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.
