Mercedes-Benz offers new Ride Control suspension on SLS AMG
The flagship
Mercedes-Benz SLS AMG
represents the pinnacle of the company's considerable engineering
prowess. Yet there are always those looking for a little more. And for
such customers, Mercedes has announced a series of new options available
on the Gullwing coupe and its roadster counterpart.
The list includes new wheels and paint finishes (like the Sepang Brown
Metallic pictured above), as well as the company's latest blind-spot
warning system. But the salient point of the announcement (which you can
read in full
after the jump) is the new AMG Ride Control suspension.
Available as a ~$3,000 option over the stock setup, the new adjustable
suspension offers drivers a choice between Comfort, Sport or Sport Plus
settings. Some buyers will invariably revel in the choices, but then as
Lotus founder Colin Chapman once famously quipped, "Make the suspension
adjustable and they will adjust it wrong." Good thing, then, AMG has
taken the guesswork out of the equation.

AMG RIDE CONTROL sport suspension with adaptive damping: New optional extras for the Mercedes-Benz SLS AMG
Groß-Dölln/Affalterbach – The Mercedes-Benz SLS AMG is now even more
attractive and individual. The new high-tech option of the AMG RIDE
CONTROL sport suspension with adaptive damping combines concerted
performance-orientation with optimal comfort on long journeys. Blind
Spot Assist improves active safety on board the gull-wing model. Further
optional features such as AMG 10-spoke forged wheels painted in matt
black, red-painted brake callipers or AMG high-gloss black trim make for
even more exclusivity.
A glance at the centre console of the SLS AMG not only reveals the
stylishly designed, new E-SELECT lever with its embossed AMG emblem, but
also a new shock absorber symbol in the AMG DRIVE UNIT. This key
symbolises the new AMG RIDE CONTROL sport suspension with variable,
electronically controlled damping. Depending on the driving situation,
speed and road surface conditions, this optional system almost instantly
varies the damping characteristics and automatically reduces the body
roll angles. For the driver this means immediate and variable adaptation
between the greatest possible agility and the best possible ride
comfort – for any driving style and route.
Maximum individuality: "Comfort", "Sport" and "Sport plus"
A small key with a major effect: pressing the shock absorber symbol
allows individual, convenient adjustment of the damping characteristics.
There is a choice of three modes: "Comfort", "Sport" and "Sport plus".
The currently selected mode is shown in the AMG main menu.
"Comfort" is automatically active whenever the engine is started, and
provides a sensitive damper responce with comfort-oriented
characteristics. "Comfort" is recommended for cruising at moderate
speeds – e.g. in urban traffic or on motorway sections with speed
restrictions. But even on poor, bumpy road surfaces, "Comfort" mode will
be the first choice of many SLS AMG drivers by virtue of the softer
damper setup.
To select "Sport" mode the key in the AMG DRIVE UNIT is pressed once.
The left control lamp in the key and the AMG main menu display tell the
driver that "Sport" mode has been manually activated. In "Sport" mode
the shock absorbers have a tauter response depending on the driving
situation, which not only ensures better road contact when driving in a
sporty manner, but also more effectively reduces body roll and pitching.
In most driving situations, "Sport" mode provides the best compromise
between satisfactory suspension comfort, low body movements and high
agility.
"Sport plus" is recommended for fast lap times on a race circuit:
apart from higher damping forces, this mode has special control
algorithms configured for a decidedly sporty driving style on uneven
road surfaces. The driver is able to store his personal setup using the
AMG key in the AMG DRIVE UNIT. Sustained pressure on the AMG symbol
stores the currently selected suspension mode and also the selected
transmission mode. As before, the driver has four different transmission
modes available: fuel economy mode "C" (Controlled Efficiency), "S"
(Sport), "S+" (Sport plus) and "M" (Manual). Brief pressure on the AMG
key quickly and conveniently activates the preferred combination.
With immediate effect, the new AMG RIDE CONTROL sport suspension is
available on request for the SLS AMG Coupé and Roadster. Alternatively
the gull-wing model is available with the basic AMG suspension or the
AMG Performance suspension, both without variable damping
characteristics.
Numerous parameters monitored by electronics
The electronic damper control is based on acceleration sensors which
register dynamic vehicle body and wheel movements, both absolutely and
in relation to each other. Other factors relevant to the driving
dynamics, such as drive and braking moments, the steering angle and
lateral/linear acceleration are continuously registered and evaluated.
