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.

2016 Hyundai Sonata Hybrid starts at $26,825

The pieces are coming together for exactly what's on offer in the 2016 Hyundai Sonata Hybrids. We were able to drive the regular gas-electric and plug-in hybrid versions and were impressed with the feel behind the wheel, but before you know the price, it's tough to tell if the car makes any real sense. While the price for the PHEV is still shrouded in mystery, we at least now know how much it'll cost for the non-plug Sonata hybrid: $26,825, including $825 for destination. That's the same as the 2015 hybrid model. For comparison, the 2016 Ford Fusion Hybrid starts at $25,675 and the 2015 Honda Accord Hybrid comes in at $30,125. That's the base cost, which gets you the cloth interior and projector headlights. The 2016 Sonata Hybrid Limited starts at $30,100 ($900 more than before), which ups the 16-inch alloy wheels to 17-inch alloys and magically turns the interior to leather and the headlights to HID Xenon. If you want 60/40 split-folding rear seats, you'll need to opt for the Limited version. You can also tack on the Limited Ultimate Package for $4,500. The Limited Ultimate Package further improves the car's safety (with lane departure warning and forward collision warning) and sound (with the Infinity premium audio system). The LUP also adds a panoramic sunroof and an eight-inch nav system. Overall, there are seven exterior colors and five interior options. The PHEV price has not yet been announced, but whatever it is, Hyundai has said it expects the car to qualify for a $4,919 tax credit from the federal government.

Hyundai returns to flashier design with 2018 Sonata

Compared to the stylistic achievement of the 2009 Hyundai Sonata, many observers viewed the redesigned 2015 Sonata as a step backward. To right the ship, Hyundai tasked its North American Design Center with restoring some razzle-dazzle to the brand's midsize contender for 2018. The creative team made changes throughout, the biggest development being the "cascading grille" at the front, cribbed from the Elantra. The Sonata Sport 2.0T grille gets a silver mesh treatment and vertical LED DRLs tucked in the triangular bumper vents at the corners. The other models wear chrome bars inside the grille, with vertical and horizontal LED DRLs at the corners. Slimmer headlights stretch around the front edges, with the hood sporting deeper chiseled surfaces to emphasize the injection of style. In back, instead of the hint of a spoiler on the current sedan, the 2018 Sonata's deck lid ends in a pronounced flick above a sharp taper into the rear valance. The license-plate holder moves down to the reshaped bumper so that the larger, flatter trunk face can fit much larger badging. The trunk release button hides inside the Flying H emblem, and wedge-shaped taillights glow with the same alien-script pattern familiar from the Elantra. Down below, non-Sport models get a single, trapezoidal exhaust tip, but the Sport 2.0T gets two such exhaust tips, paired with new Michelin tires and a flat-bottomed steering wheel. Engines don't change, but buyers who choose the 2.0-liter four-cylinder get an eight-speed automatic transmission that adds a cog at the low end and another at the high end. The rest of the lineup sticks with the present six-speed auto. Handling upgrades include 12-percent thicker torsion bars in the steering system and new steering calibration for better on-center feel and responsiveness, plus 21-percent thicker trailing arms and new bushings in the suspension for faster response and more compliance. Inside, a reworked center console holds steady with a seven-inch touchscreen. Interior designers gave the new HVAC and audio controls a silkier finish and contrasting "piano key" buttons. A second-row USB port serves back-seaters, and the options list will include a Qi wireless charging pad for those in front. The 2018 Sonata introduces a navigation bird's-eye view, free traffic data, standard blind-spot detection and rear cross-traffic alert, and a new lane departure warning system as some of the convenience and safety highlights.
