Honda, Hyundai and Kia get best word-of-mouth recommendations in US

Forget advertising, incentives and, yes, even our excellently crafted vehicle reviews, sometimes the best way for automakers to sell cars is still good ol' fashioned word of mouth. In an attempt to measure this "word of mouth" power, The Boston Consulting Group, a management consulting firm, has created a new study called the Brand Advocacy Index (BAI). The index takes a look at how various industries perform from person to person. Those industries include automotive, smartphones, grocery, mobile telecommunications and banking.
The study polled more than 32,000 individuals across Europe and in the US to come up with the top 55 brands in these various industries. On the automotive side of things, the top brands in the US were Honda, Hyundai and Kia, all tied at 63 percent. On a global scale, Volkswagen and Toyota scored the highest with a 65-percent BAI rating (both in France). The average BAI for auto industry players tallied 50 percent.
As for companies in other industries, Apple's iPhone was the index's top-rated smartphone, Trader Joe's was the highest recommended grocery store, Virgin was sat atop the mobile telecom industry and USAA was the top retail bank. Scroll down for the full press release on the new study.

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.

Kia showcasing Optima T-Hybrid concept in Paris [w/video]

At the Geneva Motor Show earlier this year, Kia showcased a new diesel hybrid powertrain. And at the rapidly approaching Paris Motor Show, it will present that new technology in the Optima sedan concept you see here.
Called the Kia Optima T-Hybrid, the concept mates a 1.7-liter diesel with both a turbocharger and electric supercharger to a small electric motor and a 48-volt lead-carbon battery. The mild hybrid setup allows it to travel in electric-only model at low speeds and at cruise, regenerating brake power to recharge the battery. Kia said it chose the lead-carbon battery pack over lithium-ion because it's easier to recycle and does not require active cooling.
Because the powertrain is still under development, Kia isn't saying what kind of fuel economy or emissions figures it gets in the Optima T-Hybrid concept, but it is targeting a "significant reduction" in emissions and fuel consumption, while delivering 15 to 20 percent more power. Check out the system in action in the video below.
