FORD revises MPG for 6 cars

Wow. The MKZ hybrid is at 84.4% and the Fusion hybrid is 89.3% of original.

I think that's fairly substantial.

 

Honestly its about time. They should have never posted those unrealistic numbers but, it did give them the claim that they beat Prius v for a while.

Wow, I just looked at it and those numbers were wayyyyyyy off. Unbelievable.

 

The Ford statement has this to say about the source of the error:

If I am parsing correctly, Ford is saying that they modeled the car air resistance incorrectly. That may be one source of error, but it is surely not the only one based on a review of the revised ratings that show different corrections for the same cars but different motors, and as much error in city testing as highway in some cases.

 

When they went from 47 to 43 I claimed it was only the first reduction. I was right.

Why not the C-Max? | Page 3 | PriusChat

Can anyone tell are they finally using all 5 EPA tests or still using the loop hole of using 2 tests and approximating the other 3?

 

Ford Reduces MPG Figures On C-Max Energi, Fusion Energi
c-max is now 42 / 37 / 40 down from 45 / 40 / 43
usion is now 44 / 41 / 42 down from 47 / 47 / 47

both fusion and c-max energi are now 38 mpg in hybrid mode 88 mpge in EV mode down from 43 mpg and 100 mpge.

beaten to it

 

It would be a hoot to dig up the old posts of Ford fanboys who 'explained' how Ford's superior technology bested Toyota.
AustinGreen was the loudest, as usual.

 

Well, he started another thread about it.

moderators kill this thread

I didn't see that one. Thanks

 

The thing I don't like is when fed/state governments then base regulations off this EPA MPG data. But they do.

Anyways: DC Incentives Alert-
Anyone living in Wash DC buying some of these vehicles you get sales tax exemption if car is > 40 MPG EPA CITY. be sure to take note of the changes to make sure you buy before the new MPG takes effect in the rules.

Also NJ/NY:
Watch your EZ Pass discounts based off >45 MPG EPA combined

 

Is there an alternative ?
Seems to me that Ford has to recompense buyers for the loss of savings.

 

Speaking of compensation,
Ford is offering a pittance.

I have not checked if the amount covers the extra cost in fuel, but compensation for increased emissions is in order, in addition to a nice penalty as incentive to be a little more careful in the future.

 

In my examples, nobody would lose their rebates, which are usually based on vehicle EPA MPG at time of sale.
But if someone had their eye on an effected vehicle for a future purchase, they may want to grab it before the reduced MPG disqualifies the incentive currently being given.

 

This is making PiP look even better. Ford's plugin model's gas mileage takes 2-4 MPG hit over regular hybrid models, thanks to trunk space robbing batery pack.

EPA needs to recalculate the well-to-wheel carbon footprint.

Toyota balanced PiP for both gas and electric efficiency very nicely.

 

Well, being honest makes the PIP look better. I wonder what the Ford numbers will be once they are forced to use the 5 test EPA calculations.

 

I don't see how Ford can avoid serious inquiries, and also suspect other manufacturers may possibly bring this to court.

 

Another thing is EV range was also reduced from 21 to 18 miles.

Of course the federal plugin tax credit amount will not change as it is not based on efficiency or ability to reduce emission. It is based to the size of the battery. Never mind the weight or space, the more you add, the higher incentive.

We are seeing Toyota made the right decision to make a plugin that they should instead of what they could. More EV miles does not mean better. A balanced design that gets the most out of both fuel is better, nevermind when or not the gas engine fires up.

There is a very good reason why it was designed that way. Look at the results and understand how they achieved it by not letting one fuel bias over another. The trick is to set up thresholds that would create synergy.

 

I probably would not have seen the other discussion but we've chatted about this before:
Tired of the CMax being compared to the v | Page 2 | PriusChat

From that earlier post, here are a set of coast-down, power curves:


The metrics used to calculate MPG come from data submitted to the EPA:

Test Car List Data Files | Cars and Light Trucks | US EPA​

The CSV file lists the engineering metrics for each vehicle.

Within the mass of data, there are two groups of three numbers predictive of the vehicle MPG:

• raw coast-down coefficients - these are accurate and predictive
• adjusted dynamometer coefficients - these were fudged, the source of the error

I'm glad to see Ford is doing the right thing, in effect a 'recall' of the sales driven MPG numbers. But I'm sorry that CR who publishes equally flawed numbers will blame the EPA when it was Ford who submitted the 'adjusted' dynamometer numbers. Regardless, we will get to see the impact on sales soon enough.

The CMAX had already been adjusted and we saw a dip in sales that was not matched by the Fusion. Now both have been revised and in the next 2-3 months, we should see effect relative to the Prius v and c models.
