PHOENIX — The Mercedes S-Class is the world’s best-selling luxury sedan and the latest generation recently introduced as expected is impressive with spectacular new features and amazing technology. Mercedes is offering two versions of the S-Class, the base level S-500 powered by a 430-hp V6 engine or the S-580 reviewed here with a 496-hp bi-turbocharged mild-hybrid drive V8 engine. All-wheel drive is standard on both models. Of course, luxury not horsepower is what the S-Class is all about.
