The BMW i7 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The S90 doesn’t offer a front passenger side knee airbag.
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 Volvo S90 lacks camera washers, requiring you to manually clean the cameras for optimal performance.
Both the i7 and the S90 have standard driver and passenger frontal airbags, front side-impact airbags, driver 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 1007 to 1895 pounds more than the Volvo S90. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
