Compare the2025 BMW M5VS 2025 Mercedes AMG E-Class Sedan

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the M5 are reminded to check the back seat if they opened the rear door before starting out. The AMG E-Class Sedan doesn’t offer a back seat reminder.

The BMW M5 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The AMG E-Class Sedan doesn’t offer a front passenger side knee airbag.

The M5 has standard PostCrash iBrake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The AMG E-Class Sedan doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The M5’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the AMG E-Class Sedan.

Both the M5 and the AMG E-Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, rear cross-path warning and driver alert monitors.

The BMW M5 weighs 1146 to 1286 pounds more than the Mercedes AMG E-Class Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The M5’s corrosion warranty is 7 years longer than the AMG E-Class Sedan’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the M5 for 3 years and 36,000 miles. BMW will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the AMG E-Class Sedan.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Mercedes With 28 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks BMW higher than Mercedes.

The M5’s 4.4 turbo V8 hybrid produces 140 more horsepower (717 vs. 577) and 185 lbs.-ft. more torque (738 vs. 553) than the AMG E 53 HYBRID Sedan’s standard 3.0 turbo 6-cylinder hybrid. The M5’s 4.4 turbo V8 hybrid produces 113 more horsepower (717 vs. 604) and 185 lbs.-ft. more torque (738 vs. 553) than the AMG E 53 HYBRID Sedan’s optional 3.0 turbo 6-cylinder hybrid.

For better stopping power the M5’s brake rotors are larger than those on the AMG E-Class Sedan:

The M5 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 AMG E-Class Sedan doesn’t offer ceramic brake rotors.

For better traction, the M5 has larger standard tires than the AMG E-Class Sedan (285/40R20 vs. 265/40R20). The M5’s front tires are larger than the largest tires available on the AMG E-Class Sedan (F:285/40R20 & R:295/35R21 vs. F:265/40R20 & R:295/35R20).

For better ride, handling and brake cooling the M5 has standard 21-inch rear wheels. Smaller 20-inch wheels are standard on the AMG E-Class Sedan.

For a smoother ride and more stable handling, the M5’s wheelbase is 1.7 inches longer than on the AMG E-Class Sedan (118.3 inches vs. 116.6 inches).

For better handling and stability, the track (width between the wheels) on the M5 is 2.2 inches wider in the front and .7 inches wider in the rear than on the AMG E-Class Sedan.

The front grille of the M5 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The AMG E-Class Sedan doesn’t offer active grille shutters.

The M5 has 3.3 inches more front headroom, 1.4 inches more front shoulder room and .5 inches more rear headroom than the AMG E-Class Sedan.
