The new Mercedes CL63 AMG

Increased performance and torque, reduced fuel consumption and exhaust emissions - these qualities are perfectly united in the new Mercedes-Benz CL63 AMG's 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.

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 Mercedes-Benz 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.

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.

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.

Well, I do like the 4.4L Turbo V8 and the N54 is pretty sweet. However, I do not like how BMW, which I remember reading like 7 years ago that they considered turbos as "shortcuts", is pretty much gonna make turbos for just about every engine if the trend continues.

And as for AMG, only the V12s should have turbos. They either need to further develop the NA engines or bring back their superchargers.

It’s a shame that so many great car which had great naturally aspirated engines are going turbo just because of emissions.

The turbocharged straight six is indeed an excellent piece of engineering. It's smooth, fast, powerful, quite economical and it has little turbo lag. However, it still isn't as satisfying as a proper normally apsirated engine. Those have a wider powerband, a better sound and a more satisfying character.

Yet another worthless post from our sales flier guy. Again he didn't include a link to the article thus likely violating a copyright laws.

Thickness abounds. Peepul mone cuz yu havnt posted even one ov yor brochures az yet.

100 posts to date, 10% of which are idiotic polls.

Look: we understand you're 13... but get with the program. Don't cut 'n paste another piece without attribution, understand? You claim to collect automobile brochures? Let's see them. Moreover... please clearly express WHY you collect them, WHAT value their content is to you, HOW they may be of interest to the online community. Instead of scattering them under individual threads, start a thread specifically FOR your brochure collection as others have done in providing a useful contribution to this site.

You know those red squiggly lines underneath your words when you type? You don't want those. Right-click and select the right word.

Do we moan? We only moan because you keep asking us the same questions without even bothering to spell the words right. I don't remember seeing any brochure scans.
