EPA raw data

[Hersbird]

So I was poking around trying to decipher the EPA testing methodology and found these pages.
Download Fuel Economy Data
I downloaded the "2015 Fuel Economy Datafile" and found a great sort able resource. It probably has been mentioned here before but I haven't seen it so thought maybe it was worth mentioning.
I personally like the column N "Highway un-adjusted FE" which i believe is the old standard, completely un-adjusted, old school easy acceleration, easy braking, low speed highway test that best reflects the way hypermillers drive.
Here it shows a 10.3 mile test with a maximum speed of 60 mph and quite a bit of 40-60 mph fluctuation.
Detailed Test Information

So then sorting that column high to low and you see some good numbers, 3 almost 70 MPG hybrids, 2 more 65-67 hybrids, the TDI Golfs and Jettas, the BMW 328d turbo diesel, and the lowly Mirage CVT. Money wise it is the bargain economy champ. The un-adjusted old school city is 49.4 mpg, and highway 63.4 mpg. The Fiesta SFE is also pretty high and probably a much better car overall. Also contrary to the sticker they put on the window the manual version gets better then the auto in those old school tests, 41/61 mpg for the manual compared to 36/54 mpg for the auto.

They also list a lot of the other features and is a good way to compare lots of cars in one spot.

They had a writeup in the local paper last weekend that basically stated the 2025 requirement for around 55 MPG would be 40 on a modern car's window sticker.
They also reduced thieir results by 20% so maybe they do better than we think. Remember if you reduce any amount by 20% you have to increase the result by 25% in order to get to the same original amount.

The EPA should have never changed the way it calcluates MPG in 2008. Why should the EPA even care that most people are TERRIBLE drivers? Give the educated driver a better idea of what a car is capable of if driven sensibly.

CARS should come with FE-vs-MPH mappings just like AIRCRAFT come with 'flight envelope' graphs!

My intrepid was rated at 25hwy in 2000 and I could get 27-29 on a tank without any trouble. My '08 cts is rated at 26hwy and I have a tough time getting above 27-28 on a tank.
