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.

Behind the scenes of our subcompact crossover comparison

The cameras had been set up for almost an hour, and now, the living room filled with the sweetness of freshly brewed blonde roast. The late-summer sun had just started peaking over towering maples. In a week the colors will start changing, the inevitable sign of the coming gray skies and snow. Half past eight, the editors arrived. The Scandinavian inspired house that served as the headquarters for our subcompact crossover comparison couldn’t accommodate all seven of us, so they had stayed at a turn of the century farmhouse down the road. While geese, chickens, cats and sheep made for an authentic Northern Michigan farm experience, ingredients for a good nightÂ’s sleep they were not. Within minutes Red Bulls cracked open and short, cocoa-colored mugs appeared, filled with a variety of caffeinated beverages.  “I thought we were gonna have fried eggs,” Editor-in-Chief Greg Migliore said, smiling, before refusing a muffin. Associate Producer Alex Malburg ran from camera to camera, adjusting focus and exposure, trying to keep up with the ever-changing light, which poured into the room faster each minute.  “I was promised food. IÂ’m not filming.” Consumer Editor Jeremy KorzeniewskiÂ’s sarcasm thinly veiled his true feelings. To keep the group content I promised a craft-services buffet next time.  For the second time, we shot our comparison just outside of Traverse City. While we took advantage of a local off-road park for the first, this round proved a bit more tame, utilizing the hilly, winding, wine-country roads that define the region.  An air of nervousness could be detected. Only one person knew the outcome of our test, Senior Green Editor John Beltz Snyder. I found myself both impressed and surprised he had kept this secret overnight, though I came to find out later that he revealed the winner to Producer Amr Sayour on the drive to dinner the evening before.  The cameras started rolling, the audio recording, but the caffeine hadnÂ’t yet entered the bloodstream, with one exception. Associate Editor Joel Stocksdale sipped his lime green Mountain Dew. That seemed to be working, as he passionately laid out his argument for the Kia Soul and his preference for winter tires over all-wheel drive. From behind the camera I silently disagreed with him. “No one buys winter tires,” Jeremy argued. As we consumed more coffee, the sun came up, and so did the energy of the debate.

Best 3rd Row SUVs of 2024

If you plan on using a vehicle's third row a lot, let us at least make the suggestion that a minivan would be a smarter bet than anything you're going to see on this list of best three-row SUVs. Their third rows are bigger, more comfortable and easier to get to. The kids will definitely be happier. Here are our two top choices.  OK, now that that's out of the way, we totally get why minivans are totally depressing and that if the kids want to be happier, they can buy their own darn vehicle. You're buying, you're driving, you're being seen in it and you'd rather have a three-row SUV. Fair enough. Luckily, there are more choices than ever and they're really good. The best do a particularly good job of being family friendly without looking like a drab transportation appliance, although really, you can't go wrong with any of the mainstream three-row SUVs. Now, some of the luxury choices are a bit suspect, including those that are otherwise very appealing but have cramped third-row seats (the Genesis GV80 comes to mind). We're focusing on three-row SUVs here, so having a usable third row is a must.   In this list, we have broken things down into four sub-categories: Best Three-Row Crossover |  Best Full-size Three-Row SUV Best Luxury Three-Row SUV |  Best Flagship Luxury Three-Row SUV Note that we define crossovers as SUVs since most buyers use the terms interchangeably, but acknowledge that "crossover" is literally a vehicle with a car-like unibody structure as opposed to the truck-like, body-on-frame construction that traditionally has defined "SUV." In other words, we consider all crossovers SUVs, but not all SUVs are crossovers (specifically those in the full-size segment and some in the flagship luxury segment). Best Three-Row Crossover SUVs of 2024 2024 Honda Pilot Why it stands out: Exceptional storage and cargo space; unique second-row functionality; refined ride; versatile and capable TrailSport; advanced AWDCould be better: Subpar acceleration with lackadaisical transmission and engine response; so-so driver assistance tech Read our full 2024 Honda Pilot Review The Honda Pilot was completely redesigned for 2023. It maintains its predecessor's family friendly packaging and overall focus, but it has injected a welcome sense of style (especially in the TrailSport pictured above) that makes it stand out much better from the big crossover crowd.
