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.

Hyundai-Kia names former Audi, Lamborghini, Bentley designer as design chief

Luc Donckerwolke, former designer for both Bentley, Audi and Lamborghini, is succeeding Peter Schreyer as the lead designer for both Hyundai and Kia. This follows a significant shuffle within the Korean automaker's upper management. Schreyer — himself a former Volkswagen Group designer — will head design management. Chung Eui-sun, the son of company chairman and CEO Chung Mong-koo, was promoted as executive vice chairman. The head of Hyundai Motor America, Kyung Soo-lee, is leaving his position after just more than a year on the job. That's a lot of moving pieces at the top of Korea's largest automaker. Donckerwolke has been with Hyundai-Kia since 2015 when he left the Volkswagen Group to take over Genesis design. Some of his most famous designs include the Lamborghini Murcielago, Lamborghini Gallardo, Bentley Flying Spur and Bentley EXP 10 Speed 6. Schreyer led the design of the original Audi TT and has helped push forward Hyundai and Kia. The pair's influence can be seen and felt throughout the company's lineup. According to Reuters, part of the shakeup within the leadership follows a company announcement that third-quarter profits have fallen, sending shares to their lowest level in nine years.

Kia Soul EV ad campaign charges up with sexified hamsters

It's official: Kia's adorable Soul-hawking Hamsters have crossed that line. It was one thing when they first hit the scene, and we got a small chuckle out of their trimmer looks for the refreshed, 2014 Soul. This, though, is too much.
This is Kia's latest commercial for the 2015 Soul EV, and it starts off typically enough. The hamsters seem to be tinkering in a laboratory attempting to modify a standard, gas-powered Kia. But then, some Weird Science-like trickery occurs and, well, the results are rather disturbing.
You'll need to watch yourself if you want to experience the horror. Take a look, and then head into Comments and let us know what you think.
