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 Electrified G80 are reminded to check the back seat when a sensor determines the back seat is occupied. The S90 doesn’t offer a back seat reminder.
The Electrified G80 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 S90 doesn’t offer front seat center airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Electrified G80 has standard Parking Collision-Avoidance Assist-Reverse that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The S90 doesn’t offer backup collision prevention brakes.
Both the Electrified G80 and the S90 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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.
