The 7 Series has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The Taycan doesn’t offer a whiplash protection system.

The 7 Series has standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Taycan doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The 7 Series has standard Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Taycan doesn’t offer backup collision prevention brakes.

To help make backing safer, the 7 Series’ cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Taycan doesn’t offer a cross-path warning system.

The 7 Series’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Taycan doesn’t offer a driver alert monitor.

Both the 7 Series and the Taycan 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, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available all wheel drive and night vision systems.

BMW pays for scheduled maintenance on the 7 Series for 2 years and 26000 miles longer than Porsche pays for maintenance for the Taycan (3/36,000 vs. 1/10,000).

There are over 82 percent more BMW dealers than there are Porsche dealers, which makes it much easier should you ever need service under the 7 Series’ warranty.

The 745e’s maximum driving range in pure electric mode is 16 miles. After it exhausts its pure electric range, the 745e can then continue for 314.6 more miles on its internal combustion engine, while the Taycan has to recharge for 22 minutes for only an 80% charge at a specially configured quick charge station not available in most areas. A full recharge at a conventional charging station can take up to 11 hours.

For more complete vehicle control the 7 Series has a manually controlled automatic, with the available convenience of an automatic transmission and the complete gear control of a manual transmission without the inconvenience of a clutch. A manually controlled automatic allows the driver to eliminate unwanted shifts and maximize engine braking by down shifting while cornering. The Taycan doesn’t offer a transmission that allows complete gear control.

An eight-speed automatic is standard on the BMW 7 Series, for better acceleration and lower engine speed on the highway. Only a 2-speed automatic is available for the Taycan.

For better traction, the 7 Series has larger standard tires than the Taycan (245/50R18 vs. 225/55R19).

The 7 Series’ standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Taycan 4S’ standard 55 series front tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the 7 Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Taycan doesn’t offer run-flat tires.

The 7 Series offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Taycan; it requires you to depend on roadside assistance and your vehicle will have to be towed.

The 7 Series has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The 7 Series’ 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 Taycan doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the 7 Series’ wheelbase is 12.2 inches longer than on the Taycan (126.4 inches vs. 114.2 inches).

The BMW 7 Series may be more efficient, handle and accelerate better because it weighs up to about 550 pounds less than the Porsche Taycan.

For excellent aerodynamics, the 7 Series has standard flush composite headlights. The Taycan has recessed headlights that spoil its aerodynamic shape and create extra drag.

To make loading groceries and cargo easier when your hands are full, the 7 Series’ trunk can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Taycan doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

The 7 Series’ standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. An easy entry system costs extra on the Taycan.

Optional air conditioned front and rear seats keep the 7 Series’ passengers comfortable and take the sting out of hot leather in summer. The Taycan doesn’t offer air-conditioned seats in the rear.

The 7 Series has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the Taycan.

Both the 7 Series and the Taycan offer optional massaging front seats. The 7 Series also offers optional massaging rear seats in order to maximize comfort and eliminate fatigue on long trips. Massaging rear seats aren’t available in the Taycan.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW 7 Series has a standard wireless phone charging system (Qi) in the center console. The Taycan doesn’t offer wireless personal charging.

The 7 Series’ Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Optional Remote Control Parking will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Taycan doesn’t offer an automated parking system.
