2015 Ford Mustang EcoBoost flogged and analyzed by Ignition

Aside from the way it looks and perhaps its independent rear suspension, the biggest bit of news on the 2015 Mustang may be the inclusion of its 2.3-liter, turbocharged four-cylinder engine. That blown mill marks the first time since the Mustang SVO of the '80s that a turbo has been fitted under the engine of Ford's pony car.
The Mustang EcoBoost is the subject of the latest episode of Ignition from Motor Trend, giving us a great look at the technical, nitty-gritty side of the turbocharged coupe. Covering it from bow to stern, host Carlos Lago walks us through the boosted Ford before taking to the track for some driving impressions, with particular praise given to the low-end grunt of the 2.3-liter mill.
Check out the full video and then let us know which 2015 Mustang has your interest piqued the most - the EcoBoost four, the 5.0L V8 or the entry-level V6.

Next Ford Raptor spotted wearing aluminum skin

Well, look at what we have here. Judging from these spy shots, Ford is indeed working on the next generation of its off-road-ready F-150 Raptor pickup truck. We've made no attempt to hide our appreciation for the Baja-style truck, which combines most of the usability of a fullsize truck with heavy-duty suspension components to make a kind of performance vehicle that is unique in the market.
What we haven't known, until now, is whether Ford would push forward with its Raptor program now that it has a completely new F-150 to serve as its base. And that's especially true since Ford made the bold move of switching the bodywork of its best-seller from tried-and-true steel to aluminum. As you can see above, the front and rear of this silver truck are clad in current-gen Raptor bodywork, while the center section that houses the occupants appears to come from the upcoming 2015 F-150.
Dissecting the views above, we note a few interesting tidbits. First, there looks to be a bulge in the truck's hood. Second, we see a new grille between the current Raptor's headlights, sporting a mesh finish and two horizontal bars. Lastly, our eyes can't help but lock in on those burly A-arm suspension pieces down below, not to mention all that ground clearance the specialty suspenders bring to the table.

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.
