11 Hyundai Genesis deliver a message to space

Hyundai is channeling a little of the style from 2001: A Space Odyssey in a heartwarming video about a young girl named Stephanie trying to get a very big message to her dad. Since he is an astronaut who orbits Earth in the International Space Station, her father isn't exactly an easy guy to get a hold of. Hyundai came to her aid with a cadre of 11 Genesis sedans driving in precise formation across a dry lakebed. In the end, the stunt also netted the automaker a Guinness World Record for the largest tire track image. It covered about 2.15 square miles and was visible to Stephanie's dad in orbit. Check out the video to see Stephanie's message and watch some precision driving from a group of Hyundais set to some classical music. This content is hosted by a third party.

Hyundai refreshes the Sonata for South Korea, and later the US

Thanks to its debut in South Korea, we have an early look at the revised Hyundai Sonata that will eventually reach the US with minor adjustments. And that's not just speculation. We reached out to Jim Trainor at Hyundai, who told us, "Much of what you have seen from Korea will be seen here, but there will be differences both on the exterior and the interior along with some mechanical and option differences." That said, we don't expect major changes to this Korean model. So without further ado, let's take a look. Up front is a thoroughly revised fascia. The most noticeable change is the grille, which descends much lower in the front bumper, much like those on the Elantra sedan and Elantra GT hatchback. The top edge of the grille appears lower, and that brings the whole nose of the car lower. The hood also has a few more creases running longitudinally. The exterior varies a bit between models, with the standard model getting a grille with slats and the 2.0T getting a mesh grille. The 2.0T also gets black headlight bezels and dark chrome all around. Though Hyundai didn't provide photos of the interior, the company says it has been changed, and some of the buttons will have a more premium feel. The 2.0T also gets a few exclusive interior bits to complement its unique exterior. The seats have more bolstering, and the standard steering wheel is replaced with a flat-bottomed piece. There are some functional updates to the new Sonata as well. Most notable is the introduction of an 8-speed automatic on the 2.0-liter turbocharged four-cylinder model. In the US, the turbo Sonata is only available with a 6-speed automatic. Hyundai also touts the introduction of wireless phone charging and lane-keep assist. The big differences between this and the US version likely involve visual tweaks and the packaging of some options. There's also the question of whether the 8-speed automatic will be available, but it would be odd if it weren't offered. The Korean model goes on sale later this year, and Trainor told us the North American debut is coming soon. Related Video:

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.
