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.

Mercedes ML63 AMG Returns With New Engine and 518 Horsepower

15 Nov

Fifteen years isn’t a long time in terms of human history, but in the automotive industry it’s a lifetime. In 1996 the four major luxury brands in Germany, Mercedes-Benz, BMW, Audi and Porsche all had yet to produce a luxury SUV. That all changed in 1997 with the introduction of the first generation ML class. The first high-performance model, the ML55 AMG, model followed for the 2000 model year. Now, over a decade after the initial release, the all-new AMG variant of the third generation ML has been unveiled.

The new ML63, although redesigned on the exterior for the 2012 model year, leaves the most major changes hidden under the hood. With a large number of manufacturers including BMW and Audi turning to forced injection turbocharging for their new generation of vehicles, its no wonder Mercedes stayed in lock-step with the competition. This grocery-getter has received more horsepower and torque by replacing the outgoing 6.2-liter naturally aspirated V8 with the same 5.5-liter BiTurbo unit that has already made its way into other 2012 AMG models.

As if the 505 hp from the naturally aspirated unit wasn’t enough for driving the kids through the snow to their hockey practice, the new power plant produces 518 hp and 516 lb-ft of torque (550 hp and 560 lb-ft with the optional AMG Performance Package.) Peak torque is available from only 1,750 rpm, allowing the 2012 ML63 AMG to accelerate from 0-60 mph in just 4.7 seconds (4.6 with Performance Package) and reach an electronically limited top speed of 155 mph, or a raised limit of 174 mph.

All of this power and torque is transferred to the high gloss, titanium gray, 20 -inch, 5-spoke alloy wheels with 265/45 R 20 high-performance tires through the AMG SPEEDSHIFT PLUS 7-speed automatic transmission. Optional 295/35 R tires and 21-inch AMG alloy wheels are also available.

As with other current AMG models the ML63 AMG employs a “Controlled Efficiency” (C) mode if one so chooses. When engaged, the Eco-friendly transmission shuts down all unnecessary functions and turns off the engine while the vehicle is stationary. Mercedes must be aware most customers who purchase the new high-performance SUV do so without the regard of fuel economy or efficiency. Despite this, an Eco mode isn’t a bad thing. Especially considering the ML63’s fuel economy. According to Mercedes the new 5.5-liter engine has resulted in a 33 percent improvement over the 6.2-liter V8. The estimated combined economy is still marginal at 16 mpg, but that’s surely better than the second gen. average of 11 mpg. Especially when considering the vehicle’s weight and highly tuned engine.

On and off the road drivers will benefit from a reduction of 99 lbs from the previous generation. The ML63 will still feature a transfer case which delivers the 4-MATIC permanent all-wheel drive to the road surface. To make the ride quality even more refined the new ML63 will employ, for the first time, an ACTIVE CURVE SYSTEM for active roll stabilization. An AMG sports suspension with AIRMATIC Air Suspension is standard equipment, along with independent damper struts, automatic level control and an Adaptive Damping System (ADS).

In staying with the expectations of buyers the new ML63 AMG now features designo interior as standard equipment. The interior had been available, but only at significant additional cost. It is available in three different choices, designo auburn brown, porcelain or black. Other choices on the interior include a host of designo pieces, including black leather edging on the floor mats, trim in black piano lacquer and wood/leather steering wheel in black piano lacquer. Rounding out the options are AMG badges on the backrests of the front seats, outer rear seats and edges of the floor mats.

The ML63 AMG is certainly not something for everyone. Most people don’t need to have a high horsepower, gas hungry SUV with tons of luxury accompaniments. Despite this there are obviously enough people who are in the market for Mercedes’ top SUV; 13,000 of the second generation were sold over the 6-year production run and 24,000 have been sold in total.

If you are in the market for the 2012 ML63 AMG you’ll need to have deep pockets. No official prices have been released, but with the 2011 model having a base MSRP of $92,590 you can expect the new family hauler to fall somewhere in that ballpark.

Mercedes-Benz C63 AMG Coupe Black Series Unveiled

Just days after Mercedes AMG revealed their all-new powerful and fuel efficient, naturally aspirated V8 engine the M152, they have unveiled an all-new vehicle.

The 2012 C63 AMG coupe Black Series is the most powerful C-Class ever produced and has the performance to back up its aggressive styling and looks. As with the other three Black Series models that have been released since 2006, the 2012 C63 Black Series is a no-holds-barred version of AMG’s regular C63 coupe.

Unlike the fuel efficient 5.5-liter in the 2012 SLK55 the engine in the C63 Black Series is designed with one thing in mind, high performance. The 6.2-liter, naturally aspirated V8 cranks out a whopping 510 hp at 6,800 rpm and 457 lb-ft at 5,200 rpm, accelerating the two-door from 0-60 mph in just 4.2 seconds. This power and torque is handled by the AMG SPEEDSHIFT MCT 7-speed sports gearbox, with four driving modes including the fastest “Sport Plus” and “Manual” modes for lightning quick shifts.