The current vehicle speed, wheel rotation speeds and selected gear
ratios are also continuously analysed. High-performance control
electronics in permanent dialogue with the engine and transmission
control unit ensure that the forces of the four newly developed shock
absorbers are adapted practically instantly.
Depending on the selected suspension mode, different control
configurations and parameter weightings are active to strike the best
possible balance between comfort and dynamic performance.
Electromagnetically actuated valves in the shock absorbers control the
oil flow between the lower and upper chamber. In "Comfort" mode more oil
flows through the valves, and less in "Sport" and "Sport plus" mode.
Double wishbone suspension of forged aluminium
All four wheels are located on double wishbones with a track rod, a
technology that has proven itself in motor racing right through to
Formula 1. With a double-wishbone axle, the wheel location and
suspension functions remain separate; the spring/damper struts are
supported on the lower wishbone. The double-wishbone concept with its
high camber and track rigidity positively locates the wheel with minimal
elastic movements, providing the driver with an optimum sense of road
contact when driving at the limits.
Wishbones, steering knuckles and hub carriers at the front and rear
are made entirely from forged aluminium – substantially reducing the
unsprung masses; this configuration also notably improves the suspension
response. The long wheelbase of 2680 millimetres not only results in
outstanding straight-line stability but also low wheel load shifts,
significantly reducing the vehicle's tendency to dive and squat when
braking and accelerating. The broad track width – front 1682, rear 1653
millimetres – ensures lower shifts in the wheel loads from the inner to
the outer wheel when cornering, enabling the tyres to retain more grip.
The chosen solution with a front-mid-engine plus transaxle
configuration ensures an ideal front/rear weight distribution of 47 to
53 percent. Mounting the engine behind the front axle has created the
ideal conditions for consummate driving dynamics with precise steering,
first-class agility, low inertia with spontaneous directional changes
and outstanding traction.
Direct steering, differential lock and 3-stage ESP®
The rack-and-pinion steering gear provides a consistently direct
steering feel with a constant mechanical ratio of 13.6:1, in tune with
the high expectations placed on a super sports car. The power steering
provides speed-sensitive assistance and improves feedback for the driver
as the road speed increases: an indispensable factor for high-speed
straight-line driving. Mounting the steering gear in front of the engine
on the integral subframe enables the engine to be set down very low.
The SLS AMG comes with 3-stage ESP® as standard, providing the driver
with access to the three "ESP ON", "SPORT Handling mode" and "ESP OFF"
modes at the touch of a button. In "ESP OFF" mode too, vigorously
operating the brake pedal restores all the normal ESP® functions.
The acceleration skid control (ASR) system's traction logic is active
in all three ESP® modes. If one of the drive wheels starts to spin,
specific brake pressure is applied to improve traction significantly –
especially in conjunction with the standard-fit mechanical multi-disc
limited-slip differential. This means that the engine power is
transferred to the road even more effectively when driving in a
particularly dynamic style.
Blind Spot Assist increases active safety
The new, optionally available Blind Spot Assist is able to increase
active safety. This visual and acoustic warning system uses the
close-range radar sensors of the standard PARKTRONIC system to recognise
vehicles in good time where visibility is restricted. When the system
registers another vehicle in the blind spot, this is indicated to the
driver by a red triangle lighting up in the relevant exterior mirror. An
acoustic warning also sounds if the driver operates the indicators
despite the visual warning.
Blind Spot Assist is operational from a speed of 30 km/h. It monitors
the area around the vehicle to a distance of around 3.5 metres on each
side and three metres beyond the rear. Vehicles in the process of
overtaking are shown immediately when they enter the monitored area of
the difference in relative speeds between the two vehicles is not more
than 16 km/h. Vehicles that have just been overtaken are however shown
with a delay of 1.5 seconds after entering the monitored area, thus
preventing distraction by unnecessary warnings.
New optional appointments for more style and design
Available as an optional extra, the car's visual appearance is
enhanced by weight-optimised AMG 10-spoke forged wheels shod with tyres
in size 265/35 R 19 (front) and 295/30 R 20 (rear). Their matt black
paint finish corresponds perfectly with the high-sheen rim flange.
Optional red-painted brake callipers all-round provide a further visual
highlight.
Single-tone or two-tone designo leather in espresso brown is available
as a new interior colour – this dark shade of brown perfectly matches
the new metallic paint finish AMG Sepang brown. New AMG high-gloss black
trim (optional) is an exclusive alternative to the standard centre
conslole in solid metal or the optional carbon-fibre trim.
