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.

Kia Niro Concept is the miniature Soul of the future

The Kia Niro Concept has officially made its Frankfurt Motor Show debut, and aside from the product specialist who would not get out of our photographer's way, this was our first in-person look at the Niro Concept, which first broke cover near the end of last month. The compact, rough-and-tumble crossover would slot in below the Soul were it to enter production, with Kia calling it a B-segment competitor.
The Niro sports neon accents, although both the trim and the actual color of the car itself are far lighter than they appeared in the original press photography. The cabin, meanwhile, looks like it was completely crafted from a single piece of rubber. We suppose that'd make it easy to clean out, sort of like a Jeep Wrangler.
Kia claims the Niro was designed "in Europe with European tastes" in mind, and that its production options will be based on the response of the general public. Take a look above for a full gallery of live photos, and then down below for the press release and images from Kia.

2024 New York International Auto Show Editors' Top 5 Picks

The New York Auto Show, like many other shows over the past few years, has shrunk. But it's still playing host to some interesting reveals, and we even got a few surprises this year. It was dominated by Nissan and Hyundai Motor Group products, but ones running the gamut from affordable cars to flagship SUVs. It was a strange situation of being both quite diverse in reveals, and not at all, depending on how you looked at it. Our favorites of the show are a clear representation of that. And another interesting observation, only one of the picks was significantly electrified. Scroll down to see the best reveals of the New York Auto Show,. 2025 Nissan Kicks View 10 Photos 5. Nissan Kicks "The Nissan Kicks has gone from a reasonably attractive and small crossover into something way more funky with cool textures, color combinations and some actual presence. Plus, it's more spacious, more powerful and has available all-wheel drive. If Nissan can keep the price nice and low to compete with similarly stylish and well-executed competition like the Chevy Trax, the company's got a real winner on its hands." – News Editor Joel Stocksdale InfinitiQX80-Z63-051 View 39 Photos 4. Infiniti QX80 "The QX80 wasn't technically shown at the New York Auto Show, but it was revealed just a week prior at Hudson Yards – accross the street, in other words. Frankly, I wasn't blown away by the initial photos, but I think it looks great in person. The attention to detail both outside and in seem appropriate for an SUV that Infiniti hopes to sell for six figures loaded up. I'm a believer." – Associate Editor Byron Hurd 2025 Kia K4 Live View 7 Photos 3. Kia K4 Sedan "The Kia K4 interior has way more style than anything in the compact car price range has any business having. Now, if we don't get the green interior option shown in the initial global reveal photos, I'm retracting several of my points here. Otherwise, wowza. I kept looking and looking at that K4 interior photo, and finding new, interesting details to admire. Oh, and the exterior is pretty cool, too, though I do prefer the hatchback in that regard." – Senior Editor, West Coast, James Riswick Genesis GV60 Magma Concept View 10 Photos 2. Genesis GV60 Magma "I am psyched to see Genesis show off a proper performance car. The “Sport” trims on its various models are sort of neat, but the Magma brand looks like the real deal.
