The 5 Series 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.

The 5 Series Sedan 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 Sedan offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Panamera doesn’t offer backup collision prevention brakes.

The 5 Series Sedan has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Panamera’s blind spot costs extra.

To help make backing out of a parking space safer, the 5 Series Sedan’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Panamera doesn’t offer a cross-path warning system.

The 5 Series 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 5 Series Sedan 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, daytime running lights, lane departure warning systems, rearview cameras and available all wheel drive.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the 5 Series Sedan its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 96 vehicles tested by the IIHS. The Panamera has not been tested, yet.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance.

The Panamera doesn’t offer a brake assist feature.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 5 Series 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 5 Series Sedan 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.

The design of the BMW 5 Series Sedan amounts to more than styling. The 5 Series Sedan offers aerodynamic coefficients of drag from .27 to .29 Cd (depending on bodystyle and options).

The 5 Series Sedan 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.

The 5 Series Sedan’s standard easy entry system raises the steering wheel, 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 5 Series 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 5 Series 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.
