Hyundai And Kia To Pay US $100M For Overstating MPG

Korean automakers Hyundai and Kia will pay the U.S. government a $100 million penalty to end a two-year investigation into overstated gas mileage claims on about one-third of their models. The government says the civil penalty is the largest for a Clean Air Act violation in U.S. history. The discrepancy was discovered after the EPA got complaints about lower-than-advertised mileage on Hyundai's Elantra compact. Audits discovered overstated mileage on the Elantra and other models from 2011 into 2013. Hyundai says it made honest mistakes in interpreting complex EPA mileage test requirements. Neither company admitted liability and both maintain they complied with the law. Generally mileage was overstated by one or two miles per gallon on 13 vehicles. But one vehicle's highway mileage was 6 mpg higher than the EPA tested. Auto News Hyundai Kia mpg

Kia to green-light GT and Provo for production?

Kia is looking to inject a bit more performance life into its brand, and according to Auto Express, the company is looking at creating sporty models based on two of its recent concept cars, the GT four-door from the 2011 Frankfurt Motor Show (shown above) and the Provo hybrid hatchback that debuted in Geneva last week (inset, right).
"The GT is close to being approved and going into production, but, as with all our cars, they have to be developed on a sound financial footing," Benny Oeyen, Kia Europe's VP of marketing and product planning, told Auto Express. When it debuted, the GT four-door was powered by a turbocharged 3.3-liter V6, reportedly good for 389 horsepower and 394 pound-feet of torque, mated to an eight-speed automatic gearbox.
The Provo, on the other hand, could stand as a sort of halo car for the company's B-segment offerings. It would ride on the same front-wheel-drive platform as the Rio compact, though Kia says it's eager to keep the concept's gasoline-electric powertrain intact. "Our brand is currently rational, but there's space for a B-coupe," says Oeyen. Of course, the company would indeed have to look at different naming possibilities for its B-segment coupe, since the week-old Provo is already stirring up some controversy.

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.
