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.

Time to catch up with Jay Leno's Garage, including his Lamborghini Espada restoration

If you're already jealous of the time, effort and money that Jay Leno can devote to his massive car collection, prepare to get a little greener with envy with this latest video from Jay Leno's Garage. Instead of the usual format of discussing a model for about ten minutes and then taking it out for a test drive, this week Leno gives viewers on a tour of over a dozen projects concurrently happening in his stable. The breadth of the vehicles shown and the things being done to them run the entire span of the automotive hobby. At the same time, Jay's shop is working on just a simple restoration of his 1969 Lamborghini Espada (pictured), and at the other side of the building, the team is rebuilding a wood-bodied 1914 Detroit Electric from scratch. He eventually plans to slot a more modern electric drivetrain into it. If bikes are more your interest, there's a freshly completed Brough Superior just waiting for a ride, and if American models are your thing, a Ford Bronco is getting a Coyote V8 installed into it. You have some very specific tastes if you can't watch this clip and start wishing at least one of these vehicles could be in your own garage. Other than the personal projects his mechanics are working on in the shop, Jay gets to have them all, plus plenty more.

2014 Mercedes-Benz S-Class interior caught in spy shots

With the redesigned 2014 Mercedes-Benz S-Class getting closer to production, the camera-wielding crew over at Autospies somehow managed to get inside of the car to snap some detailed spy shots. As the prototypes continue to shed camouflage, it would appear that Mercedes-Benz is getting closer to unveiling the car, and with the Geneva and New York auto shows coming up, it could be sooner rather than later.
From what we can see of this car's interior, the overall look of the S-Class' cabin isn't a ground-breaking departure from the current car, but it has been completely redesigned with more advanced technology. The styling is now even more upscale with larger swaths of wood, more shapely door panels (without the built-in armrest cubbies) and the concept-like two-spoke steering wheel. The highlight of this car though is probably the two massive digital screens with one being used for driver information and the other used for navigation, audio and infotainment systems. One other detail we noticed about this car is that it was equipped with the new 360-degree camera that debuted on the new GL-Class and will also be used on the 2014 E-Class. We also know that the next-gen S-Class will be getting the new cloud-based MBrace2 infotainment system.
As for the exterior design, it looks like the next S-Class will carry a similar profile as the current car, but we can see through the camouflage that the new styling will fit in better with current Mercedes-Benz products. Up front, the grille is much larger is flanked by aggressive LED-trimmed headlights, while the rear view of the car shows us the LED brake light now at the top of the rear window, a more pointed trunk opening and a more squared-off rear fascia with exhaust outlets pushed to the corners.
