Following the reveal of the 2021 Ford F-150, there are plenty of unanswered questions about the new truck. Some of these questions, such as the official pricing and output of the hybrid drivetrain, have leaked out. But the biggest mystery of all is what the next-generation F-150 Raptor will be like. Well, F150gen14 managed to film the first spy video of the next-gen Raptor undergoing testing.

The truck is still very much in the prototype phase, as evidenced by the heavy camouflaging and body cladding. This is still very clearly the 2022 F-150 Raptor, though - the wider fenders, aggressive wheels, and off-road tires are a dead giveaway. We even get a hint at what's under the hood.

The test driver does their best not to use wide-open throttle, but there are a few points in the video where we can start to hear the new Raptor's exhaust note. From what we can tell, whatever engine this truck uses sounds different than the current 3.5-liter twin-turbo EcoBoost V6 found in the current Raptor. It emits a lower growl that almost sounds like it could be a V8, like the first-generation Raptor. We might not know for sure until Ford officially announces the Raptor's powertrain, but it is still cool to see the next-generation model in action for the first time.

The next-generation Raptor will have some competition for the first time in the form of the Ram 1500 TRX. The TRX will use the same supercharged V8 found in the Hellcat models, meaning it could produce almost 700 horsepower. 450 hp in the current Raptor seems like plenty, but Ford better be ready to bring its A-game should the TRX turn out to be as powerful as we think it could be. The TRX reveal is scheduled for next week, but the Raptor reveal is still further away.
