(from Daimler press
release) New powertrain with the AMG 5.5-litre V8 biturbo
engine: Higher performance, lower consumption – the new S 63 AMG and
CL 63 AMG with an output of up to 420 kW (571 hp)
Exciting cutting-edge
technology from Affalterbach: the Mercedes-Benz S 63 AMG and the CL
63 AMG are to benefit from a completely newly developed powertrain.
The AMG 5.5-litre V8 biturbo engine with a peak output of up to 420
kW (571 hp) and a torque of up to 900 Nm, in combination with the
unique AMG SPEEDSHIFT MCT 7-speed sports transmission, contributes
towards a considerable reduction in consumption and emissions, while
at the same time increasing maximum power and torque. With a fuel
consumption of 10.5 litres per 100 kilometres (NEDC combined), the
new high-performance cars not only undercut their direct competitors
– they are also more than 25 percent more economical in terms of
their fuel consumption than the previous models with naturally
aspirated V8 engine.
The Mercedes-Benz CL 63
AMG also features a new cutting-edge look: thanks to a new design
the Coupé has an even more athletic and confident appearance. The
inclusion of the Direct-Steer system, Torque Vectoring Brake and
crosswind stabilisation as standard has resulted in another leap
forward in terms of agility and active handling safety. New optional
extras now available include Active Lane Keeping Assist and Active
Blind-Spot Assist. The exclusive V12 models - the S 65 AMG and CL 65
AMG - now produce 463 kW (630 hp) instead of the previous 450 kW
(612 hp).
The S 63 AMG and CL 63
AMG mark the start of a new chapter in the "AMG Performance 2015"
drive strategy: Mercedes-AMG is continuing this impressive story and
is meeting its promise to continuously reduce both the fuel
consumption and emissions of new models with the new
engine/transmission combination – while also reaching new heights
with the central AMG brand value of "performance".
According to Ola
Källenius, head of Mercedes-AMG GmbH: "We are heading into a new era
with the S 63 AMG and CL 63 AMG: for the first time we have combined
spray-guided direct petrol injection with biturbocharging and the
start/stop system. Together with the AMG SPEEDSHIFT MCT 7-speed
sports transmission, we have reduced both fuel consumption and
emissions significantly – while at the same time increasing output
and torque."
Together with the unique
AMG SPEEDSHIFT MCT 7-speed sports transmission, the new AMG
5.5-litre V8 biturbo engine will play a significant role in the
Mercedes-AMG model strategy over the coming year. The new engine /
transmission combination marks a further milestone in the successful
history of Mercedes-AMG, which began back in 1967.
Direct petrol injection with
spray-guided combustion and biturbocharging
Designated internally as
the M 157, the new V8 engine is a prime example of efficiency and
features a whole host of impressive technological highlights: for
the first time AMG is taking advantage of direct petrol injection
with spray-guided combustion and piezo injectors. This technology
enables improved fuel economy thanks to higher thermodynamic
efficiency, which in turns leads to lower exhaust emissions. AMG has
combined the spray-guided combustion with biturbocharging. Other
highlights of the innovative, original eight-cylinder engine from
Affalterbach include full aluminium crankcase, four-valve technology
with variable intake valve timing, air/water charge air cooling,
generator management and also standard Controlled Efficiency
start/stop function. Compared with the AMG 6.3-litre naturally
aspirated V8 engine with a displacement of 6208 cc, the new AMG
5.5-litre V8 biturbo engine achieves all this with a displacement of
5461 cc.
This high-tech package
leads to a high output and torque yield, together with fuel
consumption figures that are unrivalled in the competitive line-up.
The AMG 5.5-litre V8 biturbo engine develops a peak output of 400 kW
(544 hp) and maximum torque of 800 Nm. In conjunction with the AMG
Performance package these figures are increased to 420 kW (571 hp)
and 900 Nm. A look at the performance diagrams shows that no other
engine in this output class achieves the figures delivered by the
new AMG biturbo. The major difference between the two performance
classes is an increase in the maximum charge pressure from 1.0 to
1.3 bar. In addition, the engine cover of models with the AMG
Performance package comes in high-quality carbon fibre.
