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.

Genesis bringing an EV concept and G90 to New York Auto Show

It's official, the entire Hyundai Group has plans for the New York Auto Show. During the Hyundai Sonata press launch in South Korea, design head Luc Donckerwolke told Roadshow "You'll have an electric show car for Genesis." This year will be the charm for Genesis and EVs, after showing the GV80 SUV concept and its hydrogen fuel cell powertrain in 2017, and the electric Essentia coupe concept last year. We will also see the production version of the U.S. market Genesis G90 and its mongo grille. The premium brand's debuts will join the new Sonata sedan and Venue crossover, and an as-yet-unnamed Kia show car expected to be our version of the SP Signature concept potentially called Tusker. Hyundai-Kia isn't getting its electric razzle dazzle ready for New York alone. Auto Express reports the group is working on a new electric car platform to serve the carmaker the same way Volkswagen's MEB architecture serves the German group's brands. At the moment, the only four EVs in the South Korean automaker's range are the Hyundai Kona and Ioniq, and the Kia e-Niro and Soul. They are all built on ICE platforms, the Kona and e-Niro still proving popular enough for this year's planned UK-market production to sell out already. According to a "company insider," the dedicated EV platform is around two years away and will focus on B- and C-segment cars. That's the same year that Genesis is expected to have its EV ready, but unless the luxury arm has plans to dip its grille into C-segment waters, Genesis likely has other EV platform plans. By 2025, Hyundai and Kia have said they'll have 14 EVs in the combined lineup as part of 38 electrified offerings. Whatever's on the way could prove far more radical than today's offerings. Donckerwolke told Auto Express that in order to attract the future EV buyers that aren't necessarily car people, "[You] have to ask whether you want science fiction or whether you want to conform. We can create something that doesn't appeal to someone in the traditional sense." If the head designer gets his way, 3D-printing will help whip up those attractions. Last year's Essentia concept showed off 3D-printed carbon fiber ornament, but the potential goes much further.

The new Hyundai Veloster will have a driver-focused interior

We've had a number of solid glances at the Hyundai Veloster's exterior while testing, but this is our first look at the car's interior. And it's a seriously good look. About the only thing hiding the dashboard is some snazzy zebra-print vinyl wrap. We can tell from these new spy photos that the Veloster's interior is more focused on the driver than other Hyundais. The center stack is canted slightly toward the driver, and it's a bit asymmetrical, favoring the person behind the wheel. At the top of the center stack is a large touch screen that protrudes from the dash, but it looks a bit more integrated than the screen found in the Elantra GT, as it's nestled between two air vents. We have reason to suspect this is a Veloster Turbo model, which may be renamed Veloster Sport to fit nomenclature used on the Elantra line. The steering wheel is leather-wrapped and has a metallic red accent in the bottom spoke, just like the wheel in the Elantra Sport models. The shifter also has an accent in the same red color as the one on the wheel. We doubt this could be a Veloster N, though, as the seats don't seem aggressive enough, and there don't appear to be any accents in the performance sub-brand's trademark light blue. We expect to see this interior fully revealed, along with the rest of the Veloster lineup, by the end of the year. It will be available in three versions, an entry-level model, a peppier Turbo or Sport version with the outgoing model's center exhaust and more aggressive looks, and a high-performance N model that will probably use the Elantra i30 N's 271-horsepower turbo engine. The Veloster N will also have the most aggressive looks, featuring a large rear wing. Related Video:
