Compare the2025 BMW 5 SeriesVS 2024 Porsche Panamera

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 5 Series 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 5 Series has a standard PostCrash iBrake, 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 5 Series has a standard Active Park Distance Control 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 automatic braking for stationary objects directly to the rear.

The 5 Series’ 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 5 Series and the Panamera have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, 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 Panamera has not yet been evaluated by the IIHS for 2024.

BMW pays for scheduled maintenance on the 5 Series for 2 years and 26000 miles longer than Porsche pays for maintenance for the Panamera (3/36,000 vs. 1/10,000).

There are over 76 percent more BMW dealers than there are Porsche dealers, which makes it much easier should you ever need service under the 5 Series’ warranty.

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

On the EPA test cycle the 5 Series running its gasoline engine gets better mileage than the Panamera running its gasoline engine:

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

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 Panamera; it requires you to depend on roadside assistance and your vehicle will have to be towed.

For a smoother ride and more stable handling, the 5 Series’ wheelbase is 1.8 inches longer than on the Panamera (117.9 inches vs. 116.1 inches).

The BMW 5 Series may be more efficient, handle and accelerate better because it weighs about 250 to 400 pounds less than the Porsche Panamera.

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 Panamera doesn’t offer active grille shutters.

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the 5 Series offers cargo security. The Panamera’s hatchback body style, non-lockable folding seat and non-lockable remote release defeat cargo security.

The 5 Series offers a 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.

If the windows are left open on the 5 Series 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 5 Series’ 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.

The BMW 5 Series outsold the Porsche Panamera by over five to one during 2023.
