Affalterbach – Sensational appearance, unique performance data, with
light-weight design throughout and total exclusivity - that's the new
Mercedes-Benz SL 65 AMG Black Series. This high-performance coupé is a
motorsport engineering thoroughbred, opening up new drive dynamic vistas to
sports car enthusiasts. The AMG 6.0 litre V12 biturbo engine, with a maximum
output of 493 kW/670 hp and 1000 Newtonmetres of torque, guarantees super sports
car level performance. The powerful two-seater was developed in the AMG
PERFORMANCE STUDIO and represents the continuation of the highly
successful Black Series strategy pursued by AMG, the Mercedes-Benz Cars
Performance brand.
Broad, muscular and ready to pounce - that's the new Mercedes-Benz SL 65 AMG
Black Series. Even when stationary, the coupé'ssuperlative dynamism can
arouse great passions. The strikingly broad mudguards, the retractable rear
spoiler and the rear apron with diffuser fins point unmistakably to its
motorsport origins, part of the Mercedes-AMG corporate philosophy for more than
40 years. One glance at the new SL 65 AMG Black Series and you are
reminded of the successful AMG racing sports cars like the present DTM C-Class
or the 1997 CLK-GTR from the FIA-GT series.
Wide cooling air apertures in the front apron and the bonnet are the clearest
indication of the massive power of this AMG twelve-cylinder, biturbocharged
engine. From its 5980 cubic capacity, the AMG V12's engine generates a maximum
power of 493 kW/670 hp at 5400 rpm and an electronically limited torque of 1000
Newtonmetres between 2200 and 4200 rpm. Without a limiter, the AMG 6.0 litre V12
biturbo engine, which is hand-built in the AMG engine factory in accordance with
the "one man – one engine" philosophy, would achieve a maximum torque of 1200
Newtonmetres. Compared with the basis power pack in the 450 kW/612 hp SL 65 AMG,
new turbochargers were developed for the twelve-cylinder SL 65 AMG Black
Series engine. The turbochargers' spiral cross-section, now twelve per cent
larger, and the optimised wastegate ducts permit increased air throughput and an
even more impressive display of power in all engine speed ranges. The modified
intake air ducting results in an even more spontaneous response. The new design
for the AMG sports exhaust gas system's rear silencers reduce the exhaust gas
backpressure and help increase the power output. The acoustic side effect of
this is to produce a distinctive twelve-cylinder sound, typically evocative of
AMG engine tuning, from the two trapezoidal tail pipes. The low-temperature
charge air cooler, now 30 per cent more powerful, and the optimised water
cooling system guarantee not only that the power generated under extreme dynamic
driving conditions is exploited to the maximum but also the greatest possible
fatigue strength at high outside temperatures.
Unique performance thanks to attractive power-to-weight
ratio
The extraordinary engine specifications, which make the SL 65 AMG Black
Series the most powerful AMG model yet, help to produce unique performance
data: from a standing start, it takes just 3.9 seconds to reach 100 km/h; top
speed is 320 km/h (electronically limited). The most important data are
summarised below:

Equally responsible for its excellent dynamics is the attractive
power-to-weight ratio of only 2.79 hp/kg, resulting from the comparably low
unladen weight of 1870 kilograms, according to EU standard measurement. This
makes the SL 65 AMG Black Series some 250 kilograms lighter than the SL
65 AMG - a respectable weight saving due specifically to the use of lightweight
construction. Numerous bodywork components are made of high-strength and
particularly light carbon fibre composites (CFRP), a well-proven motorsports
technology. The 14 centimetre wider front mudguard, the front apron with the
visible carbon front splitter, the bonnet and the boot lid are all made from
CFRP. Large apertures in the bonnet ensure that excess heat is reliably ducted
away from the engine. "V12 Biturbo“ lettering on the front mudguards gives an
indication of the engine's power.
New CFRP roof with integral roll-over bar
The whole CFRP roof shell has taken on a completely new design. Not only does
it now have an integral roll-over bar but, by no longer having the typical SL
vario roof installed, the roof line has a significantly flatter profile. This is
also evident from a glance at the bigger rear window, now placed at a less sharp
angle to the boot lid. The CFRP rear spoiler, concealed in the boot lid,
automatically extends twelve centimetres at 120 km/h, effectively reducing the
lift force on the rear axle at high speeds. Looked at from the rear, the
conspicuous feature is the new rear apron with its visible carbon diffuser.
Concealed within it is the active cooling system for the rear axle locking
differential. New, weight-optimised, twin-spoke design, AMG forged alloy
wheels - 19 inch wheels at the front and 20 inch at the rear - impressively
occupy the whole of each wheel housing. With their black paintwork, high-sheen
surface and matt finish, they lend a note of extravagance to the side profile.
