Ford recalls 83k Taurus and crossover models for halfshaft issue

Ford and the National Highway Traffic Safety Administration have issued a recall for some 83,250 vehicles in the US, for an issue with halfshafts. More specifically a "halfshaft retention circlip" might not have been properly installed on affected vehicles, with the result being halfshafts that may move improperly or disengage completely from the linkshaft while driving. The NHTSA release also notes that the issue may occur "without prior warning" which obviously factors in to the timeliness of getting this checked.
Should the halfshaft disengage, a few troubling things could happen. If it occurs while driving, power from the engine will no longer be transmitted to the wheels. And, if the vehicle is parked without the parking brake applied after disengagement of the circlip, vehicles may roll away even if they're transmissions have been placed in "Park."
Affected vehicles are as follows: Ford Edge and Lincoln MKX crossovers from model years 2012 to 2014; Ford Taurus and Lincoln MKS sedans from model years 2013 to 2014; Ford Flex and Lincoln MKT vehicles from model years 2013 to 2014.

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.

2020 Ford Explorer ST vs 2019 Dodge Durango SRT: How they compare on paper

For a few years now, the Dodge Durango SRT has been the sole three-row performance crossover from a non-luxury brand. That all changes now that the 2020 Ford Explorer ST is coming to market. Now we have two family crossovers with rear-drive-based platforms vying for buyers that demand practicality and power. As such, there's no better time to dig into their specs to see how they compare. We'll check out each crossover's horsepower, torque, space, capability and prices. The full specs are listed below, followed by some analysis afterward. We also compared the regular 2020 Explorer models to other crossovers in this segment, if if that's not enough, you can check out our car comparison tool. Performance The Explorer and Durango go about making power in very different ways. The Explorer goes the force-fed route with two turbos feeding a 3.0-liter V6, while the Durango's enormous 6.4-liter V8 produces power with air flow au natural. Of the two, the Durango has the greater output of 475 ponies and 470 pound-feet of torque, feeding the flames of everyone that lives by the phrase "There's no replacement for displacement." The Explorer is no slouch at 400 horsepower and 415 pound-feet of torque, though. Performance isn't purely based on power, though. Other factors play a role, such as weight, and in that regard, the Explorer is way ahead. At 4,701 pounds, it weighs a massive 809 pounds less than the portly Durango. This also means that both crossovers are very close in weight-to-power ratio, with the Explorer only slightly worse at 11.75 pounds per horsepower and the Durango at 11.6. Less weight will also play a roll in handling, and the Explorer is likely to feel sprightlier without so much mass to shift back and forth. Semi-related to handling are tire sizes. The Durango features 295-mm wide tires on 20-inch wheels. The Explorer has 255-mm wide tires on 20-inch wheels, but 21-inch wheels with 275-mm tires are available. So the Durango is working with more contact patch, but as we mentioned, it's carrying a lot more weight. 2020 Ford Explorer ST View 20 Photos Interior Space and Practicality Although the Durango SRT is the largest on the outside in every dimension, it loses out to Explorer repeatedly inside. The Ford has more headroom, leg room and shoulder room in nearly every row except the third-row where headroom comes up a bit short.
