For enhanced safety, the front and rear seat shoulder belts of the Porsche Macan have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Jeep Grand Cherokee doesn’t offer pretensioners for the rear seat belts.
The Porsche Macan 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 Grand Cherokee doesn’t offer a front passenger side knee airbag.
The Macan has standard Multi-collision Brake System, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Grand Cherokee 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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Macan. But it costs extra on the Grand Cherokee.
The Macan’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the Grand Cherokee.
The Macan offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Grand Cherokee only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the Macan and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes and blind spot warning systems.
