The Cadillac Optiq has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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 EX40 doesn’t offer a front passenger side knee airbag.
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 EX40 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 EX40.
Both the Optiq and the EX40 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear 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, rear cross-path warning and driver alert monitors.
The Cadillac Optiq weighs 513 to 739 pounds more than the Volvo EX40. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
