Mr. Millen goes to Washington

Ever driven around DC? We have. And let us tell you, people drive like jerks in the nation's capital. Mostly because they think they're more important than you, and they're probably right. But Rhys Millen is out to put them all to shame.
In this latest video, the guy who Red Bull refers to as a "precision driver" (and who the rest of us would call one of the best drifters ever to burn rubber) takes to the streets of the District in his Hyundai Veloster Turbo. There he does what he does best around sites like Capitol Hill, Thomas Circle and RFK Stadium - the one-time home of the Washington Redskins and Montreal Expos (pardon us, "Washington Nationals") - all with a police escort of black Tahoes and Harley outriders. Scope out the action in the video below.

At meeting with automakers, Trump launches new attack on NAFTA

WASHINGTON — Ten American and foreign automakers went to the White House on Friday to push for a weakening of U.S. fuel efficiency standards through 2025, while President Donald Trump used the occasion to launch a fresh attack on the North American Free Trade Agreement that has benefited the companies. A draft proposal circulated by the U.S. Transportation Department would freeze fuel efficiency requirements at 2020 levels through 2026, rather than allowing them to increase as previously planned. Trump's administration is expected to formally unveil the proposal later this month or in June. "We're working on CAFE standards, environmental controls," Trump told reporters at the top of the meeting, referring to the Corporate Average Fuel Economy standards for cars and light trucks in the United States. Trump said he wants automakers to build more vehicles in the United States and export more vehicles. But much of the hour-long meeting focused on NAFTA. Trump blasted the pact involving the United States, Canada and Mexico as "terrible" and noted that negotiations to make changes sought by his administration were ongoing. "NAFTA has been a horrible, horrible disaster for this country and we'll see if we can make it reasonable," Trump said. Automakers have called NAFTA a success, allowing them to integrate production throughout North America and make production competitive with Asia and Europe, and have noted the increase in auto production over the past two decades with the deal in place. They have warned that changing NAFTA too much could prompt some companies to move production out of the United States. The chief executives of General Motors Co, Ford Motor Co, Fiat Chrysler, along with senior U.S. executives from Toyota Motor Corp, Volkswagen AG, Hyundai Motor Co, Nissan Motor Co, Honda Motor Co , BMW AG and Daimler AG met with Trump, as did the chief executives of two auto trade groups. Major automakers reiterated this week they do not support freezing fuel efficiency requirements but said they want new flexibility and rule changes to address lower gasoline prices and the shift in U.S. consumer preferences to bigger, less fuel-efficient 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.
