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.

2014 Mercedes B-Class ED battery much bigger than previously stated

There was something unexpected hiding in the new configurator for the 2014 Mercedes-Benz B-Class Electric Drive: a $600 "Temporary range extender." Since we've never heard of such a thing, we had to click through for more. The official explanation runs like this: A suite of options to further increase your driving range includes added insulation of the doors and roof for to increase climate-control efficiency, along with an electrically heated windshield and a range-extending charge function. By pressing a button on the console prior to charging, the maximum charge level for battery will increased for the next charge cycle. The higher-capacity charge can provide up to 17 additional miles of range. The passive features that increase range should be standard in all models, we think. But we were more curious about the battery charge situation. How do you increase a maximum? And is it a good idea to do so? The configurator includes this disclaimer, after all: Range extender should only be used on a limited basis, and could shorten battery life if used excessively. How much is excessive? We investigate below. The B-Class ED has, according to the specs, a 28-kWh battery. First, let's understand what this "temporary range extender" is all about. The B-Class ED has, according to the specs, a 28-kWh battery. But Terry Wei, from the Mercedes-Benz USA product and technology communications department, confirmed to AutoblogGreen that the B-Class ED is actually hiding a 36-kWh battery, but the automaker is calling it a 28-kWh battery because that's how much energy capacity is used in day-to-day use. Most automakers publicly claim the actual capacity and then admit they use a percentage of it. The Chevy Volt, for example, has a 16.5-kWh battery pack, but a "full charge" only fills up around 65 percent of that. In the B-Class ED, the 28 kWh of useable energy provides an EPA-certified 87 miles of range. But, since there are eight kWh of reserve, the temporary range extender (we think of it as a software update accessed by a button) can access some of that and offer the aforementioned 17 miles. Now that we know what we're dealing with, this reminds us of an evolved version of the "remote wireless charging" feature that was touted in the Reva EV. Wei said that the reason the feature is optional is because Mercedes doesn't think most people will need it. Eighty-seven miles is plenty for your average EV driver, but when you want to have 100+ in the tank, you can.

Mercedes previews new C63 DTM racer alongside Edition 1

The new C-Class Coupe will undoubtedly be one of the main points of focus at the Mercedes-Benz pavilion in Frankfurt this year. But the Silver Star automaker will have more than just the base version to showcase. There's be the new AMG C63, and now two additional versions. First up is the Edition 1, the designation Mercedes often applies (in some markets anyway) to launch versions of exciting new models. For the C63 Coupe, the Edition 1 features a raft of upgrades, available in either standard (476 horsepower) or S (510 hp) states of tune. It's done up in one of two exterior appearance packages, in matte gray with either yellow trim or black. The Edition 1 also wears special 19-inch wheels in the front and 20-inchers at the back, ceramic brakes, enhanced aerodynamics package, more chrome and gloss-black trim, and an optimized interior with racing buckets. Alongside the Edition 1, Mercedes will also reveal the new DTM racing model in Frankfurt. And following the teaser sketch released the other day, it's giving us our first proper look at the new touring car right here. The new C63 DTM will replace the existing C-Coupe DTM (as it has been formally styled) that has represented the automaker in its local tin-top racing series since 2012 – winning seven races over the past four seasons, but not a championship yet. If looks are anything to go by, the new racing coupe could be up to the task. Special Model to Market Launch: Mercedes-AMG C 63 Coupe Edition 1: Inspired by Motorsport Affalterbach. Mercedes-AMG is bringing the C 63 Coupe Edition 1 special model to the starting line. The exclusive colour combination in designo Magno Selenite Grey with yellow film coating and black wheels with yellow painted rim flanges reflects the graphic design of the Frankfurt International Motor Show launch version of the Mercedes-AMG C 63 DTM racing coupe which will be used in the DTM next year. The special model is equipped with Performance seats and an aerodynamics package, highlighting its proximity to motorsport. The new Mercedes-AMG C 63 Coupe and C 63 S Coupe are also available as "Edition 1" special models from market launch. The extraordinary combination of exclusive design and equipment characteristics is inspired by the optical appearance of future Mercedes-AMG racing coupes which will compete in the popular DTM series in 2016. Two exterior designs address different customer wishes.
