Kia blind spot monitoring and crash avoidance wins 2020 Autoblog Technology of the Year Award

The Autoblog 2020 Technology of the Year winner is Kia’s blind spot system. We judged the combination of blind spot monitoring and active blind spot crash avoidance on the 2020 Kia Telluride as the best in the industry. The Kia blind spot system won with 204 points, beating the Mercedes E-Active Body Control (189), Subaru DriverFocus (182) and Ram Multifunction Tailgate (139). AutoblogÂ’s editorial staff extensively tested the technologies last fall in Michigan. Three main questions were asked, and editors assigned point values out of 10 based on how well these technologies answered them. The questions were: What is its purpose? Does it work? Does it advance the industry? KiaÂ’s system starts with a traditional blind spot warning light in the side mirror. When equipped with the available head-up display, thereÂ’s a second warning light beamed onto the windshield in your line of sight adjacent to other information. This lets you know if thereÂ’s a car in your blind spot without even turning around to look. It isnÂ’t a feature exclusive to the Telluride (Mazda does something similar), but Kia takes it a step further. The next level of warning is slightly more intense. If you activate the turn signal while the car senses something is in your blind spot, the steering wheel begins to gently vibrate. ItÂ’s not a violent or distracting buzz, but itÂ’s enough to grab your attention. A warning chime is also activated at this time. 2020 Tech of the Year Winner.00_12_25_10.Still030 View 24 Photos The cherry on top is something Kia calls the “Blind Spot View Monitor.” It uses a system of cameras to display a live camera feed of either the left or right blind spot in the central digital portion of the gauge cluster when the turn signal is activated. Hyundai uses a similar system in the Palisade and new Sonata. The monitor in the cluster allows you to see your blind spot from the ground up in the gauge cluster without having to turn your head. The view is dependent upon road conditions, but itÂ’s a nicely integrated blind spot camera feed – the resolution is solid, and itÂ’s still useful to a degree at night. We find KiaÂ’s implementation to be superior to HyundaiÂ’s, where the camera feed takes over the digital speedometer or tachometer when you flip on the turn signal. Kia sets the camera feed in the center screen where the trip computer normally displays.

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.

Chevy Bolt wins 2017 Green Car of the Year

We knew that a plug-in vehicle was going to win the 2017 Green Car of the Year award this year, given that all five finalists have a way to charge up. And when Ron Cogan, the editor and publisher of Green Car Journal, announced the winner – the 2017 Chevy Bolt EV – he said that the car itself represents one of those times in the auto industry when everything is about to change. Similar to the invention of the starter motor, things are about to get different. For now, though, the fact that the Bolt EV won an award sounds like the same old thing all over again. Just this week, it was named Motor Trends Car of the Year and to the Car And Driver Top 10 list. The other four finalists for Green Car of the Year included the Toyota Prius Prime, the Chrysler Pacifica, the Kia Optima (including hybrid and plug-in hybrid models) and the BMW 330e iPerformance. Last year, the winner was the 2016 Chevy Volt. Did Green Car Journal make the right selection this year? See the award ceremony below.
