Official USPS Muscle Cars stamps coming to a mailbox near you

As much as our digital lives have cut down on our trips to the post office, there are still times that sending "snail mail" is necessary. With us car lovers in mind and philately in their hearts, the good folks at the United States Postal Service will introduce a new stamp design called "Muscle Cars" starting on February 22.
Designed by artist Tom Fritz, the new collection of stamps consist of five classic muscle cars: 1969 Dodge Charger Daytona, 1970 Chevrolet Chevelle SS, 1967 Shelby GT-500, 1966 Pontiac GTO and 1970 Plymouth Hemi 'Cuda. In addition to just the stamps, the USPS is also commemorating the new series with plenty of collectable memorabilia. Previous car-related stamps include 50s Sporty Cars from 2005 and 50s Fins and Chrome from 2008.

2017 Ford Super Duty trucks recalled because the fuel tank could fall off

Bad news from Dearborn. Ford just announced a pair of recalls, including a particularly worrying flaw in the new F-Series Super Duty. According to Ford's official announcement, there are roughly 8,000 of its big trucks on the roads with a missing reinforcement bracket – if it's not there, the fuel tank could separate from the frame. Yes, Ford is basically saying the fuel tank could fall out. We don't need to explain why this would be a very bad thing. Fortunately, no owners have experienced said bad things – Ford claims it's unaware of any fires, injuries, or accidents resulting from the flaws. The Kentucky Truck Plant built the affected pickups between August 10 and September 17. The bulk of the vehicles are in the US – 7,103, to be precise. Another 964 are cruising around the frozen Canadian tundra, while two more are in "federalized territories." The other recall is smaller, but reaches across a broad swath of the Blue Oval's family vehicles. Ford says there are 1,352 Taurus sedans, Flex crossovers, Explorer SUVs – including the Police Interceptor Utility variant – and Lincoln MKTs equipped with the company's 3.5-liter EcoBoost V6 that could catch fire. In this case, the danger isn't a detached fuel tank, but an "improperly brazed turbocharger oil supply tube" that could leak and spill engine oil on the turbocharger. Again, Ford isn't aware of any fires, accidents, or injuries due to the flaw. Here's the breakdown of manufacturer dates and location: 2016 Ford Taurus vehicles built at Chicago Assembly Plant, Oct. 18, 2016 to Nov. 2, 2016 2016-17 Ford Flex vehicles built at Oakville Assembly Plant, Oct. 18, 2016 to Nov. 10, 2016 2017 Ford Explorer vehicles built at Chicago Assembly Plant, Oct. 15, 2016 to Nov. 12, 2016 2017 Ford Police Interceptor Utility vehicles built at Chicago Assembly Plant on Nov. 2, 2016 2016-17 Lincoln MKT vehicles built at Oakville Assembly Plant, Oct. 18, 2016 to Nov. 10, 2016 As with the Super Duty recall, most of the affected cars, crossovers, and SUVs are in the US market. There are 126 units in Canada and six in the same "federalized territories" mentioned above. In the case of both recalls, dealers will inspect the affected parts and replace or add them as necessary.

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.
