Mercedes-Benz dresses its E-Class sedan in sleekened sheetmetal and revamps the interior to create the CLS. CLS seats four vs. the E-Class's five, and does not offer all-wheel drive or a wagon body style. It comes as the CLS500 with a 302-hp V8 and as the high-performance CLS55 AMG with a 469-hp supercharged V8. The CLS500 has a 7-speed automatic transmission, the CLS55 a 5-speed automatic. Each has a manual shift gate. Steering-wheel shift buttons are optional on the CLS500, standard on the CLS55. Both have an air-spring suspension that adjusts firmness within three driver-selectable modes. Traction/antiskid control is standard, as is antilock braking via Mercedes' "by-wire" control that can adjust brake pressure for each wheel. The CLS55 adds firmer chassis tuning and cosmetic touches by Mercedes' AMG performance division. An AMG Sport Package for CLS500 includes wider tires and aero body trim. Front and rear side airbags and curtain side airbags are standard. So is a full-length center console and twin bucket-type rear seats. Available are Mercedes' drive-dynamic front seats with air bladders that adjust firmness to match cornering force.
