Senator calling for answers from Hyundai and Kia over MPG debacle

Hyundai and Kia have already gone public with plans to make good on the inflated fuel economy claims scandal that has rocked both companies in recent weeks. But one US senator, Jay Rockefeller (D-WV), is skeptical that the general public will see much good from the proposal, and he's looking for answers.
To recap: Hyundai/Kia have agreed to compensate owners of 900,000 affected vehicles for real versus previously claimed fuel mileage (as well as adding in a one- fifteen-percent premium), by way of pre-loaded debit cards. It has been speculated that this payout could crest $100 million by the time the Korean automakers are done writing checks.
Said Rockefeller to The Detroit News, "While I believe this is a positive step, I am concerned that many affected customers may not learn about the program or may find it burdensome to participate in the program." Rockefeller would reportedly like to see a monitoring system for the paybacks more clearly defined, with the goal being as many wronged car buyers as possible getting the recompense that they're due.

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 finally settles inflated fuel economy claims lawsuit for $41.2 million

Remember when Hyundai and Kia changed their claimed fuel economy numbers for a bunch of models? That happened back in 2012, and Hyundai has finally settled a lawsuit concerning the economy adjustment with a payment of $41.2 million. The lawsuit was filed by 33 state attorneys general, as well as one from Washington D.C. Each state will decide how to use its money from the settlement. According to Hyundai, this settlement was an "amicable agreement," and the company also denies any wrongdoing in changing claimed fuel economy numbers. Hyundai also reports that the agreement was reached, in part, due to the reimbursement program instituted after the economy adjustment. This program allows owners to be reimbursed the extra fuel cost, with payments determined by miles driven. The payments are sent after an owner has an affected car's odometer checked by a dealer. In addition, Hyundai also offered lump-sum payments as an option after the results of a class-action lawsuit. So far, the company reports about 75 percent of eligible owners have participated in the program. This isn't the only major payment Hyundai has made concerning the fuel economy issue. In 2014, Hyundai paid roughly $300 million in fines to the EPA. The company was also sued for inflated fuel economy claims in South Korea. In the US, models affected by the adjustment include the Hyundai Santa Fe, Accent, Veloster, Sonata Hybrid, Tucson, Genesis and Azera, along with the Kia Soul, Rio, Sorento, Sportage and Optima.
