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 M3 doesn’t offer pretensioners for the middle seat belts.

The AMG E 63’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The M3 doesn’t offer pre-crash pretensioners.

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 M3 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 M3 doesn’t offer inflatable seatbelts.

The AMG E 63 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The M3 doesn’t offer all-wheel drive.

To help make backing safer, the AMG E 63’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 M3 doesn’t offer a cross-path warning system.

The AMG E 63’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 M3 doesn’t offer a driver alert monitor.

Both the AMG E 63 and the M3 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available lane departure warning systems.

The Mercedes AMG E 63 weighs 867 to 1150 pounds more than the BMW M3. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.


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.


The AMG E 63’s 4.0 turbo V8 produces 178 more horsepower (603 vs. 425) and 221 lbs.-ft. more torque (627 vs. 406) than the M3’s standard 3.0 turbo 6 cyl. The AMG E 63’s 4.0 turbo V8 produces 159 more horsepower (603 vs. 444) and 221 lbs.-ft. more torque (627 vs. 406) than the M3 Competition Package’s standard 3.0 turbo 6 cyl.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the AMG E 63’s fuel efficiency. The M3 doesn’t offer a system that can shut down part of the engine.

The AMG E 63 has 5.3 gallons more fuel capacity than the M3 (21.1 vs. 15.8 gallons), for longer range between fill-ups.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG E 63 higher (5 out of 10) than the BMW M3 (3). This means the AMG E 63 produces up to 16.5 pounds less smog-producing pollutants than the M3 every 15,000 miles.


The Mercedes AMG E 63 comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the M3.

A nine-speed automatic is standard on the Mercedes AMG E 63, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the M3.

To facilitate fast shifting and allow the driver to focus on the road, the AMG E 63 has a standard up-shift light to indicate when the engine is approaching redline. The M3 doesn’t offer an up-shift light.

Brakes and Stopping

Tires and Wheels

For better traction, the AMG E 63 has larger tires than the M3 (F:265/35R20 & R:295/30R20 vs. F:255/40R18 & R:275/40R18).

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 M3’s standard 40 series tires.

For better ride, handling and brake cooling the AMG E 63 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the M3.

Suspension and Handling

The front and rear suspension of the AMG E 63 uses air springs for a smoother, controlled ride than the M3, 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 M3 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 M3 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the AMG E 63’s wheelbase is 5 inches longer than on the M3 (115.7 inches vs. 110.7 inches).

For better handling and stability, the track (width between the wheels) on the AMG E 63 is 2.7 inches wider in the front than on the M3.

The AMG E 63 S Sedan handles at 1.01 G’s, while the M3 pulls only .97 G’s of cornering force in a Car and Driver skidpad test.


To almost totally eliminate engine vibration in the passenger area, the AMG E 63 has an electronically controlled liquid-filled main engine mount. A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The M3 uses conventional solid rubber engine mounts.

The design of the Mercedes AMG E 63 amounts to more than styling. The AMG E 63 has an aerodynamic coefficient of drag of .32 Cd. That is lower than the M3 (.34) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the AMG E 63 get better fuel mileage.

As tested by Car and Driver, the interior of the AMG E 63 S Sedan is quieter than the M3:

Passenger Space

Because it has more passenger and cargo room, the EPA rates the AMG E 63 Sedan a Mid-size car, while the M3 is rated a Compact.

The AMG E 63 Wagon has standard seating for 7 passengers; the M3 can only carry 5.

The AMG E 63 Sedan has 2.7 inches more front shoulder room, .5 inches more rear headroom, 1.1 inches more rear legroom and 2 inches more rear shoulder room than the M3.

Cargo Capacity

To make loading and unloading groceries and cargo easier, especially for short adults, the AMG E 63 has a standard power trunk, which opens and closes automatically by pressing a button or just by kicking your foot under the back bumper, completely leaving your hands free. The M3 doesn’t offer a power trunk, so its trunk has to be closed manually.

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 M3 doesn’t offer a remote starting system.

Unlike the driver-only memory system in the M3, the AMG E 63 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 63’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The M3 doesn’t offer an easy entry system.

The AMG E 63’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 M3’s passenger windows don’t open or close automatically.

Standard air-conditioned seats in the AMG E 63 keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The M3 doesn’t offer air-conditioned seats.

To keep a safe, consistent following distance, the AMG E 63 offers an optional Distronic Plus, 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 M3 doesn’t offer an adaptive cruise control.

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 M3 doesn’t offer a house-current electrical outlet.

Model Availability

The Mercedes AMG E 63 comes in sedan and station wagon bodystyles; the BMW M3 isn’t available as a station wagon.
