Driving the 2021 Chevy Tahoe and big news from Hyundai | Autoblog Podcast #640

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by News Editor Joel Stocksdale. They discuss some of the big trucks Joel drove: the 2021 Chevy Tahoe and a Mil-Spec-modified Ford F-150. After that is a look at the latest car news including Trofeo versions of Maserati's sedans, Hyundai's new electric brand called Ioniq, and the BMW M3 Touring station wagon and Hyundai Elantra N-Line. They wrap things up with some musings on anniversary of the 19th Amendment to the Constitution and how cars played a role in it.

Recharge Wrap-up: meet the '66 ZelectricBug, DOE announces home-scale H2 refueling competition

The US Department of Energy has launched the $1 million H2 Refuel H-Prize competition to create small- to medium-scale hydrogen refueling systems. The systems could be home-scale systems that produce hydrogen using utilities at home for refueling, or medium-scale systems to supply locations such as retail centers, apartment complexes or small fleets. The DOE sees hydrogen fueling infrastructure as the biggest obstacle to fuel-cell vehicle adoption and putting the production and refueling in the hands of the consumer could be a way around that obstacle. Read more at Energy.gov and at Green Car Congress. Hyundai has announced a new six-speed automatic transmission with integrated electric motor for new hybrid models. The new configuration puts most of the hybrid powertrain components within the transmission, and the torque converter has been eliminated. The new engine clutch reduces drag with fewer clutch discs, and the mechanical oil pump has been replaced with an electric one. The result is fewer energy losses, improved efficiency and greater mileage. Read more at Hybrid Cars in Reuters or in the press release from Hyundai below. Zelectric Motors has completed its electric 1966 Volkswagen Beetle rebuild, and has put it up for sale. The '66 ZelectricBug, as it's called, is powered by a 50-kW electric motor and 20-kWh battery pack, and offers 120 pound-feet of torque. It has a range of 80 miles, and is capable of at least 100 mph. The stock transmission has been rebuilt. It also has some new goodies like high-performance sway bars, custom shocks, and LED lighting. The '66 ZelectricBug is priced at $45,000. Check it out in the video below and read more at Hybrid Cars. A startup called Alevo says it will build a billion-dollar factory in North Carolina to make longer-lasting lithium iron phosphate batteries. Alevo has purchased an old cigarette factory in Concord for $68.5 million, but it's unclear whether or not the company has secured the $1 billion investment to begin producing batteries. The company plans to create 2,500 to 6,000 jobs and produce several gigawatts worth of batteries per year, which is a tall order for a relatively unknown company. Read more at Gigaom, or in Alevo's press release below. Tesla owners in Shanghai will be exempt from the city's $12,000 registration fee. About 400 people have already received the free license plates in Shanghai, where the government wants to encourage alternative fuel vehicles.

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.
