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, Chrysler and Mazda expand scope of Takata airbag recalls

The scope of the Takata airbag inflator recall is ballooning once again across the United States. Where Honda has elected to take its driver-side airbag campaign nationwide, Chrysler Group and Ford have now announced expanded regional actions to cover some passenger-side airbag inflators. Mazda is adding more regions, as well. For Chrysler Group, the campaign covers the inflators on 149,150 examples of the 2003-model-year Ram 1500, 2500 and 3500 pickups. The recall is limited to vehicles sold or ever registered in Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, Texas and the territories of American Samoa, Guam, Puerto Rico, Saipan, and the Virgin Islands. The company will begin notifying affected customers on January 19. According to Chrysler's announcement of the action, the passenger side inflators in these trucks "are of a type that is not used in any of the other vehicles affected by Chrysler Group's regional field action." The automaker says that it's not aware of any actual failures or accidents in these pickups and even claims there are no "observed failures in laboratory testing of its airbag modules." The company is continuing to study the problem, though. Ford is taking a similar step by issuing a recall of inflators for 38,500 examples of the 2004-2005 Ranger and 2005-2006 Ford GT. The campaign only affects vehicles originally sold or ever registered in Florida, Hawaii, Puerto Rico and the US Virgin Islands. Certain zip codes of Georgia, Alabama, Mississippi, Louisiana, Texas, Guam, Saipan and American Samoa are also covered. There's already precedent for passenger-side airbags to be covered under the Takata inflator recall. When many automakers announced campaigns in June, BMW, Chrysler, Ford, Honda, Mazda, Nissan and Toyota all included that side in some of their repairs. Subaru subsequently did, as well. In addition, Mazda is expanding the scope of its recall to add Florida, Puerto Rico, Hawaii, Saipan, Guam, American Samoa, US Virgin Islands, Georgia, Alabama, Louisiana, Mississippi and Texas to the affected areas. The company estimates that it has a total of 86,773 vehicles in need of repair. Mazda is also teaming with Toyota to begin independent testing of the Takata inflators.
