Compare the2025 BMW 5 SeriesVS 2024 Mercedes E-Class Sedan

The BMW 5 Series 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 E-Class Sedan doesn’t offer a front passenger side knee airbag.

The 5 Series’ 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 E-Class Sedan.

Both the 5 Series and the 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, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.

The BMW 5 Series achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The E-Class Sedan has not yet been evaluated by the IIHS for 2024.

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

BMW pays for scheduled maintenance on the 5 Series 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 E-Class Sedan.

J.D. Power and Associates rated the 5 Series second among upper midsize premium cars in their 2024 Initial Quality Study. The E-Class Sedan isn’t in the top three in its category.

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.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that BMW vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks BMW 20 places higher in reliability than Mercedes.

The 5 Series has more powerful engines than the E-Class Sedan:

As tested in Car and Driver the 530i 2.0 turbo 4-cylinder hybrid is faster than the E 350 Sedan 2.0 turbo 4-cylinder hybrid:

On the EPA test cycle the 5 Series running its gasoline engine gets better mileage than the E-Class Sedan:

To lower fuel costs and make buying fuel easier, the BMW 5 Series uses regular unleaded gasoline (premium recommended for maximum performance). The E-Class Sedan requires premium, which can cost on average about 84.9 cents more per gallon.

The 5 Series stops shorter than the E-Class Sedan:

For better traction, the 5 Series has larger standard tires than the E-Class Sedan (245/45R19 vs. 225/55R18). The 5 Series’ optional tires are larger than the largest tires available on the E-Class Sedan (F:255/35R21 & R:285/30R21 vs. F:245/45R19 & R:275/40R19).

The 5 Series’ standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the E-Class Sedan’s standard 55 series tires.

For better ride, handling and brake cooling the 5 Series has standard 19-inch wheels. Smaller 18-inch wheels are standard on the E-Class Sedan.

The 5 Series offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the E-Class Sedan; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the E-Class Sedan don’t have a run-flat feature, either.

For a smoother ride and more stable handling, the 5 Series’ wheelbase is 1.3 inches longer than on the E-Class Sedan (117.9 inches vs. 116.6 inches).

The front grille of the 5 Series uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The E-Class Sedan doesn’t offer active grille shutters.

The 5 Series is available in both rear-wheel drive and all-wheel drive configurations. The E-Class Sedan doesn’t offer a two-wheel drive configuration.

The BMW 5 Series outsold the Mercedes E-Class/CLS by 31% during 2023.
