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.

Next Mercedes S-Class stretching into this 600 Pullman limo

To the concern of nobody in particular, Mercedes-Benz will not be re-upping its Maybach line of ultra-luxury limousines. No, instead the German automaker will be stretching its already roomy S-Class, to make this upcoming 600 Pullman version of the decked-out beast.
The car in our new gallery of spy shots is sporting beefy B-pillars and a massive set of rear doors that should allow perfectly graceful ingress and egress from what is likely to be a palatial rear space. (In one photo we can even see a long-wheelbase S-Class in line with the new Pullman, handily exhibiting the size of the new variant.) The exterior modifications are otherwise obscured, though we can guess at revised front and rear fascia and lighting elements, based on both end being heavily taped for these test runs.
It's a good bet that the Pullman will make use of M-B's twin-turbocharged V12 engine, though sources indicate that a hybrid version might eventually be in the offing, as well.

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.
