The price increase takes into account that the 2013 car receives numerous upgrades, starting with an additional 20 horsepower (for a total of 583 hp) for the 6.2-liter V-8 engine. The seven-speed dual-clutch transmission has quicker shift times and the suspension is stiffer, and there are various aesthetic tweaks like tinted headlights, red brake calipers, gloss-black mirrors, and new Alcantara interior trim. The 2013 Mercedes-Benz SLS AMG GT reaches dealerships by the end of this year. Customers looking for a somewhat more practical AMG car should pay attention to the price tag of the GL63 AMG. 87,805 GL550 4Matic.

DIGITAL EDITOR ANDREW STOY: The more time I spend with the GL-class Benz, the better it gets. Or get the 2013 Mercedes-Benz GL63 AMG and have yourself a grand ol' time. Yes, it's thirsty, ridiculously expensive and completely unnecessary, but I have a difficult time thinking of a better way to shuttle seven passengers this side of a private jet. It never ceases to amaze me how much of a transformation that AMG designation imparts upon the base Mercedes from which it springs. I find the GL550 vaguely pointless, for example -- it's got great numbers, but the driving experience doesn't justify the extraordinary price jump over lesser GL models. Not so with the GL63, which snaps to attention with a stab of the throttle like a truck half its size. ROAD TEST EDITOR JONATHAN WONG: OK, so the 2013 Mercedes-Benz GL63 AMG tips the scales at over 5,800-pounds and Benz estimates that it's capable of going from 0-60 mph in 4.8 seconds and has a top speed of 174 mph. It all begins with hand-built 5.5-liter twin-turbocharged V8 giving us 550-hp and 560 lb-ft of torque between 2,000 and 5,000 rpm for a wide powerband.

To help it sound the part, there's a dual AMG sport exhaust system fitted that sounds absolutely mad when you stomp the right pedal, but remains quiet when just idling around normally. The seven-speed automatic gearbox does an admirable job with quick and smooth shifts. There is a manual mode and some slick aluminum steering wheel mounted shift paddles, but response is a little lazy. I preferred to just throw things in Sport mode and let the computer do all work. So does 60 mph in 4.8 seconds seem believable? It sure does. After the briefest delay in throttle response at tip-in, the engine shoots the GL forward alarmingly quick and power doesn't let up at any point as the needle on the tachometer sweeps towards redline. For a big SUV, I've always thought the regular GLs handled themselves well considering the weight and ride heights. In AMG trim, it's no different with the Airmatic suspension and adaptive damping system. Again, Sport mode makes the GL63 feel agile, all things considered. Steering response isn't bad with OK weight tuned in and the brakes with six-piston front calipers are real grabby.

If you need to get up to seven people someplace real quick, this is your vehicle. Under the hood of this high-performance SUV is a 5.5-liter twin-turbo V8 that churns out 550 horsepower and 560 lb.-ft. Mercedes claims lets it zip from 0-60 mph in under five seconds and reach a top speed of 174 mph. This potent powerplant is mated to an AMG seven-speed automatic transmission and uses an engine start/stop system to help optimize fuel economy. Complementing the potent drivetrain is AMG鈥檚 Ride Control sport suspension with automatic level control. This uses special struts with adaptive damping and active front and rear stabilizer bars to help control body lean during cornering. What鈥檚 new & notable? A special transfer case for the GL63鈥檚 four-wheel-drive system distributes more power to the rear wheels, in a 40:60 ratio, which Mercedes says helps give this large SUV 鈥渟ports car handling.鈥?Or at least, sports car inspired handling. When will it be available?
