2015 Kia Soul EV production model glimpsed before Chicago

A few days before its on-stage reveal at the Chicago Auto Show, the production version of the 2015 Kia Soul EV has been spotted, tagged and bagged in this series of spy shots. On the EV captured by our photographer's lens, we can see unusual baby blue accents on top, on the mirrors and up front, as well as a closed-off "Tiger Nose" that is both taller and larger than the grille on the standard Soul. The special "Eco Electric" badge on the sides is useful for identifying the car in the picture, but we can't imagine it'll make the transition to showroom floor (at least, we hope). The Soul EV's rear side is different, too, with the bottom lights moved lower and the design of the main taillights tweaked a bit (compare our spy shots gallery to the standard model here). The wheels get a fresh five-spoke design as well. What lies under the new exterior? Some things we already know. The Soul is supposed to have a "class-leading" range of over 120 miles on a charge thanks to a 27-kilowatt-hour lithium-ion polymer battery pack. The electric motor offers 109 horsepower and 210 pound-feet of torque to create a 0-62 mile per hour time of under 12 seconds and a top speed of around 90 mph. What we can't see in these shots is a window sticker, but from what we've heard before, the Soul EV, "won't be priced to stimulate demand." Early predictions put the price at $35,000-$40,000 US – before government incentives – when the car launches in the US in the second half of this year. The gas-powered Soul starts at $14,400. We should learn more in Chicago later this week.

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 and U of M studying 'highway hypnosis'

Next up on the hot-button list of things that can kill you behind the wheel: "highway hypnosis." That's the zombie-like, autopilot phase you get into on a long highway drive when there isn't much to distract you, like curves or traffic. Digging further into what it is and how to combat it, Hyundai-Kia engineers and the University of Michigan are commencing a study that will measure brainwave activity in order to track the body's slide into highway hypnosis.
We're not sure how much overlap this has with Mercedes-Benz's Attention Assist, which tracks more than 70 in-car parameters to determine when you're not focused on the road anymore. That system is billed as an alarm against fatigue, in our experience it does more than that - if you use your phone while driving, for instance, it will chirp.
They don't know what form a warning system will take yet, but Hyundai-Kia plans to develop a method for warning drivers when they being to zone out. According to the National Highway Traffic Safety Administration, there were more than three thousand deaths and nearly 400,000 injuries due to distracted driving in 2011.
