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.

2020 Colorado Winter Driver's Notes | Behind the Wheel S02 // E12

2020 Mercedes-AMG GLC 63 I’ve had bad luck with SUVs this winter. Especially performance ones. First, I got a 2019 Range Rover Sport SVR delivered on summers right as two feet of snow fell, rendering it undriveable. Then, coronavirus cancelled Easter Jeep Safari as well as my trip out to Moab in the 2020 Jeep Wrangler Rubicon Diesel. Thankfully, when this 469 horsepower luxury mall crawler was dropped off, the sun shone down and the snow (mostly) held off.  The first thing that I noticed was there were a few blank buttons throughout the cabin, something that you may see in an entry model vehicle, but IÂ’m not accustomed to seeing in an AMG. Not a great look for a vehicle with an $80,000 price tag. Thankfully that was where the disappointment ended. As soon as you press the start button, the engine fires up and the exhaust note is incredible. Hopping on the highway ramp near my house, I floored it, and the biturbo V8 had me pressed back into the driver's seat, and this wasnÂ’t even the S version that our staff drove last year. Inside and out, the GLC 63 was everything youÂ’d expect from Mercedes. The interior was immaculate, and while the infotainment wheel and touch pad may take some getting used to for someone who isnÂ’t familiar, by now I have it down so that I can use it without looking. And while the V8 left me smiling ear to ear, I was most impressed by the amount of useable interior space there is. I happened to be moving at the time of this review and while all of my large furniture was shoved into the back of a moving van, I was able to fit almost everything else in the back of the GLC. 2019 and 2020 Fiat 500X Trekking ItÂ’s hard to say goodbye to an AMG and then turn around and be excited when a Fiat 500X pulls in your driveway (I know, I know, automotive journalist problems). That being said, when the red Fiat pulled up, I found myself admiring it. I am very familiar with the 500X. Back in 2016 Autoblog had one for a year as our long term test vehicle. I drove that car everywhere, multiple trips up north in Michigan, and even tracked it at Gingerman Raceway for a few laps before the brakes started smoking.  The 2019 model I had in my driveway and the 2020 model I drove in the snow up in the mountains feel very similar to that car. The interior is stylish and surprisingly roomy. The greenhouse is airy.

Next Mercedes S-Class stretching into this 600 Pullman limo

To the concern of nobody in particular, Mercedes-Benz will not be re-upping its Maybach line of ultra-luxury limousines. No, instead the German automaker will be stretching its already roomy S-Class, to make this upcoming 600 Pullman version of the decked-out beast.
The car in our new gallery of spy shots is sporting beefy B-pillars and a massive set of rear doors that should allow perfectly graceful ingress and egress from what is likely to be a palatial rear space. (In one photo we can even see a long-wheelbase S-Class in line with the new Pullman, handily exhibiting the size of the new variant.) The exterior modifications are otherwise obscured, though we can guess at revised front and rear fascia and lighting elements, based on both end being heavily taped for these test runs.
It's a good bet that the Pullman will make use of M-B's twin-turbocharged V12 engine, though sources indicate that a hybrid version might eventually be in the offing, as well.
