2015 Ford F-150 to get up to 26 miles per gallon

The 2015 Ford F-150 is one of the most important US vehicle debuts in years, be it in the pickup segment or the entire marketplace. While we've already known about the truck's engine lineup, its payload ratings and we've even learned a bit about how it drives, the truck's EPA-estimated fuel economy ratings have remained a mystery. The wait is finally over. Ford has announced numbers that put the latest F-150 as the mileage leader among gasoline-powered, full-size pickups in the US, with its new 2.7-liter EcoBoost V6 topping the charts. Starting with the entry-level naturally aspirated 3.5-liter V6, the rear-wheel-drive F-150 is rated at 18-miles-per-gallon city, 25-mpg highway and 20-mpg combined. Opting for four-wheel drive drops those numbers slightly to 17/23/19. If fuel economy is your absolute priority, then upgrading to the 2.7-liter EcoBoost V6 is the hot ticket. It improves things further to 19/26/22 in rear-wheel drive trim or 18/23/20 with four-wheel drive. The carryover naturally aspirated 5.0-liter V8 is rated at 15/22/18 as a 4X2 or 15/21/17 as a 4X4. Finally, the flagship 3.5-liter EcoBoost V6 tops the range in available torque and offers buyers 17/24/20 ratings with rear-wheel drive or 17/23/19 with four-wheel drive. "We are delivering with the toughest, smartest and most capable F-150 ever – and now the highest EPA-estimated fuel economy ratings of any full-size gas-powered pickup in America," said Raj Nair, Ford group vice president, Global Product Development, in the company's announcement. Depending on engine and drivetrain configuration, Ford contends that the 2.7-liter EcoBoost's top rating puts fuel economy up between 5 and 29 percent over the current generation, thanks in large part to the truck's lighter aluminum construction. Obviously, these are EPA estimates, and your mileage may vary – ours has. Recently, Autoblog team members have had real difficulty even approximating government mpg estimates on many EcoBoost models, including the new F-150. Scroll down to read Ford's full announcement, including comparisons to rival models.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

J Mays on the 2015 Ford Mustang

J Mays, head of design at Ford, may be retiring from the company after 16 years, but not before showing the world his swan song: the 2015 Mustang. Ford officially revealed its new coupe and convertible to the public at events around the world on Thursday, including a live unveiling on ABC's Good Morning America, and Mays was in attendance at the automaker's home event in Dearborn, MI, which is where we caught up with him for a few words about his new baby.
"It's a joy" to design the Mustang, Mays told Autoblog, adding that this sixth-generation coupe is his "favorite design so far." Of course, the 2015 model takes cues from all of the generations that came before it, but Mays said it was important to edit down the specific elements from previous models, leaving just enough off to let the customer "participate and fill in the blanks."
"If it doesn't sell itself, you probably aren't a Mustang fan."
