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.

Hyundai Le Fil Rouge concept shows the future of brand's design

At this year's Geneva Motor Show, Hyundai revealed a concept called the Le Fil Rouge, which in English means "the common thread." Though the car has an unusual name, it's important for the Hyundai brand because this car represents the future of the company's design. Elements found on this concept will be applied to all future Hyundais, be they sedans, hatchbacks or crossovers, which also partly explains the car's name. Hyundai says the name also comes from how the car builds on Hyundai's past design and is a "reinterpretation" of its 1974 Coupe Concept. We're not so sure about that last part, but we think the Le Fil Rouge is a mighty handsome sedan, and its future production cars should look pretty good. Aside from a "common thread" of design, Hyundai says the car's theme is "sensuous sportiness." That seems to translate into a low-slung, curvy, coupe-like sedan form. At the front, the nose is very low, and it's dominated by a massive version of Hyundai's corporate "cascade" grille. It's actually a bit reminiscent of the recent Lagonda sedan. It appears that the grille contains lighting elements all throughout. It should be easy to translate this design into conventional radiator grilles, huge lights, or simple, blocked off styling motifs for electric vehicles. This low, wide grille leads into a long hood and front fenders with classic rear drive proportions. The hood has two large creases in the middle that lend some aggression to the swoopy shape, and there are two bright metal accent lines that run up the sides and loop up and around the windows back toward the hood. Along the side, we find a bold character line that lines up with the end of the headlight. It trails back along the car and merges with the rear panel that would likely contain the taillights. The roof also has a bit of a fastback look, ending at the trunk lid. It also contains a rear window with a double-bubble shape. It's an elegant, organic car that does some cool things with lines and curves. It will be interesting to see how it translates to production cars.

Hyundai bringing Elantra GT, special edition Veloster to Chicago

Hyundai will be bringing two new products to next week's Chicago Auto Show, a company source confirmed to Autoblog. The first is a freshened version of the Elantra GT – pictured above as a 2014 model – and the other is a special edition of the Veloster hatchback. Our source was mum about specific details, but said that the Elantra GT refresh was simply that – nothing crazy or all-new. In other words, we expect some lightly touched-up styling, and perhaps some improvements to the interior refinement, infotainment and technology, and maybe powertrain. As we reported earlier, the two-door Coupe is no longer part of the Elantra lineup, so these changes might be a way for Hyundai to further differentiate the GT from the sedan. As for that Veloster, it won't be anything revolutionary, either. Hyundai has historically used the Chicago show to debut special editions of the Veloster – take a look at last year's Re:Flex, for example – and we expect the same this time around. Perhaps a new matte paint finish? That's been a popular choice for Veloster Turbo buyers, after all. Whatever may be in store, we'll have the full scoop next week during the Chicago festivities. Stay tuned. Related Video: Featured Gallery 2014 Hyundai Elantra GT View 21 Photos Chicago Auto Show Hyundai Hatchback Economy Cars hyundai elantra gt
