MERCEDES-BENZ LAUNCHES WORLD’S QUICKEST FOUR-DOOR CAR
New S65 AMG Sedan Features Six-Liter Twin-Turbo V12 Engine
CHICAGO – Mercedes-Benz is debuting the world’s quickest four-door sedan during
news media activities preceding the opening of the 2005 Chicago Auto Show, open to the
public February 11-20 at McCormick Place. The new S65 AMG melds the whisper-smooth
luxury of the top Mercedes-Benz four-door sedan with the astonishing power of AMG’s six-
liter twin-turbo V12 engine. The AMG engine produces 604 horsepower and an unbelievable
738 lb-ft of torque, for a 0-60 mph time of 4.2 seconds.
AMG is the renowned high-performance division of Mercedes-Benz that combines its
ingenuity and quality with the global resources of Mercedes-Benz to take engine, braking and
handling performance technology to the highest level.
The new S65 AMG joins the S-Class sedan line, which includes three V8 models – the
S430, S500 and S55 AMG – as well as one other V12-powered car, the S600. The S65
AMG sedan is equipped with ABC active suspension that uses special AMG spring struts with
firmer damping. Reworked ESP stability control and ASR traction control systems
complement the enhanced chassis setup. As on all Mercedes-Benz models, a standard ABS
anti-lock brake system helps maintain directional stability in emergencies, while Brake Assist
can reduce braking distances in “panic” stops.
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 eight-piston calipers and compound
brake rotors. Staggered-size AMG twin-spoke wheels – 8.5 x 19 up front and 9.5 x 19 at the
rear – carry high-performance tires – 245/40 ZR 19 in front and 275/35 ZR 19 at the rear.
AMG V12 Engine Rewrites Sedan Performance

While the S65 AMG can accelerate from 0-60 mph in just 4.2 seconds, its super-
smooth V12 power plant is also ideally suited for relaxed cruising as well. The twelve-
cylinder engine of the S65 AMG is hand-assembled at the AMG engine facility using the
“one-man, one-engine” approach – to guarantee the highest standards of quality and
workmanship, each engine is assembled start-to-finish by one AMG engine specialist. This
philosophy is symbolized by an unusual plate mounted on the engine that bears the signature
of the craftsman who assembled the engine.
The S65 AMG’s twin-turbo engine features a number of high-tech modifications over
the standard V12 powerplant: a precision-balanced crankshaft with a longer stroke, larger-
bore forged pistons and an upgraded system for oil-spray cooling and bearing lubrication are
but a few of its technological highlights. The newly designed engine cover is made from
deep-drawn aluminum and carbon-fiber reinforced plastic.
Stopping Power To Match Go Power
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 15.4 inches in
diameter and are fitted with eight-piston fixed calipers. The
S65 AMG front brakes use two-piece rotors and hubs made from cast iron and aluminum.
Compared with conventional brake systems, this compound technology allows for expansion
of the brake discs and offers a weight saving of some 20 percent, while the brakes’ increased
capacity to handle thermal stress measurably increases durability. The rear brakes use 13.7-
inch internally ventilated and perforated discs with four-piston fixed calipers.
Design Distinguishes AMG
Especially in light of the design awards bestowed on the current S-Class since its
launch in 2000, the primary task facing AMG designers was to make subtle enhancements to
the S65 AMG body while remaining true to the car’s fundamental design. First, an AMG front

apron with a large cooling air intake and the 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 is finished off by two sets of AMG chrome twin
tailpipes, and attractive 19-inch AMG light-alloy wheels with twin-spoke design complement
the overall appearance.
ABC Active Suspension
Mercedes-Benz was the first automaker to develop active-suspension technology for
production cars. Today, the Mercedes-Benz S-Class, CL-Class, and SL-Class model lines
offer one of the world’s most advanced active suspension systems, and the new S65 AMG
comes with firmer AMG spring struts.
Reconciling the conflicting goals of dynamic handling and ride comfort, ABC active
suspension uses high-pressure hydraulics, sophisticated sensors, and powerful
microprocessors to adjust suspension response to current driving conditions with split-second
accuracy. ABC active suspension virtually eliminates body roll in cornering, squat under
acceleration, and dive during braking.
While active suspension technology has the potential to actually bank a car into every
turn (like a motorcycle or airplane), 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.

The Mercedes-Benz S-Class makes use of up-front crash sensors to help determine
impact severity and deployment speed of the two-stage front air bags with higher precision
than ever. A sensor in the front passenger seat classifies occupant weight and also helps to
vary front air bag deployment accordingly.
Although frontal collisions are by far the most common type of accident, side impacts
are more likely to cause serious injury. All S-Class sedans come with head-protection curtain
side air bags that span both sides of the car, as well as a side impact air bag mounted in
each door. The curtain air bags deploy like an air mattress to protect the head and shoulders
in a side collision, and work in conjunction with the door-mounted side air bags, which
provide protection for the chest and hip area.
Innovation in Luxury, Too
The overall design theme of the S-Class interior conveys warmth and comfort, from its
standard full leather upholstery to the sweeping lines of the instrument panel. Wood trim is
standard, with burl walnut accompanying dark interiors and chestnut with lighter interior
colors. The S-Class comes with standard pneumatic door- and trunk-closing assists, while
an electronic trunk closer is optional.
Active ventilated seats circulate air through the seat cushion to reduce perspiration in
hot weather. The climate seat also features an active lumbar mode in which air chambers
built into the seatback can be programmed to breathe, inflating and deflating fully about twice
each minute. This slight movement has proven to be an effective orthopedic way to relax the
spine and back muscles.
Mercedes-Benz S65 AMG / 5
