For enhanced safety, the front seat shoulder belts of the Volkswagen Jetta GLI are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The MINI John Cooper Works GP doesn’t offer height-adjustable seat belts.
The Jetta GLI has standard Autonomous 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 John Cooper Works GP doesn't offer collision warning or crash mitigation brakes.
Over 200 people are killed each year when backed over by motor vehicles. The Jetta GLI has a standard backup collision prevention system that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The John Cooper Works GP doesn’t offer backup collision prevention brakes.
The Jetta GLI’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The John Cooper Works GP doesn’t offer a lane departure warning system.
The Jetta GLI’s blind spot warning system 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. The John Cooper Works GP doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing out of a parking space safer, the Jetta GLI’s standard rear 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 John Cooper Works GP doesn’t offer a cross-path warning system.
Both the Jetta GLI and the John Cooper Works GP have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, post-collision automatic braking systems, daytime running lights and rearview cameras.
The Volkswagen Jetta GLI weighs 417 to 500 pounds more than the MINI John Cooper Works GP. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Jetta GLI the rating of “Top Pick” for 2017, a rating granted to only 212 vehicles tested by the IIHS. The John Cooper Works GP has not been tested, yet.
