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

The AMG S-Class Cabriolet has standard front and rear seat side-impact airbags and head airbags, which act as a forgiving barrier between the passengers and the door. Combined with high-strength steel door beams this system increases protection from broadside collisions. The GranTurismo Convertible doesn't offer rear-seat side-impact airbags, only ones for front seat occupants.

The AMG S-Class Cabriolet 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. At the same time the pretensioning seatbelts fire, removing slack from the belts. The GranTurismo Convertible doesn’t offer a whiplash protection system.

The AMG S-Class Cabriolet 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 GranTurismo Convertible doesn't offer collision warning or crash mitigation brakes.

The AMG S-Class Cabriolet has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The GranTurismo Convertible doesn’t offer all-wheel drive.

An active infrared night vision system optional on the AMG S-Class Cabriolet 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 and even aims one of the vehicle’s headlights in the direction of the person or object. The GranTurismo Convertible doesn’t offer a night vision system.

The AMG S-Class Cabriolet’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The GranTurismo Convertible doesn’t offer a lane departure warning system.

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

The AMG S-Class Cabriolet’s 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. The GranTurismo Convertible doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing safer, the AMG S-Class Cabriolet’s 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 GranTurismo Convertible doesn’t offer a cross-path warning system.

The AMG S-Class Cabriolet’s 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 GranTurismo Convertible doesn’t offer a driver alert monitor.

The AMG S-Class Cabriolet 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 GranTurismo Convertible 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 AMG S-Class Cabriolet and the GranTurismo Convertible have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and front and rear parking sensors.

The Mercedes AMG S-Class Cabriolet weighs 523 pounds more than the Maserati GranTurismo Convertible. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

An engine control system that can shut down some of the engine’s cylinders helps improve the AMG S-Class Cabriolet’s fuel efficiency. The GranTurismo Convertible doesn’t offer a system that can shut down part of the engine.

A nine-speed automatic is standard on the Mercedes AMG S-Class Cabriolet, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the GranTurismo Convertible.

All wheel drive, available in the AMG S-Class Cabriolet, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Maserati GranTurismo Convertible is not available with all wheel drive.

The AMG S-Class Cabriolet’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The GranTurismo Convertible doesn’t offer launch control.

The AMG S-Class Cabriolet has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The AMG S-Class Cabriolet’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The GranTurismo Convertible doesn’t offer a load leveling suspension.

The AMG S-Class Cabriolet’s 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 GranTurismo Convertible doesn’t offer drift compensation steering.

The AMG S-Class Cabriolet 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 GranTurismo Convertible doesn’t offer a remote starting system.

Unlike the driver-only memory system in the GranTurismo Convertible, the AMG S-Class Cabriolet 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 AMG S-Class Cabriolet has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GranTurismo Convertible doesn’t offer a heads-up display.

The AMG S-Class Cabriolet’s standard power windows have a locking feature to keep children in the rear seat from operating them, but the driver can still raise and lower all of them with the lock engaged. Maserati does not offer a locking feature on the GranTurismo Convertible’s standard power windows.

The AMG S-Class Cabriolet’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The GranTurismo Convertible’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the AMG S-Class Cabriolet the driver can close them all at the outside door handle or from a distance using the remote.

Keyless-Go standard on the AMG S-Class Cabriolet allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Maserati GranTurismo Convertible doesn’t offer an advanced key system.

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

While driving with high beams on, sensitive light sensors standard on the AMG S-Class Cabriolet detect other vehicles which could be blinded and automatically switch to low beams. The GranTurismo Convertible doesn’t offer automatic dimming high beams.

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

A power rear sunshade is standard in the AMG S-Class Cabriolet to help block heat and glare for the rear passengers. The GranTurismo Convertible doesn’t offer a rear sunshade.

Both the AMG S-Class Cabriolet and the GranTurismo Convertible have standard heated front seats. The AMG S-Class Cabriolet also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the GranTurismo Convertible.

Standard air-conditioned seats in the AMG S-Class Cabriolet keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The GranTurismo Convertible doesn’t offer air-conditioned seats.

On extremely cold winter days, the AMG S-Class Cabriolet’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The GranTurismo Convertible doesn’t offer a heated steering wheel.

The AMG S-Class Cabriolet has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the GranTurismo Convertible.

To keep a safe, consistent following distance, the AMG S-Class Cabriolet offers an optional Active Distance Assist Distronic, 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 GranTurismo Convertible doesn’t offer an adaptive cruise control.

The AMG S-Class Cabriolet’s standard steering wheel mounted cruise control is close at hand. The GranTurismo Convertible’s standard cruise control is on an over-crowded turn signal stalk.

The AMG S-Class Cabriolet has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The GranTurismo Convertible doesn’t offer a house-current electrical outlet.
