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 Dawn 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 Dawn doesn’t offer all-wheel drive.

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 Dawn 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 Dawn doesn’t offer a cross-path warning system.

Both the AMG S-Class Cabriolet and the Dawn have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, around view monitors, driver alert monitors and available night vision systems.

On the EPA test cycle the AMG S 63 Cabriolet gets better fuel mileage than the Dawn (15 city/24 hwy vs. 12 city/18 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 Dawn doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the AMG S-Class Cabriolet’s 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 Dawn doesn’t offer an automatic engine start/stop system.

A nine-speed automatic is standard on the Mercedes AMG S-Class Cabriolet, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Dawn.

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 Rolls-Royce Dawn 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 Dawn doesn’t offer launch control.

The AMG S-Class Cabriolet 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 Dawn doesn’t offer ceramic brake rotors.

The AMG S-Class Cabriolet’s 255/40R20 front and 285/35R20 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Dawn’s standard 45 series front and 40 series rear tires.

The Mercedes AMG S-Class Cabriolet may be more efficient, handle and accelerate better because it weighs about 300 pounds less than the Rolls-Royce Dawn.

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 Dawn doesn’t offer a remote starting system.

The AMG S-Class Cabriolet’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car.

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 Dawn doesn’t offer a heated steering wheel.

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 Dawn doesn’t offer a house-current electrical outlet.