Numerous styling and engineering cues were taking directly from the racetrack in an attempt to save weight and make the C63 AMG coupe Black Series as aerodynamic as possible.

The AMG Aerodynamics Package includes exterior winglets and a fixed spoiler at the rear. Both pieces are made from carbon-fiber and help to increase the downforce at the front and rear axle. Accompanying the weight-saving carbon-fiber elements are lightweight alloy wheels. The 19-inch titanium gray wheels use a special forging process that results in a weight reduction of 24.2 pounds when compared to conventional wheels. To make the special forged wheels perform to their maximum one might opt for the AMG Track Package. This package is made up of Dunlop sport tires measuring 255/35 R 19 in the front and 285/30 R 19 in the rear, and aid to increase the overall grip of the vehicle during spirited driving on road or at track days.

Despite not being easily visible, the undercarriage of the C63 AMG Black Series is just as focused as the exterior. This particular Black Series features a specially designed AMG sports coil-over suspension, along with a locking rear-axle differential as standard. The coil-over suspension allows the driver to choose a number of different settings and options to suit the individual’s specific needs and demands. The differential lock also enables the operator to choose from various setups depending on their driving conditions.

Finishing off the C63 AMG Black Series is the motorsport-inspired interior. The two front AMG sport seats keep the occupants secure and planted during even the most demanding driving conditions. Interior sections such as the red seat belts and dashboard finished in high-gloss black piano lacquer give sharp contrast to the steering wheel, seats, door trim, door armrests, center console and shift lever, all of which feature red stitching.

The 2012 C63 AMG coupe Black Series made its world premiere today at the famous Nurburgring and is scheduled to make its debut in the U.S. beginning in early 2012.

Pushing the boundaries of performance and fuel efficiency

1 Feb

By Matt McCarron

High performance and fuel efficiency are not something that tend to go hand in hand. However, German manufacturers, particularly Mercedes-Benz AMG and BMW Motorsport have embarked on a new quest. It’s no longer acceptable to have the car with the most horsepower and torque, or the one with the largest displacement engine. In today’s ever-evolving high-performance race to produced the world’s best super sedan, it’s much more important to leave the competition in the dust, and do it in a cleaner and more fuel-efficient manner.

There are three German manufacturers who produce a high-performance version of their standard family hauler. And although all three, Audi, Mercedes-Benz and BMW can claim to have the highest performing and cleanest burning engine, and subsequently the best vehicle, this comparison will only focus on two of the three. The major reason for this is because the Audi RS6 isn’t offered for the U.S. market. The Audi S6 is a very capable vehicle in its own right, but it really can’t compete with the likes of the CLS63 AMG and upcoming BMW F10 M5. For the record, the Audi RS6 officially gets a combined 17 mpg in Europe and is powered by a 5.0-liter twin-turbocharged V10, producing 580 hp at 6,250 rpm and 479 lb-ft of torque at 1,500 rpm.

Mercedes AMG seems to have fired the first shot in the latest super sedan war. In November 2010 Mercedes AMG revealed their all-new 5.5-liter twin-turbocharged V8 engine, replacing it’s predecessor, the 6.3-liter naturally aspirated V8. The 5.5-liter twin turbo offers a 33% increase in fuel efficiency over the 6.3 NA, resulting in an estimated 16 mpg city and 21 mpg highway. The 5.5-liter also produces more horsepower and torque, with 518 hp and 516 lb-ft respectively, 550 hp and 590 lb-ft with the optional AMG Performance Package, as opposed to the 507 hp and 465 lb-ft from the old power plant.

Although Mercedes AMG has been the first out of the gate in the sedan race for the U.S. market, their competition, namely BMW Motorsport have been busy in the secretive depths of Munich and Garching, preparing their answer to the 2012 CLS63 AMG, the all-new BMW F10 M5. Although details of the upcoming ‘bahn-burner have been numerous, few have been concrete. However there are certain things that seem to have been figured out. The F10 M5 will be powered a highly tuned version of the 4.4-liter twin-turbocharged V8 engine that currently powers the X5M and X6M. Horsepower estimates range from the upper 500’s to even 600 hp.

In a September 2010 interview with Kilometer Magazine, BMW Motorsport CEO Dr. Kay Segler said the F10 M5 will reduce CO2 emissions by 20-25 percent. “We had very clear targets, and we worked toward those targets. Twenty to twenty-five percent less CO2 output, day-to-day car and a pure sports car in one, and a beautiful design as well,” said Segler.

The location of the F10 M5 debut is still uncertain. However one thing is for certain, the fast-paced race to produce the greatest super sedan seems to be escalating, and is getting more intense with each passing day. Unfortunately, the verdict on the world’s best super sedan will have to wait for the foreseeable future, or at least until enough automotive journalists have had the chance to drive the F10 M5 to make an educated decision.
