The front and rear suspension of the AMG E-Class Cabriolet uses air springs for a smoother, controlled ride than the M8, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The AMG E-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 M8 doesn’t offer a load leveling suspension.

The AMG E-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 M8 doesn’t offer drift compensation steering.

Unlike the driver-only memory system in the M8, the AMG E-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 E-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. BMW does not offer a locking feature on the M8’s standard power windows.

In case of a sudden change of weather, the AMG E-Class Cabriolet has a standard remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. The M8 doesn’t offer a remote top, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.

Heated windshield washer fluid is standard on the AMG E-Class Cabriolet to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The M8 doesn’t offer heated windshield washer fluid.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the AMG E-Class Cabriolet has standard extendable sun visors. The M8 doesn’t offer extendable visors.

The AMG E-Class Cabriolet offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the M8.
