For enhanced safety, the front and middle seat shoulder belts of the Mercedes AMG E 63 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The BMW M5 doesn’t offer pretensioners for the middle seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes AMG E 63 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW M5 doesn’t offer height-adjustable seat belts.

The middle row seatbelts optional on the AMG E 63 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 M5 doesn’t offer inflatable seatbelts.

Both the AMG E 63 and the M5 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors and available lane departure warning systems.


There are over 10 percent more Mercedes dealers than there are BMW dealers, which makes it easier should you ever need service under the AMG E 63’s warranty.

Fuel Economy and Range

On the EPA test cycle the AMG E 63 S Sedan gets better fuel mileage than the M5 (15 city/23 hwy vs. 15 city/21 hwy).

An engine control system that can shut down half of the engine’s cylinders helps improve the AMG E 63’s fuel efficiency. The M5 doesn’t offer a system that can shut down part of the engine.

The AMG E 63 has a gallon more fuel capacity than the M5 (21.1 vs. 20.1 gallons), for longer range between fill-ups.

Tires and Wheels

For better traction and acceleration, the AMG E 63 has larger rear tires than the M5 (295/30R20 vs. 285/40R19).

The AMG E 63’s 265/35R20 front and 295/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the M5’s standard 40 series tires. The AMG E 63’s tires are lower profile than the M5’s optional 35 series tires.

For better ride, handling and brake cooling the AMG E 63 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the M5.

Suspension and Handling

The front and rear suspension of the AMG E 63 uses air springs for a smoother, controlled ride than the M5, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The AMG E 63 has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The AMG E 63’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 M5 doesn’t offer a load leveling suspension.

The AMG E 63’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 M5 doesn’t offer drift compensation steering.

The AMG E 63 S Sedan handles at 1.01 G’s, while the M5 pulls only .98 G’s of cornering force in a Car and Driver skidpad test.

Passenger Space

The AMG E 63 Wagon has standard seating for 7 passengers; the M5 can only carry 5.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than BMW. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 23% lower rating, BMW is ranked 11th.


The AMG E 63 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 M5 doesn’t offer a remote starting system.

The AMG E 63 offers an optional 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 M5 doesn’t offer a house-current electrical outlet.

The AMG E 63’s Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The M5’s automatic parking system requires operating the brakes and transmission to safely park.

Model Availability

The Mercedes AMG E 63 comes in sedan and station wagon bodystyles; the BMW M5 isn’t available as a station wagon.
