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 Portofino 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 Portofino 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 Portofino 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 Portofino 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 Portofino 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 Portofino 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 Portofino 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 Portofino only offers 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 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 Portofino 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 Portofino 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 Portofino 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 Portofino have standard driver and passenger frontal airbags, front side-impact airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and front and rear parking sensors.

The AMG S-Class Cabriolet’s 4.0 turbo V8 produces 12 more horsepower (603 vs. 591) and 103 lbs.-ft. more torque (664 vs. 561) than the Portofino’s 3.9 turbo V8.
On the EPA test cycle the AMG S 63 Cabriolet gets better fuel mileage than the Portofino (15 city/24 hwy vs. 16 city/22 hwy).
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 Portofino 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 seven-speed automatic is available for the Portofino.
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 Ferrari Portofino is not available with all wheel drive.
For better stopping power the AMG S-Class Cabriolet’s brake rotors are larger than those on the Portofino:
In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The AMG S-Class Cabriolet has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Portofino doesn’t offer a brake assist feature.
For better traction, the AMG S-Class Cabriolet has larger front tires than the Portofino (F:255/40R20 & R:285/35R20 vs. F:245/35R20 & R:285/35R20).
The front and rear suspension of the AMG S-Class Cabriolet uses air springs for a smoother, controlled ride than the Portofino, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.
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 Portofino 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 Portofino doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the AMG S-Class Cabriolet’s wheelbase is 10.8 inches longer than on the Portofino (115.9 inches vs. 105.1 inches).
To make loading groceries and cargo easier when your hands are full, the AMG S-Class Cabriolet’s trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Portofino doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.
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 Portofino doesn’t offer a remote starting system.
Unlike the driver-only memory system in the Portofino, 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 Portofino doesn’t offer a heads-up display.
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 Portofino 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 Portofino doesn’t offer automatic dimming high beams.
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 Portofino 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 Portofino.
For greater rear passenger comfort, the AMG S-Class Cabriolet has standard rear a/c vents to keep rear occupants more comfortable. The Portofino doesn’t offer rear vents.
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 Portofino doesn’t offer an adaptive cruise control.
The AMG S-Class Cabriolet’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Portofino doesn’t offer an automated parking system.
