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 Optiq are reminded to check the back seat if they opened the rear door before starting out. The Q4 e-tron doesn’t offer a back seat reminder.
The Cadillac Optiq has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Q4 e-tron doesn’t offer knee airbags.
The Optiq has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Q4 e-tron doesn’t offer front seat center airbags.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Optiq. But it costs extra on the Q4 e-tron.
The Cadillac Optiq’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Audi Q4 e-tron does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
The Optiq’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 Q4 e-tron doesn’t offer a driver alert monitor.
Both the Optiq and the Q4 e-tron have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, 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 and rear cross-path warning.
