My braincell fired again.EPA,Ann Arbor,Michigan,does the new car certification testing for all vehicles in the U.S. The carmakers,I believe,are supposed to provide the EPA with drag data so they can properly load the dynomometers they use in the testing.Perhaps you can GOOGLE the USGOV,and get a hold of the EPA folks for the numbers.Also,CAR and DRIVER Magazine has been the most comprehensive lay publication to provide such data.Check 'em out at the library.They also provide frontal area,and drag factors for selected models each month.They also have access to Chrysler Proving Grounds,East Chelsea,Michigan,and do comprehensive roadtests,including,drag-limited top speeds,something of great interest to tunnel-heads.
