CX-7's rigid unibody uses the Mazda Advanced Impact energy Distribution and Absorption System (MAIDAS) to realize high level of collision safety. This helps to protect occupants in various accident situations, including front, side and rear impacts. The body's frame sections are large in size and, as straight as possible, high-strength steel is used where it's effective, and subframe connections help absorb collision energy. Stamping the side frame from a tailored blank minimizes center pillar deformation during a side impact. 

The fuel tank is surrounded by substantial members to guard against leakage in a major rear collision. Six air bags (frontal and side for front occupants, side curtain for all outboard occupants) are standard. A special sensor anticipates a roll-over and inflates the side-curtain air bags early to guard against injury, maintaining inflation for approximately six seconds helping to keep limbs out of harm's way. Front occupant restraints have pretensioner and load-limiter mechanisms to maximize their effectiveness.

The Mazda CX-7 earned the highest government crash test rating -- Five Stars -- in frontal and side-impact crash tests conducted by the U.S. government’s National Highway Traffic Safety Administration (NHTSA). The 2007 Mazda CX-7 also earned a Four Star Rollover Star Rating from NHTSA for both the front-wheel drive and all-wheel drive models*
