Kia Soul EV will plug into Sky DC fast chargers, EZ-Charge network

As Kia gets ready to introduce its first plug-in vehicle to the US market, the 2015 Soul EV, it is also prepping some infrastructure improvements. The company announced today that it is partnering with Greenlots and ABB on offering Greenlots' Sky Smart Charging DC fast chargers at some West Coast Kia dealerships. Greenlots president Brett Hauser told AutoblogGreen that the program will expand to the East Coast in the future. While we don't yet know all of the monetary details quite yet – Kia says that "pricing structures and incentives" for the new EV will be coming later this month – but it appears that Soul EV buyers will be able to access the EZ-Charge network and there will also be something called a Kia ChargeUp card available. The CHAdeMO-compatible Soul EV is due to arrive in the third quarter of 2014 and the Korean company has high hopes for the car in the US. Take a closer look at the car in this video and read the announcement below. Greenlots is a San Francisco-based company that is trying to make vehicle charging as easy and open as possible. Last year, it helped with the installation of 13 DC fast chargers in the greater Vancouver, BC area. Kia Motors America Selects Greenlots to Provide EV Charging Access and Networking for 2015 Soul EV Rollout Kia to rollout Greenlots' SKY Smart Charging™ platform for seamless charging experience. SAN FRANCISCO – September 2, 2014 – Greenlots, a global provider of open standards-based technology solutions for electric vehicle (EV) networks, is partnering with Kia Motors America (KMA) and ABB, a global leader in power and automation technologies, to offer DC fast-chargers (DCFCs) at select Kia dealerships on the West Coast for the soon-to-launch 2015 Kia Soul EV. The partnership illustrates the increasing role interoperability among EV charging technology networks plays in meeting pricing flexibility demands from automakers and providing a seamless experience for EV owners. Unveiled in February 2014 at the Chicago Auto Show and rolling out in the third quarter of 2014, the Kia Soul EV is the centerpiece of Kia's Clean Mobility program, and bolsters KMA's line of environmentally conscious vehicles offering drivers an alternative to gasoline-powered transportation. The 2015 Soul EV is Kia's first ever all-electric, zero-emissions car to be sold in the U.S. Beginning in the third quarter of 2014, Kia will roll out Greenlots' SKY Smart Charging™ platform to its dealerships in California.

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.

EPA says it will more closely monitor fuel economy claims from automakers

The unintended acceleration brouhaha at Toyota led to the National Highway Transportation Safety Administration tightening the vise on recall procedures. Likewise, the fuel economy kerfuffle that blew up with Hyundai and Kia's admission of overstated fuel mileage claims could lead to the Environmental Protection Agency policing automaker assertions by performing more audits.
At least, that's what a senior engineer with the government agency said while in Michigan giving a talk, according to a report in Automotive News. What that actually means, however, is still in question. Just ten to 15 percent of new vehicles - something like 150 to 200 cars per year - are rested by the EPA to verify automaker numbers. The EPA's own tests include a "fudge factor" to adjust lab mileage for real-world mileage, and the agency still relies on automakers to submit data for tests that it doesn't have the facilities to perform. How much more auditing can the EPA really expect to do, or perhaps a more relevant question would be how much more accurate could the EPA's audits become?
The price of gasoline, the psychological importance of 40 miles per gallon to a frugal car buyer, an automaker wanting to further justify the price premium of a hybrid, all of these things contribute to fuel economy numbers that insist on creeping upward. Perhaps the senior engineer encapsulated the whole situation best when he said, "Everybody wants a label that tells you exactly what you're going to get, but obviously that's not possible. A good general rule of thumb is that real-world fuel economy is about 20 percent lower than the lab numbers." If the lesson isn't exactly 'buyer beware,' it's at least 'buyer be wary.'
