2006 Mercedes-Benz R Class SLE V6 Convertible

Vehicle Overview Mercedes-Benz unveiled a brand-new model at the 2005 New York Auto Show. The automaker says the R-Class grand sports tourer is the company's first model to blend the merits of a sport utility vehicle, sports sedan and luxury wagon. Two trim levels are available: the R350, equipped with a V-6 engine and the R500, powered by a V-8. A seven-speed-automatic transmission works with an all-wheel-drive system. Evolved from Mercedes' Grand Sports Tourer concept of 2000, the production model hasn't changed much according to Ron Mueller, the company's manager of luxury sport utility touring. Marketers are promoting the R-Class for its style, sophistication, luxury and spacious six-passenger capacity. Exterior Front and rear design cues are modeled after Mercedes-Benz coupes and sedans. Rounded and squat at the rear, the new model flaunts a relatively long profile. The unibody R-Class wagon is about an inch longer than Mercedes' flagship S-Class sedan. Two distinct sunroofs are optional: a conventional glass panel or a double-sized panoramic unit with a 5-foot-7-inch glass panel. When opening the panoramic sunroof, half of the panel moves atop the other so headroom isn't affected. Powered roller blinds in this roof protect occupants from the sun. Privacy glass is standard, and a single-lift tailgate is installed. The R-Class' fully independent suspension uses double wishbones up front and a four-link setup at the rear. Seven-spoke aluminum-alloy wheels hold 17-inch tires on the R350, and the R500 rides on 18-inch rubber. AMG 19-inch wheels are also available, and a Saks Fifth Avenue Signature Edition gets a unique set of wheels. A load-leveling rear air suspension is standard, and the driver can select from three operating modes: Normal, Comfort or Sport. Dealer-installed roof rails are available. Interior The R-Class provides space for up to six occupants courtesy of three pairs of seats. Space between the first and second row measures 34 inches, with 30 inches between the second and third row. There's enough space between the second-row seats to walk through to the third row, and individual seats in both rear rows can be folded. An optional second-row console contains additional cupholders, and bottle holders are located in each door pocket. The seats have leather inserts, and brown birds-eye maple wood trims the doors, dashboard and center console. The four-spoke multifunction steering wheel features brushed-aluminum accents, and a new electronic gear selector is mounted on the steering column. The upper section of the two-tone dashboard arches over the instrument cluster, which holds two cylindrical binnacles for the speedometer and tachometer. Weather-band reception is included in the standard radio, which has a single-CD slot and controls for optional satellite radio. An auxiliary plug in the glove box connects to MP3 players. Optional flat-screen monitors built into the back of the front head restraints can provide entertainment for rear passengers. Under the Hood A 3.5-liter V-6 in the R350 develops 268 horsepower and 258 pounds-feet of torque. The R500's 5.0-liter V-8 produces 302 hp and 339 pounds-feet of torque. Both engines team with a seven-speed automatic. The transmission is able to skip as many as three gear ratios during downshifts to get the transmission in the proper gear. All-wheel drive includes three differentials. Safety Side curtain-type airbags protect occupants in all three rows of seats, and door-mounted side-impact airbags for front occupants are standard. A rollover sensor can activate seat belt pretensioners and the side curtain-type airbags. Antilock brakes and an Electronic Stability Program are standard, and a tire-pressure monitoring system is installed. Driving Impressions The refined, versatile, luxurious R-Class yields a lush ride even when surfaces get rough. Few drivers could ask for a more satisfying luxury tourer for long hauls. Handling is no less impressive. Steering feels just
