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 and Kia set aside $412 million for false mileage claims

We still don't know how the whole fuel economy ratings debacle is going to play out for Hyundai and Kia, but both automakers are preparing to make good on their promises to reimburse vehicle owners for lower-than-promised mileage figures. According to Automotive News, Hyundai and Kia have set aside a combined total of $412 million ($225 million for Hyundai and $187 million for Kia) as compensation, which will be sent out on a case-by-case basis via debit cards depending on the vehicle and the mileage driven.
Announced back in November, the exaggerated miles per gallon claims affect around 900,000 Kia and Hyundai products produced for the 2011 through 2013 model years sold in the US and Canada. This whole deal has had plenty of action ranging from suspected whistleblowing from a rival US automaker and even insider trading, but it has probably been most frustrating for vehicle owners who, in most cases, saw their vehicles' city and highway ratings drop between one and three digits.

Kia EV9 wins 2024 World Car of the Year and World Electric Car at New York Auto Show

The Hyundai Group refuses to release its kung-fu grip on winning prestigious vehicle awards, especially those for electric vehicles. In 2020, Kia took the overall World Car of the Year (WCOTY) title with the Telluride, won World Performance Car with the EV6 GT, and won the World Urban Car category with the Kia Soul EV. In 2021, after the Hyundai Group walked away with nothing but a free lunch, the Hyundai Ioniq 5 won the 2022 World Car of the Year laurels, plus World Electric Vehicle and World Car Design of the Year, followed in 2023 by the Hyundai Ioniq 6 winning the same three awards. Kia returns to the top step today, the new EV9 announced at the New York Auto Show as the 2024 World Car of the Year and World Electric Vehicle. Because the South Koreans like to do this in threes, the Hyundai Ioniq 5 N won World Performance Car.  One hundred automotive scribes from 29 countries tested 38 vehicles for the main prize. The qualifications for entry are that a car must exceed 10,000 units in production annually, be on sale in at least two major global markets, and be priced below the luxury options in their respective regions. The EV9 beat the BYD Seal and the Volvo EX30 to the WCOTY title. Thirty-two cars vied for honors in the electric category, the EV9 outdoing the BMW i5 and the Volvo EX30. The German and the Swede aren't leaving New York with nothing, however, as the BMW 5 Series and i5 won the World Luxury Car title, and the EX30 won the World Urban Car trophy.  The Hyundai Ioniq 5 N outdid 16 other performance cars. We're sure there are engineers in Germany looking hard into their beer right now, the Ioniq 5 N pipping the M2 and XM to the victory circle.  The surprise of the bunch is the inclusion of the Toyota Prius, the global hybrid icon thrashing 70 other entries to win the 2024 World Car Design of the Year award. The other two finalists? The Ford Bronco and the Ferrari Purosangue. Ladies and gentlemen, give it up for the Prius.
