Major automakers urge Trump not to freeze fuel economy targets

WASHINGTON — Major automakers are telling the Trump administration they want to reach an agreement with California to avoid a legal battle over fuel efficiency standards, and they support continued increases in mileage standards through 2025. "We support standards that increase year over year that also are consistent with marketplace realities," Mitch Bainwol, chief executive of the Alliance of Automobile Manufacturers, a trade group representing major automakers, will tell a U.S. House of Representatives panel on Tuesday, according to written testimony released on Monday. The Trump administration is weighing how to revise fuel economy standards through at least the 2025 model year, and one option is to propose freezing the standards through 2026, effectively allowing automakers to delay investments in technology to cut greenhouse gas emissions from burning petroleum. The National Highway Traffic Safety Administration has not formally submitted its joint proposal with the Environmental Protection Agency to the White House Office of Management and Budget for review. Even so, last week, California and 16 other states sued to challenge the Trump administration's decision to revise U.S. vehicle rules. Auto industry executives have held meetings with the Trump administration for months and have urged the administration to try to reach a deal with California even as they support slowing the pace of reduction in carbon dioxide emissions that the Obama administration rules outlined. One automaker official said part of the message to President Donald Trump at a meeting on Friday will be to consider California like a foreign trade deal that needs to be renegotiated. Automakers want to urge him to get automakers a "better deal" — as opposed to potentially years of litigation between major states and federal regulators. On Friday, Trump is set to meet with the chief executives of General Motors, Ford, Fiat Chrysler and the top U.S. executives of at least five other major automakers, including Toyota, Volkswagen AG and Daimler AG, to talk about revisions to the vehicle rules. Senior EPA and Transportation Department officials will also attend. Environmental groups are eager to keep the rules in place, saying they will save consumers billions in fuel costs. A coalition of groups plans to stage a protest outside Ford's headquarters in Michigan.

2017 Mercedes GLS brings Benz's flagship SUV up to date

Mercedes-Benz is continuing the revision of its entire crossover lineup with the introduction of the new GLS. A facelifted version of the existing GL-Class, the new GLS aims to serve as the flagship of the German automaker's SUV lineup in the same way that the S-Class does for its sedans, coupes, and convertibles. As an update (rather than a completely new model), the new GLS is physically mostly the same as the GL it replaces, but packs a comprehensive series of revisions to bring it up to date. Those revisions can be seen on the outside, with revised styling front and rear. However the real changes have been made underneath the skin. The seven-passenger interior features a new three-spoke steering wheel, instrument panel with media display, center console with touchpad control, ambient lighting, and even an available air ionization system. The interior trim has been redone as well, with available Designo Exclusive and AMG Line packages to individualize it further. The new GLS will be offered Stateside in four engine specs. The base model is the GLS450, with a 3.0-liter twin-turbo V6 producing 362 horsepower and 369 pound-feet of torque. Step up to the GLS550 and you get 455 hp (20 more than before) and 516 lb-ft of torque. There's a six-cylinder diesel option in the GLS350d, good for 255 hp and 455 lb-ft. And the performance flagship, of course, is the new Mercedes-AMG GLS63, with 577 horsepower and 561 lb-ft of torque. The standard versions come with 4Matic all-wheel drive and a nine-speed automatic transmission with additional settings. The AMG version gets a rearward-biased traction system and a seven-speed dual-clutch gearbox instead. The standard models ride on an improved air suspension with enhanced damping, but the GLS63 adds a Sport+ instead of Off-Road setting on the Dynamic Select controller. There's a low-range gearbox and locking center diff available as well for those who plan to go off-road. Mercedes has fitted the GLS with all its latest electronic systems, including Collision Prevention Assist Plus, Crosswind Assist with Attention Assist, Brake Assist BAS, Pre-Safe braking, and more. The optional Driver Assistance package adds Distronic Plus with Steering Assist, pedestrian detection, cross-traffic assist, active blind-spot monitoring, lane-keeping assist, and more. There's an optional intelligent LED lighting system and heated adaptive windshield wipers as well.

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.
