The S-Class’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Mulsanne doesn’t offer pre-crash pretensioners.

The rear seatbelts optional on the S-Class inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The Mulsanne doesn’t offer inflatable seatbelts.

The S-Class has standard NECK-PRO Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO Front Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Mulsanne doesn’t offer a whiplash protection system.

The S-Class has standard Active Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Mulsanne doesn't offer collision warning or crash mitigation brakes.

The S-Class offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Mulsanne doesn’t offer all-wheel drive.

An active infrared night vision system optional on the S-Class helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The Mulsanne doesn’t offer a night vision system.

The S-Class’ lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Mulsanne doesn’t offer a lane departure warning system.

The S-Class offers an optional Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The Mulsanne only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

To help make backing safer, the S-Class’ optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Mulsanne doesn’t offer a cross-path warning system.

The S-Class’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Mulsanne doesn’t offer a driver alert monitor.

The S-Class has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Mulsanne doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the S-Class and the Mulsanne have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems and rearview cameras.

The S-Class comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Mulsanne’s 3-year basic warranty expires 1 year sooner.

The S-Class’ corrosion warranty is 2 years longer than the Mulsanne’s (5 vs. 3 years).

There are over 8 times as many Mercedes dealers as there are Bentley dealers, which makes it much easier should you ever need service under the S-Class’ warranty.

For smoother operation, better efficiency and fewer moving parts, the engines in the S-Class have an overhead cam design, rather than the old pushrod design of the engines in the Mulsanne.

In heavy traffic or at stoplights the S-Class’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Mulsanne doesn’t offer an automatic engine start/stop system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes S-Class higher (3 to 5 out of 10) than the Bentley Mulsanne (1). This means the S-Class produces up to 39 pounds less smog-producing pollutants than the Mulsanne every 15,000 miles.

The EPA certifies the Mercedes S-Class as an “Ultra Low Emissions Vehicle” (ULEV). The Bentley Mulsanne is only certified to “Low Emissions Vehicle” (LEV) standards.

The S-Class’ optional 275/35R20 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the Mulsanne’s optional 40 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the S-Class can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Mulsanne doesn’t offer run-flat tires.

The S-Class offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Bentley doesn’t offer an active suspension on the Mulsanne.

The S-Class’ drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Mulsanne doesn’t offer drift compensation steering.

The S 600 handles at .90 G’s, while the Mulsanne pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

The S 600 executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the Mulsanne (25.8 seconds @ .75 average G’s vs. 26.8 seconds @ .69 average G’s).

For better maneuverability, the S 450/560’s turning circle is 1.9 feet tighter than the Mulsanne’s (40.4 feet vs. 42.3 feet).

The Mercedes S-Class may be more efficient, handle and accelerate better because it weighs about 1050 to 1450 pounds less than the Bentley Mulsanne.

The S-Class is shorter than the Mulsanne, making the S-Class easier to handle, maneuver and park in tight spaces:

S-Class

Mulsanne

SWB Sedan

206.9 inches

219.5 inches

LWB Sedan

215 inches

229.3 inches

For excellent aerodynamics, the S-Class has standard flush composite headlights. The Mulsanne has recessed headlights that spoil its aerodynamic shape and create extra drag.

The S-Class has a much larger trunk than the Mulsanne (18.7 vs. 15.75 cubic feet).

A low lift-over trunk design makes loading and unloading the S-Class easier. The S-Class’ trunk lift-over height is 27.4 inches, while the Mulsanne’s liftover is 29.8 inches.

To make loading groceries and cargo easier when your hands are full, the S-Class’ trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Mulsanne doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

The S-Class has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Mulsanne doesn’t offer a remote starting system.

Heated windshield washer fluid is standard on the S-Class to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Mulsanne doesn’t offer heated windshield washer fluid.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes S-Class has a standard wireless phone charging system (Qi) in the center console and for the rear passengers. The Mulsanne doesn’t offer wireless personal charging.

The S-Class’ optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Mulsanne doesn’t offer an automated parking system.
