The Ford Shelby GT500 is a popular name among vehicles undergoing revival like the Honda NSX and Ford GT. It was recently spied testing its supercharged 5.2-liter V8 engine. Mustang6G posted a video of the beast out on the roads and it is music to our ears! Now that we know what the Shelby variant sounds like, we can come to a conclusion about what’s under the hood as well.

Mistaken Mustang Rumors 

It has been said that allegedly every other GT500 mule we have seen to date on spy photos (since May) was actually refreshed GT350 mules mistaken for the big boy. We have all been wondering what engine the GT500 would get and it has been argued about back and forth between enthusiasts and industry professionals. This is an important question to ask, after all, since it will be the most powerful factory-built Mustang to come out of Ford’s factories in recent years. Anything above the monstrous Shelby GT500 normally would sport a Super Snake badge and made directly in Shelby’s shop.

Despite this GT500 prototype not displaying any of Mustang’s 2018 mid-cycle changes, it’s believed that the production models will come with a supercharged 5.2-liter V8. This beastly engine could potentially produce a whopping 700+ horsepower; however, it is not yet clear whether the motor will be a flat-plane crank or cross-plane crank.

Avoiding Power Roll-Over

Most recently, spy shots of the GT500 reveal that it will have a more aggressive front fascia, inspired by the current generation of ‘Stangs. The redesigned grille and larger air vents are obviously present to supplement the more powerful engine. The back of the car also sees some changes with an updated rear diffuser that pairs well with the car’s larger size and newly designed 20-inch wheels.


The interior of the new GT500 has not yet been seen, but we can expect it to be a slightly sportier version of the GT350. If you look closely at the spy photos, you will notice a visible roll cage in the back that leaves a lot to the imagination. Does this mean that the beast will be taken to the track to fully explore its newfound power?


Third Engine, The Charm?

So far we have heard that the GT500 will have either a twin-turbo 5.2-liter engine or a 7.0-liter V8. There has also been some speculation that it would feature a 5.2-liter flat-plane crank (FPC) V8 that would produce more power than the Challenger Hellcat (707hp). The engine would be paired with a quick-shifting dual-clutch transmission as standard equipment, while a manual transmission would be optional. From the video release (above), we can now infer that Ford could be shifting to a cross-plane crank (CPC) engine – just from the sounds on the clip. This also comes at a time when leaked information told us that the FPC supercharger was running out of power at around 7,500 RPMs.

The new Shelby GT500 is set to debut in 2018 as a 2019 model (still not confirmed). If that is in fact the case, it means that six years of hard work and R&D went into finding out how to effectively make the nameplate even bigger than it has even been before. No matter what rumors and true and which aren’t, we cannot wait for the release and confirmations.
