The MINI Cooper Hardtop 2 Door 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 370Z doesn’t offer knee airbags.
The Cooper Hardtop 2 Door has standard Automatic Emergency Braking, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The 370Z doesn't offer collision warning or crash mitigation brakes.
The Cooper Hardtop 2 Door 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 370Z 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 Cooper Hardtop 2 Door’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The 370Z doesn’t offer a lane departure warning system.
The Cooper Hardtop 2 Door’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The 370Z doesn’t offer a driver alert monitor.
Compared to metal, the Cooper Hardtop 2 Door’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Nissan 370Z has a metal gas tank.
The Cooper Hardtop 2 Door has standard Assist eCall, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in or send emergency personnel to the scene if any airbags deploy. The 370Z doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Cooper Hardtop 2 Door and the 370Z have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, its standard front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Cooper Hardtop 2 Door the rating of “Top Pick” for 2018, a rating granted to only 170 vehicles tested by the IIHS. The 370Z has not been tested, yet.
