The Z has standard Automatic Emergency Braking with Pedestrian Detection, 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 Challenger offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.
The Z’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Challenger doesn’t offer a lane departure warning system.
The Z has standard Front and Rear Sonar System to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The Challenger doesn’t offer a front parking aid.
The Z has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Challenger’s blind spot costs extra.
To help make backing out of a parking space safer, the Z has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Dodge charges extra for Rear Cross Path Detection on the Challenger.
The Z’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Challenger doesn’t offer a driver alert monitor.
Both the Z and the Challenger have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
