The 2013 Honda Accord is one of the 13 midsize sedans to receive the Top Safety Pick+ award.

Last month, the Insurance Institute for Highway Safety awarded 13 midsize sedans to its new Top Safety Pick+. In addition to receiving scores of "Good" or "Acceptable" in IIHS’s new small overlap frontal-impact crash test, the 13 vehicles chosen as Top Safety Pick+ winners received top scores of "Good" in moderate overlap frontal impact, side impact, rear impact and rollover crash tests.

The new small overlap frontal crash test, which was announced in August, simulates a front corner of a car crashing into something like a tree or utility pole traveling at about 40 mph. Vehicles are rated "Good", "Acceptable", "Marginal" or "Poor" in the new test. In December, the IIHS tested 18 midsize car models using the new scenario. An IIHS study conducted in 2009 found that the small overlap frontal impact crashes accounted for a quarter of serious or fatal accidents to front seat occupants.

The 13 midsize models that received the Top Safety Pick Plus are:

AutoWeek reports that only midsize sedans have been tested thus far, and IIHS plans to announce more Top Safety Pick Plus winners as they test more vehicles. By spring, the IIHS expects to have results for compact SUVs.

A total of 117 vehicles have been awarded Top Safety Picks for 2013, which means they got top scores in the original four crash test categories. For a full list of Top Safety Picks, click here.
