The GranTurismo has standard Automated 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 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.
Over 200 people are killed each year when backed over by motor vehicles. The GranTurismo has standard Rear Emergency Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Challenger doesn’t offer backup collision prevention brakes.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the GranTurismo. But it costs extra on the Challenger.
The GranTurismo’s optional 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 Challenger doesn’t offer a lane departure warning system.
The GranTurismo offers an optional Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The Challenger only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The GranTurismo’s optional 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 GranTurismo 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, rearview cameras, available blind spot warning systems and rear cross-path warning.
