Mercedes-AMG promises something fast is coming

"Something fast is coming." That's all that Mercedes-AMG is saying to accompany this latest teaser video. Don't get us wrong: we don't doubt the power-hungry nuts from Affalterbach for one second. They've got a pretty good track record of delivering the performance goods, after all. We just don't know what it is that they're on about is all. Not that something like that would stop us from hazarding an educated guess, though. Crank up your speakers, play the 19-second video clip and you'll hear what sounds very much like a V8 winding up and down through its rev range. In fact it sounds a lot like the note coming out the back of the Mercedes-AMG GT, which emits a pretty raspy, burblesome noise despite the pair of turbochargers that would ordinarily muffle the song. Couple that noise with flat handling around what looks like Hockenheim and our best guess is that we'll soon be treated to a more hardcore version of the AMG GT – something to slot in between the road-going GT S and the race-spec GT3 (which, it's worth noting, carried over the atmospheric engine from the previous SLS). We spotted such a beast undergoing testing at the Nurburgring just a few months ago, and have been anticipating its arrival ever since. The resulting track toy may not be called the Black Series, but we bet it'll be plenty wicked all the same - whatever it's called.

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.

Here's today's round of auto plant closures in response to coronavirus

More automakers have shuttered factories, as businesses everywhere work to slow the spread of the Covid-19 coronavirus — and as the pandemic slows sales and disrupts parts supply chains. On Friday, the following closures were announced: • Volvo will close its factories in Sweden and the United States from March 26 to April 14. Volvo's U.S. facility, in Charleston, South Carolina, makes the S60 sedan. Its assembly plant in Torslanda, Sweden, turns out the XC90, SC60, and V90. Other Swedish facilities make engines and component parts. A Volvo factory in Ghent, Belgium, that builds the XC40 and V60 closed earlier this week and is expected to remain offline until April 6. Volvo's four factories in China have been reopened after a shutdown earlier this year. • Jaguar Land Rover announced that it will suspend production at its assembly plants in the UK over the coming week. The shutdown is expected to last until April 20. Elsewhere, production continues at the company's factories in India and Brazil, and JLR's joint-venture plant in China reopened at the end of February. • Bentley is closing its factory in Crewe, England, for four weeks, effective today. • Bugatti has put its atelier in Molsheim, France, on hiatus. No date was given for when assembly of its supercars might resume. • Mercedes-Benz on Monday will shut down its SUV factory in Alabama and its van assembly plant in South Carolina. Both will remain closed for a minimum of two weeks. Tesla yesterday revealed that it will suspend operations at its Fremont, California, vehicle assembly plant next week, on order from local officials there. Yesterday's factory closure announcements also included the U.S. assembly plants for Toyota (until April 6), Volkswagen (through March 29), Subaru (through March 29), and Hyundai (no time period specified). They join GM, Ford, Chrysler, Honda, Nissan, and Harley-Davidson, which earlier this week announced the suspension of production at their facilities.
