Maybach Pullman, S550 4Matic coming next

Mercedes-Benz officially revived the Maybach name as a sub-brand with the reveal of the luxed-up S600 at the LA Auto Show last week, but that's only the tip of the proverbial iceberg when it comes to the German automaker's new plans for its uber-prestige marque. Motor Trend reports that Mercedes is planning two additional Maybach variants to launch in the near future, both of them also based on the S-Class. First up, we're told to expect the even longer Pullman limousine to launch, complete with Maybach treatment, at the Geneva Motor Show next March – although this model won't necessarily be offered in America. Whether it will or not, the Mercedes-Maybach S600 Pullman will be even bigger, more luxurious and more expensive than the one just unveiled. What is being planned for US customers, however, is an Maybach S550 4Matic. Mating the 4.7-liter twin-turbo V8 to all-wheel drive would be a boon for wintery upscale markets, and is reportedly a more feasible option than trying to pair the V12 to the 4Matic system. As for other model lines, we've heard rumors of a Maybach GL-Class utility in the pipeline, but have yet to receive any such confirmation. Car confirms, however, that we shouldn't expect to see AMG versions of Maybach models. The two are being cultivated as separate pillars atop the Mercedes range – one focused on performance, the other on luxury – and never the twain shall meet. The previous model line did breed a sportier Maybach 57 S, however, and we wouldn't be surprised to see a similar treatment applied to one of the new models should Daimler find there's demand. In related news, MT also reports that a new S-Class Cabriolet is coming around the corner, and that the G550 is preparing to drop its aging 5.5-liter V8 in favor of the GL's 3.0-liter twin-turbo V6.

2014 Mercedes-Benz SLS AMG Black Series [w/video]

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.
Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.
The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

Mercedes-AMG to phase out 5.5-liter V8 after next year [UPDATE]

UPDATE: A previous version of this story indicated that AMG's 6.0-liter twin-turbo V12 was still mated to a five-speed automatic transmission, however the latest models (including the S65 AMG sedan and coupe, SL65 roadster and G65 sport-ute are equipped with the newer seven-speed unit. Mercedes also reached out to point out that the 5.5-liter engine will be phased out gradually, not overnight. There's a lot to love about AMG's 5.5-liter twin-turbo V8. It produces as much as 577 horsepower and 590 pound-feet of torque, and delivers blistering performance to even the heaviest of vehicles. But try not to get too attached, because like its 6.2-liter, naturally aspirated predecessor, it's not long for this world. The latest word comes from Autocar, which reports that Mercedes will release the last applications for the 5.5 biturbo within these next two calendar years in the new GLE63 AMG and upcoming S63 AMG convertible. After that, even though it was only introduced in 2011, it will be phased out. Fortunately Affalterbach has a worthwhile successor already in place in the 4.0-liter twin-turbo V8 from the Mercedes-AMG GT. The smaller powerplant, already in store for the new C63, is already producing 503 hp and 479 lb-ft in S spec. That's still shy of the larger unit's output, but where the 5.5 is nearing the end of its production cycle, the 4.0 is just starting out. Of course the 4.0-liter biturbo isn't the only engine AMG is making these days. Smaller models (based on the front-drive platform) employ the 45-designation, high-output 2.0-liter turbo four. Models at the very top of the lineup, however, use a 6.0-liter twin-turbo V12 that may be a dinosaur, but with 621 hp and 738 lb-ft of torque on tap, still can't be beat.
