TORONTO, ON –The 2008 Mercedes-Benz S-Class line-up includes the S450 4MATIC, S550 4MATIC, and three limited-production models – the V12 S600 and S65 AMG as well as the V8-powered S63 AMG.
The successor to a long line of premium luxury vehicles, the new S-Class sedan was launched in early 2006 with the S550 model, powered by an all-new 5.5-litre V8 engine delivering 382 horsepower and 391 lb.-ft. of torque, also the first of a new V8 engine family featuring four-valve-per-cylinder technology and variable valve timing. The new S450 4AMTIC and the S550 4MATIC feature a totally redesigned all-wheel-drive system that’s integrated into the seven-speed automatic transmission.
The new S450 4MATIC is powered by a 4.6 litre V8 engine delivering 335 hp and 339 lb.-ft. of torque, featuring four-valve-per-cylinder technology and variable valve timing. The S450 4MATIC is paired with the 7G-TRONIC seven-speed automatic, a smooth-shifting driver-adaptive transmission that maximizes both performance and fuel economy.
AMG Racing Success Spawns High-Power Production Engine
One of the most powerful naturally aspirated production V8s ever, the new engine boasts a wealth of exciting features derived from AMG’s highly successful racing efforts. The S63 AMG features a 6.2-litre normally aspirated V-8 engine that produces 518 horsepower and 465 lb.-ft. of torque. Built almost completely from a high-strength silicon-aluminium alloy, the high-rpm 6.2-litre features four valves per cylinder, variable valve timing, bucket-type cam followers (rather than rocker arms), and a variable intake manifold. Designed exclusively by AMG, the engine shares no parts with other Mercedes-Benz V8 engines.
A first for a production engine, the cylinder bores feature a twin-wire-arc-sprayed (TWAS) coating, a new process that results in impressively low friction and running surfaces that are twice as hard as conventional cast-iron cylinders.
Exclusive AMG Styling, Inside and Out
The S63 AMG comes with special body styling, alloy wheels, sports suspension and high-performance brake system – all designed by AMG specifically for this new model. A muscular front bumper with large air intakes houses round fog lights ringed in chrome, and a “6.3 AMG” badge marks each front fender.
Contoured side skirts carry the aggressive lines of the front bumper to the rear, where an AMG rear apron emphasizes the width of the vehicle. A pair of twin tailpipes completes the exclusive look and sound of the new models.
Inside the S63 AMG, drivers are greeted by an AMG sport steering wheel with distinctive aluminium shift paddles and AMG multi-contour leather sport seats finished in special cross piping. Completing the interior package is an exclusive analog clock modelled on the design of the “IWC-Ingenieur” series in the centre of the dashboard.
Race-Car Suspension and Brakes for the Road
The S63 AMG suspension and brake systems are designed for high-performance driving. AMG makes good use of the Mercedes-Benz Active Body Control (ABC), tuning it for even flatter cornering and less body movement when accelerating and braking.
A Sport-Comfort-Manual button on the centre console allows the driver to choose between three different transmission shift programs that also fine-tune accelerator pedal response and the sport suspension spring-shock settings.
A new twin sliding caliper is used for the front brakes. This new technology combines the performance of a large fixed caliper with the distinct advantages of a floating caliper – lower heat transfer to the brake fluid and better ride comfort. Large composite brake discs also help ensure short stopping distances even during high-speed driving.
The S63 AMG sedan comes with 20-inch staggered-width AMG light alloy wheels, 8.5 inches wide in front and 9.5 inches at the rear, wearing low-profile 255/35 (front) and 275/35 (rear) tires.
V12 Power for the New-Generation S-Class
Turning to the V12-powered half of the new-generation S-Class family, the S600 marks the renaissance of the legendary 600-Class “Grand Mercedes.” Fitted with greater levels of wood and leather trim, the new V12-powered flagship comes with virtually all S-Class options as standard equipment, including DISTRONIC PLUS with Park Assist, infrared Nightview Assist, Keyless Go, rear view monitor, Active Body Control (ABC), 18-inch forged alloy wheels, four heated and multi-contour front and rear seats, four-zone climate control, and an integrated hands-free communication system with voice control.
