At the time, a spokesman for Chevy explained that in certain conditions the side curtain bags can deploy if the sensors determine that a rollover is imminent.
Deciding it’s better to be safe than sorry, the system will sometimes deploy certain airbags even though a rollover doesn’t eventuate.
Drifting, or creating a situation that has a certain combination of speed and vehicle angle, is one of those situations which can lead to an unwanted air bag deployment.
It’s now happened again, this time in a Cadillac CTS-V Sport Wagon.
Driving the vehicle at the time of the incident was GM employee Brad Doerr who was out to get some autocross action just prior to getting married. Speaking with Jalopnik, Doerr said he heard a loud bang and then one of the side curtain airbags deployed. Lateral forces are said to have reached around 0.92 g.
You can see Doerr driving the CTS-V Sport Wagon just prior to the airbag deployment in the video below.
