The 2008 CLS550 Coupe
MSRP $68,375*
Chassis
Front suspension Independent 4-link with antidive geometry and stabilizer bar.
Rear suspension Independent 5-arm multilink with aluminum links and wheel-hub carriers, and geometry for antisquat and alignment control. Stabilizer bar.
Airmatic Dual Control (DC) semi-active air suspension with Adaptive Damping System (ADS-II) Airmatic DC is a semi-active suspension that provides greater ride comfort yet responds to reduce pitch, dive, and roll during braking, accelerating, and cornering by instantaneously firming up spring rates as driving dynamics change. Electronically controlled pneumatic spring-struts integrate variable-rate shock absorbers and coil springs. ADS-II continually optimizes ride and handling by automatically selecting one of four damping profiles for each spring-strut every time a wheel changes its direction of up–down travel. Dual driver-selectable Sport mode engages firmer damping profiles either full-time or at lower thresholds of body movement. Automatic 4-wheel level control includes driver-selectable ride-height control, and automatic vehicle speed-sensitive lowering at higher speeds or when in Sport mode.1
Steering type Rack-and-pinion with vehicle-speed-sensitive power assist and integrated hydraulic damper.
Turning circle 36.7 ft/11.2 m curb-to-curb.
Wheels 18" 7-spoke, 8.5x18 front — 9.5x18 rear.2
Tires Steel-belted radial 245/40 ZR18 front and 275/35 ZR18 rear high-performance.2
Brakes Dual-circuit power-assist 4-wheel disc brakes. 13.0" ventilated front discs. 11.8" ventilated rear discs. 4-piston fixed front and single-piston floating rear calipers.
Adaptive Damping System (ADS-II) Part of Airmatic, the Adaptive Damping System lets you tailor your driving experience with two selectable driving modes - one for sport and one for comfort - at the touch of a button. ADS-II continually optimizes ride and handling by individually adjusting each wheel's shock-absorber rate every time the wheel changes its direction of up-down travel.
Antilock Braking System (ABS) ABS senses impending wheel lockup under heavy braking and pumps the front brakes individually or the rear brakes together (to help maintain stability) as needed up to 30 times per second, to prevent lockup and maintain steering ability. Sensotronic eliminates the pedal pulsation commonly associated with conventional brake systems and ABS.
Brake Assist (BAS) BAS senses emergency braking via the speed at which the driver presses the brake pedal and immediately applies maximum available power boost, potentially reducing the overall stopping distance by eliminating the delay caused by a common human tendency not to brake hard enough, soon enough. Letting up on the brake pedal releases BAS.4
Note: Actual vehicles and specifications may vary.
1. Please obey local speed laws.
2. Lower aspect ratio tires and accompanying wheels provide substantially increased treadwear, increased tire noise and reduced ride comfort. Serious wheel and tire damage may occur if the vehicle is operated on rough or damaged road surfaces or upon encountering road debris or obstacles. These tires are not designed for use on snow and ice. Winter tires mounted on appropriately sized and approved wheels are recommended for driving in those conditions.
3. No system, regardless of how advanced can overcome physics or correct careless driving. Please always wear your seat belt.
4. Braking effectiveness also depends on proper brake system maintenance, and tire and road conditions.
