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 releases series of KDM Genesis videos

We had plenty of nice things to say about the sleek, new Hyundai Genesis Sedan when we drove the Korean domestic market version late last month. And while we're still waiting to find out just when the new rear-driver will arrive in the US market, Hyundai's home-market operations have released a series of videos on the new sedan.
Now, unfortunately, all the videos are in Korean. While we haven't the foggiest idea of what they're actually saying, the eight videos in the series give a great look at the new Genesis Sedan in motion, as well as showing off some of the development process behind the newest member of the Hyundai family.
We've embedded all eight videos below for your viewing pleasure. Have a look below.

2018 Hyundai Elantra Buying Guide | Questions answered about a popular compact sedan

The Hyundai Elantra is a sensible small sedan that scores big when it comes to overall value and safety. But the 2018 Elantra won't get any pulses racing when it comes to driving excitement, or a look-at-me exterior. Rivals like the Honda Civic and Mazda3 are simply more fun to drive, and the Civic in particular stands out with racy looks, but it's worth noting that the newer Elantra has made great strides in refinement and comfort compared to its predecessor. Hyundai also offers the Elantra GT, a handy – and handsome – four-door hatchback. Since it was significantly updated for the 2017 model year, the 2018 Elantra receives only minor changes, focused primarily on available options on specific trim levels. Here you'll find all the information needed to make an educated buying decision if you're considering a 2018 Hyundai Elantra, including safety and reliability ratings, engine specs, horsepower, fuel economy ratings and pricing. We'll also summarize what Autoblog's professional auto reviewers think of the Elantra. Is the 2018 Hyundai Elantra Safe? The National Highway Traffic Safety Administration gives the 2018 Hyundai Elantra an overall crash-test rating of four stars. In every crash test, the latest Elantra scored a four-star rating, though the NHTSA results do mention that rear passenger safety was compromised in the side barrier crash test. According to the NHTSA, this "simulates an intersection collision between a standing vehicle and moving barrier at 38.5 mph." During this test, the interior door panel intruded into the passenger compartment, raising the risk that a rear occupant could be injured – though the four-star rating remained. The Insurance Institute for Highway Safety, which provides ratings for new vehicles based on its own comprehensive crash tests, has given the 2018 Hyundai Elantra its "Top Safety Pick+" award, the highest rating available. The Elantra earned a "superior" rating for front crash prevention, along with "good" ratings in all but one of the IIHS' crash tests. Front passenger protection in the notoriously demanding small overlap test was deemed "acceptable." The Elantra also scored an "acceptable" rating for its LATCH anchors for child seats. Headlight performance, meanwhile, received a "good" rating.
