The Insurance Institute for Highway Safety, or IIHS, gave the Top Safety Pick rating to Toyota Prius Plug-In, whereas the National Highway Traffic Safety Administration, or NHTSA, gave five stars to Ford Focus Electric. The Tesla Model S, Ford Fusion Energy and Chevy Volt also received five-star ratings.
The independent, nonprofit organization IIHS determines safety ratings for vehicles to prevent motor vehicle accidents and reduce risks of injuries during crashes. The organization performs crash tests in cutting-edge facilities to assign appropriate vehicle ratings. The NHTSA is another organization that promotes highway safety and helps prevent car accidents.
While Toyota Prius Plug-In delivers poor performance, the IIHS considers it the safest electric vehicle as it is the only electric car among 2014 and 2015 models that received a Top Safety Pick. In the list of top electric cars with the highest NHTSA safety ratings as of 2014, Ford Focus Electric and Tesla Model S are the safest vehicles. Both models received full five-star safety ratings from the NHTSA. Tesla Model S scored perfect stars in frontal- and side-crash tests as well as in rollover tests.
Ford Fusion Energi received perfect five-star ratings in frontal- and side-crash tests and four-star ratings in rollover tests. In comparison, Chevy Volt scored perfect stars in side-crash and rollover tests and four stars in frontal-crash tests.
