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.

Sunday Drive: A new Rambo Lambo takes center stage

Surprise! Autoblog readers love fast cars. Doesn't matter what shape; doesn't matter what size. As long as it's got big power, wicked acceleration, and ludicrous speed, you're interested. Take, for instance, the brand-new Lamborghini Urus. It's got a 4.0-liter twin-turbocharged V8 sending 641 horsepower and 627 pound-feet of torque through an 8-speed automatic transmission to all four wheels. It hits 62 miles per hour in 3.6 seconds, and has a top speed of 189.5 mph. Ludicrous speed? Check. And although you'd be hard pressed to draw a line straight back from the upcoming Urus to the old, off-road-ready LM002, at least you can say that Lamborghini does have a history of producing overpowered SUVs. A 5.2-liter V12 engine producing 444 horsepower and borrowed from the Countach certainly qualifies as big power, especially considering this was in the 1980s and '90s. A prime example just sold for nearly half a million bucks. Moving along to more traditional sportscars, we got a sneak peek at the next Porsche 911's interior, thanks to some intrepid spy photographers. And we spy with our little eyes some major changes to the quintessential German sportscar. Finally, we round out this Sunday Drive with two First Drive reports. Both are German, but past that, they couldn't be more different. Either way, ludicrous speed is all but guaranteed by either one.

Mercedes-Benz C350 Plug-In Hybrid promises 20 miles EV range, 5.9 seconds to 60

Mercedes-Benz has introduced its first hybrid C-Class to the US market with the new C350 Plug-In Hybrid. Despite its fuel-saving purpose, though, this C is not short on firepower. MB paired a 208-horsepower, 258-pound-foot, turbocharged four-cylinder with a 80-hp, 251-lb-ft electric motor for a potent overall output of 275 hp and 443 lb-ft of torque. That translates a 0-60 time of just 5.9 seconds and a top speed of 130 miles per hour. For those that aren't interested in such frivolous numbers, though, the C-Class can still impress in more environmentally friendly ways. It can cover 20 miles to a charge and will hit speeds of up to 80 miles per hour (although not likely at the same time). Naturally, fuel economy figures aren't available at this early stage. Beyond those powertrain changes, the C350 Plug-In is still the same relaxed, luxurious baby S-Class, with a class-leading interior that should really benefit from the quiet ride provided by an electric powertrain. Take a look at our full gallery of live images of the new C-Class hybrid, straight from the Detroit's Cobo Hall.
