Smarter Car Choices!

Overview

Long the choice for buyers seeking solid, unaffable deportment and a distinguished presence, the Mercedes-Benz S-class has become synonymous with power and wealth. Its six-figure starting price certainly plays a part, but it wouldn’t have stayed on top for so long without the class-leading ride and comfort, upscale furnishings, and smooth and muscular powertrains that define it. The latter comes in the form of either a 429-hp turbocharged straight-six, a 496-hp twin-turbo V-8, or a plug-in hybrid that pairs the turbo six with an electric motor. The ride and handling benefit from a standard air-spring suspension, and heated and ventilated massaging front seats coddle the occupants. Well-equipped as standard, there’s also a long list of optional hides, woods, and colours to personalize the S-class to your taste. If there is an area of contention, it’s the sheer number of screens and their almost overwhelming amount of controls and features. Still, while many rivals including the Audi A8, BMW 7-series, and Genesis G90 have made inroads into the big Benz’s turf, for now at least, it remains the king of full-size luxury sedans. As one of our favourites in its segment, the Mercedes-Benz S-class has also earned a spot on our

Specifications of Engine, Transmission, and Performance

Mercedes has the S-class sedan powered by an available 429-hp turbocharged 3.0-liter inline-six-cylinder in the S500, or a 496-hp twin-turbo 4.0-liter V-8 in the S580. Both powertrains are aided by a 48-volt hybrid system and are mated to a nine-speed automatic and 4Matic all-wheel drive. The S580e plug-in hybrid combines an inline-six and an electric motor to  pump out 510 horsepower; all-wheel drive is standard here as well. We’ve luxuriated in the S-class sedan and put our test equipment on every model, all of which have delivered impressive acceleration. While every S-class rides on an air suspension, the optional E-Active Body Control has a “curve” function that subtly leans the car into corners. The S-class can also be equipped with an all-wheel-steering system that makes the big-bodied Merc surprisingly easy to manoeuvre in tight spaces.

Range, Charging, and Battery Life

The EPA estimates the S580e’s electric range should be 46 miles, giving it a lengthy head start before its inline-six engine awakens. However, during our range test, it managed 58 miles. A 9.6-kW onboard charger is standard and is good enough for charging the 22.7-kWh battery at home, but if you’re hoping to quickly juice the battery on a public charger, you should order the optional 60-kW DC charger.

INTERIOR

Desperate to embrace digitisation but knowing it had to retain a familiar and uncompromisingly opulent lounge-like feel, Mercedes-Benz set itself a stern task when it came to developing the cabin of the S-Class.

It has, in the main, succeeded in blending those elements. The surface design of the dashboard is particularly pleasing, and in general the cabin achieves a greater sense of spaciousness than its predecessor but without sacrificing anything in material richness or feelings of all-encompassing solidity and sanctuary. It surpasses the cold ambience of the Audi A8 on every level, does enough to better the beautifully constructed confines of the BMW 7 Series, and gets the better of the Bentley Flying Spur in terms of visibility and airiness, if not tactility and flair. At night, things arguably only get better, when Mercedes’ ambient lighting programme comes to life. It’s a triumph, being configurable for colour and brightness and transforming the cabin into a luxurious and sophisticated cocoon. Heightening the experience are the seats. The deeply bolstered items in the front strike a rare balance of breadth, support and softness, and are among the best in any class of car.

There are also 10 massage programmes. The rear is no less impressive, particularly in LWB cars, which get electric adjustment for the outer seats. A Chauffeur Pack, fitted here, adds deployable footrests and gives the front passenger seat the ability to slide and fold extra far forward. Electric blinds add a further layer of insulation from outside.

Faultless? Not quite. The near-total migration of switchgear onto the central touchscreen makes it more arduous than necessary to alter the climate control settings. Of the physical controls that exist, some also feel cheap. The wing mirror adjusters are one example, the engine start button another.

The size of the display has also necessitated putting the central vents high on the dashboard, out of easy reach, and the door-mounted electric seat controls aren’t hepatically satisfying to touch but strangely stiff and recalcitrant. Small details, admittedly, but ones that take the shine off an otherwise fine and typically lavish effort.
