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 2 Series are reminded to check the back seat. The GR86 doesn’t offer a back seat reminder.
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 GR86 doesn’t offer a front passenger side knee airbag.
The 2 Series 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 GR86 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.
The 2 Series offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The GR86 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 GR86 only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The 2 Series has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. Only the GR86 Premium/TRUENO offers a blind spot warning system.
To help make backing out of a parking space safer, the 2 Series has standard Cross Traffic Warning, helping the driver avoid collisions. Only the GR86 Premium/TRUENO offers Rear Cross Traffic Alert.
Both the 2 Series and the GR86 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, lane departure warning systems, rearview cameras and driver alert monitors.
The BMW 2 Series weighs 578 to 1060 pounds more than the Toyota GR86. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
