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.

2015 Hyundai Sonata gets a shadowy preview

It's only been on the market since 2010, but such is the hectic pace of the family sedan world that the Hyundai Sonata finds itself as the elder statesmen of the midsize segment. The current, sixth-generation sedan put the Korean automaker in the hunt with its audacious Fluidic Sculpture styling and bold powertrain choices (it was the first to eschew a six-cylinder option), but time has brought with it tough new competitors from the likes of Ford, Honda, Mazda and others, so it's time for a new model.
Previewed here in this official teaser rendering is an all-new, seventh-generation model, and at first blush, it looks markedly more conservative and refined than its predecessor, with more restrained surfacing and a more traditional six-sided grille. Scheduled for a world premiere in Korea later this month, the Sonata is expected to make its first show circuit appearance at the New York Auto Show in April.
Built atop a platform with significantly more advanced high-strength steel (51 percent vs. 21 percent) and increased use of structural adhesives, the Sonata's bones promise to be both more rigid (by 40 percent) and lighter. Cloaked in Fluidic Sculpture 2.0 bodywork, so far Hyundai isn't saying much about powertrain updates, but it is trumpeting a redesigned interior with a new infotainment interface and redesigned seats.

Kia, Hyundai testing big crossovers, and one looks like the Telluride

Big things are coming from Hyundai and Kia in the near future, and we mean literally. One of our spy photographers caught the companies each testing full-size crossover SUVs out in the snow. The Kia caught our attention in particular, because it looks quite a bit like the Kia Telluride concept from 2016. At the front of the Kia, the entire fascia looks boxy with nary a curve in sight. It also has low-set, squared-off headlights at the far edges; both prominent features on the concept, too. That theme carries over to the back, where the metal portion of the hatch looks plain and flat and is almost perfectly vertical. The glass area leans forward a bit. The taillights also look like those on the concept, with thin vertical portions that make a 90-degree turn inward at the top. A neat design touch not found on the concept are the slight glass extensions into the roof on each side of the windshield. When the concept Telluride was revealed, it was based on the Sorento platform and had a combined 400 horsepower. This power came from a 270-horsepower V6 and a 130-horsepower electric motor, which Kia claimed would provide 30 mpg in all-wheel-drive form. We expect that the Telluride will mainly be offered in non-hybrid forms, and perhaps in diesel form, since this prototype was testing alongside a Volvo XC90 diesel. But we also wouldn't necessarily rule out a hybrid variant like the concept. Kia and Hyundai both are getting serious about hybrids and electrification, and if Kia is targeting something like the XC90, which itself offers a hybrid powertrain, it would make sense that Kia is planning to offer a competing product. A Kia executive said news about the production model is coming "soon," so we'll probably learn more about the production Telluride sometime this year, probably no earlier than the New York Auto Show.

We're not sure what it might be called, but the last time Hyundai had a crossover bigger than the Santa Fe, it was called the Veracruz, so the name could make a return. Styling-wise, the front of this full-size crossover is right in line with the rest of Hyundai's new-generation crossovers. It has the split headlight design that first showed up on the Kona, with the lower lamps providing primary illumination, and the thin, scowling upper lamps working mainly as daytime running lights.
