The Mercedes-Benz S-class maintains superiority by being the full-size luxury sedan by which all others are judged. The S-class satisfies the tastes of its moneyed clientele with stacks of fine materials, deep-seated comfort, and loads of technology. There are three models, each equipped with standard 4Matic all-wheel drive—the S500, S580, and S580e—each with an exclusive powertrain.
