Kia teases sporty hatchback concept ahead of Detroit

The UK arm of Kia just released a teaser image (click to enlarge) for a new concept car that will be unveiled next month at the Detroit Auto Show. With little information to go on, the single overhead shot of the unnamed concept shows that it will be a two-door hatchback with a 2+2 seating configuration.
The brief press blast, which is posted below, promises that this is a new concept vehicle, so it's unlikely that it has anything to do with the similarly shaped Provo Concept that Kia showed off earlier this year at the Geneva Motor Show. Kia says that it will release more images of the concept soon, but it won't divulge the full details about the car until Detroit.

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.

U.S. appeals court preserves $210M Hyundai-Kia fuel economy class settlement

A U.S. appeals court restored a $210 million nationwide class-action settlement for hundreds of thousands of owners of Hyundai Motor Co and Kia Motors Corp vehicles whose fuel economy estimates were inflated. By an 8-3 vote on Thursday, in a case closely watched by class-action lawyers, the 9th U.S. Circuit Court of Appeals in Pasadena, California, said vehicle owners had enough in common to let them settle as a group. It also rejected arguments by owners opposed to the settlement that the claims process was too burdensome, and that lawyers for the class had colluded with the automakers to extract a "sweetheart deal" that undervalued their claims. The case began after the U.S. Environmental Protection Agency found flaws in Hyundai's and Kia's testing procedures, prompting the automakers to lower fuel efficiency estimates for about 900,000 vehicles from the 2011, 2012 and 2013 model years. Lawyers for objecting drivers had no immediate comment. Hyundai said it was grateful for the decision. Kia and its lawyers did not immediately respond to requests for comment. The decision by Circuit Judge Jacqueline Nguyen upheld a settlement approved in June 2015 by U.S. District Judge George Wu in Los Angeles. Wu "made careful findings, which the objectors here largely do not challenge, and which more than support the judgment," Nguyen wrote. The decision reversed a divided three-judge 9th Circuit panel's January 2018 rejection of the settlement and decertification of the class action. That panel said Wu failed to assess whether differences in state laws prevented certification of a nationwide class. It also said used car owners should have been excluded because it was unclear whether they had relied on the South Korean automakers' fuel economy claims. Lawyers had said it would become much harder to obtain nationwide settlements if the panel ruling stood. Nguyen had dissented from the panel ruling. Circuit Judge Sandra Ikuta, who wrote it, dissented on Thursday. Ikuta accused the majority of failing to determine what law should apply to the nationwide class or how the settlement, and thus attorneys' fees, should be valued. "The majority's failure to correct these errors may be beneficial for the class action bar, but it detracts from compliance with Supreme Court precedent," Ikuta wrote. The 9th Circuit covers nine western U.S. states, Guam and the Northern Mariana Islands.
