Ford trademarking 'Mach 1,' possibly for Mustang

A legendary name might be accompanying the redesigned, 2015 Mustang when it finally makes its world debut - Mach 1. Stumbled upon by the team at Ford Authority, the Mach 1 title was found in a trademark filing with the US Patent and Trademark Office, and would revive a name last used on the fourth-generation, 2003 Mustang.
While the the 2003 vintage was well and good, the Mach 1 is really remembered for a three-year run from 1969 to 1971 - it's best to just forget the emissions-choked 1972 to 1978 Mach 1s - when power output ranged from a modest 250 horsepower with the two-barrel, 351-cubic-inch Windsor V8 to "375 hp" (actual output was rumored to be well north of 400 horsepower) with the righteous, 429-cubic-inch Super Cobra Jet V8.
What does the title hold for the sixth-generation Mustang? It's tough to say. The fanatics at Ford Authority seem to think Mach 1 could take the place of the Shelby GT500 at the top of the Mustang hierarchy, which sounds like a valid argument. At the same time, we could see the SVT Cobra moniker returning for the flagship model, and the Mach 1 doing battle with the Chevrolet Camaro Z/28 (unless the Boss 302 were to return). Confounding things is the historical precedent - the Mach 1 was responsible for the death of the Mustang GT in 1969, so it might make sense as a volume performance model.

Which is more fuel efficient, driving with a pickup's tailgate up or down?

Thanks to the smoke wand in the wind tunnel, you can actually see the difference in our video.
Should you drive with your pickup truck's tailgate up or down? It's an age-old controversy that's divided drivers for decades. Traditionalists will swear you should leave the tailgate down. Makes sense, right? It would seem to let the air flow more cleanly over the body and through the bed. But there's also a school of thought that argues trucks are designed to look and operate in a specific manner, and modern design techniques can help channel the airflow properly. So don't mess with all of that: Leave the tailgate up.

Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.
