Mercedes-Benz S-Class

The S-Class has always been the epitome of an ultra luxury sedan. This redesigned flagship sedan continues to deliver a very comfortable ride but the low profile tires mar it. The cabin is super hushed, fit and finish is impeccable, and thrust is effortless. The standard engine is a 3.0-liter inline-six cylinder, and the uplevel choice is a 4.0-liter V8, both turbocharged. Each is teamed with a nine-speed automatic transmission and supplemented with a 48-volt mild-hybrid system. The car's rear-wheel steering turns the wheels in the direction of travel to aid handling and in the opposite direction to aid maneuverability.

Long considered the benchmark for full-size luxury cars, this version of the Mercedes-Benz S-Class solidly lives up to the model's reputation. The 2014 redesign offered a host of advanced technologies, while upping the luxury ante on many levels. The comprehensive suite of active safety features employs a battery of radar sensors and cameras. Features include active cruise control, lane-keep assist, forward-collision warnings and mitigation, along with attention assist to determine when the driver is drowsy. There is even an optional fragrance dispenser, which operates automatically at pre-determined intervals to keep the interior of the car smelling nice. A coupe version was new for 2015.