Twin-Turbo V12 Engine
Powered by a twin-turbo V12 engine that generates 510 horsepower and an astonishing 612 lb.-ft. of torque, the new S600 model blends the whisper-smooth performance of the flagship Mercedes-Benz four-door sedan with the astonishing power of a twin-turbo V12 engine. At the same time, the bi-turbo V12 comes clothed in luxury, convenience and refinement that define the market segment.
The 60-degree V12 engine provides effortless thrust with turbine-like smoothness, featuring a vast torque band with peak torque beginning as low as 1,800 rpm. With the high-tech engine, Direct Select five-speed transmission and state-of-the art aerodynamics, the new S600 can reach 100 k/h in 4.4 seconds, quicker than many sports cars. To handle the torque of the V12 engine, transmission planetary gear sets have been widened, and the input and output shafts adjusted accordingly.
AMG-Developed V12 Powers World’s Most Powerful Four-Door
The S65 AMG blends the whisper-smooth performance of the flagship Mercedes-Benz four-door sedan with the astonishing power of AMG’s six-litre twin-turbo V12 engine. The AMG engine makes 604 horsepower and 738 lb.-ft. of torque, for 0-100 km/h test track times of about 4.4 seconds, making it the world’s quickest four-door sedan. AMG is the renowned high-performance division of Mercedes-Benz that combines its ingenuity and performance tuning expertise with the global technology resources and car-building expertise of Mercedes-Benz to take engine, braking and handling performance technology to the highest level.
AMG designers made subtle enhancements to the S65 AMG body while remaining true to the car’s fundamental design. First, an AMG front apron with large cooling air intakes and integral front clear-lens fog lamps gives the vehicle a distinctive appearance. The dynamic side view of the S65 AMG is emphasized by AMG side skirts, which follow the line of the front apron, and by a chromed “V12 Biturbo” badge on each front fender. The powerful lines of the AMG rear apron are finished off by two sets of AMG chrome twin tailpipes, and eye-catching 20-inch AMG light-alloy wheels complement the car’s overall appearance, marking the first use of original-equipment 20-inch wheels and tires on a Mercedes-Benz.
Stopping Power to Match Go Power
To handle the high speed potential of the AMG twin-turbo engine, the front brakes of the AMG V12 model are equipped with high-performance dual sliding calipers and compound brake rotors. For the design of the AMG high-performance braking system, engineers drew on their extensive racing experience acquired through more than three decades of motorsports competition. The internally ventilated and perforated front discs measure 390 mm (15.4 inches) in diameter and are fitted with dual-sliding fixed calipers.
The S65 AMG front brakes use two-piece rotors and hubs made from cast iron and aluminium. Compared with conventional brake systems, this compound technology offers a weight saving of some 20 percent, while the brakes’ increased capacity to handle thermal stress measurably increases durability. The rear brakes use 365 mm (14.4-inch) internally ventilated and perforated discs with single-piston sliding calipers.
Staggered-width AMG twin-spoke wheels, 8.5 x 20 inches up front and 9.5 x 20 at the rear, carry high-performance tires – 255 / 35 ZR 20 in front and 275 / 35 ZR 20 at the rear. The new S65 AMG is fitted with a specially modified version of the Mercedes-Benz five-speed automatic transmission.
Active Body Control (ABC)
Mercedes-Benz was the first automaker to develop active-suspension technology for production cars, and both V12-powered S-Class sedans, as well as the V-8 powered S63 AMG, are equipped with Active Body Control (ABC). ABC reduces body roll in cornering, squat under acceleration, and dive during braking.
Mercedes-Benz engineers use its interplay of hydraulic, electronic and mechanical parts to reduce body roll by 68 percent, ensuring that the suspension still provides the driver with feedback through the vehicle chassis, and a switch on the console allows the driver to further reduce body roll by 95 percent.
Reworked Electronic Stability Program (ESP) control and ASR traction control systems complement the enhanced chassis setup. As on all Mercedes-Benz models, standard ABS anti-lock brakes help maintain directional stability when braking and turning, while Brake Assist can reduce braking distances in “panic” stops.
