The 7 Series has standard Post-Crash Braking, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 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.

Over 200 people are killed each year when backed over by motor vehicles. The 7 Series offers an optional backup collision prevention system which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The E-Class Sedan doesn’t offer backup collision prevention brakes.

An active infrared night vision system optional on the 7 Series helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then projects the image on the windshield, near the driver’s line of sight. The E-Class Sedan doesn’t offer a night vision system.

Both the 7 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, rearview cameras, driver alert monitors, available all wheel drive and around view monitors.


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

BMW pays for scheduled maintenance on the 7 Series for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the E-Class Sedan.


To reliably start during all conditions and help handle large electrical loads, the 7 Series has a standard 950-amp battery. The E-Class Sedan only offers a 850-amp battery.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the 7 Series’ reliability 41 points higher than the E-Class Sedan.

J.D. Power and Associates rated the 7 Series second among large premium cars in their 2018 Initial Quality Study. The E-Class Sedan isn’t in the top three in its category.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Mercedes vehicles. J.D.

J.D. Power and Associates’ 2018 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 vehicles. J.D. Power ranks BMW 8th in reliability, above the industry average. With 20 more problems per 100 vehicles, Mercedes is ranked 15th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that BMW vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks BMW 9 places higher in reliability than Mercedes.

Fuel Economy and Range

On the EPA test cycle the 740e running on electricity gets better fuel mileage than the AMG E 53 Sedan (62 city/68 hwy MPGe vs. 21 city/28 hwy).

On the EPA test cycle the 740e running its gasoline engine gets better fuel mileage than the AMG E 53 Sedan (25 city/29 hwy vs. 21 city/28 hwy).

On the EPA test cycle the 740i xDrive gets better fuel mileage than the E 450 4MATIC Sedan (20 city/29 hwy vs. 20 city/28 hwy).

The 740e can drive on battery power alone for up to 14 miles. The E-Class Sedan must run its internal combustion engine to move.

Regardless of its engine, regenerative brakes improve the 7 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. Mercedes only offers a regenerative brake system on the E-Class Sedan 53 AMG.


The 7 Series’ launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The E-Class Sedan doesn’t offer launch control.

Car and Driver

Tires and Wheels

For better traction, the Alpina B7’s optional tires are larger than the largest tires available on the E-Class Sedan (F:255/35R21 & R:295/30R21 vs. F:245/40R19 & R:275/35R19).

The Alpina B7’s optional 255/35R21 front and 295/30R21 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 E-Class Sedan’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the Alpina B7 offers optional 21-inch wheels. The E-Class Sedan’s largest wheels are only 19-inches.

The 7 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 models of the E-Class Sedan don’t even offer run-flats.

Suspension and Handling

The 7 Series offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The E-Class Sedan doesn’t offer an active sway bar system.

The front and rear suspension of the 7 Series uses air springs for a smoother, controlled ride than the E-Class Sedan, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The 7 Series offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Mercedes doesn’t offer an active suspension on the E-Class Sedan.

For a smoother ride and more stable handling, the 7 Series’ wheelbase is 10.7 inches longer than on the E-Class Sedan (126.4 inches vs. 115.7 inches).

For better handling and stability, the track (width between the wheels) on the 7 Series is .1 inches wider in the front and 1.5 inches wider in the rear than the average track on the E-Class Sedan.

The Alpina B7 handles at .97 G’s, while the E 300 Sedan 4MATIC pulls only .90 G’s of cornering force in a Car and Driver skidpad test.

The 750i xDrive executes Motor Trend’s “Figure Eight” maneuver quicker than the E 300 Sedan (25.4 seconds @ .75 average G’s vs. 25.8 seconds @ .7 average G’s).


The front grille of the 7 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.

As tested by Car and Driver while under full throttle, the interior of the 750i xDrive is quieter than the E 300 Sedan 4MATIC (72 vs. 76 dB).

Passenger Space

Because it has more passenger and cargo room, the EPA rates the 7 Series a Large car, while the E-Class Sedan is rated a Mid-size.

The 7 Series has 16 cubic feet more passenger volume than the E-Class Sedan (114 vs. 98).

The 7 Series has 2.5 inches more front headroom, 1.4 inches more front shoulder room, .7 inches more rear headroom, 8.2 inches more rear legroom and .6 inches more rear shoulder room than the E-Class Sedan.

For enhanced passenger comfort on long trips the 7 Series’ available rear seats recline. The E-Class Sedan’s rear seats don’t recline.

Cargo Capacity

The 7 Series has a larger trunk than the E-Class Sedan (14 vs. 13.1 cubic feet).


The 7 Series has standard heated front seats. Heated front seats cost extra on the E-Class Sedan. The 7 Series also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the E-Class Sedan.

Optional air conditioned front and rear seats keep the 7 Series’ passengers comfortable and take the sting out of hot leather in summer. The E-Class Sedan doesn’t offer air-conditioned seats in the rear.


Consumer Reports® recommends the BMW 7 Series, based on reliability, safety and performance. The Mercedes E-Class Sedan isn't recommended.
