NHTSA closes rollaway investigation into 1.56M Ford SUVs

It's taken four years of study, but the National Highway Traffic Safety Administration has finally closed the books on its investigation into rollaway accusations surrounding 1.56-million Ford SUV models.
The probe, which centered on the 2002-2005 Ford Explorer, 2002-2005 Mercury Mountaineer and 2003-2005 Lincoln Aviator, ends without the federal agency calling for a recall. According to The Detroit News, the investigation was closed due to a "low number of complaints" - NHTSA documented 180 such complaints that resulted in 14 crashes and six minor injuries, but the number of incidents have been slowing. The suspected defect rate for the trucks' automatic transmissions was found to be 4.4 per 100,000 units, and the brake-shift interlock mechanism failure rate was judged to be even lower at 3.4 per 100k.

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 exec downplays idea of aluminum-intensive cars

Ford certainly made waves when it rolled out the all-new 2015 F-150 made primarily out of aluminum. But while trimming weight off its vehicles is a top priority for the Detroit automaker, we shouldn't expect the lightweight metal to be used as widely on passenger cars as it has been on its new pickup. Speaking at the Automotive News World Congress on Wednesday, top Ford exec Joe Hinrichs said that using aluminum in passenger cars isn't as beneficial as it is in trucks – primarily because the weight savings isn't as dramatic, or as deeply needed. Though improved fuel economy is certainly one advantage of aluminum construction in a truck like the F-150, low prices at the pump have prompted Ford to highlight another advantage, and that's capability: With less weight on its own, a lighter-weight truck can carry and tow more than a heavier one, because it all comes down to combined weight ratings. Ford is expected to make the new F-Series Super Duty largely out of aluminum for the same reasons, and we wouldn't be surprised to see the next Expedition use the material as well. But while certain components in Ford passenger cars will be made of aluminum, we shouldn't expect entire chassis and bodywork assemblies to use the material as extensively as on the F-150, or on more upscale passenger cars from the likes of Audi or Jaguar. Dearborn is, however, investing in other lightweight materials. It has a joint venture with Dow Chemical to put carbon fiber into mass production, much as BMW has with its i3. The Blue Oval will use a combination of carbon and aluminum on its 2017 GT supercar, and it has stripped weight by removing amenities from the 2016 Mustang GT350R, but apparently neither is a method Ford can practically apply to its volume models.
