Both the Charger and Leaf have child safety locks to prevent children from opening the rear doors. The Charger has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Leaf’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Charger has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Leaf doesn’t offer all-wheel drive.
Both the Charger and the Leaf have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The Dodge Charger weighs 447 to 1873 pounds more than the Nissan Leaf. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
