AMG 5.5-LITER V8 BITURBO ENGINE
Performance, innovation and efficiency in perfect harmony
Increased performance and torque, reduced fuel consumption and exhaust emissions – these qualities are perfectly united in the new AMG 5.5-liter biturbo engine. Mercedes-AMG is confronting the challenges of the future, and demonstrating that dynamic performance can be perfectly combined with fuel economy. The result: a maximum output (with the optional AMG Performance Package) of up to 563 hp and 664 lb-ft of torque.
The new AMG 5.5-liter biturbo engine combines performance, innovation and efficiency to a previously unknown extent. This is made possible by a unique combination of innovative high-tech systems such as direct gasoline injection, twin turbochargers, air/water intercooling and the Controlled Efficiency stop/start function. The 2011 AMG CL models will be in U.S. showrooms this November.
Mercedes-AMG is systematically following the trend towards increasing efficiency: with a displacement of 5461 cc it is precisely 747 cc below the 6208 cc of the naturally aspirated AMG 6.3-litre V8 engine. Nevertheless, it develops more output and torque. The 2011 CL63 AMG develops a peak output of 536 hp and maximum torque of 590 lb-ft. In conjunction with the AMG Performance Package these figures increase to 563 hp and 664 lb-ft. The torque curve in particular shows that no other engine in this power class is able to match the figures delivered by the new AMG biturbo motor.
Despite an increase in horsepower and torque as compared to the naturally aspirated V8, AMG engineers have been able to reduce fuel consumption and CO2 emissions considerably. With an estimated fuel savings of 27 percent, engine specialists consider this to be nothing less than a quantum leap. CO2 emissions have likewise been significantly reduced by approximately 30.
These improvements in efficiency and environmental protection have no negative effects on the car’s performance. On the contrary, as the new AMG 5.5-liter V8 biturbo fully lives-up to AMG’s brand commitment to “performance”: the CL63 AMG accelerates from zero to 60mph in 4.4 seconds, and has a top speed of 155 mph (electronically limited). With the AMG Performance package, the highperformance Coupé reaches the 60 mph mark in 4.3 seconds and reaches a top speed of 186 mph (electronically limited).
Combination of twin turbocharging and direct gasoline injection
Mercedes-AMG is presenting an attractive high-tech package with its combination of biturbo charging and direct gasoline injection with spray-guided combustion. The innovative injection technology brings distinct advantages to fuel consumption and exhaust emissions, thanks to higher thermodynamic efficiency. Particularly fast and precise piezo-electric injectors spray the fuel into the combustion chambers, ensuring a homogenous fuel/air mixture and highly effective combustion. An electric low-pressure pump delivers the fuel from the tank to a high-pressure pump in the trunk with a pressure of 87 psi. The fuel pressure in the highpressure rail is controlled between 1,500 and 3,000 psi on a fully variable and demand-related basis.
Two turbochargers and efficient air/water intercooling
Two turbochargers located next to the cylinder banks supply the eight cylinders with fresh air. At their maximum speed of 185,000 rpm under full load, the two turbochargers force 3,860 lbs into the combustion chambers per hour. The maximum charge pressure is 14.5 lbs, and 18.8 bar with the AMG Performance package. Thanks to their specific, compact construction – the turbine housings are welded to the exhaust manifold – there are significant space advantages and the catalytic converters also heat up more rapidly.
The new AMG V8 is the first turbocharged engine to dispense with the usual blow-off valve. This innovative solution enables the compressor housing to be made extremely compact. To ensure agile responsiveness with no time lag, all the air ducts in the intake tract are as short as possible. The wastegate valve, which reduces the pressure in the exhaust system during negative load changes, is vacuum-controlled via an electropneumatic converter. This allows dethrottling under partial loads, which in turn lowers the fuel consumption.
Like the existing AMG 6.0-litre V12 biturbo engine, the new eight-cylinder directinjection unit uses very efficient air/water intercooling. The low-temperature cooler with its water circulation is space-savingly accommodated within the V of the cylinder banks. It effectively cools down the intake air compressed by the turbochargers before it enters the combustion chambers, and maintains a constantly low intake temperature under full load. A large radiator at the car’s front end ensures metered cooling of the water circulating in the low-temperature circuit. This guarantees a high output and torque yield in all ambient temperatures and operating conditions.
Extremely short charge-air ducting makes for outstanding responsiveness. The stainless steel pressure pipes for the fresh and charge air are produced by the hydroforming process, have a wall thickness of only 0.03 inches and are designed for very low pressure loss.
