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 Sportspace Concept is a big, red wagon that previews the future

The Kia Sportspace Concept might preview some design elements for the next-gen Optima, but for now the Korean brand is keeping the focus on this somewhat sporty looking wagon on display at the Geneva Motor Show. Its shape is designed specifically to appeal to European tastes, and the styling comes from the company's design studio Frankfurt, Germany. Despite the European design ethos, there's no mistaking the Sportspace as anything but a Kia. Up front, it features a sharper version of the brand's familiar tiger-nose grille that runs horizontally to link the LED headlights. However, the major visual focus for the concept is the long roof and angled rear hatch. The designers even pitch the D-pillar forward for a slightly more sporty style. The interior almost appears to come from a completely different model. The combination of black upholstery with carbon fiber trim and large pieces of anodized aluminum makes it look like a very dark place for a drive. Kia is apparently trying to appeal to the Sportspace's Swiss audience, though. The company touts that there's enough room to store a set of skis by fitting them between the rear seats. Power for the Sportspace comes from a 2.0-liter turbocharged four-cylinder with 247 horsepower that spins the front wheels, but the automaker doesn't specify anything about the transmission that it all routes through. Looking at the current Optima, it isn't hard to see the future design evolving this way. Get a preview from this big, red wagon on the show floor of the Geneva show in our gallery, above. DESIGN OVERVIEW: THE KIA SPORTSPACE CONCEPT The working week is over. The late afternoon sun is glinting on the ice crystals in the road-side snowbanks and turning the snow-capped peaks ahead pink. The road snakes ahead towards a weekend of fun and action. The journey demands a swift, efficient and refined machine to allow the maximum pleasure to be extracted from the time available. This is exactly the role for which the Kia SPORTSPACE was conceived. Its muscular proportions are ready to deliver a safe, secure but speedy passage to the slopes. Its cosseting and refined interior provides convivial yet individual space for its four passengers. Its sleek and elegant lines – both inside and out – are functional but stylish, allowing its travelling partners both comfort and convenience within a bodyshape that stands out from the crowd. This is a concept that has extracting the maximum from life at its heart.

2021 Kia Seltos SX Turbo Design Driveway Test

As we showed last week, the new 2021 Kia Seltos provides an impressive amount of cargo space for its size and price point. It also has useful storage for small items up front and plenty of comfortable passenger space throughout. When this functionality is considered along side its lengthy warranty and generous features for your money, you get a pretty sensible choice. However, sensible choices are usually drab: Old ladies shoes, a La-Z-boy recliner, Subaru. The Seltos goes far beyond simple sensibility, however, by providing equal parts function and fashion. It boasts eye-pleasing proportions, creative design details and fashionable color schemes. Now, is the exterior a tad evocative of a Volvo XC40? Sure, but since when is looking like a hot thing from Sweden so bad?  In the above video, I walk around the Seltos to provide a better look at these creative details along with the interior's 10.25-inch touchscreen interface and storage solutions.  Related Video:
