Hyundai and Kia to invest in self-driving startup Aurora

Hyundai Motor Co said on Thursday it would invest in self-driving car software startup Aurora along with Kia Motors Corp to speed up development of autonomous vehicle technologies. "With the new investment, the companies have agreed to expand research to a wide range of models and to build an optimal platform for Hyundai and Kia's autonomous vehicles," Hyundai said. Aurora said in a blog post that Hyundai and Kia's investment is part of a series B financing round, which has now raised more than $600 million. Aurora, which just announced a partnership with Fiat Chrysler Automobiles, competes with Alphabet's Waymo and General Motors' majority-owned Cruise, among others.

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 ix25 Concept foreshadows B-segment CUV

Hyundai introduced an all-new crossover concept to the crowds at the 2014 Beijing Motor Show, showing the ix25, a near-production concept that heralds the arrival of a new compact CUV for the People's Republic.
Boasting Hyundai's "Fluidic Sculpture 2.0," the ix25 is a handsome little soft-roader that we could see slotting in nicely below the vehicle we call Tucson (the rest of the globe knows it as the ix35), and would serve as the entry point for Hyundai's Chinese CUV range. Under hood sits a familiar 2.0-liter, "Nu" four-cylinder, which we've sampled in assorted Hyundais and Kias over the years.
At 168 inches long it's ten inches shorter than a Ford Escape and five inches longer than the Soul, from sister company Kia. Despite these differences, the ix25 Concept's wheelbase is less than an inch longer (eight-tenths to be exact) than the Soul's 101.2-inches. More notably, the ix25 is roughly the size of the new Chevrolet Trax.
