NASCAR schedules tests for 2013 cars

Cup teams will have the 2013 model for an Aug. 7-8 test at Martinsville Speedway that is aimed at rules tweaks to make the cars lighter and help Goodyear develop tires with more grip to improve racing. The 2013 car also will be tested Oct. 4 at Talladega Superspeedway, Oct. 9-10 at Texas Motor Speedway and Oct. 18 at Kansas Speedway. Dodge is taking part in the tests. The manufacturer hasn't announced any replacements for Penske Racing, which will join Ford next year. USA Today
