This would require the DOE to buy a dynamometer and a rig for testing fuel economy, and to develop standards.

Our problem is we have vehicles built in Japan/Korea that are not sold in the US, vehicles from the US that are not sold in Japan, and vehicles from the ASEAN that not sold anywhere else.

So we have cars that only have Japan 10/15 ratings, cars that only have US EPA ratings, and cars that have not been officially rated by anybody, or which only carry the Indian economy ratings. These ratings are all based on completely different standards.

To rate these cars, the DOE will have to set up a testing center and will need to train drivers to perform economy tests set to very strict standards. Then you'd have to come up with a way to calculate economy loss due to wind resistance. In other words... we need a small wind tunnel or a place to do coast-down testing.

That'd be a full-time job, as there are sixty or so new cars and variants that come out every year in the Philippines, and over two hundred distinct variants of all cars on the road today.

Give me a dynamometer (has to be rolling road, can't be the Dynapack Speedlab uses), an operator and a clean room with a controlled environment, and I could probably test four cars a week, and have the official results by June of next year. But I'd need an operational budget in the millions to get it done. Just constructing the testing facility alone would probably require twenty or thirty million bucks.
