Project Ugly Horse: Part VII

Devils, Details and Weight Reduction
There are many things I could call this exercise. A party is not one of them.
I've spent three days crammed in the axle well of this 1989 Mustang with nothing to keep me company beyond a trouble light, a DeWalt drill on the very last of its legs and billion razor sharp, red hot slivers of metal with an affinity for my most sensitive of regions. My joints are raw from crawling around on the concrete. I'm half deaf from the shriek of the spot weld cutter and the boom of the cold chisel and hammer.

Ford made three big mistakes in calculating MPG for 2013 C-Max Hybrid

It's been a rough time for the official fuel economy figures for the Ford C-Max Hybrid. When the car was released in 2012, Ford made a huge deal about how it would beat the Toyota Prius V, which was rated at 42 combined miles per gallon, 44 city and 40 highway. The Ford? 47 mpg across the board. How did Ford come to this place, where its Prius-beater turned into an also-ran? Well, after hearing customer complaints and issuing a software update in mid-2013, then discovering a real problem with the numbers last fall and then making a big announcement last week that the fuel economy ratings of six different 2013 and 2014 model year vehicles would need to be lowered, the C-Max Hybrid has ended up at 40 combined, 42 city and 37 highway. In other words, the Prius trumps it, as daily drivers of those two vehicles have known for a long time. The changes will not only affect the window sticker, but also the effect that the C-Max Hybrid (and the five other Ford vehicles that had their fuel economy figures lowered last week) have on Ford's compliance with greenhouse gas and CAFE rules for model year 2013 and 2014. How did Ford come to this place, where its Prius-beater turned into an also-ran? There are two technical answers to that question, which we've got below, as well as some context for how Ford's mistakes will play out in the bigger world of green vehicles. Let's start with Ford's second error, which is easy to do since we documented it in detail last year (the first, needing to do a software update, was also covered). The basic gist is that Ford used the general label rule (completely legally) to test the Fusion Hybrid and use those numbers to figure out how efficient the C-Max Hybrid is. That turned out to be a mistake, since the two vehicles are different enough that their numbers were not comparable, despite having the same engine, transmission and test weight, as the rules require. You can read more details here. Ford's Said Deep admitted that the TRLHP issue is completely separate from the general label error from last year. Now let's move on to last week's announcement. What's interesting is that the new recalculation of the MPG numbers – downward, of course – was caused by a completely separate issue, something called the Total Road Load Horsepower (TRLHP). Ford's Said Deep admitted to AutoblogGreen that the TRLHP issue had nothing to do with the general label error from last year.

Ford lowers MPG ratings on six vehicles

Ford has announced that it will be lowering the fuel economy ratings on a number of its 2013 and 2014 model year vehicles after an error was discovered in the company's internal testing data. The EPA has been notified.
Worryingly for Ford, the vast majority of the vehicles affected are hybrids, including the C-Max, Fusion and MKZ in both hybrid and plug-in varieties (where applicable). Also covered as part of the rerating is the entire lineup of 2014 Fiesta engines, with the exception of the ST, including the turbocharged, three-cylinder EcoBoost.
The C-Max was originally rated at 47/47/47 mpg, but dropped to 43/45/40 last year and now to 40/42/37.