Aluminum crankcase with Silitec cylinder liners
The crankcase of the new AMG 5.5-liter V8 biturbo engine is made of diecast aluminum. The low (dry) engine weight of just 450 lbs is the result of uncompromising lightweight construction methods, and leads to the car’s very balanced weight distribution. The bearing cover for the main crankshaft bearings is of grey cast iron, and is bolted to the crankcase for high rigidity. Cast-in Silitec cylinder liners ensure that the eight pistons operate with low friction.
Drilled pulsation holes in the crankcase lead to a higher output and fuel savings under partial load: above the bearing blocks there are longitudinally drilled holes which connect adjacent crankcase cavities. Normally the upward and downward movement of the pistons causes air to be forced into and extracted from the sump, which leads to increased internal friction losses and therefore a reduction in output. The pulsation holes prevent this by ensuring effective pressure compensation between the cavities.
The forged crankshaft of high-grade 38MnS6BY steel alloy rotates in five main bearings, has eight counterweights and has been optimized with respect to torsional rigidity, inertia, low rotating masses and a long operating life. A twomass viscous damper mounted at the front reliably eliminates vibrations. Each connecting rod journal on the crankshaft carries two forged, cracked connecting rods. In the interests of low mechanical friction and high wear resistance, the lightweight pistons have a metallic contact surface. Pressure-controlled oil-spray nozzles in the crankcase ensure that the highly stressed piston crowns are efficiently cooled.
Four-valve technology with variable camshaft adjustment
Perfect charging of the combustion chambers is ensured by large intake and exhaust valves, of which there are four per cylinder. The exhaust valves, which are subject to high thermal loads, are hollow and sodium-cooled. Four overhead camshafts operate the 32 valves via low-maintenance, low-friction cam followers. The infinitely variable camshaft adjustment with a range of 40 degrees on the intake and exhaust sides depends on the engine load and engine speed, leading to outstanding output and torque values. This also results in consistent idling at a low speed.
Depending on the engine speed, valve overlap can be varied for the best possible fuel/air supply to the combustion chambers and efficient removal of the exhaust gases. The variable camshaft adjustment is carried out electromagnetically via four pivoting actuators, and is controlled by the engine control unit. The camshafts are driven by three high-performance silent chains, which have considerable advantages in noise comfort compared to cylinder roller chains.
Efficient oil supply and water cooling
Efficient oil delivery under all load and operating conditions is ensured by an oil pump with an electrically controlled compression stage. The oil pressure can be varied between 29 and 48 psi, which has advantages in terms of friction and fuel consumption. An extraction stage integrated into the oil pump for the two turbochargers prevents oil from being mixed into the charge air and exhaust gases, thereby helping to reduce emissions even further. Both the sump and the extraction point have been optimized for maximum lateral acceleration and efficient lubrication. The oil capacity is 11 quarts.
The combined water/oil cooling system is a particularly innovative solution: initially the engine oil only flows through the oil/water heat exchanger. If the cooling performance of the very compact cooler is insufficient, the flow is directed through the external engine oil/air cooler by an oil thermostat. The advantage of this system is that the engine oil warms up (via hot engine coolant) more rapidly. A selectable water thermostat ensures rapid warming of the coolant when starting the engine and driving off.
The engine coolant is cooled using the particularly effective crossflow principle. There is a transverse flow of coolant through both the crankcase and the cylinder heads. Additional cooling slots in the cylinder head ensure more efficient cooling of the combustion chambers, which has advantages during combustion: it enables earlier ignition timings to be chosen without incurring the risk of knocking.
Highly efficient engine electronics for every function
All the engine functions are executed and controlled by a particularly efficient Bosch MED 17.7.3. control unit. This state-of-the-art engine computer not only controls the direct gasoline injection, charge pressure, camshaft adjustment and variable oil supply, but also communicates with all the other onboard control units. The microprocessor has more than 30,000 different parameters and functions stored in its memory, and is able to perform up to 260 million individual operations per second. To reduce the load on the engine control unit, the eight individual ignition coils have an integral electronic module known as an ignition amplifier at each cylinder. These ensure a strong ignition spark at all engine speeds and under all load conditions. Eight highvoltage powerstages are responsible for highly precise fuel distribution to the piezoelectric injectors.
Effective emissions technology with new catalytic converter boxes
The requirements for the exhaust system of the new AMG 5.5-liter V8 biturbo engine were complex: low exhaust emissions, compliance with country-specific standards and a characteristic AMG engine sound. The CL63 AMG complies with all the current EU-5 emission standards, as well as meeting all the requirements of the US market (LEV-II standard, On-Board Diagnosis II and lambda sensor diagnosis).
