USPS releases hot rod stamps to speed up your delivery

After one of the worst winters in recent memory for much of the country, summer is finally here. It's time to drop the top, open the sunroof or at least put down the windows and take a long drive. The United States Postal Service is celebrating the season's sun in automotive style with two new hot rod Forever stamps.
Both stamps depict classic '32 Ford hot rods. One shows the car from the front at a low angle in red (pictured above), while the other depicts the car from the back in black with flames running down the side.
To introduce the new stamps on their first day of availability, the USPS went straight to the source at the National Street Rod Association Street Rod Nationals in York, PA. They were unveiled by Postmaster General Patrick Donahoe, Car Crazy host Barry Meguiar and NSRA Special Events Director Jerry Kennedy.

eBay Find of the Day: 25-station video gaming trailer w/ bonus Ford F-250

Why, you might be asking yourself, is Autoblog showing me an eBay Motors listing for a 2006 Ford F-250 and a box trailer (with a badly cropped photo to boot)? It's not because we're highly interested in this blue-collar rig, to be sure, but rather because we're interested in throwing the greatest Forza party of all time. Housed in that innocuous white 26-foot trailer is a gamer's delight, with 25 Xbox 360 systems connected up to 25 high-definition monitors and 24 headsets to keep everyone locked into the action (one of the stations is outside the trailer). When connected up to one of two included generators, the setup allows for two-dozen combatants to square off, back-to-back and head-to-head. Sure, the Buy It Now price of $79,000 seems steep considering the trailer will need about ten grand worth of Xbox One or Playstation 4 upgrades in the near future. But that doesn't mean you couldn't squeeze out a few more years of massive multiplayer fun. Check out the listing here, and do let us know if you buy it, we'd love to come over and game.

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.
