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 K900 flagship to make advertising debut during Super Bowl

Kia is already solidifying its advertising plans for the 2014 Super Bowl, targeting a 30-second spot for its new, rear-drive K900 sedan during during the biggest football game of the year. The cost for this half-minute of air time? $4 million.
Of course, Kia is no stranger to advertising during the Super Bowl, with the Space Babies and Hot Bot ads of last year and the Mr. Sandman spot in 2012. But the stakes with the K900, which see the Korean brand attempting emulate its corporate cousin/bitter rival Hyundai, by moving into the rear-drive luxury space, are far, far greater. After all, Kia's previous Super Bowl ads were all for models in established segments - the K900 is an entering a realm the brand has never played in before.
The Super Bowl spot will be the first exposure to the K900 for many potential buyers, and considering that the South Korean brand is targeting conquest sales, according to the report from AdAge, it's important that it makes a good showing on such a large stage. As for the theme of the ad, there isn't much speculation from the execs this early in the game, according to AdAge. Looks like we'll be waiting until February to find out.

Kia K900 looks, sounds snarly with forced induction in SEMA preview

Kia is getting all set for this year's SEMA Show in Las Vegas, and among its vehicles is something that seems pretty mean.
The Korean company is keeping details quiet about what's under the hood of what it calls the High-Performance K900, but from listening to this video it certainly sounds fantastic with quite a meaty growl. There might be some form of forced induction going on, though we can't say for sure. Elsewhere on the car, Kia isn't being so tight-lipped. The High Performance wears a custom shade of gray paint with a one-off body kit, featuring carbon fiber inserts. It also sports 21-inch gloss black wheels and black chrome trim.
Honestly, we were left scratching our head a little when LeBron James signed on to be the "luxury brand ambassador" for the K900. However, if he were driving this around Cleveland, the endorsement might make a little more sense. Check out the video above to glimpse the concept for SEMA, and read the little that Kia is saying about it in the release below.
