Ford wants a new mileage standard

You can see from the test, how coasting can help. There are quite a few decelerations that can run engine off, the test is less than 10 minutes. Click high speed.
Detailed Test Information

Click highway also to see the mostly staying under 60 mph. The high speed test was supposed to take away some of the benefit of the underpowered civic hybrid and prius, from the pre-2008 tests. As you can see the c-max is not penalized nearly as much, allowing it to get a higher score. A simple fix would be to keep high speed, raise the speed of highway 20%, and change the weighting factors. This would also decrease SUV and truck highway mileage.

The changes in 2008 also added the cold test, which brought hybrids more in line. But this uses the city test, which is quite long, 31.2 minutes, with only short stops. The city test was designed to replicate LA city driving long ago, and this test should be modified for more current city driving.

 

Agreed. Lets be clear. The performance is great, it's the fuel economy that could be better. lol

 

I am not suggesting we pick an extreme, I am suggesting that the EPA test the car and not the driver.

E.g.,
Publishing tests at different speeds lets a consumer pick a car that is most efficient at the car speed that person drives;

Requiring that the test slam on the brakes 20 feet before each red light rather than coast up to the light and letting road friction slow the car down simply standardizes stupid driving, and I do not see why the car should be tested that way, even if the majority of US drivers drive like fools. Hybrids have regen braking. Should the car test reflect the regen ability, or ignore it because it requires gentle braking ?
