Although in recent years the IIHS Top Safety Pick list has included well over a hundred entries, the Top Safety Pick+ list looks like it will remain small for some time, and in the seven months since the first release of results some automakers—like Toyota, with its Camry ('poor' in the new test)—have been caught flat-footed.
The small-overlap improvements, while done under Honda's own engineering and research, were largely spearheaded by research published by the IIHS in 2009. Since then Honda has been following IIHS research in this area and working in parallel to understand how it can structurally improve its vehicles in this type of crash.
The ACE II improvements altogether add about 26 pounds to the body structure, and they apply to the entire family, including Hybrid and Si models.
The accolade now brings Honda's number of Top Safety Pick+ cars to five: the Accord Coupe, Accord Sedan, Civic Coupe, Civic Sedan, and Acura TL. At this point, all the Honda models that have been tested to the new standard have achieved the top rating, while a long list of models (the Honda Fit, Crosstour, CR-Z, CR-V, Insight, Pilot, Odyssey, and Ridgeline; and the Acura ILX, TSX, MDX, and RDX.
