At the entry level of the lineup, the S-Class is offered in S550 guise, with optional 4MATIC adding all-wheel drive. Both of these models are powered by a 449-horsepower 4.7L turbocharged V8 engine mated to 7-speed automatic transmission with paddle shifters. High-performance S63 AMG 4MATIC models pack a 5.5L twin-turbo V8 engine making 577 horsepower and 664 pound-feet of torque.
The S600 Maybach and S65 AMG models get a 6.0L twin-turbo V12 that makes 523 horsepower in the S600 and a whopping 621 horsepower and 738 pound-feet of torque in the S65 AMG. The S600, along with both AMG models, is fitted with a special AMG Speedshift 7-speed automatic transmission.
S-Class Coupes, meanwhile, are offered with the 449-horsepower 4.7L engine from the S550, while AMG variants come with or with the 5.5L twin-turbo or 6.0L V12. Finally, a new S-Class cabriolet is offered with the 449-horsepower V8 and an all-new 9G-TRONIC 9-speed automatic transmission. An AMG variant is available, of course: the S63 4MATIC cabriolet features the 5.5L V8 and an output of 577 horsepower and 664-pound-feet of torque, which is paired with the AMG Speedshift MCT 7-speed transmission.
AMG S-Class models offer the power and performance levels of an exotic sports car in a much more luxurious package, so owners get the same level of interior space and nearly the same comfort as any S-Class.
Magic Body Control is an optional feature in the S-Class; it actually scans the road surface and changes the suspension's settings to suit the kind of surface and your own desired level of comfort and control. MBC works together with the standard Active Damping System and AIRMATIC air suspension.
The S63 AMG gets a special AMG Adaptive Sports Suspension that's tuned to make the most of the all-wheel drive system's capability and this car's more performance-oriented setup. The S65 AMG also adds a sport version of Magic Body Control, but it also comes with a speed-sensitive sports steering with multiple settings and a distinct steering-wheel design. Special 20-inch AMG forged-alloy wheels are included in this model, along with a sport exhaust system with twin tailpipes and an available ceramic high-performance composite braking system.
Both the S63 and S65 AMG add a lithium-ion battery that saves more than 44 pounds and isn't as affected by cold temperatures as a normal car battery. And they both include an Eco Start/Stop feature that allows the engine (in some conditions) to stop automatically at stoplights and then restart when the driver lifts off the brake pedal.
All S-Class models include two high-resolution color screens, with a diagonal measurement of 12.3 inches. On the right are infotainment and comfort functions, while instrument-cluster and driver-specific controls are on the left. Expanded voice entry is now allowed for phone and audio systems, and there's a feature that will read text messages aloud. It also includes a customizable head-up display, and the COMAND infotainment display has now been supplemented with a touch pad.
A Burmester Surround Sound system with optional 3D surround offers a so-called Frontbass system that uses woofers placed in the firewall, eliminating the need to take up door space.
The S-Class continues to have some of the best seats in any vehicle. In sedan versions, the rear seat features a limousine-like ambiance with the optional Executive Rear Seat package, which brings folding tables and upgraded back-seat appointments -- including a backrest angle that's adjustable up to 43.5 degrees. A Plus version of that package even brings an aircraft-style seat with Peltier technology that can keep drinks cool or warm. There's a hot-stone-inspired energizing massage function, with six massage programs, including two that provide warming, and the active seat ventilation system now uses reverse fans to help reduce drafts. Other noteworthy options for interior comfort include the Air Balance Package, which brings ionized air purification and has an active air-perfuming feature.
In addition to regular S-Class equipment, the S65 AMG gets a Napa leather roof liner, leather-lined dash and door panels, extra wood trim and AMG door sill panels with white illumination. The gauge cluster is AMG-specific, with additional round-dial gauges for engine and transmission oil temp.
Personalization options on the AMG models include a carbon fiber package, a wood and Napa leather-wrapped steering wheel, the ceramic-brake upgrade, red brake calipers and special carbon fiber and black piano lacquer trim.
Safety takes center stage in the S-Class, once again. As part of a $2,800 Driver Assistance Package, prospective buyers can add the DISTRONIC PLUS radar-based cruise control, PRE-SAFE autonomous braking; the PRE-SAFE PLUS rear-facing radar warning system; BAS PLUS with Cross Traffic Assist (using stereoscopic cameras to help prevent an accident); Active Lane Keeping Assist; and Active Blind Spot Protection. There's also Night View Assist Plus, a feature that continues to be refined, and uses infrared and camera information to detect animals and people along the road ahead.
The venerable Mercedes-Benz S-Class is available in no fewer than 12 different models across sedan, coupe and convertible body styles. And for soaking in the California sun, it doesn't get much better than the Cabriolet. The sun pours in, I set the massaging seats to "relaxing" and unwind. Bring it on, Bay Bridge toll plaza. Your half-hour wait time and crowded lanes can't ruin my commute.
Mercedes offers V6, V8 and beastly V12 power across the S-Class range, though in the Cabriolet, this eight-cylinder S560 serves as the entry-level model. The S560 ditches the old S550's 4.7-liter twin-turbo V8 in favor of a smaller 4.0-liter unit. But don't worry, the new engine actually makes more power -- 463 horsepower -- and torque remains the same at 516 pound-feet.
Power is sent to the rear wheels through a nine-speed automatic transmission. And with the ability to switch between Eco, Comfort, Sport or Sport+ drive modes, the S-Class can drive with many different attitudes. With a heavy right foot, the Merc responds quickly, rewarding me with a subtle growl from the V8. In Comfort mode, the nine-speed is programed more for my grandma's driving style, but things firm up nicely in Sport and Sport Plus. Still, even at the firmest settings, the ride is tuned more for easy touring than speedy turning. Sure, the S560 Cabriolet can hold its own on twisty roads, but at its heart, this car is a cruiser.
