The Mercedes W221 is a model that has plenty to offer for the discerning driver which helps it stand out from the competition. For starters, it just oozes comfort, as the soft leather-covered seats can be heated, cooled and massaged by what’s possibly a tiny person hidden under the seat. The car also bears a rock solid road performance with its high-performance engine line up riding on strong acceleration and seamless drivability. Finally, in terms of safety features, the W221 rules with its suite of active and passive safety systems provides both high level of security for drivers and passenger. That made for a better driving experience in turn, resulting from the tangible gains in performance and efficiencies listed above-the combination of which AWD has been especially useful to provide here-and so the 4Matic-ed W221 models were an even wiser investment in automotive design excellence than their predecessors, given the practical benefits.
