Compare the2025 Porsche TaycanVS 2025 BMW i7

For enhanced safety, the front and rear seat shoulder belts of the Porsche Taycan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The BMW i7 doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Porsche Taycan 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 i7 doesn’t offer height-adjustable seat belts.

A passive infrared night vision system optional on the Taycan helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The i7 doesn’t offer a night vision system.

Both the Taycan and the i7 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The Taycan has more powerful engines than the i7:

For better stopping power the Taycan CCB’s front brake rotors are larger than those on the i7:

The Taycan 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 i7 doesn’t offer ceramic brake rotors.

The Taycan stops much shorter than the i7:

For better traction, the Taycan’s optional tires are larger than the largest tires available on the i7 (F:265/35R21 & R:305/30R21 vs. F:255/45R20 & R:285/40R20).

The Taycan’s standard 275/45R19 rear tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the i7’s standard 50 series tires. The Taycan’s optional 265/35R21 front and 305/30R21 rear tires have a lower 35 series front and 30 series rear profile than the i7’s optional 40 series front and 35 series rear tires.

For better handling and stability, the average track (width between the wheels) on the Taycan is 1.5 inches wider in the front and 1.2 inches wider in the rear than the average track on the i7.

The Taycan 4S handles at 1.03 G’s, while the i7 xDrive60 pulls only .92 G’s of cornering force in a Car and Driver skidpad test.

The Taycan Turbo S executes Motor Trend’s “Figure Eight” maneuver quicker than the i7 xDrive60 (23.6 seconds @ .87 average G’s vs. 24.5 seconds @ .78 average G’s).

For better maneuverability, the Taycan w/Rear Axle Steering’s turning circle is 3.7 feet tighter than the i7’s (36.7 feet vs. 40.4 feet). The Taycan Cross Turismo’s turning circle is 1 foot tighter than the i7’s (39.4 feet vs. 40.4 feet).

The Porsche Taycan may be more efficient, handle and accelerate better because it weighs about 1000 pounds less than the BMW i7.

The Taycan is 1 foot, 4.8 inches shorter than the i7, making the Taycan easier to handle, maneuver and park in tight spaces.

The Taycan 4x4 is 6.5 inches shorter in height than the i7, making the Taycan much easier to wash and garage and drive (lower center of gravity).

The Taycan has a much larger trunk than the i7 (17.3 vs. 11.4 cubic feet).

The Taycan has a much larger trunk with its rear seat up than the i7 (18.8 vs. 11.4 cubic feet).

The Taycan’s available rear seats fold to accommodate long and bulky cargo. The i7 doesn’t offer folding rear seats, only a ski pass-through.
