In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the i7 are reminded to check the back seat if they opened the rear door before starting out. The Taycan doesn’t offer a back seat reminder.
The i7 has standard Active Front Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Front Headrests system moves the headrests forward to prevent neck and spine injuries. The Taycan doesn’t offer a whiplash protection system.
The BMW i7’s optional Surround View offers available integrated front and rear camera washers, ensuring clear, all-weather visibility without the need for manual cleaning. In contrast, the Porsche Taycan lacks camera washers, requiring you to manually clean the cameras for optimal performance.
Both the i7 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, 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 BMW i7 weighs 443 to 1561 pounds more than the Porsche Taycan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
