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 reveals new rapid prototyping and low-volume production techniques [w/video]

It's called "F3T," and that stands for Ford Free-form Fabrication Technology. The process that The Blue Oval has developed means being able to sidestep the weeks-long process of tool-and-die making when engineers want to construct a new part, allowing them to fabricate a three-dimensional part from a two-dimensional sheet of metal in just hours.
While F3T is being developed it is limited to "low-volume prototyping or even low-volume niche vehicles," but the next step is to evaluate it for use in Ford's global manufacturing facilities. You can find out more about it in the video and the press release below.

Ford hybrids getting update to improve fuel economy

Ford has announced that it is introducing "calibration updates designed to improve on-road fuel economy for owners of the 2013 Ford C-Max Hybrid, 2013 Ford Fusion Hybrid and 2013 Lincoln MKZ Hybrid."
We can speculate that these changes are at least due in part to lawsuits over mileage claims of hybrid vehicles. The automaker is enhancing 2013 models starting in August by raising their electric cruising speed to 85 miles per hour from 62 mph, optimizing the use of active grille shutters and the climate control system, shortening the engine warm-up period by 50 percent and reducing electric fan speed to minimize the fan's energy consumption.
It bears mentioning that Ford is doing pretty well in the US electrified vehicle market this year. The company claims to have grown its share in the segment by 12 points to 16 percent while taking a high number of Toyota Prius trade-ins in the process. Conversely, Toyota has experienced a five-percent drop in new-Prius sales over the same period. Additionally, Ford states that it has increased its share of the US vehicle market by one percent this year, more than any full-line automaker.
