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 7 Series have child safety locks to prevent children from opening the rear doors. The Panamera offers optional power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The 7 Series’ child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

Both the Panamera and the 7 Series 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, rearview cameras, available crash mitigating brakes, night vision systems, lane departure warning systems, blind spot warning systems and around view monitors.

The battery on the Panamera is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Panamera’s battery 20 to 30 degrees cooler, its life is increased by years. The 7 Series’ battery is in the hot engine compartment.

On the EPA test cycle the Panamera GTS gets better fuel mileage than the M760i xDrive (16 city/23 hwy vs. 13 city/20 hwy).

An engine control system that can shut down half of the engine’s cylinders helps improve the Panamera Turbo/GTS’ fuel efficiency. The 7 Series doesn’t offer a system that can shut down part of the engine.

The Panamera E Hybrid’s standard fuel tank has 9 gallons more fuel capacity than the 7 Series Hybrid’s standard fuel tank (21.1 vs. 12.1 gallons), for longer range between fill-ups. The Panamera’s standard fuel tank has 3.1 gallons more fuel capacity than the 7 Series’ standard fuel tank (23.7 vs. 20.6 gallons).

The Panamera offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The 7 Series doesn’t offer an SMG or a conventional manual transmission.

For better traction, the Panamera has larger standard tires than the 7 Series (F:265/45R19 & R:295/40R19 vs. 245/50R18). The Panamera’s optional tires are larger than the largest tires available on the 7 Series (F:275/40R20 & R:315/35R20 vs. F:245/45R19 & R:275/40R19).

The Panamera’s standard 265/45R19 front and 295/40R19 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the 7 Series’ standard 50 series tires. The Panamera’s optional 275/35R21 front and 315/30R21 rear tires have a lower 35 series front and 30 series rear profile than the 7 Series’ optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the Panamera has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 7 Series. The Panamera’s optional 21-inch wheels are larger than the 20-inch wheels optional on the 7 Series.

For better handling and stability, the average track (width between the wheels) on the Panamera is 2 inches wider in the front and .5 inches wider in the rear than the average track on the 7 Series.

The Panamera 4S handles at 1.01 G’s, while the 745e xDrive pulls only .85 G’s of cornering force in a Motor Trend skidpad test.

The Panamera Turbo executes Motor Trend’s “Figure Eight” maneuver 2.1 seconds quicker than the 745e xDrive (23.9 seconds @ .86 average G’s vs. 26 seconds @ .71 average G’s).

For better maneuverability, the Panamera Executive’s turning circle is 3.3 feet tighter than the 740i’s (38.7 feet vs. 42 feet).

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.
