For enhanced safety, the front and rear seat shoulder belts of the Jaguar E-Pace have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Cadillac XT4 doesn’t offer pretensioners for its rear seat belts.
Both the E-Pace and XT4 have child safety locks to prevent children from opening the rear doors. The E-Pace 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 XT4’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.
Using vehicle speed sensors and seat sensors, smart airbags in the E-Pace deploy with different levels of force to help better protect passengers of all sizes in different collisions. The E-Pace’s side airbags will shut off if a child is leaning against the door. The XT4’s side airbags don’t have smart features and will always deploy full force.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the E-Pace. But it costs extra on the XT4.
The E-Pace’s standard 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. A lane departure warning system costs extra on the XT4.
The E-Pace’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 XT4 doesn’t offer a driver alert monitor.
Both the E-Pace and the XT4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
