2019 Hyundai Kona Electric range officially EPA-rated at 258 miles

Since the Hyundai Kona Electric was first revealed at the Geneva Motor Show earlier this year, we've been gradually getting closer to learning the exact electric range for the American car. Finally, after a few estimates, the EPA has released its official rating of 258 miles. That's 8 miles higher than Hyundai's estimate for the U.S. car, given a few months ago. This also puts Hyundai in a strong position against the current crop of electric car competition. While the funky Kona does come up short of the long-range, 310-mile Tesla Model 3, that particular Model 3 costs over $40,000, even with the tax incentive that's not long for this world. The Kona Electric will likely start at a lower price point comparable with the fabled short-range, 220-mile Model 3, which is also 38 miles short of the Kona's range. As such, the Chevy Bolt EV is likely the closest competitor, offering 238 miles, 20 short of the Hyundai, and a price of about $30,000, though that's also with a tax credit that will probably be ending soon for Chevrolet. The 2019 Hyundai Kona Electric goes on sale in California and select other states toward the end of this year. More states will be added early next year. This will be a disadvantage for Hyundai, since both the Model 3 and Bolt EV are currently available nationwide. Related Video:

Hyundai Tucson Fuel Cell CUV deliveries running behind schedule

Things are running a little bit behind on Hyundai's hydrogen-powered Tucson Fuel Cell CUV program in the US. The last time we checked in with the South Korean automaker's H2 project, we heard that the first deliveries were supposed to happen by the end of March. Speaking with Hyundai's Kevin Lee at the Hyundai booth at the SAE World Congress this week, we learned that deliveries are now going to happen closer to a month from now. Globally, there are roughly 70-100 of these hydrogen CUVs running in customer hands today. Lee told AutoblogGreen that the first US-bound units will be shipped from South Korea at the end of April or beginning of May but there is no actual date set for the first customer delivery. He said he expects 100 or fewer H2 powered Tucson CUVs to be operating in the US by the end of this year, all of them in Southern California. He said the customers in this first batch are being selected based on the location of the nearest hydrogen fuel station. While the number of stations is small today, more are on the way. Globally, there are roughly 70-100 of these hydrogen-powered CUVs (also known as the ix35) running in customer hands today, in places like South Korea, Germany, Norway, Austria and Italy. Some H2 stations charge Hyundai a flat rate per fill while others charge the automaker a general station maintenance fee. In the US, the Tucson Fuel Cell CUV leases for $499 a month (with $2,999 down) for 36 months, and comes with unlimited hydrogen refueling as well as Hyundai's Valet Maintenance. Lee told us that one reason for the "free" hydrogen is that even the small number of public hydrogen stations out there (nine in SoCal) does not have a cohesive set of rules for how to sell H2 to the public. The stations are not yet certified to charge customers based on dollar per kilogram in California, Lee said, since that regulation has not yet been set by the Division of Measurement Standards (DMS). Currently, "each station is different," he said, with some charging Hyundai a flat rate per fill and others charging the automaker a general station maintenance fee. This situation will likely change by the end of the year, he said. Lee said Hyundai is already busy working on the next-gen fuel cell vehicles and trying to reduce costs but was not able to share any details.

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.
