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.

Recharge Wrap-up: Ford 1.0L EcoBoost a hit in Europe; Build a tiny inverter, win $1 million

In Europe, Ford's 1.0-liter EcoBoost engine is the best-selling turbocharged gasoline engine. The three-cylinder motor powers 20 percent of new Fords sold in Europe. Earlier this year, it won its third International Engine of the Year award, and between January and June, it was sold in about 120,000 cars. So far this year, 38 percent of Fords sold in the Netherlands, 35 percent in Denmark and 32 percent in Switzerland have been powered by the 1.0-liter EcoBoost. The engine's turbocharger spins at 248,000 rpm, and provides 24 psi of pressure. The engine produces up to 138 horsepower, depending on the version. Read more in the press release below. When lithium-ion battery packs are retired from the road, remanufacturing, repurposing, and recycling are worthwhile options, according to a study by Mineta Transportation Institute. The study included a cost-benefit analysis of those three options, and found remanufacturing to be the best route. To get the most out of them, batteries should be tested and have their damaged cells replaced then put back to use. Repurposing is the second best option, using the remaining available charge for something besides cars. Recycling on its own isn't profitable, but it could make economic sense with "increased technological breakthroughs." Learn more at Recycling International or download the report here. A smaller inverter for EVs can win you $1 million. The Little Box Challenge is an open competition to build a power inverter with a density of at least 50 watts per cubic inch. Google and the Institute of Electrical and Electronics Engineers (IEEE) are offering the hefty prize to the team that builds the inverter with the highest power density within an enclosed volume of 40 cubic inches. Teams must register by September 30. Read more at Green Car Congress or learn more at the Little Box Challenge website.

Driving the Ford Explorer ST and Volvo V60 Cross Country | Autoblog Podcast #613

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by West Coast Editor James Riswick. First they talk about driving the Volvo V60 Cross Country and Ford Explorer ST, with some thoughts about the Subaru Outback and Super Bowl commercials as well. Then they dive into the mailbag, answering questions and following up on the outcomes of previous "Spend My Money" segments. Finally they wrap things off with a new "Spend My Money," in which they help a listener pick a new car that will accommodate a new, tiny family member without sucking all the fun out of driving.