Quantum leap: fuel consumption
reduced by more than 25 percent
With an NEDC fuel
consumption of only 10.5 litres per 100 kilometres, the S 63 AMG and
CL 63 AMG are 3.9 litres more economical than the preceding models
powered by the naturally aspirated AMG 6.3-litre V8 – despite an
increase in output of 14 kW (19 hp) resp. 34 kW (46 hp) and in
torque of 170 and 270 Nm. Engine specialists consider this achieved
fuel saving of more than 25 percent to be nothing less than a
quantum leap. CO2 emissions have likewise been significantly
reduced: at 244 grams per kilometre, the figure is almost 30 percent
lower than for the previous model. Both performance variants have
identical fuel consumption and CO2 figures. As such, the new AMG
models are not only considerably better than all their competitors,
but also more fuel-efficient than much less powerful cars in this
segment.
Sports car-level performance
At the same time the S
63 AMG and CL 63 AMG deliver superior performance at sports car
level: both V8 models accelerate from zero to 100 km/h in 4.5
seconds, and have an electronically limited top speed of 250 km/h.
The 100 km/h mark is reached in just 4.4 seconds with the AMG
Performance package, with the top speed increased to an
electronically limited 300 km/h.
It is not only the
unrivalled torque delivery of this turbocharged eight-cylinder that
makes the heart beat faster, as the agile responsiveness with no
irritating charger delay leads to an effortlessness and dynamism
previously unknown in this output class. All perfectly matched by
the powerful, sonorous engine note. Moreover, this AMG
high-performance engine naturally meets all the requirements with
respect to smooth, quiet running and the comfort on long journeys
that is to be expected of a Mercedes.

AMG SPEEDSHIFT MCT 7-speed sports
transmission
Power is transferred by
the AMG SPEEDSHIFT MCT 7-speed sports transmission used exclusively
by AMG, which is already familiar from the SL 63 AMG and E 63 AMG
and combines high emotional appeal with outstanding driving
dynamics, impressive comfort and a high level of efficiency. The wet
start-up clutch replaces a conventional torque converter, and helps
to save fuel. The exemplary fuel economy is also in large measure
due to the standard start/stop function. This system is active in
the transmission's Controlled Efficiency ("C") mode, and switches
the eight-cylinder engine off when the car comes to a stop. In "C"
mode the sports saloon and coupé always start off in second gear,
and the transmission shifts to the next, higher gears at a decidedly
early stage. With its high torque at low engine speeds, the V8
engine encourages a smooth, effortless driving style.
The eight-cylinder
biturbo engine also features the generator management system
familiar from the E 63 AMG: whenever the engine is on the overrun or
when braking, kinetic energy is used to charge the battery rather
than being wasted as heat in the usual way. In all other operating
modes a combination of onboard network and generator management
enables the generator to be kept at a low voltage. This reduces the
load on the engine and makes for fuel savings of around 0.15 litres
per 100 kilometres according to the NEDC standard, and up to 0.2
l/100 km in city traffic with its frequent overrun and braking
phases.
Engine production – tradition of
hand-built excellence
Like all other AMG
engines, the new eight-cylinder biturbo unit is assembled by hand in
the AMG engine shop in Affalterbach. Highly-qualified technicians
assemble the M 157 according to the "one man, one engine"
philosophy, maintaining the very strictest quality standards. This
painstaking care is attested to by the signature on the
characteristic AMG engine plate.
Long tradition of powerful AMG V8
engines
Powerful eight-cylinder
engines are an inseparable part of AMG's corporate history.
