Unfortunately, the only EPA estimates we have access to are those estimates made available by the EPA for download, located here. Once the EPA makes the new estimates available in a format we can use, we'll update them here.
Or if there's some formula we can apply to the old numbers to get them closer to the new estimates we could to that too. The EPA has an estimate update calculator on the site that's independent from specific models, but we have no way of knowing how they're arriving at the new numbers.
This came up today in another thread, but I'll update here. It looks like we can calculate the new city and highway numbers with the math in the calculateMpg function. But I can't get from those new numbers to the new Combined estimate.
In the example from today, the new MPG estimates are 12 city, 16 highway, and 13 combined. I'm not sure how they get to 13 combined—it's not simply adding the two numbers and dividing by 2. And even the unrounded totals from calculateMpg don't give a combined value of 13. I can't find the method the EPA uses to calculate combined MPG anywhere. Frustrating.
