The 2008 Acura RL is close to perfect in crash-test performance.
While this year's RL earned a solid five stars from the National Highway Traffic Safety Administration (NHTSA) in all crash tests as well as rollover resistance, it doesn’t get the Insurance Institute for Highway Safety (IIHS) rating of “Top Safety Pick,” due to poorly performing headrests.
Nonetheless, ConsumerGuide reports the RL has plenty of "worthwhile safety and convenience features" that include "side-impact and side curtain airbags and an electronic stability system"--all standard, according to Cars.com. ForbesAutos reports "child-friendly safety measures include 'anti-pinch' power windows" as well.
Among optional safety features is "an optional Collision Mitigation Braking System [that] uses a radar unit to measure distance to objects in front of the RL"; it "alerts the driver and, if necessary, applies brakes" when something is too close. ConsumerGuide also notes this system "tightens the front seatbelts if it determines a collision is unavoidable."
Cars.com reports "visibility is very good." ForbesAutos notes an optional "rear-view camera to help with parking" is available with the Technology Package.