Established in 1967, the company immediately caused a stir with the
300 SEL 6.8 AMG which succeeded in taking second place at the
24-hour races at Spa-Francorchamps (Belgium). The AMG racing saloon
was technically based on the Mercedes-Benz 300 SEL 6.3. With an
engine output of 184 kW (250 hp) at 4000 rpm and a top speed of 220
km/h, this luxury V8 saloon was Germany's fastest regular production
car at the time. Classic tuning as well as an enlarged displacement
from 6330 to 6835 cc resulted in an increase in output to 315 kW
(428 hp) at 5500 rpm and in torque from 500 to 608 Nm.
A further milestone in
the AMG engine story was the M 117, the first eight-cylinder unit
with four-valve technology. With a displacement of 5.6 litres, 265
kW (360 hp) and 510 Nm of torque, this V8 accelerated the
Mercedes-Benz 300 CE 5.6 AMG to a top speed of 303 km/h in 1987.
This made the coupé the fastest German car in series production, and
American fans reverently christened it "The Hammer".
Another important engine
in the history of AMG was the supercharged AMG 5.5-litre V8
introduced in 2001: the M 113 K developed an output of up to 428 kW
(582 hp) and torque of 800 Nm. The supercharged AMG 5.5-litre V8 in
the SLR McLaren of 2003 was even more powerful – the M 155 developed
up to 478 kW (650 hp) and 820 Nm. 2005 saw the debut of the AMG
6.3-litre V8 engine; depending on the model, the naturally
aspirated, high-revving M 156 developed up to 386 kW (525 hp) and
630 Nm. Exclusively reserved for the new SLS AMG, the likewise
6.3-litre M 159 has a maximum output of 420 kW (571 hp) and maximum
torque of 650 Nm.
Numerous victories in the
"International Engine of the Year Awards"
The supercharged AMG
5.5-litre V8, the AMG 6.3-litre V8 and the AMG 6.0-litre V12 biturbo
were all able to win the Best Performance Engine category in the
International Engine of the Year Awards. The AMG 6.3-litre V8 also
won in 2009 and 2010 in the "Above 4 litres" class.
CL 63 AMG with new look and attractive standard equipment
The new CL 63 AMG now
has an even more athletic and confident appearance. The bonnet,
headlamps, radiator grille, bicolour tail lamps and the newly
designed AMG bodystyling all add more dynamism. The "V8 BITURBO"
lettering on the front mudguards also makes for an eye-catching
touch. Also featuring a new look are the AMG triple-spoke
light-alloy wheels, painted in titanium grey and with a high-sheen
finish, and fitted with 255/40 and 275/40 R 19 tyres. New in the
interior are the AMG sports steering wheel with silver-coloured
aluminium shift paddles and specially shaped grip area covered with
perforated nappa leather, as well as the "AMG V8 BITURBO" start
screen in the AMG instrument cluster. As a new optional extra,
SPLITVIEW is also available for the COMAND multimedia system.
With immediate effect,
standard equipment on the CL 63 AMG now includes the Direct-Steer
system, Torque Vectoring Brake and crosswind stabilisation. With its
variable ratio depending on steering angle, the Direct-Steer system
helps to ensure a more direct response when cornering, and therefore
more responsive handling – in brief: enhanced driving pleasure at
the wheel of the Mercedes-AMG CL-Class. Thanks to brief direct
application of the brakes on the vehicle's inner rear wheel when
cornering, the Torque Vectoring Brake, meanwhile, helps to ensure
that the V8 coupé corners precisely and under control at all times.
The Torque Vectoring Brake is an additional feature of the
Electronic Stability Program ESP® and not only noticeably improves
responsiveness but also active handling safety in critical
conditions.
The AMG sports
suspension based on Active Body Control (ABC) now also provides
crosswind stabilisation as an additional function: thanks to this
feature, influences caused by crosswinds are compensated for, or –
in the case of strong gusts – reduced to a minimum. ABC compensates
against the effect of crosswinds by adjusting the wheel load
distribution within milliseconds, using the yaw-rate and lateral
acceleration sensors of the ESP®.
