Speaking of mass: To keep weight to a reasonable level, if you want to call two tons and change reasonable, lightweight construction has been employed throughout, like through the use of full aluminum doors that use deep-drawn aluminum panels with extruded sections; they’re reportedly 50 pounds lighter than conventional steel doors. Panels like the hood, front quarter-panels and trunklid are also aluminum constructs, as well as strategic sections of the underlying chassis itself.
For added safety as you careen down your imaginary autobahn, the CLS63 is available with a pair of new driver aid systems, Active Blind Spot Assist and Active Lane Keeping Assist. The first uses short-range radar to monitor the, yes, blind spots in adjacent lanes. If the car comes too close to a vehicle the system detects, it will actually apply braking force to the wheels on the vehicle’s opposite side via the ESP stability program, creating yaw that counteracts the impending collision. Lane Keeping Assist works in a similar way, first warning the driver of lane departure and then intervening with ESP.
If you feel the need for expanded performance, an AMG Performance package is available. Special engine management increases peak power to 557 hp at 5750 rpm, and torque by about 74 lb-ft. This will knock a tenth or two off the zero to 60 time and possibly tilt the Earth’s axis by a degree or so. The Performance package also includes a carbon-fiber engine cover and carbon trunklid spoiler, red-painted brake calipers and an Alcantara-accented steering wheel. There’s also what’s called the AMG Driver’s Package, which includes participation in the AMG Driving Academy and elimination of the 155-mph speed restrictor, allowing access to the CLS63’s actual top speed of 186 mph.
Do you actually need to drive at 186 mph? And can you legally attempt such a feat on public roads in the United States of America? Of course not, and hell no. But that isn’t saying it wouldn’t be nice to have the capability. You know, in case the need should eventually arise. All in all, the CLS63 AMG seems ideal for just such a prospect.
