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.

After months of partially disguised “spy” photos and unofficial press photos, it’s finally here. Today Porsche officially released the first details and photos of the their most revered vehicle, the 911. After nearly five decades of production the rear-engined Porsche 911 has become one of the most iconic and recognizable automobiles in the world.

Despite having subtle changes over the years the tradition of the 911 has remained largely unchanged. The 2012 911, designated the 991 internally, has stayed true to those roots. Although Porsche says the vehicle is “all-new”, many non-enthusiasts might claim the 991 looks nearly identical to its predecessor the 997. However, a closer look at the new 911 reveals many changes.

The wheelbase has increased by 3.9 inches, along with a lower height giving the 2012 911 a more aggressive overall appearance. The weight of the body has decreased by roughly 100 pounds thanks to lightweight aluminum-steel composite materials. The new 911 also has a wider front track, new rear axle and electro-mechanical power steering, resulting in greater driving agility, response and dynamics. On top of these features, the new Carrera S also offers Dynamic Chassis Control (PDCC).

Another hallmark of the Porsche 911 is the high level of technology incorporated into each generation of the vehicle. The seventh generation is no different. According to Porsche the 991’s fuel consumption is up to 16 percent less than that of the 997. This improvement is made possible via a host of engine management systems, such as a start/stop function and electrical system recuperation. The seven-speed Porsche double-clutch (PDK) transmission also aids in the increased economy by letting the 911 “coast”. In addition to the PDK the 2012 911 will feature the worlds first seven-speed manual transmission.

In terms of performance the new 911 offers more horsepower from a smaller displacement engine. The 2012 911 Carrera is powered by a 3.4-liter flat-six engine, compared with the 3.6-liter in the outgoing model. Regardless of this reduction the horsepower remains unaffected. The Carrera S model still has a 3.8-liter with 15 more horsepower, boosting peak output figures from 385 to 400 hp. These changes enable the 911 Carrera to accelerate from 0-60 mph in just 4.4 seconds (with PDK transmission). Meanwhile the Carrera S does the same sprint with the PDK in 4.1 seconds.

The 2012 Porsche 911 will make its world premiere at the 2011 Frankfurt Motor Show in September, and is scheduled to arrive in the U.S. beginning in February 2012.
