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.

Less stressful than a taxi: We ride in Hyundai's Autonomous Ioniq Electric

The day after California told Uber to halt the testing of its driverless cars, Hyundai gave us a brief ride in an autonomous Ioniq Electric. The trip was mostly uneventful — our driver/engineer didn't hit anyone, and, unlike Uber's, Hyundai's car didn't run any red lights. You may think that's faint praise, but at the speed of advancement we take nothing for granted. More than once during our ride around a pre-mapped, all-right-turn route in Las Vegas, the Ioniq had to sort things out for itself, and the longer you ride the more you realize the scope of data we humans process without noticing. This Ioniq was identified only by its Korea-spec origins — dual charging ports for fast and regular recharge and no side marker lights — and Nevada's autonomous vehicle license plate. Tourists were completely unaware that it was driving itself. The autonomous Ioniq uses one 140-degree and two 110-degree Ibeo LiDAR units in the front fascia, plus a camera array inside the cabin at the top of the windshield. A single camera is used for traffic-light detection, with stereo units for the driving assistants. According to Hyundai, the autonomous gear detects objects knee-high but also will not drive into a low-hanging tree branch. We're also told the system works in rain and snow, citing the all-conditions approval certificate from Nevada, though that center front sensor looks prime for snow packing in heavy stuff. Essentially, one processor collects all the input data and combines it to a singular view, and a second processor tells the car what to do about it. Hyundai notes that minimal system power consumption was a primary target. The cabin sports the prototype-standard large red kill switch, an extra display atop the center of the dash, and two real-time monitors hanging behind the rear seats. The dash display is there so human drivers know the car is aware of its surroundings — it shows traffic lights as red or green (yellow is not detected but it will not panic stop if it loses a green light), speed limit, vehicle speed, route, a steering wheel to denote autonomous operation, and pedestrians detected. One rear monitor shows what the traffic-light camera sees, the other what the LiDAR units are picking up, from road curbs to people, vehicles and buildings. The ride experience is drama-free if a bit on the cautious side. Braking is often moderate to heavy, more on/off than the modulation range of many human drivers, but we felt no panic braking or ABS intervention.

Hyundai Tucson Adventuremobile ready for camping at SEMA

A troop of customized 2016 Hyundai Tucsons will be making their way to the company's SEMA Show display in Las Vegas, NV, this year, and now there'll be one more in attendance, too. Joining hardcore offroad and high-horsepower takes on the crossover is the Adventuremobile from tuner John Pangilinan for those that love the outdoors but still need a vehicle to commute to work during the week. The Adventuremobile has everything for a camping excursion. There's no worry about where to rest in the wilderness thanks to a roof-mounted tent that sleeps two, and solar panels keep electronics topped up. An LED light bar should mean no problems finding the perfect spot, either. Even the cabin is a comfy place for a drive to the campsite with an upgraded stereo and Katzkin leather upholstery. The crossover looks rugged thanks to a coat of army green paint, but this tuned Tucson keeps the rest of the mods fairly realistic for the average adventurer. For a little added ability offroad, there's a 1.5-inch suspension lift and Toyo Open Country A/T II tires on some Rays wheels. The powertrain also gets some small tweaks with some new plumbing by AEM and a Magnaflow exhaust. The whole package seems like a great tool for spending a weekend in the woods. JOHN PANGILINAN CREATES TUCSON ADVENTUREMOBILE FOR SEMA FOUNTAIN VALLEY, Calif., Oct. 19, 2015 – John Pangilinan, the renowned Southern California tuner known for creating vehicles that blur the lines between lifestyle and automotive, has released details on his 2016 Tucson SEMA build. Dubbed the "Adventuremobile," the vehicle blends Hyundai's new crossover platform with a passion for the great outdoors, perfect for the weekend getaway. The car will be revealed at Hyundai's SEMA press conference on November 3 at 11:30 a.m. PT, in Las Vegas. The "Adventuremobile" is just as home on the daily commute as it is lugging gear up into the mountains for the weekend out of town. Most obvious is the addition of a Treeline Tamarack roof-top tent, with ample room to sleep two campers, and Goal Zero solar panels to power all of their accessories. The exterior has been beefed up with the addition of an Aries bull bar and side steps, Rigid Industries LED lights, and the vehicle has been finished in a BASF army green paint scheme by Strasse Sport. A custom 1.5-in.
