, and lowers emissions by 12%. Hyundai applied for two patents on the valvetrain process in South Korea in 2011 and again in 2015. The altered valve duration in this latest iteration is made possible by two movable arms inside the camshaft. Each arm is anchored at its base to a pin at the center of the camshaft, while the end of each arm extends toward the edge of the camshaft. Changing the position of the pin in the center of the camshaft changes the angle of the arms relative to one another, which moves the camshaft along its mounting rod. Voila, a new intake cam profile that either lengthens or shortens valve overlap.   During low-speed spells at low load, CVVD opens the intake valve from the middle to the end of compression stroke. The weaker detonation isn't a factor at low load, and the reduced friction during compression improves fuel economy. During heavy engine loads, the intake valve closes at the beginning of the compression stroke to maximize the amount of air mixed for detonation, boosting torque. Four additional features enhance the benefits of CVVD. A more powerful direct injection system increases fuel spray pressure from 250 bar to 350 bar. Hyundai doesn't go into details on its Integrated Thermal Management System, but says the ITMS "quickly heats or cools the engine to the optimal temperature." Low-friction components lower overall engine friction by 34 percent. And a low-pressure exhaust gas recirculation layout diverts low-pressure exhaust gas from the traditional EGR route to the turbocharger compressor under high load for better fuel efficiency.   The first engine to boast the new tech is the Smartstream G1.6 T-GDi four-cylinder, which produces 180 horsepower and 195 pound-feet of torque. It will appear in the 2020 Hyundai Sonata Turbo going on sale in South Korea later this year.

We visit Hyundai's Nurburgring test center

Understanding the achievement and the message of Hyundai Motor Group having a European Technical Center at the Nurburgring might be easier if we look at what Hyundai has done in the US. In 1985 Hyundai Motor America set up shop in California. The first car sold here was the 1986 Excel, a rebodied Mitsubishi Mirage with a Hyundai interior treatment. This was the first Mirage, which also served as the Chrysler Colt in hatchback form and circled back as the Mitsubishi Precis so Mitsu could get around Japanese automakers' voluntary export quotas of the time. The Excel made such an impression on reviewers and buyers that in Car and Driver's 1986 review they wrote that "'astounding' is not too strong word" to describe the company's progress, and said, "Our guess is that Hyundai will be a major force in the US car market almost from the moment it opens its doors." Hyundai sold 168,882 Excels in the US in its first year, back when the Ford F-Series led all comers with 544,969 sales. That's what happened. The company sold 168,882 Excels in the US in its first year, back when the Ford F-Series led all comers with 544,969 sales, the Chevrolet Celebrity came second of all vehicles with 408,946 sales, the Honda Accord seventh with 325,004 sales. The Excel sold even better the following year, and the year after that. Three years on, buyers began to discover that one of the things the Excel did best was disintegrate. It's been called "fantastically crappy," Popular Mechanics would later say the Excel "deserved to fail," and they decomposed so thoroughly that you'll have a hard time finding one in any junkyard. Buyers got so allergic to the Flying H badge that sales declined for ten consecutive years. By 1999, when Hyundai's model range was four times larger than it had been in 1986 – Accent, Elantra, Sonata, Tiburon – the brand sold just 90,217 cars in the US. Two important things happened around that nadir. In 1998, as a way of reassuring potential customers, Hyundai became the first automaker to introduce a 10-year, 100,000-mile warranty. In 1999, Mong-Koo Chung became the CEO of Hyundai Motor Company, promoted from 11 years as CEO of Hyundai Motor Service, a role that put him in charge of global warranty claims. Having spent all those years of his life wading through that carnage, he swore when he took the top spot that he'd get the situation fixed. In 2014 the JD Power Initial Quality Survey ranked Hyundai the leading non-premium brand.
