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.

Win a car while supporting a charity this holiday season

Autoblog may receive a share from purchases made via links on this page. Pricing and availability are subject to change. No donation or payment necessary to enter or win this sweepstakes. See official rules on Omaze.  The leaves have fallen, there is a crispness to the air and there have already been multiple forecasts of snow, which can only mean one thing: We're coming up on Christmas. While you've been busy thinking about what kind of gifts you're going to give your loved ones, we here at Autoblog have been deciding which dream car we'd like to see in our driveway on Christmas morning. A car for Christmas does seem a bit extreme and expensive, but thanks to these Omaze sweepstakes, it doesn't have to break the bank. Here are the current sweepstakes we'd like to win this holiday season. Win a DeLorean DMC-12 - Enter at Omaze James Riswick, West Coast Editor: Let me be clear, the DeLorean is a pretty terrible car. Its speedometer doesn't even go up to the fabled 88 mph. Seriously, look at the pictures: tops out at 85. Also, who services a DeLorean? And how much would it cost to maintain one? $AlloftheMoney or just $MostoftheMoney? So owning it could be a total headache, but at least by winning one through Omaze, you'd be relieved of the financial burden of buying one in the first place. You'd also get the chance to own one of the most iconic cars of all time, one that transcends car enthusiasm and is instantly recognizable by everyone as the "Back to the Future" car. Plus, "everyone" doesn't know that the DeLorean was actually a pretty terrible car. So, I already own James Bond's car from 1995, why not Doc Brown's from 1985? Win a 2021 Bentley Bentayga V8 - Enter at Omaze Eddie Sabatini, Production Manager: Why am I choosing a +$200K Bentley SUV? Because even if I could afford one I'd never be able to wrap my head around spending money on one. So why not try to win one by donating what I can afford to a good cause? I first saw the Bentley Bentayga up close and personal at the Frankfurt Motor Show (I forget which year but I'll never forget this SUV). And although it looks like the Bentayga Omaze is offering up doesn't have the opulent tailgate setup I fell in love with when I saw it in Frankfurt, I'd still enter to win. Win a 1968 Mercedes-Benz 280SL Pagoda - Enter at Omaze Byron Hurd, Editor: Few automotive marketing efforts stick out in my head more than the Mercedes-Benz holiday spots and magazine placements.

2015 Mercedes-Benz GLA priced from $31,300*

Mercedes-Benz has kindly let loose the price of the 2015 GLA-Class, telling Autoblog.com that the base 208-horsepower GLA250 in two-wheel drive will go for $31,300 *not including a destination charge of $925. That makes for $32,225 in total to get one off the lot, a price predicted as early as last year and in our recent First Drive. The other two available models can push power to all four wheels, and after the destination fee is applied the GLA240 4Matic (pictured) will be $34,225 while the 355-horsepower GLA45 AMG will change lives and wallets to the tune of $49,225.
On the base scale, that puts the GLA250 just a few hundred dollar bills above the more powerful, rear-wheel drive BMW X1 and a stack of hundreds below the less powerful, front-wheel drive Audi Q3. If you're keeping in-house score, the GLA250 comes in at $1,400 above its sedan platform-mate with the same engine, the CLA250. At the high end, however, the competition doesn't have anything that can touch the AMG trim. Not that it should matter all that much - Mercedes needed something to keep these buyers in the family, and now they have it. If any of them should need even more power and more money spent, then there's always that 394-hp Brabus flavor. We'll have more info and details on each trim when Mercedes unleashes the shebang in the not-too-distant future.
