The new Mercedes-Benz CL63 with AMG 5.5-liter biturbo engine combines performance, innovation and efficiency. 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.

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. 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.

Mercedes-Benz CL63 AMG use combination of twin turbocharging and direct gasoline injection to 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.

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 new AMG V8 is the first turbocharged engine to dispense with the usual blow-off valve. Like the existing AMG 6.0-litre V12 biturbo engine, the new eight-cylinder directinjection unit uses very efficient air/water intercooling.

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. Cast-in Silitec cylinder liners ensure that the eight pistons operate with low friction. 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.

The oil pressure can be varied between 29 and 48 psi, which has advantages in terms of friction and fuel consumption. The combined water/oil cooling system is a particularly innovative solution: initially the engine oil only flows through the oil/water heat exchanger. A selectable water thermostat ensures rapid warming of the coolant when starting the engine and driving off.

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. This car complies with all the current EU-5 emission standards, as well as meeting all the requirements of the US market.

The twin-pipe AMG sports exhaust system has a pipe cross-section of 2.76 inches from the manifolds to the rear silencers. 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.
