It’s popped its mean mug up a bit too early, thanks to one eager Instagrammer. What you’re looking at is an early peek at the upcoming 2020 Ford Mustang Shelby GT500. The maddest of the Mustangs, outside of the not-street-legal Cobra Jet factory drag car. Actually, this one might be more insane because it most likely has essentially the same engine as the drag car but can dance in more directions.

Early speculation says to expect at least 720 horsepower, but some are saying that figure might be conservative. And that’s crazy. This may be the last hurrah for the horsepower wars, but it’s undoubtedly a targeted shot. 
That maw? It’s gaping. That wing? It’s large. Both are easily overlooked because the prospect hiding behind the exaggerated body bits is the most powerful street-legal production Ford Mustang ever built.
Like you, I assume, I’m very ready for the Adding Lightness Wars to commence. But I’m not in a total rush to see the Horsepower Wars fizzle out just yet.
