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.

Best 3rd row SUVs of 2022

If you plan on using a vehicle's third row a lot, let us at least make the suggestion that a minivan would be a smarter bet than anything you're going to see on this list of best three-row SUVs. Their third rows are bigger, more comfortable and easier to get to. The kids will definitely be happier. Here are our two top choices.  OK, now that that's out of the way, we totally get why minivans are totally depressing and that if the kids want to be happier, they can buy their own darn vehicle. You're buying, you're driving, you're being seen in it and you'd rather have a three-row SUV. Fair enough. Luckily, there are more choices than ever and they're really good. The best do a particularly good job of being family friendly without looking like a drab transportation appliance, although really, you can't go wrong with any of the mainstream three-row SUVs. Now, some of the luxury choices are a bit suspect, including those that are otherwise very appealing but have cramped third-row seats (the Genesis GV80 comes to mind). We're focusing on three-row SUVs here, so having a usable third row is a must.   In this list, we have broken things down into four sub-categories: Best Three-Row Crossover |  Best Full-size Three-Row SUV Best Luxury Three-Row SUV |  Best Flagship Luxury Three-Row SUV Note that we define crossovers as SUVs since most buyers use the terms interchangeably, but acknowledge that "crossover" is literally a vehicle with a car-like unibody structure as opposed to the truck-like, body-on-frame construction that traditionally has defined "SUV." In other words, we consider all crossovers SUVs, but not all SUVs are crossovers (specifically those in the full-size segment and some in the flagship luxury segment). Best Three-Row Crossover SUVs of 2024 2024 Honda Pilot Why it stands out: Exceptional storage and cargo space; unique second-row functionality; refined ride; versatile and capable TrailSport; advanced AWDCould be better: Subpar acceleration with lackadaisical transmission and engine response; so-so driver assistance tech Read our full 2024 Honda Pilot Review The Honda Pilot was completely redesigned for 2023. It maintains its predecessor's family friendly packaging and overall focus, but it has injected a welcome sense of style (especially in the TrailSport pictured above) that makes it stand out much better from the big crossover crowd.

Watch how Ford torture-tested the 2015 F-150

The Ford F-150 has been the best-selling truck in the United States for the past 37 years, and the best-selling vehicle outright for the past 32. That's quite a legacy, and thus, it's no surprise that Ford worked super-duper-extra hard on creating the all-new, aluminum-bodied 2015 F-150 that debuted at the Detroit Auto Show earlier this year.
During an event at the company's headquarters in Dearborn, MI this week, we were able to see all of the ways that Ford endurance tests, not just the new F-150, but all of its vehicles. From examining things like light exposure to interior materials and paint finishes, to making sure that corrosion absolutely does not happen when steel components come in contact with aluminum panels in the new truck. The goal: ensure that the new F-150 is nothing short of "Built Ford Tough."
But that's only a small part of the story. Of course, the new F-150 has to be able to withstand whatever a pickup buyer might throw at it - and truck buyers arguably demand the most from their vehicles. So in an effort to convey just what the new F-150 had to go through before being given the final go-ahead, Ford has released a series of videos, showing how its new halo truck was indeed torture tested.
