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.

What to see at the Detroit Auto Show 2023

The 2023 North American Auto Show — also known as the Detroit Auto Show — is underway downtown. If you want to attend the public days of the show taking place September 16-24, hereÂ’s what you need to know about attending. But now that Autoblog has done our reconnaissance during the showÂ’s press days, we can tell you about the actual cars (and other things) you can see and experience. WhatÂ’s new? Ford The big new item from Ford is the 2024 F-150 pickup. You can check out the new trick tailgate, and see what the fuss is all about. The 2024 F-150 Raptor also debuted at the show, if you like high-power, off-roady full-size pickups. The show will also be a good opportunity to see the Mustang Dark Horse and Mustang Mach-E Rally up close and personal. Unfortunately, we only saw the wild 2025 Mustang GTD at an offsite event during press days, but it's quite possible Ford will roll it out for the public. Cadillac Cadillac revealed its refreshed 2025 CT5 at the Detroit show, and you can get a look at the revised front and the new tech-focused interior. Cadillac recently unveiled the all-electric 2025 Escalade IQ, so you can stop and see the most powerful Escalade ever while youÂ’re there. It wasnÂ’t on the floor during media days, but Cadillac told us theyÂ’d bring it for the public part of the show. Jeep Jeep unveiled its 2024 Gladiator at the show, and you can check out the new interior and trim levels in person at the Jeep stand. Jeep also has an indoor track set up for ride-alongs. If you havenÂ’t had the chance to see the refreshed 2024 Wrangler yet, you can see that, too, along with examples from the rest of the Jeep lineup, along with its Stellantis sibling, Ram. GMC GMC showed off the new, larger 2024 Acadia SUV for the Detroit Auto Show. ItÂ’s bigger than before, but does more to differentiate itself from its Chevy cousin, the Traverse. GMC also has its Sierra EV on display if youÂ’re interested in catching that in person. What else to see A number of automakers have large displays at the show with many of their models represented. In addition to those who debuted something new at the show, Buick, Chevrolet (check out the Silverado, Blazer and Equinox EVs, as well as the Corvette E-Ray), Lincoln with the new Nautilus, Toyota (get a look at the new Tacoma), Volkswagen, Honda, Kia, Hyundai, Mini, Volkswagen, Honda, Chrysler (the Airflow concept is there), Fiat, Ram and Dodge (see the Charger Daytona SRT concept) all have a sizable presence.

Here are the best-selling cars and trucks from January 2015

Every month, Autoblog slogs through all the sales figures reported by automakers that do business in the United States, and, after a little bit of sorting, we put it into an easy-to-read chart in an attempt to make it as easy as possible to follow the ins and outs of sales and shipments. But that only covers the brands themselves, not the individual models they sell. And we think you'd all be interested in knowing which vehicles beat their rivals in sales from month to month, so we've put together this handy gallery to keep you in the know. While the leader of the pack may not come as much of a surprise, the order that the top ten finishes in changes frequently – due to automaker deals, the price of gas, etc. – and we've included some statistics to help you see how their current performance stacks up to month's past.
