Compare the2024 BMW 3 Series SedanVS 2024 Genesis G80

The BMW 3 Series Sedan has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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 G80 doesn’t offer a front passenger side knee airbag.

The 3 Series Sedan has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The G80 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.

Compared to metal, the 3 Series Sedan’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Genesis G80 has a metal gas tank.

Both the 3 Series Sedan and the G80 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, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
