( http://www.TFLcar.com ) Have you ever wondered how automakers check for air leaks in a new vehicle. If so, we're got the answer for you. Ford uses the same thermal camera imaging that home builders use to check the air integrity of new homes. The new tech process is interesting and unique in that Ford can even tell when a seal or gasket in a new car is missing or misaligned. Check out this TFLcar tech demo video as we watch how new cars are tested to make sure that they are quiet, air tight and built to spec.
