2018 Shelby GT500 Mustang Test Mule

Video: 2018 Shelby GT500 Caught Testing


In recently captured spy video from Michigan, we get to see a heavily camouflaged S550 GT500 cruising the street. Originally reported on by Mustang6G.com, this latest spy video has the enthusiast community dying to know what Ford is cooking up!

Recent Spy Photos

Just last week, spy photos were captured of a camo’d up S550 rolling around that seems to be a 2018 Shelby GT500. With a completely covered front end and mismatched wheels, the test mule raised a lot of questions as many have theorized it could be a twin turbo S550 GT500.

Breaking Down The GT500 Test Mule

This test mule appears to be different than the one we saw last week. This S550 Mustang appears to S550 Shelby GT500 Mustang Prototypeborrow more of the GT350 R’s parts such as the rear wing and matching set of Carbon Fiber Wheels. However, it is kind of questionable that is uses a red trunk, which harshly contrasts the Avalanche Gray paint of the body.

Is It A Shelby GT350 Refresh?

Some people online have been quick to say that this is simply a 2018 Shelby GT350 refresh, based on the exterior styling. However, there are two things that lead me to believe this is a 2018 Shelby GT500.

First, it is not uncommon for auto manufacturers to use donor bodies to test out a new powertrain. So while it may look like a generic Mustang on the outside (or a GT350 in this case) there are very good chances that under the hood is a whole world of power, out of sight from spy photographer lenses.

Second, the exhaust note does not sound like a flat-plane crank engine, but rather a cross-plane crank engine. While the person driving the test mule doesn’t really get on it, you can still tell that it doesn’t have the same tone or pitch as the current production GT350 Mustangs.

Test Mule Roll Bar – Is It A Clue?

In the Mustang that was photographed last week as well as the one that was captured on video this 2018 Shelby GT500 Roll Barweek, both Mustangs feature a roll bar; it is unclear if it is a 4, 6 or 8 point system. While it is somewhat confusing why a test vehicle would have a roll bar setup, it is worth noting that the other pre-production Mustang we saw with a roll bar was the ’13 Shelby GT500.

Whether it is beefed up safety precautions or a tell tale clue of the mysterious new Mustang is yet to be seen.