Power transmission with double-declutch function and four
transmission modes
Matching the outstanding performance potential and the versatile drive
dynamics, the SL 65 AMG Black Series also displays its power pack and
suspension at their best. An AMG SPEEDSHIFT PLUS five-speed automatic gearbox
transmits power to the rear wheels. There is a choice between four transmission
modes: "C", "S", "M1" and "M2" which has gearshift times 25 per cent quicker
than the "M1" mode. The torque converter's lockup clutch guarantees extremely
direct gearshifting in all driving situations right from first gear. The
automatic double-declutch function not only makes shifting down a more
pleasurable task, it also ensures that the load alteration effect is
reduced.
AMG adjustable coil spring sports suspension and 3-stage
ESPÒ
As for the suspension, the AMG experts have put their trust in a new design.
The AMG sports suspension has been designed on adjustable coil spring lines;
this well-proven motorsports solution allows the shock absorbers' rebound and
compression stages, the ride height, wheel alignment and camber to be adjusted.
This means that the driver can adjust the suspension to suit his own personal
specifications when driving on racing circuits. The spring links, camber struts
and pull/push rods on both axles are new developments and each axle has a
weight-optimised aluminium wheel carrier. Compared with the standard SL 65 AMG,
the Black Series front axle track width is 97 millimetres wider and the
rear axle track width 85 millimetres wider. The new front axle kinematics
produce an 8 per cent more direct steering ratio; and the completely re-designed
elastokinematics ensure noticeably greater steering precision. A multiple-disc
limited-slip differential on the rear axle with a 40 per cent locking effect
guarantees optimum traction.
The 3-stage sports function ESPÒ is a by-word for maximum driving pleasure
and outstanding drive dynamics: The driver can choose between "ESP ON", "ESP
SPORT" and "ESP OFF" by pressing the ESPÒ button; the AMG instrument cluster
will then show whichever mode is currently activated on the central display.
Sports tyres and composite disc brakes for best
performance
The wheel-tyre combination chosen is also responsible for a superb
performance by the SL 65 AMG Black Series on racing circuits. 265/35 R
19 tyres are fitted to 9.5 inch wide AMG light-alloy wheels on the front axle.
The impressive format for the rear axle is AMG 11.5 x 20 light-alloy wheels with
325/30 R 20 tyres. Dunlop, DTM's motorsports partner, supplies the "Sport Maxx
GT" sport tyres which provide particularly good grip and permit astonishing
cornering speeds.
The large AMG high-performance brake system can be seen through the filigree
structure of the AMG twin-spoke light-alloy wheels. Internally ventilated and
perforated disc brakes engineered in particularly strong composite materials are
employed all round. On the front axle, braking is undertaken by six-piston fixed
callipers and 390 x 36 mm discs; on the rear axles, this task is carried out by
four-piston fixed callipers and 360 x 26 mm discs.
A functional and lovingly designed interior
Nappa leather, Alcantara and carbon: the interior of the SL 65 AMG Black
Series provides the perfect ambience to set the pulses of sports car
enthusiasts racing. The interior, entirely in black, exudes the functional
atmosphere of a genuine racing sports car while the lovingly designed details
have the power to captivate.
Newly developed AMG sports bucket seats made of CFRP (ECE version only)
provide perfect lateral support for the occupants when taking bends fast. The
seats without side airbags are upholstered in fine-grained nappa leather and
Alcantara with embossed AMG lettering in the head restraints. With its 15
millimetre smaller diameter, flattened lower profile and with both sides
perforated for easier grip, the AMG Performance steering wheel provides maximum
vehicle control. The silver-coloured aluminium shift paddles allow manual gear
selection.
Additional highlights in the centre console are the high-quality carbon trim
parts, the gleaming matt start/stop button, the new selector lever with carbon
inlay and the AMG logo with "Black Series" lettering. Matching features
are the carbon door centre panels with embossed AMG lettering, together with the
roof lining and the A and C-pillars upholstered in Alcantara anthracite. The
AMG instrument cluster is a completely new design. The black speedometer with
its scale reading up to 360 km/h has also been re-designed; and the same is true
of the white rev counter which has four integral LEDs to advise the driver of
the optimum gearshift points.
Exhaustive development in all the world's climate zones
Exhaustive development and testing of the SL 65 AMG Black Series
began in 2006. AMG engineers and technicians test drove ten prototypes and
experimental vehicles in all the world's climate zones. Whether it was fast
circuits of the Nürburgring, high-speed test driving in Nardo (Italy), wind
tunnel testing, intensive test driving in summer heat or the cold of the Arctic
or actual crash testing – the new AMG high-performance coupé had to prove its
production readiness under all conditions. In total, the SL 65 AMG Black
Series was test-driven for roughly 30,000 kilometres on various circuits,
15,000 kilometres of which were on the Nürburgring north loop alone,
acknowledged to be the world's most difficult race circuit.
Like the SLK 55 AMG Black Series and the CLK 63 AMG Black
Series before it, the SL 65 AMG Black Series was also developed in
the AMG PERFORMANCE STUDIO, which opened in 2006. Further information
about the SL 65 AMG Black Series is on the Mercedes-AMG website under
www.mercedes-amg.com. Mercedes-Benz Australia/Pacific has confirmed a limited number will be
coming to Australia, with pricing to be confirmed early 2009.
