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, four wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all wheel drive.
J.D. Power and Associates’ 2009 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Porsche second in initial quality. With 22 more problems per 100 vehicles, BMW is ranked 15th.
J.D. Power and Associates’ surveys of the owners of three-year-old cars provide the long-term dependability statistics that show that Porsche vehicles are more reliable than BMW vehicles. J.D. Power ranks Porsche 9th in reliability, above the industry average. With 16 more problems per 100 vehicles, BMW is ranked 15th.
The Panamera Turbo’s standard 4.8 turbo V8 produces 100 more horsepower (500 vs. 400) and 66 lbs.-ft. more torque (516 vs. 450) than the 750i’s standard 4.4 turbo V8.
The Panamera S4/Turbo’s standard fuel tank has 4.7 gallons more fuel capacity than the 7 Series (26.4 vs. 21.7 gallons).
For better stopping power the Panamera Turbo’s front brake rotors are larger than those on the 7 Series:

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.
The Panamera stops much shorter than the 7 Series:

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.
For better handling and stability, the track (width between the wheels) on the Panamera is 1.9 inches wider in the front and .4 inches wider in the rear than on the 7 Series.
The Panamera Turbo 4 handles at .92 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 750Li (69.1 vs. 68.7 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 2.4 feet tighter than the 750Li’s (39.3 feet vs. 41.7 feet).
The Porsche Panamera may be more efficient, handle and accelerate better because it weighs about 600 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.
The design of the Porsche Panamera amounts to more than styling. The Panamera offers aerodynamic coefficients of drag from .29 to .3 Cd (depending on bodystyle and options). That is lower than the 7 Series (.31 to .32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Panamera get better fuel mileage.
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.
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 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 7 Series doesn’t offer a rear wiper.
