The Mazda 5 was redesigned for the 2012 model year, and as of yet, it hasn't been crash-tested by either the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS). Mazda says it's engineered the new van with a stronger body shell and with better roof strength to provide better occupant protection; we'll update this once official scores are in.
The Mazda 5 does have the usual safety equipment as standard, but it doesn't offer any of the advanced technology found on some of the competition. Three-row curtain airbags are included, as is a throttle-brake override system and stability control. Left off the features list: a rearview camera, blind-spot monitors, or even standard Bluetooth.
