Safety

The Insurance Institute for Highway Safety crash-tested the 2008 Impreza, and the car earned a Good overall rating — the highest possible score — in frontal-offset, side-impact and rear crash tests (non-WRX seats). Those results apply to the 2009 model, too, according to IIHS.

Standard Impreza safety features include antilock brakes, side-impact airbags for the front seats, side curtain airbags, an electronic stability system and active head restraints for the front seats.