The turbochargers are welded to the exhaust manifolds, while air gap-insulated manifolds with a wall thickness of only 0.04 inches ensure a rapid catalytic converter response. For efficiency and to save space, this concept has a tandem catalytic converter housing on each side of the vehicle: adjacent to the firewall, two thin-walled ceramic substrates are grouped into each housing. This solution makes the previous, additional underbody catalytic converters unnecessary. The two ceramic substrates differ to ensure rapid and efficient emissions control: the front one is coated with palladium, while the rear one has a bimetal coating of palladium and rhodium. One lambda sensor per row of cylinders is located in front of each catalytic converter housing, and there is a lambda diagnostic sensor between each of the two thin-walled substrates.
The lambda sensors are necessary for demand-related lambda control. In all operating conditions, the components of the intake mixture can be precisely controlled to avoid damaging the catalytic converters. This also benefits fuel consumption under full load, as the mixture can be leaner than in engines without this control system.
Twin-pipe AMG sports exhaust system for a characteristic sound signature
The twin-pipe AMG sports exhaust system has a pipe cross-section of 2.76 inches from the manifolds to the rear silencers. When designing the sound, the aim was to create a perfect synthesis of aggressiveness and the comfort on long journeys that is the hallmark of a Mercedes. The goal of the developers was to achieve an emotional experience when accelerating and rev-matching, but unobtrusiveness at constant speeds. Unpleasant frequencies or droning noises were effectively eliminated during a series of painstaking tests. The sports exhaust system emits a sonorous eight-cylinder sound that is typical of AMG, while the striking chrome twin tailpipes feature a new design.

New design and new high-tech drive system: the Mercedes-Benz CL 63 AMG is to feature a new cutting-edge look as well as state-of-the-art technology. The stylish visual modifications will be accompanied by 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 increase in driving dynamics, while at the same time guaranteeing a respectable reduction in consumption and emissions. With a fuel consumption of 10.5 litres per 100 kilometres (NEDC combined), the new high-performance coupé not only undercuts its direct competitors – it is also 27 percent more economical in terms of its fuel consumption than the previous model with naturally aspirated V8 engine.
The new 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 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 stop/start 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 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 and twin turbocharging
Designated internally as the M157, the new V8 engine is a prime example of efficiency and features a whole host of impressive technological highlights: for the first time Mercedes-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 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 lineup. 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 the CL 63 AMG with the AMG Performance package comes with high-quality carbon-fibre applications.
Quantum leap: fuel consumption reduced by 25 percent
With an NEDC fuel consumption of 10.5 litres per 100 kilometres, the new CL 63 AMG is 3.9 litres more economical than the previous model powered by the naturally aspirated AMG 6.3-litre V8 – despite an increase in maximum power of 14 kW(19 hp) and 34 kW (46 hp) respectively, 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 29 percent lower than for the previous model. Both performance variants have identical fuel consumption and CO2 figures.
With figures like these, the new CL 63 AMG is not only considerably better than all its competitors, but also more fuel-efficient than much less powerful cars in this segment.
Sports car-level performance
At the same time the CL 63 AMG delivers superior performance at sports car level: the Coupé accelerates from zero to 100 km/h in 4.5 seconds, and has 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 also leads to an effortlessness and dynamism previously unknown in this output class. All perfectly matched by the characteristic and 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. It combines high emotional appeal with outstanding driving dynamics and a high level of efficiency. A 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 stop/start 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 coupé always starts 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 a generator management system: 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 litre per 100 kilometres according to the NEDC standard, and up to 0.2 litre per 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 is assembled by hand in the AMG engine shop taken into commission in 2002. Highly-qualified technicians assemble the M157 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.
New AMG triple-spoke light-alloy wheels
In visual terms, the new CL 63 AMG has an even more athletic, 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 mudguards points to the new powertrain. Also featuring a new look are theAMG 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.
Direct-Steer system, Torque Vectoring Brake and crosswind stabilisation
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®.
Based on the ADAPTIVE BRAKE system with large compound brake discs all round, the AMG high-performance braking system continues to set the benchmark for stopping power, sensitivity and fade resistance.
A unique combination of driver-assistance systems
The unique combination of innovative camera and radar-based driver-assistance systems has been enhanced even further with immediate effect with a view to perfecting the vehicle’s active and passive safety. New optional extras now available for the CL 63 AMG include Active Lane Keeping Assist and Active Blind-Spot Assist. Active Lane Keeping Assist comes into play when the CL 63 AMG 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.
Individualisation thanks to AMG Performance Studio and designo
New optional extras from the AMG Performance Studio as well as designo enable the vehicle’s individuality to be enhanced even further.
The exclusive optional extras from the AMG Performance Studio at a glance:
- AMG Performance package: increase in maximum power of 20 kW (27 hp) and maximum torque of 100 Nm, genuine carbon fibre AMG engine cover
