2014 Mercedes-Benz E63 AMG rumbles on stage 4Matic style

Bruce Hornsby and his soothing piano skills helped introduce us to the 2014 Mercedes-Benz E-Class, but the monstrous E63 AMG sedan needed no entrance music as it rumbled on stage. The 550-horsepower (and up) sedan sat proudly alongside the rest of the redesigned E-Class on stage at the Detroit Auto Show, but stood miles apart in intention and execution.
In addition to a choice of sedan and wagon body styles, the E63 AMG will also offer buyers the choice of the standard 550 hp or an upgraded 577-hp S-Model; regardless of output, all 2014 E63 AMG models will come standard with the 4Matic all-wheel-drive system.
We already saw the E63 AMG's aggressive styling last week, but now we have a full assortment of live images for you to enjoy as well as the Mercedes-Benz press release, which is also posted below.

Missouri Mercedes dealer offering free Smart with every SLS AMG purchase

The Mercedes-Benz SLS AMG GT is an exquisite sports car that probably needs no help flying off dealer lots, even with a starting price of almost $200,000, but Mercedes-Benz of Kansas City has come up with an interesting incentive to sweeten the deal. For buyers who purchase a new SLS AMG from dealer stock before the end of the year, the dealership is throwing in a new Smart Fortwo from its inventory at no charge... with a required coupon no less.
In addition to being a great tactic to get a little free press, the spare car also makes sense as an alternative to the SLS, which measures more than 15-feet long - almost twice the length of a Fortwo - and has a 563-horsepower engine that sucks down gas at the rate of 13 miles per gallon in city driving (and even that's provided you don't give in to the devil on your shoulder). Plus, at the end of the day, this really isn't that big of an incentive. Being given a slow-selling $12,490 car for the purchase of a model starting at $199,500 represents about a six percent incentive, which is along the lines of a $1,900 rebate for a $30,000 car.
To get the free Smart, just visit the Mercedes-Benz of Kansas City Facebook page, redeem the coupon and then go buy yourself a new SLS AMG. Congratulations!

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.
