The 2009 Porsche Boxster isn't exactly a bestseller, so it's not been crash-tested by the major U.S. authorities. Safety features, however, are strong all around.
Cars.com states that "in addition to frontal airbags, the Boxster has side-impact torso airbags in the seat backrests, and head-protection airbags deploy upward from the doors." Edmunds reviewers are pleased to find that "standard safety features for the 2009 Porsche Boxster include antilock disc brakes" and "dual thorax/head side-impact airbags and roll-over safety bars." Of the standard safety features on the Porsche Boxster, Kelley Blue Book is most impressed with the Porsche Stability Management System, which they say is as "great for what it doesn't do—interfere with your fun during aggressive driving—as much as what it does—bail you out when the fun stops." Cars.com adds that "a tire pressure monitoring system and an electronic stability system are standard" on the Porsche 2009 Boxster, while the passenger seat offers "weight sensors that disable the front airbags when a child-safety seat is detected."
Driver visibility is a sore point in the 2009 Porsche Boxster. Edmunds mentions there is an optional "park assist" feature on the Porsche Boxster that aids in parking lot maneuvers. This is a big plus, as ConsumerGuide in particular is very critical of the fact that "top-up visibility is severely limited to the corners and aft."