More PRE-SAFE® Features
Standard equipment on all S-Class models, the revolutionary S-Class PRE-SAFE® system that made its debut in 2002 on the S-Class automatically tightens the front seat belts during those valuable seconds just before a possible impact, and the front passenger seat (and optional power rear seats) move to positions that can provide better protection. If the system senses an impending rollover, the sunroof also closes.
On the new-generation S-Class, side windows also close to provide better support for the window curtain air bags, and special seat cushions can inflate to provide greater lateral support for occupants and to help the side air bags provide even better collision protection.
New DISTRONIC PLUS Helps in Stop-and-Go Traffic
The well-known DISTRONIC cruise control feature that maintains a pre-set following distance behind the vehicle ahead is replaced by an optional “DISTRONIC PLUS” system. Integrated with the latest PRE-SAFE, the latest radar-based system operates at nearly all speeds up to 200 km/h and can be especially helpful in stop-and-go traffic. Newly developed short-range radar with a frequency of 24 gigahertz sweeps the first 30 metres in a fan-shaped 80-degree pattern, working in tandem with a narrower nine-degree beam of longer-range 77-gigahertz radar.
The two radar frequencies complement each other to cover a full range of more than 140 metres. During approval of the new 24-gigahertz radar frequency, government agencies cited its potential to improve traffic safety, reduce injuries and ultimately save lives.
Radar-Based Park Assist
DISTRONIC PLUS also incorporates 24 GHz radar-based Park Assist. This new option utilizes six radar sensors mounted behind the front and rear bumpers – eliminating the need for the visible “portholes” of the previous ultrasonic-based system. The result is clean, integrated and invisible, with greater range and sensitivity.
Brake Assist Now Teams Up With DISTRONIC PLUS
In the early 1990s, Mercedes-Benz engineers conducting simulator tests discovered that many drivers don’t push the brake pedal hard enough in emergency braking, a discovery that led to the development of Brake Assist, standard equipment on all Mercedes-Benz vehicles since late 1990s. Brake Assist has proven itself a million times over, and tests show that vehicles equipped with Brake Assist are involved in 26 percent fewer accidents!
Making its debut on the new-generation S-Class, an enhanced version of the Mercedes-Benz Brake Assist system not only supplies appropriate braking assist in emergencies as soon as the driver applies the brake pedal, but also measures the distance to the vehicle ahead (thanks to DISTRONIC PLUS) and adjusts brake pressure if the driver doesn’t brake hard enough. While conventional Brake Assist is only triggered by the driver’s reflex reaction on the brake pedal, Brake Assist Plus also considers the closing speed of the vehicle ahead based on radar signals from the DISTRONIC PLUS system.
Brake Assist Plus Can Reduce Rear Collisions by 75 Percent
In extensive tests conducted by Mercedes researchers using 300 drivers, the new integrated system reduced rear collisions in heavy city traffic by 75 percent. During testing, data recorders and video cameras documented more than 250,000 real-world miles covered by 200 drivers in the U.S. and Europe, while 100 drivers participated in months of intense testing on the Daimler driving simulator in Berlin.
Infra-Red Night View Assist
Another innovative technology making its debut on the 2007 S-Class is Night View Assist, a new option that can extend the driver’s ability to see ahead more than 150 metres. In contrast to passive systems that rely only on thermal imaging, this active system bathes the road ahead with invisible infra-red light from two projector beams mounted in the headlights. An infra-red camera discreetly mounted in the windshield receives the reflected images and displays them in a high-resolution display in the instrument cluster. The result is akin to a highly detailed black & white video image.
Among the advanced features of the car is a slot in the dash that accepts a PCMCIA card. Such cards never need to be charged, and some versions can hold up to 1500 digital songs. Its data be displayed on the screen of the COMAND system, and titles can be selected through the multifunction steering wheel controls.
Newly developed front seats are electrically adjustable 16 ways and offer several optional choices of ventilation and ergonomic adjustability. The available Drive Dynamic seats feature 11 individual pneumatic chambers to help the driver find a perfect seating position, and 14 more chambers provide four levels of pulsating massage to relieve fatigue and help keep drivers alert.
