The 2013 Lexus IS sedans and IS C convertibles include a respectable list of safety features, although their crash-test scores aren't the best. That's likely due to improve next year, when the IS gets a complete redesign and bolstered body structure.
While neither the IS sedans nor the IS C convertibles have been rated in the latest federal crash tests, the sedans earned top 'good' ratings from the Insurance Institute for Highway Safety (IIHS) in frontal and side impact. But their scores for both the seat-based rear impact test and the roof strength test are just 'acceptable.'
Dynamic Radar Cruise Control feature, which can detect other vehicles ahead and maintains a set following distance, is paired with the Pre-Collision System.
