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.

Mustang, Camaro, Challenger gallop onto USPS pony car postage stamp set

Some of America's most iconic cars are about to be immortalized on postage stamps. A new set by the U.S. Postal Service will celebrate the the golden era of pony cars, featuring five classic examples of Detroit iron. Each one is beautifully illustrated in oil-on-canvas style, with subjects in motion and sunlight glinting off the chrome, and would add a nice touch to any first-class letter. The pony car segment was all about (relatively) small, sporty alternatives to the full-size land yachts of the 1960s. They typically came equipped with 6-cylinder engines or small-block V8s. The category was named after the Ford Mustang, hence  the name. Some, though, argue that the Plymouth Barracuda, which was launched a couple of weeks before the Mustang, is the first. Luckily, the Falcon-based Mustang's distinct styling generated a sales sensation, or we might be calling them fish cars. Appropriately, one of the featured cars is a Mustang. But it's not just any Mustang. The 1969 Boss 302, seen here resplendent in Bright Yellow, was created for the hotly-contested SCCA Trans-Am racing series. One of its main rivals would have been the 1969 Chevy Camaro Z/28, also created specifically for the series, and is included in the set in Fathom Green. Representing Auburn Hills in the set is a 1970 Dodge Challenger R/T in Plum Crazy, while Southfield's American Motors gets a nod with an AMC Javelin in Big Bad Orange. The Mustang's platform cousin, a 1967 Mercury Cougar XR-7, is portrayed in a gorgeous Burgundy Poly that almost looks incomplete without Neko Case on the hood. It's not the first time the USPS has honored America's rich car culture on its stamps. In 2013, it issues a series of muscle car stamps with the help of Richard Petty. That set featured a 1966 Pontiac GTO, 1967 Shelby GT-500, 1970 Chevelle SS, 1970 Plymouth Hemi ’Cuda and, of course, a 1969 Dodge Charger Daytona. Another set in 2016 featured classic pickup trucks. Going further back, a 2008 release had chroed and finned automobiles of the 1950s and a 2005 release featured sporty American cars of the same era. The pony car stamps will debut on August 25 at the Great American Stamp Show in Sacramento, California in partnership with the American Philatelic Society. The public is free to attend the dedication ceremony, but you must RSVP first. After that, they will be available at local post offices and on line at the USPS store.

Automakers tussle over owners of 'orphan' makes

When General Motors put down several of its brands in recent years, it also let loose thousands of brand-loyal customers who will eventually need another car.
R.L. Polk Associates estimates there are more than 18 million cars from 16 discontinued makes on the road today. Those "orphan owners" have sales-hungry competitors seeing dollar signs. GM is offering Saturn owners $1,000 cash toward a Chevy Cruze, Cadillac CTS or a GMC Acadia. Ford is giving its Mercury lease customers a chance to get out of their contracts with no early-termination penalty and offering to waive six remaining payments if they drive off in a Ford or Lincoln.
Edmunds.com research shows the efforts are paying off somewhat for GM, with 39 percent of Pontiac owners, 37 percent of Hummer owners and 31 percent of Saturn owners taking delivery of another GM-branded vehicle. But that leaves as much as 69 percent of owners going elsewhere. Ford, Honda and Toyota seem to be attracting many former GM owners.
