The 2011 Mercedes-Benz C-Class, tested under the NHTSA New Car Assessment Program for US-market vehicles, received an overall rating of four out of five stars. In frontal crash testing, it earned three stars. Side crash protection was rated at five stars, the highest level. Rollover resistance received four stars, and side pole crash testing also yielded four stars. NHTSA applies this rating across model years until a significant redesign occurs, so these results represent the performance of the C-Class during this generation.
