Compare the2026 BMW M5VS 2026 Mercedes AMG E-Class Wagon

The BMW M5 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 Wagon doesn’t offer a front passenger side knee airbag.

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 Wagon.

The BMW M5’s optional Surround View offers available integrated front and rear camera washers, ensuring clear, all-weather visibility without the need for manual cleaning. In contrast, the Mercedes AMG E-Class Wagon lacks camera washers, requiring you to manually clean the cameras for optimal performance.

Both the M5 and the AMG E-Class Wagon 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, post-collision automatic braking systems, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The M5’s corrosion warranty is 7 years longer than the AMG E-Class Wagon’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, 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 Wagon.

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 Wagon’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 Wagon’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 Wagon:

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 Wagon doesn’t offer ceramic brake rotors.

For better traction, the M5 has larger front tires than the AMG E-Class Wagon (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 Wagon.

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

For better handling and stability, the track (width between the wheels) on the M5 is 1.4 inches wider in the front and 2.1 inches wider in the rear than on the AMG E-Class Wagon.

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 Wagon doesn’t offer active grille shutters.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the M5 offers cargo security. The AMG E-Class Wagon’s non-lockable folding seat and non-lockable remote release defeat cargo security.

A power rear sunshade is optional in the M5 Sedan and manual rear side window sunshades are optional in the M5 to help block heat and glare for the rear passengers. The AMG E-Class Wagon doesn’t offer a rear sunshade.

The BMW 5 Series outsold the Mercedes E-Class by almost two to one during 2025.
