The S-Class is brimming with features and qualities that make it stand out among luxury cars. A powerful 4.7-liter turbo V8 provides effortless acceleration and delivered 18 mpg overall in our tests. The S550 brings a whole host of advanced technology, including the ability to follow the road and stop by itself in an emergency. The ride is very plush and steady--the best we've ever tested--and the cabin is ultrahushed. Along with the seats and steering wheel, the door and center armrests are heated as well. Even though the S-Class is large and posh, handling agility is commendable. Many controls are overly complicated, however. A coupe version is available, as is a plug-in hybrid. Reliability has been well below average.
Alert
This vehicle can be outfitted with a semi-autonomous driving package. Consumer Reports believes automakers should take stronger steps to ensure that vehicles with those systems are designed, deployed, and marketed safely. Please heed all warnings, and keep your hands on the wheel.
