Race-bred Braking Power
AMG develops its own high-performance brakes, unique from standard series Mercedes-Benz models. Utilizing the extensive racing and testing
experiences of Mercedes-AMG GmbH, the braking systems are developed to equal the output of an AMG engine.
AMG brakes are equipped with larger diameter rotors as part of a high-performance four-wheel disc system. Braking calipers are also
enlarged with multiple front and rear pistons depending on the AMG model. An example of AMG's high performance braking system can be
found on the SL55 AMG, S55 AMG and CL55 AMG models which feature 14.2 diameter front rotors, 8 piston front calipers, 4 piston rear
calipers, and 4- wheel ventilation. As a designation of their high-performance capability, many AMG brake calipers are decorated with the
Further changes to the braking system include higher capacity brake ventilation augmented by directional air cooling via the AMG front
spoiler. Additional improvements include the reprogramming of the active safety and stability control systems. Both are calibrated to
function with the increased braking power and handling of an AMG.
The Power Behind the Performance
Supercharging is a method of generating a significant increase in horsepower without adding a corresponding increase in engine
displacement. AMG has modified and adopted this technology for its newest generation of V6 and V8 Kompressor engines.
AMG has developed a special Lysholm (helical) supercharger for its 3.2-liter AMG V6 and 5.5-liter V8 engines. The Lysholm supercharger is
based on a two rotor helical design intermeshing an aluminum rotor and Teflon-coated alloy rotor. With less than 0.1 inches clearance
between rotors, this supercharger produces 30% more boost pressure than standard superchargers.
Driven through an electromechanical clutch which engages automatically as power is needed, the AMG supercharger operates at a maximum
boost of 12.8 psi over 20,000 rpm. This boost enables the AMG V6 engine to deliver a specific output of over 100 hp per liter. Intake air
is cooled through an integral air-water intercooler mounted beneath the supercharger in the base of the engine's crankcase. The water
in the intercooler is circulated through a special AMG electrical pump system.
Formula 1 Racing Inspired
From the beginning, AMG has pioneered the development of high-performance automatic transmissions. Our latest version is a heavily
modified, driver-adapted 5-speed automatic.
Known as SpeedShiftTM, the considerable power of an AMG engine is delivered through a driver-adapted 5-speed combining the
convenience of an automatic with the dynamic action and control of a manual transmission.
AMG SpeedShift performs 35% faster, more responsive gear changes, can automatically perform double-downshifts under heavy braking, will
hold a specific gear through hard cornering, and automatically selects the optimum gear to ensure maximum acceleration when overtaking
A lighter torque converter that locks in all forward gears is another innovative feature of SpeedShift. AMG SpeedShift is currently
available on the C32 AMG, SLK32 AMG and the 2003 SL55 AMG, CL55 AMG, and CLK55 AMG Coupe and S55 AMG.
Fingertip manual mode, a Formula 1 style shifting system, is one more feature found on many of AMG's SpeedShift transmissions.
Geared for Performnce
Another example of technology transferred from the racetrack to the Mercedes-AMG transmission is fingertip manual mode. The driver can
make rapid, Formula-1-type gear shifts by pressing either of two steering wheel mounted shift buttons. Press the button on the left side
of the steering wheel to shift down. Press the button on the right to shift up. With fingertip manual mode the driver has full control of
all gear changes and SpeedShift only intervenes when the car comes to a stop in high gear, or to shift up at redline.
All wheels are not the same
AMG light alloy wheels are developed specifically for the high-performance braking, handling and acceleration characteristics of each AMG
AMG starts with a robust design engineering strength, balance and trueness into each wheel. The wheels are rigorously tested for load
bearing and impact resistance.
The heart and soul
At AMG, each engine is a hand-assembled, balanced and blueprinted high-performance version of the already
powerful Mercedes-Benz gasoline engines. AMG takes engine assembly to a high art through the use of balanced
Each engine is assembled by one of a small group of AMG master technicians who complete only two or three
engines per day. All operations are performed by the technician, from short block assembly to cylinder head
and intake system installation. This is the core of the AMG philosophy of "One Person, One Engine".
AMG has the flexibility at its engine assembly area to shift production to any of its engine variants such as
the 3.2-liter Kompressor V6 to the 5.5-liter naturally aspirated and supercharged V8s. All engines are shipped
to final assembly plants such as Sindelfingen (E55/S55/CL55) and Bremen (CLK55/C32/SLK32/SL55) for
installation into individual AMG models. AMG no longer performs vehicle assembly at its development and
headquarters in Affalterbach, Germany, but all engines bearing the AMG name originate from this facility.
Control Means Safety
The suspension of an AMG-Mercedes has to live up to the performance of its lightning-quick engine - a
requirement fulfilled by the stiffer AMG hydraulic shock absorbers and specially developed sport
A Breath of Fresh Air
The concern we put into an AMG engine also applies to what we put into the environment. Every AMG
exhaust system is technically advanced with ceramic firewall catalytic converters and two powerful
metal catalytic converters on the underbody. This sophisticated technology reduces emission levels to
meet the 2005 EU-4 emission requirements.
What is AMG
AMG was founded with a singular purpose: to modify existing Mercedes-Benz automobiles into championship
caliber race cars. What was learned on the track has now made its way into limited production vehicles bearing
the Mercedes-Benz name.
Our passion for the highest standards of automotive performance is shared by those seeking race-level road
performance, luxury and exclusivity. To meet the true driving enthusiast's highest demands, every AMG vehicle
is built to exacting tolerances.
