Back in May, we got spy photos of what’s believed to be a mule of the 2016 Ford F-150 Raptor testing in the Southwestern desert. The photos were taken from a distance, but the cab shape was clearly that of the 2015 model, indicating it’s the new-generation chassis. We now have photos of the same, or similar truck, testing a little closer to home in Michigan. This time, the spy shooter was able to get closer. Close enough to get a listen to the exhaust note, which according to our source, sounded a lot like Ford’s EcoBoost V-6. We’ve long felt the EcoBoost could make a compelling engine option for the Raptor, and with the discontinuation of the 6.2L V-8 in the 2015 F-150, makes for a logical replacement.

The nose clip and bed uses sheetmetal from the outgoing model, but the difference in width accentuates the fact that this is in fact the next-generation aluminum-bodied truck. Another detail noted by the spy shooter is that the shocks are a different color that the blue-and-chrome color of the current Raptor’s Fox Racing shocks, suggesting a possible change in shock vendors. However, they could also be unmarked next-generation Fox shocks undergoing testing. We can’t wait to see the next-generation Raptor, and it’s unknown when it’s going to be unveiled, but it could be as soon as this fall’s Los Angeles Auto Show, or more likely, the 2015 Detroit Auto Show.
