The new Mercedes-Benz CL 63 AMG has an AMG 5.5-litre V8 biturbo engine with a peak output of 400 kW and a torque rating of 800 Nm, in combination with the unique AMG SPEEDSHIFT MCT 7–speed sports transmission
Exciting cutting-edge technology from Affalterbach: the Mercedes-Benz CL 63 AMG will benefit from a newly developed powertrain. The AMG 5.5-litre V8 biturbo engine with a peak output of 400 kW and a torque rating of 800 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 10.6 litres per 100 kilometres (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. Standard features include Active Lane Keeping Assist and Active Blind-Spot Assist.
The exclusive V12 model – the CL 65 AMG – now produces 463 kW instead of the previous 450 kW.
The CL 63 AMG marks 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 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.
Sports car-level performance
At the same time the CL 63 AMG delivers superior performance at sports car level: this model accelerates from zero to 100 km/h in 4.5 seconds, and has an electronically limited top speed of 250 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.
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 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 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 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
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 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 and 630 Nm. Exclusively reserved for the new SLS AMG, the likewise 6.3-litre M 159 has a maximum output of 420 kW and maximum torque of 650 Nm.
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. 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. SPLITVIEW is also standard for the COMAND multimedia system.
With immediate effect, standard equipment on the CL 63 AMG now includes 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®.
Active Lane Keeping Assist and Active Blind Spot Assist
What is a unique combination of innovative camera and radar-based driverassistance systems in this vehicle class has been enhanced even further with a
view to perfecting the vehicle’s active and passive safety. New standard features for the CL 63 AMG include Active Lane Keeping Assist and Active Blind-Spot Assist. The new Active Lane Keeping Assist comes into play when the vehicle unintentionally strays over a solid line on the right or left of a lane or on the outside of a bend. In such cases the Electronic Stability Program ESP® applies the brakes to the wheels on the opposite side of the vehicle to prevent it from unintentionally straying from its lane.
Also new is the Active Blind Spot Assist, which warns the driver by displaying a red warning in the glass of the relevant exterior mirror when it detects that
changing lanes would be too dangerous. If the driver ignores the warning signal and a vehicle in an adjacent lane comes too close, the ESP® takes corrective
action by applying the brakes to the wheels on the opposite side of the vehicle.
AMG high-performance braking system with double floating brake caliper
Based on the ADAPTIVE BRAKE system, the AMG high-performance braking system continues to provide optimum fade resistance, deceleration and sensitivity. The front axle features a double floating brake caliper. This exclusive technology combines the advantages of a sliding-caliper disc brake – reduced heat transfer to the brake fluid and clear advantages in terms of comfort thanks to the brake lining guide mechanism – with the efficiency of an extra large fixed caliper
brake.
