Mercedes-Benz recently launched a dedicated website for the SL65 AMG Black Series, and it's loaded with goodies for anyone who can't get enough of the uber coupe. The site has detailed info on all of the Black Series' features, as well as some new studio photos that we haven't seen before. Best of all, they've provided six new desktop wallpapers available in normal, widescreen, and iPhone sizes. We've compiled these beautiful high-res photos in a gallery and included the original shots if that's not enough.

The online editors of Motor Trend have decided to spill the beans, which allows us to finally confirm the information circulating the interwebs regarding AMG's latest flagship supercar, the SL65 Black Series.

AMG has cranked an extra 66 hp out of the twin-turbo six-liter V12, now boosted up to 670 hp, while stump-pullin' grunt remains the same at 738 pound-feet. Unfortunately, all that torque still needs to be converted through a conventional five-speed automatic. The power boost, however, is only part of the equation that unburdens each horse of 1.6 lbs, now pulling just 6.1 lbs-per-hp instead of the "lesser" SL65 AMG's 7.7 lbs-per-hp. That reduction is thanks in no small part (but many small parts) to an ambitious weight reduction program that does away with the folding hard-top in favor of a fixed carbon-fiber roof, itself shaving 88 of the total 570 lbs cut off the curb weight. That figure is now down to a slightly more manageable 4,080 lbs, which is still in SUV territory for a two-seat sportscar. Carbon fiber is also features on the flared front fenders, hood, rear underbody diffuser and racing buckets. That reduced weight is sprung on fully adjustable coils with an electro-hydraulic Active Body Control suspension and one-piece forged alloys wearing Dunlop Maxx GT tires in 265/35ZR-19 dimensions up front and 325/30ZR-20 out back.

A deployable rear spoiler, flat-bottomed steering wheel and Alcantara-clad interior also factor into the package, which Mercedes says would be capable of hitting 220 mph if it didn't electronically limit it to 186 (300 km/h), but 60 will come in the three-second range. The extra kit is complimented by a lower hood line enabled by the Black's exemption from pedestrian safety regs due to its small production numbers: Only 350 examples will be made in either silver, white, black or red.

As expected, the advent of a new SL also brings with it the arrival of a new AMG variant. Gone is the supercharged, 510-horsepower SL55 AMG. In its place, we welcome the new SL63 AMG, which uses AMG's naturally-aspirated 6.2L V8 making 538 horsepower and 465 lb-ft of torque. Like its standard-grade siblings, the new AMG SL is restyled, featuring a new-look fascia, side gills and revised rump. AMG-specific elements like a unique hood, a full aero kit, wheels that look lifted from a Porsche 911 Turbo, and all the requisite badging are also included. Inside, leather and carbon fiber adorn the cockpit, which is also outfitted with the usual assortment of electro-gadgetry, including Bluetooth connectivity that'll work with any phone so enabled.

The big news with the new SL63 is the addition of Mercedes' seven-speed twin-clutch SpeedShift MCT (Multi-Clutch Transmission) with four drive modes. Shifts with the MCT are promised to be smoother, faster and more fun overall than before. Fun's good. An optional performance package adds party favors like ceramic front brake discs, an AMG-enhanced version of the Active Body Control system, unequal-width front and rear tires, a limited-slip rear differential, a flat-bottomed steering wheel with metal shift paddles, and the AIRSCARF neck warmer system.

If the 538 horses of the SL63 aren't enough, or if you're just hell-bent on winning the numerological pissing contest in your law firm's parking garage, Mercedes also brings back the SL65 AMG, whose turbocharged V12 cranks out 604 horsepower and a BRABUS-like 738 lb-ft of torque. Pricing hasn't been announced yet, but rest assured, it'll be up there.
