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.

2018 Hyundai Kona Ultimate 1.6T Review | The muscle has arrived

The 2018 Hyundai Kona sure is a breath of fresh air. To date, if you were looking for a subcompact or "B-segment" SUV, it was probably going to be a bit dreary to drive with a slow, undesirable powertrain. Mazda's CX-3 is an exception, but its tiny interior is even more Miata-inspired than its driving experience. Really, everything in the segment has at least one fundamental flaw that makes it tough to recommend, and although the new Kona certainly isn't flawless, it's the first member of the segment to provide abundant power, all-wheel drive and a transmission that isn't depressing. After driving a Kona 1.6T AWD for a week, I found it to be pleasantly well-rounded, surprisingly good to drive, and just as competitive as our on-paper comparison suggested it might be. First, though, the engine. The Kona's standard 147-horsepower naturally aspirated four-cylinder is perfectly competitive in terms of power, and isn't saddled with a CVT or the Jeep Renegade/Fiat 500X's nine-speed box of highly confused gears. That amounts to a win, but the engine to get is the 1.6-liter turbo-four good for 175 hp and 195 pound-feet of torque. That's more than a Volkswagen Golf, and although this Hyundai mill sounds too much like a growly sewing machine under light acceleration, it's an acceptable tradeoff for acceleration that blows the doors off everything in the segment except the 201-hp Kia Soul "!" trim (and that car is front-wheel drive only). Testing from various publications indicates 0-60-mph times in the mid-to-upper-6-seconds range, which would be about 3 seconds quicker than just about everything else in the segment. Some are even in the 10s. That vast difference is one you'll immediately notice on back-to-back test drives, and an advantage you'll be happy to have in the long run when you consider its estimated fuel economy of 27 mpg combined is equal to the 147-hp base engine – and better than most in the segment. It's paired to a seven-speed dual clutch automated manual that's been been smoothed over from earlier Hyundai/Kia applications, no longer herking and jerking at low speeds, and more responsive to throttle inputs. That's the case regardless of the selected driving mode. In past Hyundai/Kia efforts, Normal could be too lethargic, while Sport could feel over-caffeinated. Here, they're actually appropriate for the situations their names imply.

2015 Hyundai Genesis recalled to replace tires

The Basics: Hyundai is recalling 11,142 examples of the 2015 Genesis sedan with production dates between March 3, 2014, and February 9, 2015. The Problem: The models have Hankook Ventus S1 noble2 tires that can develop cracks in the sidewalls, which could cause them to rupture or leak air. Injuries/Deaths: None reported, Hyundai spokesperson Jim Trainor told Autoblog. The Fix: Dealers will replace the tires. If You Own One: Hyundai expects to begin the recall on February 19. RECALL Subject : Tires May Develop Cracks in Sidewall Report Receipt Date: DEC 22, 2015 NHTSA Campaign Number: 15V864000 Component(s): TIRES Potential Number of Units Affected: 11,142 All Products Associated with this Recall Vehicle Make Model Model Year(s) HYUNDAI GENESIS 2015 Details Manufacturer: Hyundai Motor America SUMMARY: Hyundai Motor America (Hyundai) is recalling certain model year 2015 Genesis vehicles manufactured March 3, 2014, to February 9, 2015, and equipped with Hankook Ventus S1 noble2 tires installed as original equipment. The affected tires may develop cracks in the tire sidewall, resulting in a loss of air. CONSEQUENCE: Tire sidewall cracks could cause a rupture during use, resulting in a rapid air loss and loss of vehicle control, increasing the risk of a crash. REMEDY: Hyundai will notify owners, and dealers will replace the factory tires with tires of another brand, free of charge. The recall is expected to begin on February 19, 2016. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 138. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. Related Video:
