State Farm has posted updated vehicle insurance ratings to show which vehicles are more or less expensive to insure than others.

The insurance company provides a cost index for each make and model for collision, comprehensive and liability insurance as well as for safety feature discounts.

Models that have, on average, lower claims costs for collision and comprehensive coverage generally are charged 10 percent to 40 percent less than the standard premiums for vehicles in their price range. Models that have higher-than-average claims costs for collision and comprehensive are generally charged 10 percent to 40 percent more than the standard premiums for coverage for vehicles in their price range.

Models that have lower-than-average claim costs for injuries to occupants qualify for up to 40 percent vehicle safety discounts. Premiums for liability coverage also vary according to claim histories.

The vehicle ratings are available on the State Farm website for most 2010, 2011, 2012 and 2013 makes and models. The ratings do not apply in Massachusetts, North Carolina and Canada. Approval of the ratings is pending in California.
