For enhanced safety, the front seat shoulder belts of the Hyundai Elantra N Line 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 Cooper Hardtop 4 Door doesn’t offer height-adjustable seat belts.
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 Elantra N Line are reminded to check the back seat if they opened the rear door before starting out. The Cooper Hardtop 4 Door doesn’t offer a back seat reminder.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Forward Collision-Avoidance Assist in the Elantra N Line as “Superior.” The Cooper Hardtop 4 Door scores only 4 points and is rated only “Advanced.”
The Elantra N Line’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 Cooper Hardtop 4 Door 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 Elantra N Line’s standard Rear Cross-Traffic Collision Warning uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. The Cooper Hardtop 4 Door doesn’t offer a rear cross-path warning system.
Both the Elantra N Line and the Cooper Hardtop 4 Door 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, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.
The Hyundai Elantra N Line (Built after October 2024) has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Cooper Hardtop 4 Door has not yet been fully evaluated by the IIHS for 2025.
