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.

2016 Mercedes-Benz GLE priced from $52,025

Mercedes-Benz released its full 2016 model year lineup and pricing details, and we've learned that the M-Class-replacing GLE will start at $52,025, including $925 for destination. The German automaker confirmed a few changes to the rest of its lineup, as well. For the GLE, that $52,025 price gets you the base GLE350. The GLE350 with 4Matic all-wheel drive starts at $54,525. The rest of the GLE range consists of the diesel-powered GLE300d 4Matic at $53,425, the GLE400 4Matic at $65,525, the GLE63 AMG at $100,875, and the range-topping GLE63 S AMG at $108,025. Mercedes will also offer the GLE500e 4Matic plug-in hybrid, but exact pricing for that model has not been released as of this writing. The GLE models start hitting dealers in August. Pricing for the BMW X6-fighting GLE Coupe – available in GLE450 and GLE63 forms – is also unknown. Elsewhere in the range, Mercedes-Benz will offer a new, diesel-powered C300d 4Matic, which goes on sale in February 2016. We already know the C-Class gets a new C350e plug-in hybrid model this year, which will arrive in September. Finally, the C400 has been killed, replaced by the C450 AMG Sport. Pricing for these new C-Class models has not been released. The small SLK roadster will receive a refresh soon, where it will be renamed SLC. In the meantime, the base SLK250 is now the SLK300, and comes with a nine-speed automatic transmission. Finally, Mercedes confirms the CLA will get a special "Edition: Orange" model, available on the CLA250 and CLA250 4Matic, limited to just 750 units nationwide. A host of other, smaller updates are available across Mercedes' model range. Read all about them in the very detailed press release, below.
