Germans drive very fast on the Autobahn, which is why German cars so deftly blend handling capability and ride quality into a single package – if they want return customers, it is a requirement. The new Mercedes-Benz S-Class will go very fast and feel very capable, but handling is not the standard S550’s forte. The optional Active Body Control suspension feels a bit unnatural at times, the 18-inch 255/45 Continental ContiTouring Contact tires squeal when taxed, and the steering can suddenly stiffen too much when bending into a curve. Technology is not this car’s friend. Good thing this Mercedes produces vault-like silence on the open road, where it’s most comfortable. Note that there is an optional AMG Sport Package available for the S550, including 19-inch wheels and tires and a body kit. The wider rubber should help handling, the body kit not so much.
