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.

Man makes record-setting drive across the US in 28 hours, 50 minutes

Records, as the say, are made to be broken. Whether that's cramming the most hot dogs down your gullet, running a faster mile, or yes, driving across the United States, odds are that there's someone out there wants to eat more, run faster or drive harder. Speaking of that last example, the record for driving from a set location on the east coast, in particular the Red Ball Garage in Manhattan to the Portofino Hotel in Redondo Beach, CA, has been one that has fascinated gearheads since a guy named Cannonball Baker made the trek from New York to LA in 53 hours, 30 minutes, in 1933.
The competition saw its glory days when Car and Driver's Brock Yates came up with the Cannonball Baker Sea-To-Shining Sea Memorial Trophy Dash (more affectionately known as the Cannonball Run), although the record was most recently set by Alex Roy and his 32-hour, seven-minute trek behind the wheel of a BMW M5 in 2006. Now, there's a new champion, who made the trip from east to west in a scarcely imaginable 28 hours and 50 minutes, behind the wheel of a 2004 Mercedes-Benz CL55 AMG. That's works out to an average speed of 98 miles per hour over the course of 2,813.7 miles.
His name is Ed Bolian, and Jalopnik has a writeup of the epic voyage that details everything from the history of the Cannonball Run to Bolian's preparation and trouble finding co-drivers, to the trip itself. It is well worth a read.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.
