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.

Daimler wants to cut EV research spending as it preps EQ

Daimler AG is hoping that the legwork it's done preparing its EQ electric-vehicle sub-brand will allow it to slightly reduce annual spending on plug-in vehicle technology. The Mercedes-Benz parent is looking to cut electric-vehicle research-and-development spending to $13.2 billion in 2017 from about $15.4 billion this year, Bloomberg News says, citing comments Daimler CEO Dieter Zetsche made to journalists in Hamburg, Germany, this week. Daimler's annual R&D spending is up from about $11.5 billion in both 2013 and 2014. Like its competitors – for example Audi and BMW and its i sub-brand – Daimler is aiming to have as much as 25 percent of its annual vehicle sales be battery-electric within the next 10 years as part of an effort to meet stricter greenhouse-gas emissions mandates in both Europe and North America. In fact, Mercedes-Benz and Daimler's Smart division collectively have at least 10 electric-vehicle models on their slates during the next few years, though Zetsche said the German automaker will continue to find ways to make its gas- and diesel-powered vehicles more fuel-efficient as well. Daimler introduced a concept version of the Generation EQ electric SUV at the Paris Motor Show late last month. It comes powered by two electric motors and is made up of a combination of steel, aluminum, and carbon fiber, and boasts a 311-mile single-charge range (on the relatively lenient European testing standards). The SUV also has 402 horsepower, and the ability to go from 0 to 60 miles per hour in less than five seconds. Zetsche said at the time that Daimler was prepping powertrains and platforms for electric sedans, wagons, coupes, and roadsters, in addition to SUVs. Additionally, Daimler's Deutsche Accumotive unit is producing the lithium-ion battery packs for the EQs.

Mercedes-AMG GT S aggressively priced at $129,900*

Just a few days ago we brought you leaked information regarding pricing for Mercedes' new flagship supercar. Now the German automaker has confirmed that the new Mercedes-AMG GT S will indeed retail for $129,900 (*plus a $925 destination charge). That may seem like a big chunk of change, and by most standards it is. But it starts to fall into reasonable territory when you put it into context. For one thing, it's not the most expensive Mercedes – not by a long shot. The previous SLS AMG fetched around $200k, and most anything else at the top of the AMG range – like the S63, SL63, G63 or GL63 – will set you back more than the new GT S, and don't even get us started on anything with the V12 and the number 65. The new Maybach S600 will set you back nearly $190k, and that bonkers G63 6x6 goes for over half a million. As for its rivals, the pricing places the AMG GT S right on pace with the Porsche 911 GT3 (whose 475 horsepower the Benz neatly trumps with 503 hp) and a good $20k less than the more powerful 911 Turbo. It also comes closer to the $115,900 that Audi charges for an R8 with a V8 than the $153,900 it gets for the ten-cylinder version, although the Benz edges closer to the latter in terms of output. The pricing does make it a fair bit more expensive than even the top end of the Jaguar F-Type range, which (short of the Project 7 speedster) maxes out at under $100k for the R model. Contrary to its predecessor and the SLR that came before, however, Benz is wisely staying out of Ferrari/Lamborghini/McLaren territory this time around. In short, Mercedes has clearly weighed its pricing strategy carefully. But if $130k is still too rich for your blood, the less potent base Mercedes-AMG GT will follow in the spring of 2016 with less power (quoted at 456 hp) and with a list price that's yet to be announced but promises to be a fair bit lower. In the meantime, deliveries of the GT S are scheduled to commence in April of this year. MERCEDES-BENZ ANNOUNCES PRICING ON ALL-NEW MY2016 MERCEDES-AMG GT S New Sports Car to Start at $129,900* January 23, 2015 - MONTVALE, NJ With the new Mercedes-AMG GT model range, the Mercedes-AMG sports car brand is moving into a new segment. As the second sports car developed entirely in-house by Mercedes-AMG, the GT has everything you would expect from an authentic Mercedes-AMG, from the characteristic styling, thoroughbred motorsport technology to the optimum weight distribution.
