The BMW 2 Series 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 Civic Si doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The 2 Series offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Civic Si doesn’t offer backup collision prevention brakes.
The M240i has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Civic Si doesn’t offer all-wheel drive.
The 2 Series offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Civic Si only offers a rear monitor.
To help make backing out of a parking space safer, the 2 Series’ standard cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Civic Si doesn’t offer a cross-path warning system.
Both the 2 Series and the Civic Si have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
The BMW 2 Series weighs 613 to 982 pounds more than the Honda Civic Si. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
