Remember the days when it used to take a manufacturer months, if not years to develop a high-performance variant of a model? Well, in anticipation of the 2012 Geneva Auto Show the new SL63 AMG has been unveiled just five weeks after the SL550 made its initial debut.

The new SL63 AMG is lighter, more powerful and is up to 30 percent more efficient than its predecessor. Much like the Porsche 911 (991), Mercedes’ most iconic drop-top has turned to an aluminum bodyshell, reducing overall weight by 275 pounds, counteracting the added technological and safety features that contribute to a greater load. Now, the SL63 AMG is not a light car by any means. With a curb weight of 4,059 pounds it weighs just 500 pounds less than a full-size Chevrolet Silverado 1500.

Less mass to accelerate is always a good thing when it comes to a vehicle’s performance, but its even better when less is combined with more, namely in the form of horsepower and torque. For the first time the SL63 AMG will be available with two different power outputs. A standard SL63 AMG comes equipped with the same 5.5-liter twin-turbocharged V8 found in the CLS63, E63 and CL63 AMGs. In its tamest form the hand-built, power plant cranks out 530 horsepower at 5,500 rpm, and 590 lb-ft of torque from 2000-4500 rpm.

For most, this would be more than enough. But if you want to experience the engine’s full potential you can opt for the optional AMG Performance Package. This boosts the output from 530 hp and 590 lb-ft to 557 hp and 664 lb-ft. The added horsepower and torque aids in 0-60 times too, allowing the SL63 AMG to accelerate to the mark in 4.1 seconds, one tenth quicker than without the package. Other changes include AMG performance steering wheel, limited slip differential and red-painted brake calipers.

Putting the power to the rear wheels is the familiar seven-speed AMG SPEEDSHIFT MCT sport transmission found in the majority of AMG models. The four driving modes; Controlled Efficiency (C), Sport (S) , Sport plus (S+) and Manual (M) work in conjunction with a revised and upgraded AMG sport suspension and a new electro-mechanical steering system. Additional options include a locking rear differential, AMG performance suspension and ceramic high performance compound brakes and an increased top speed from 155 to 186 mph.

Exterior design has maintained largely the same as the previous generation. The front has a lower and streamlined appearance. The grill is still emblazoned with the oversized three-point silver star, but fog lights integrated into the lower grill have been replaced with sleek LEDs below the headlights. The rear of the 2013 SL63 AMG has changed more than the front, with taillights that are almost entirely red in color. The rear diffuser has been significantly reduced in size, and the AMG sport exhaust tips have changed from round to a trapezoidal shape.

The SL63 AMG will go on sale later this year. If you’re looking for a premium luxury roadster with plenty of creature comforts, and performance that will keep pace with all but the fastest Porsches, this might be the vehicle for you. However, you better have deep pockets. Although no pricing has been announced you can expect a base MSRP in-excess on $140,000.

2013 Mercedes-Benz SL550 Revealed

Many vehicles throughout automotive history have used “sport” and “lightweight” in their names, and the Mercedes-Benz SL-Class is one of them. The first generation Mercedes-Benz SL rolled off the assembly lines in 1952 and has given birth to such icons as the 300SL Gullwing and Roadster. Now, six decades after the initial launch the sixth generation SL promises to return to its roots with a renewed attention to increased performance and reduced weight.

The new 2013 SL550 is the first production-based Mercedes to feature an all-aluminum body structure. Steel is only used in the A-pillar for added safety in the event of a crash. Besides the extensive use of lightweight aluminum, panels behind the roof and gas tank employ even lighter magnesium in their construction, helping to reduce the weight even further.

The result of all this is a body that weighs in at 242 pounds less than that of its predecessor, 275 pounds less as a whole. All of this has been done even though the 2013 SL550 is almost two inches longer and over two inches wider than the fifth generation. Dr. Thomas Rudlaff, who is responsible for the aluminum bodyshell said “The effect is as if a large passenger has stepped out of the car.”

Ok, that’s one half of the “SL” concept. But the “sport” dimension of the vehicle has been upgraded and improved too. The 2013 SL550 has received significant changes under the hood and throughout the vehicle’s suspension. A new 4.6-liter V8 has replaced the outgoing 5.4-liter unit. Despite decreasing the overall displacement by 0.8 liters, peak output has increased to 429 horsepower. The amount of torque produced has jumped dramatically, increasing 32 percent, from 391 lb-ft to 516 lb-ft, thanks in large part to the addition of twin turbochargers, allowing the engine to produce large amounts of torque at relatively low rpms. Mercedes claims the 2013 SL550 will sprint from 0-60 mph in just 4.5 seconds, 0.8 seconds less than the previous model. Although no official figures have been released fuel economy and overall efficiency has supposedly inccreased as well, with the help of a ECO stop/start function and an economically 7-Speed Driver-Adaptive automatic transmission.

On the interior passengers can expect to have increased room and maneuverability as a result of the exterior’s greater dimensions. The spacious and luxurious interior the 2013 SL550 also features a retractable hard top that can be opened or closed in less than 20 seconds. On top of the SL550’s already technologically-laden design are two all-new features, FrontBass and Magic Vision Control (MVC).

FrontBass takes advantage of the spaces in front of the footwell. This area is where the woofers amplify the bass sound from the speakers, thus making for a high quality audio experience even when the roof is down. The second feature, Magic Vision Control is essentially a high-tech windshield wiper system. MVC dispenses washing fiuld onto the windshield in both directions of travel, allowing for reduced splatter and risk of over spray when driving with the top down. The MVC system also heats the fluid and wiper blade itself, which should come in handy getting rid of snow and ice during winter months.

The 2013 SL550 will be available in U.S. showrooms beginning in the Spring. Along with the initial launch Mercedes will be offering a special “Edition 1” model. The “Edition 1” includes unique features such as AMG 19-inch alloy wheels, designo exclusive leather with contrasting topstitching, AIRSCARF and Harman/Kardon surround sound system.  The exterior is finished in special designo crystal silver magno paintwork and the interior upholstery is covered in designo classic red/black leather with designo black piano lacquer wood trim.
