|  Mercedes-AMG is presenting two powerful eight-cylinder flagship models in the form of the CL 63 AMG and S 63 AMG. Dynamic progress is guaranteed by the 100% Mercedes-AMG developed 6.3-litre V8-engine with a peak output of 386 kW/ 525 hp and 630 newton metres of torque. The exclusive nature of the unique AMG high-performance cars is amply demonstrated by their high-tech appoint-ments: standard equipment includes AMG bodystyling, AMG light-alloy wheels and an AMG sports suspension based on Active Body Control, as well as the AMG high-performance braking system and an AMG-specific interior. The preventive occupant protection system PRE-SAFE® is also included - with the new PRE-SAFE® brake and DISTRONIC PLUS available as options. The CL 63 AMG and S 63 AMG are the current highlights of the 2006 strategic model initiative by Mercedes-AMG - with ten brand-new AMG high-performance cars to date.
The heart of both top-of-the-line eight-cylinder models is the 100% AMG-developed AMG 6.3-litre V8-engine. From a displacement of 6208 cc, this high-revving, naturally aspirated engine delivers an output of 386 kW/525 hp at 6800 rpm and a maximum torque of 630 Nm at 5200 rpm. This gives the AMG powerpack a higher specific output and specific torque than any other series-produced naturally aspirated eight-cylinder engine in the world. Accordingly the eight-cylinder unit from Affalterbach has a fulminating performance potential: both AMG models will accelerate to 100 km/h in 4.6 seconds, and the maximum speed is electronically limited to 250 km/h.
All of the prototypes spotted showed additional signs of AMG tuning with larger wheel-and-tire combinations and more aggressive bodywork. The S63 will probably end up becoming the most popular of the three vehicles, but given that the ML is already on sale with the R-Class expected by the end of the year, it's not clear which one of these AMG rockets will show up first |
