Safety Comparison

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 7 Series doesn’t offer height-adjustable seat belts.

Both the Panamera and the 7 Series have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, front seatbelt pretensioners, plastic fuel tanks, four wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all wheel drive.

The Panamera offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The 7 Series doesn’t offer ceramic brake rotors.

Tires and Wheels Comparison

For better traction, the Panamera’s optional tires are larger than the largest tires available on the 7 Series (F:255/40R20 & R:295/35R20 vs. F:245/45R19 & R:275/40R19).

The Panamera S’ standard 275/45R18 rear tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the 7 Series’ standard 50 series tires. The Panamera’s optional 255/40R20 front and 295/35R20 rear tires have a lower 40 series front and 35 series rear profile than the 7 Series’ optional 45 series front and 40 series rear tires.

Suspension and Handling Comparison

For better handling and stability, the average track (width between the wheels) on the Panamera is 1.9 inches wider in the front and .1 inches wider in the rear than the track on the 7 Series.

The Panamera Turbo 4 handles at .97 G’s, while the 750Li pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

The Panamera Turbo 4 goes through Road & Track’s slalom faster than the 750i (69.1 vs. 68.2 MPH).

The Panamera S executes Motor Trend’s “Figure Eight” maneuver quicker than the 750Li (25.7 seconds @ .72 average G’s vs. 26.2 seconds @ .7 average G’s).

For better maneuverability, the Panamera’s turning circle is .7 feet tighter than the 750i’s (39.3 feet vs. 40 feet). The Panamera’s turning circle is 3.4 feet tighter than the ActiveHybrid 750Li’s (39.3 feet vs. 42.7 feet).

Chassis Comparison

The Porsche Panamera may be more efficient, handle and accelerate better because it weighs about 450 to 700 pounds less than the BMW 7 Series.

The Panamera is 4.2 inches shorter than the 750i, making the Panamera easier to handle, maneuver and park in tight spaces.

Cargo Capacity Comparison

The Panamera’s standard rear seats fold to accommodate long and bulky cargo. The 7 Series doesn’t offer folding rear seats, only a ski pass-through.

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 7 Series 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 7 Series has neither an oil pressure gauge nor a temperature gauge.

To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The 7 Series doesn’t offer a rear wiper.

Economic Advantages Comparison

The Panamera will cost the buyer less in the long run because of its superior resale value. The Intellichoice estimates that the Panamera will retain 53.86% to 54.35% of its original price after five years, while the 7 Series only retains 30.11% to 36.64%.

Intellichoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Porsche Panamera will be $2455 to $27199 less than for the BMW 7 Series.
