The S-class is Mercedes-Benz's flagship sedan, the pinnacle of luxury. Since its 2007 model update, it has sported V-8 and V-12 engines. But upcoming European CO2 regulations caused Mercedes-Benz to explore a lower emission model, hence the S400 Hybrid.

The S-class has picked up some minor styling updates since the 2007 model, such as greater use of LEDs. Note the LED parking lights across the lower intakes.

The power plant, based on a 3.5-liter V-6 engine, uses a mild hybrid system comprised of a 20 horsepower motor and a lithium ion battery pack. The S400 Hybrid represents the first use of lithium ion battery chemistry in a major production hybrid vehicle.

The S-class fits four in extreme comfort, and easily carries five occupants. Rear seat passengers will find plenty of leg room, no matter how far back the front seats are set.

Our car came with this AMG wheel package, which doesn't make a whole lot of sense for the hybrid, and adds almost 6 grand to the price.

The ride quality, on the S400 Hybrid's air suspension, is exceptional. A button takes the car from Comfort to Sport modes, the latter tightening up the suspension and counteracting body roll.

The trunk capacity of the S400 Hybrid is undiminished, as the battery pack is packaged into the engine compartment.

Mercedes-Benz does an excellent job keeping the dashboard simple and clean, even hiding the six-disc CD changer behind a panel.

At slow speeds, the steering feel is over-powered and light, suiting the luxury character of the car. But at high speeds, the steering communicates more road feel.

The adaptive cruise control works exceptionally well, even bringing the car to a full stop when the car ahead comes to a halt. The driver doesn't need to touch the pedals in stop and go traffic.

The speedometer is not a physical gauge, merely an animation, and gets replaced by this view when night vision is activated. The speed indicator is shown along the bottom of the display.
