Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Porsche Panamera have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW M5 doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Porsche Panamera are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW M5 doesn’t offer height-adjustable seat belts.

The Panamera offers all wheel drive to maximize traction under poor conditions, especially in ice and snow. The M5 doesn’t offer all wheel drive.

Both the Panamera and the M5 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Suspension and Handling Comparison

The Panamera offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. BMW doesn’t offer an active suspension on the M5.

The Panamera has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Panamera’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The M5 doesn’t offer a load leveling suspension.

For better handling and stability, the average track (width between the wheels) on the Panamera is 1.2 inches wider in the front and 3 inches wider in the rear than the track on the M5.

The Panamera Turbo 4 handles at .97 G’s, while the M5 pulls only .91 G’s of cornering force in a Car and Driver skidpad test.

The Panamera goes through Road & Track’s slalom faster than the M5 (71.2 vs. 71 MPH).

The Panamera Turbo 4 executes Motor Trend’s “Figure Eight” maneuver quicker than the M5 (24.4 seconds @ .81 average G’s vs. 25.2 seconds @ .78 average G’s).

For better maneuverability, the Panamera S E-Hybrid’s turning circle is 2.3 feet tighter than the M5’s (39 feet vs. 41.3 feet). The Panamera’s turning circle is 2 feet tighter than the M5’s (39.3 feet vs. 41.3 feet).

Chassis Comparison

The Porsche Panamera may be more efficient, handle and accelerate better because it weighs up to about 450 pounds less than the BMW M5.

As tested by Road & Track while at idle, the interior of the Panamera Turbo 4 is quieter than the M5 (51 vs. 52 dB).

Passenger Space Comparison

For enhanced passenger comfort on long trips the Panamera’s available rear seats recline. The M5’s rear seats don’t recline.

Ergonomics Comparison

The Panamera 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 M5 doesn’t offer a remote starting system.

The Panamera’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The M5 does not have an oil pressure gauge.

To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The M5 doesn’t offer a rear wiper.

The Panamera offers an optional 115 volt a/c outlet in the center console, allowing you to recharge a laptop or run small household appliances without special adapters which can break or get misplaced. The M5 doesn’t offer a house-current electrical outlet.

Economic Advantages Comparison

The Panamera will cost the buyer less in the long run because of its superior resale value. Kiplinger’s estimates that the Panamera will retain a greater percentage of its original price after three and five years than the M5.
