Safety Comparison

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 Quattroporte 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 Quattroporte doesn’t offer inflatable seatbelts.

The S-Class has standard PRE-SAFE Brake, 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 Quattroporte doesn't offer collision warning or crash mitigation brakes.

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 Quattroporte doesn’t offer a night vision system.

The S-Class’ optional 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 Quattroporte 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 Quattroporte 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.

The S-Class’ optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. The Quattroporte doesn’t offer a system to reveal objects in the driver’s blind spots.

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 Quattroporte 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 Quattroporte doesn’t offer a driver alert monitor.

The S-Class has standard mbrace, 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 Quattroporte 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 Quattroporte have standard driver and passenger frontal airbags, front 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 and rearview cameras.

Warranty Comparison

There are almost 6 times as many Mercedes dealers as there are Maserati dealers, which makes it much easier should you ever need service under the S-Class’ warranty.

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 Quattroporte doesn’t offer an automatic engine start/stop system.

Brakes and Stopping Comparison

For better stopping power the S-Class’ brake rotors are larger than those on the Quattroporte:

S550

S63/S65

Quattroporte S

Quattroporte GTS

Front Rotors

14.6 inches

16.5 inches

14.2 inches

15 inches

Rear Rotors

The S-Class S63/S65 offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Quattroporte doesn’t offer ceramic brake rotors.

Tires and Wheels Comparison

For better traction, the S63/S65’s front tires are larger than the largest tires available on the Quattroporte (F:255/40R20 & R:285/35R20 vs. F:245/40R20 & R:285/35R20).

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available 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 Quattroporte doesn’t offer run-flat tires.

Suspension and Handling Comparison

The front and rear suspension of the S-Class uses air springs for a smoother, controlled ride than the Quattroporte, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

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

The S-Class has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Quattroporte doesn’t offer a load leveling suspension.

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 Quattroporte doesn’t offer drift compensation steering.

Chassis Comparison

The design of the Mercedes S-Class amounts to more than styling. The S-Class has an aerodynamic coefficient of drag of .24 Cd. That is significantly lower than the Quattroporte (.31) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the S-Class get better fuel mileage.

Passenger Space Comparison

The S-Class has 1.1 inches more front headroom, 1.4 inches more rear headroom and 3.8 inches more rear shoulder room than the Quattroporte.

Cargo Capacity Comparison

With its sedan body style and remote trunk release lockout, the S-Class offers cargo security. The Quattroporte’s non-lockable folding seat and non-lockable remote release defeat cargo security.

A standard locking glovebox keeps your small valuables safer in the S-Class. The Quattroporte doesn’t offer locking storage for small valuables.

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

Ergonomics Comparison

Unlike the driver-only memory system in the Quattroporte, the S-Class has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The S-Class offers an optional heads-up display which projects speed readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The Quattroporte doesn’t offer a heads-up display.

If the windows are left down on the S-Class the driver can raise them all using the key in the outside lock cylinder or the keyless remote; on a hot day the driver can lower the windows. The driver of the Quattroporte can only operate the windows from inside the vehicle, with the ignition on.

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 Quattroporte doesn’t offer heated windshield washer fluid. It’s standard heated washer nozzles will defrost the washer fluid but not the windshield.

To better shield the driver and front passenger’s vision, the S-Class has standard dual-element sun visors that can block glare from two directions simultaneously. The Quattroporte doesn’t offer secondary sun visors.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the S-Class has standard extendable sun visors. The Quattroporte doesn’t offer extendable visors.

To keep a safe, consistent following distance, the S-Class has a standard Distronic Plus, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Quattroporte doesn’t offer an adaptive cruise control.

The S-Class’ optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Quattroporte doesn’t offer an automated parking system.

Recommendations Comparison

The Mercedes S-Class won two awards in Kiplinger’s 2015 car issue. The Maserati Quattroporte didn't win any award.

J.D. Power and Associates rated the S-Class first among large premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Quattroporte isn’t in the top three.

The S-Class was chosen as one of Automobile Magazine’s “All Stars” for 3 of the last 16 years. The Quattroporte has never been an “All Star.”
