So what is SIPS? Side Impact Protection System
Volvo had side impact airbags over 20 years ago and has refined it to the point of almost perfection.
And what is WHIPS? Whiplash Protection System (what else were you thinking ;).
This feature is in my opinion the single best creation for safety systems in a 50 years. Broken bones heal but neck injuries are the worst type of injury by far. This system minimizes this a lot.
These are two of the biggest safety advances in cars and Volvo did it first.
