For enhanced safety, the front and rear seat shoulder belts of the Dodge Charger have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The BMW M8 doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Dodge Charger Four-Door 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 BMW M8 doesn’t offer height-adjustable seat belts.
Both the Charger and M8 Gran Coupe 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 M8’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.
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 Charger are reminded to check the back seat. The M8 doesn’t offer a back seat reminder.
