Compare the2024 Mercedes E-Class SedanVS 2023 Porsche Panamera

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

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 E-Class Sedan are reminded to check the back seat if they opened the rear door before starting out. The Panamera doesn’t offer a back seat reminder.

The E-Class Sedan offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Panamera 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 E-Class Sedan has a standard Maneuvering Brake Function that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Panamera doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the E-Class Sedan. But it costs extra on the Panamera.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The E-Class Sedan has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Panamera doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

The E-Class Sedan has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Panamera’s blind spot costs extra.

To help make backing out of a parking space safer, the E-Class Sedan’s standard Rear Cross-Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Active Brake Assist automatically engages the brakes to help avoid a collision. The Panamera doesn’t offer a rear cross-path warning system.

The E-Class Sedan’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 Panamera doesn’t offer a driver alert monitor.

Both the E-Class Sedan and the Panamera have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available lane departure warning systems.

There are almost 2 times as many Mercedes dealers as there are Porsche dealers, which makes it much easier should you ever need service under the E-Class Sedan’s warranty.

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

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes E-Class Sedan higher (7 to 8 out of 10) than the Porsche Panamera (3 to 5). This means the E-Class Sedan produces up to 30 pounds less smog-producing pollutants than the Panamera every 15,000 miles.

A nine-speed automatic is standard on the Mercedes E-Class Sedan, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Panamera.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The E-Class Sedan has standard Brake Assist to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Panamera doesn’t offer a brake assist feature.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the E-Class Sedan can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Panamera doesn’t offer run-flat tires.

The E-Class Sedan’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 Panamera doesn’t offer drift compensation steering.

The E-Class Sedan is 3.9 inches shorter than the Panamera, making the E-Class Sedan easier to handle, maneuver and park in tight spaces.

The E-Class Sedan has 4 cubic feet more passenger volume than the Panamera (100 vs. 96).

The E-Class Sedan has a much larger trunk than the Panamera with its rear seat up (19.1 vs. 17.6 cubic feet).

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

The E-Class Sedan 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 Panamera doesn’t offer a remote starting system.

The E-Class Sedan’s standard easy entry and exit feature raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Panamera.

If the windows are left open on the E-Class Sedan the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Panamera can only operate the windows from inside the vehicle, with the ignition on.

The E-Class Sedan’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Panamera’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Heated windshield washer nozzles are optional on the E-Class Sedan to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Panamera doesn’t offer heated windshield washer nozzles.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the E-Class Sedan has standard extendable sun visors. The Panamera doesn’t offer extendable visors.

The E-Class Sedan’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Panamera doesn’t offer an automated parking system.

The Mercedes E-Class comes in coupe, convertible, sedan and station wagon bodystyles; the Porsche Panamera isn’t available as a coupe or convertible.

The Mercedes E-Class/CLS outsold the Porsche Panamera by over four to one during 2023.
