Safety features include active front head restraints, active head restraints, and eight airbags: dual front airbags, side-impact airbags for front and rear passengers, and head-protection curtains that run the length of the cabin on both sides. Active safety features start with anti-skid stability electronics and the latest evolution of ABS.For 2006, there is a slight change in E-Class nomenclature, thanks to a change in engine size. A new supercharged E55 AMG wagon also joins the lineup.
