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.

Keep it simple, stupid | 2017 Hyundai Ioniq Hybrid and Plug-In First Drive

The Ioniq is Hyundai's "golden medal project," conceived from the outset as a car to beat the Toyota Prius and be the most efficient on the market. Ki-Sang Lee, Hyundai's senior vice president in charge of eco R&D, promised that if they could accomplish that feat, he'd give every single engineer on the project a gold medal. The result of their work is an attractive trio – hybrid, plug-in hybrid, and electric – built on the company's first dedicated green vehicle platform. And Lee gave out more than 500 gold medals to his engineers. With a growing number of drivers – bolstered by Millenials replacing the buying power of baby boomers – who value efficiency and consider the environmental impact of their purchases, hybrids and electric cars should be a popular choice, right? While cheap gas has not helped to encourage people to make the switch to greener vehicles in the last couple years, the added cost and complexity of electrified cars have also been barriers to wider adoption. Hyundai's approach appears solid. The Ioniq hybrids are straightforward, affordable, and something drivers would be proud to own without appearing smug. So Hyundai has built the car people claim to want, but will the drivers show up at dealerships? The Ioniq is attractive for a number of reasons, not the least of which is pricing. The Ioniq Hybrid starts at $23,035, undercutting the Toyota Prius by $2,535 (with its base MSRP of $25,570). It's also more efficient, with EPA mpg figures of 57 city/59 highway/58 combined. The most efficient Prius (the Two Eco trim level) falls slightly short at 58 city/53 highway/56 combined. While the Ioniq Plug-In Hybrid doesn't have price or fuel economy figures yet – it doesn't go on sale until the fourth quarter of 2017 – we do know its 8.9-kW battery pack offers over 27 miles of all-electric range and can be topped off in 2.5 hours on a Level 2 charger. The Ioniq's green cred doesn't stop at its efficient powertrain. Sitting inside the cabin, you wouldn't realize that the soft plastics contain 25 percent sugar cane, or that the headliner and carpet contain about 20 percent of the same renewable plant material. There's no way to tell by look or feel that door trim uses recycled plastics mixed with wood powder and volcanic stone, making it 20 percent lighter. Interior metallic paints use soybean oil to lessen their environmental impact. Even better, it all agrees with the senses.

Hyundai and Kia adding Google Maps API to nav systems

Hyundai's Blue Link and Kia's UVO infotainment systems will be adding three Google features: Send2Car, Point of Interest Search and Local Search by Voice. Send2Car lets travelers send destinations to their vehicle's navigation system from a computer or via a mobile phone app, and the POI and local searches are continuously updated in Google Places' database. The new data service integrations mean that drivers will have more access to more destinations and be able to find them more quickly.
Hyundai hasn't said when the new features will debut nor on what model. Kia buyers will find them introduced on the 2014 Kia Sorento expected to roll into dealerships shortly, with the Forte sedan following. You'll find a press release on the updates below.
