Mercedes to roll out C63 AMG late in 2014 with 4.0L V8

The new 2014 Mercedes-Benz C-Class is upon us, launching initially in North America with turbocharged four-cylinder C300 4Matic and six-cylinder C400 4Matic flavors. But that's only the tip of the proverbial iceberg when it comes to the vast array of powertrain configurations that will be offered in the new C-Class in markets around the world. Orders will soon be rolling in for gasoline, hybrid and diesel engines with four, six or eight cylinders, driving the rear wheels or all four, with the seven-speed automatic transmission soon to be replaced by a new nine-speed unit. But what enthusiasts are really looking forward to is the next C63 AMG.
As BMW has done with the M3 (and new M4), Mercedes has gradually ratcheted up the cylinder count in its AMG C-Class, graduating from the 3.6-liter V6 in the original C36 AMG to the 4.3-liter V8 in the C43 AMG, then the 5.5-liter V8 in the C55 AMG before going the distance with the sublime 6.2-liter V8 in the C63 AMG. Like its rivals, Mercedes is expected to use turbochargers as a replacement for displacement in the next model, but unlike its Bavarian rival, it won't be losing any cylinders in the process.
Skipping the 5.5-liter twin-turbo V8 that has gone on to power other AMG models, the next C63 AMG is still expected to introduce a new 4.0-liter twin-turbo V8 producing between 450 and 500 horsepower. It'll also reportedly keep the same seven-speed automatic transmission (instead of switching to the new nine-speed), but the jury's still out on whether it'll come with rear- or all-wheel drive (or offer buyers the choice). The downsized V8 - codenamed M177 - is then expected to find its way into other models, but the C-Class will be the first to get it when it arrives before the end of the new year ahead.

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 S-Class priced lower from $92,900*

The massively overhauled 2014 Mercedes-Benz S-Class will start at $92,900, not including a $925 destination fee, when it arrives at US dealers in October. That's a 2.8-percent drop over the 2013 S-Class, although Mercedes is fast to point out that a drop in price doesn't equate with a drop in equipment for the executive sedan.
Besides an extra 20 horsepower from the 4.6-liter, biturbocharged V8, the S550 sports a standard panoramic sunroof, keyless start, a rear-view camera and LED headlights, taillights and interior lights. Adding the German manufacturer's 4Matic all-wheel-drive system bumps the S550's price up to $95,900.
If the S550 doesn't quite cut the mustard, you can wait until November, at which point Mercedes will quite happily sell you the new S63 AMG 4Matic for $139,500. Power is also up on the S63, from a max of 563 ponies with an AMG Performance Package to 577 horsepower as standard on the 2014 model.
