By most standards and measures, the 2012 Acura RL is a very safe car. Yet at least one area of its crash-test results could be a cause for concern for the most safety-minded shoppers.
That said, its feature list is robust. Six airbags are standard, plus active front headrests, electronic stability control, and anti-lock brakes. Radar-based cruise control and automatic curve-following headlights are available, and a Collision Mitigation Braking System is bundled with adaptive cruise control (ACC), which adapts speed and distance to the vehicle in front. CMBS is bundled with adaptive cruise control (ACC), which adapts speed and distance to the vehicle in front.
The Insurance Institute for Highway Safety (IIHS) has tested and rated the RL in all of its categories, and while it gets top 'good' results in frontal, side, and rear tests, it didn't do well at all in the new roof-strength test. In fact, the RL has the worst results in the roof strength category of any model tested—indicating a higher-than-typical chance of injury in a rollover, which is, admittedly, less likely in a low sedan like the RL. A set of ratings from the federal government, in its recently revised tests, isn't available.
