2014 Mercedes-Benz E63 AMG S 4Matic [w/video]

Maybe you saw our recent blog snippet on a bunch of US journos getting pulled over in the middle of nowhere in Catalunya, Spain for driving a bunch of new 2014 Mercedes-Benz E63 AMG models. By all accounts, they weren't speeding - which makes me softly guffaw. I was there in that group, yet I had taken the more direct route into the mountains from Barcelona so that I could... well, so that I could go faster. No one hassled me and I had the Autovia all to myself. And it was the goodniks - the team players - who got nabbed because Spain had decided to suddenly enforce the never enforced "must carry an international driver's license" clause of the highway code.
The departing E63 AMG with 518 horsepower and 516 pound-feet of torque from its M157 5.5-liter biturbo V8 hasn't exactly been poorly received. It isn't as crisp as, nor as pleasantly evil as its C63 AMG kid brother, but we generally accept that the heavier and larger car will always feel, well, heavier and larger.
As part of the 2014 E-Class mid-cycle redesign, Affalterbach decided to give its E63 AMG more power and torque for the occasion. The base car now gives off 550 hp and 531 lb-ft, while the hotter S version I tested (formerly the AMG Performance Pack) produces 577 hp and 590 lb-ft. The other big novelty is that E63 sedans will be available with both rear- and all-wheel drive, while all US-spec E63 wagons will be 4Matic equipped.

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.

Recharge Wrap-up: liquid-cooled Tesla Supercharger, Acenta+ Leaf

A new video offers a close look at Tesla's updated Supercharger. Recently, Elon Musk spoke about the new charging station with a thinner, suppler liquid-cooled cable that is not only easier to manage, but has the potential to handle larger loads and offer quicker recharging. The first examples have been installed in Mountain View, CA, which we can see in this video. Besides the new cable, the new Supercharger also features a solid "button" on the charging handle as well as vents around the bottom of the unit. The video even shows thermal imaging of the new Supercharger, which shows the cable to be cooler than the cameraman usually records. See for yourself in the video above, and read more at Treehugger. Nissan has added a new trim level to the Leaf in the UK. The Acenta+ slots above the Acenta and just below the range-topping Tekna. It comes standard with the 6.6-kW onboard charger and Mode-3 32-amp (EVSE) cable. Using a fast charger, the Acenta+ Leaf can charge to 100 percent in just four hours. "We're delighted to add a new member to the Leaf family in the UK," says Nissan Motor GB Managing Director James Wright. "More than 9,500 Leafs have already been sold here and Nissan is the undisputed leader in the EV market. This new model delivers exceptional value and showcases the Leaf's incredible technology and engineering." Read more at Next Green Car. Mercedes-Benz Malaysia says its vehicles are compatible with B10 biodiesel blend. Malaysia recently announced a mandate for diesel to be sold blended with 10 percent palm-oil based biodiesel, after which, carmakers like BMW and Mercedes-Benz came forward with concerns over compatibility with their vehicles. "We have evaluated carefully the influence of B10 Biodiesel blends on our current diesel vehicles for the Malaysian market and we are now able to confirm its compatibility," says Mercedes-Benz Malaysia President and CEO Roland Folger. "We have service intervals of 12,000 km to ensure that our customers are not affected by the diesel quality. Our diesel-powered vehicles currently sold in Malaysia were seen to have run both smoothly and safely with the use of the B10 biodiesel blend." Read more from Paul Tan's Automotive News.
