The new CL 63 AMG will celebrate its market launch in September 2010. The vehicle will have a sales price of 135,100 euros (excl. VAT)/160,769 euros (incl. 19% VAT). The AMG Performance package costs 7900 euros (excl. VAT)/9401 euros (incl. 19% VAT).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.
