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 recalls 2020-21 Explorer and Lincoln Aviator, 2021 E-Series

Ford announced safety recalls for the 2020-2021 Explorer and Lincoln Aviator along with the 2021 E-Series early Monday. The recalls address entirely different issues.  In the case of the 2020-2021 Ford Explorer and Lincoln Aviator, that issue is motor mount hardware. Specifically, the fasteners that secure the passenger-side motor mount may back out. In Ford's words, this can result in a "loss of power," which is the entirely predictable result of an engine parting ways with the vehicle it powers.  As alarming as that may sound, owners should not have to worry about anything extreme, as the passenger side mount is only one of multiple, and Ford says it is not aware of any incidents that have occurred with vehicles in customer hands. Ford says it impacts only about 1400 examples of the Explorer and Aviator in the States (plus two in Mexico and 65 in Canada) that were built at Chicago Assembly Plant between July 28 and 30, 2020. Ford is in the process of alerting its owners to the recall, and those with affected models will have their mount hardware replaced by their local Ford dealerships free of charge.  The 2021 E-Series is being recalled for a potential heat management issue resulting from improperly aligned thermal insulation on the underside of its engine cover. In vehicles where this insulation was not properly installed so that it reaches all the way to the edges of the cover, the resulting heat bleed can cause high in-cabin surface temperatures, and direct contact them could result in burns.  This is the larger of the two recalls, as Ford says it covers nearly 33,000 examples sold in the United States and Canada. Fortunately, as with the above issue, Ford says it has not been made aware of any customer incidents. Ford says the remedy is a set of insulation patches for the exposed areas.  Related Video:
