Looks like this could happen sooner rather than later. It should at least have 350 HP from the 2.3 in the Focus RS but I'm hoping for closer to 400 HP. I've always been a fan of the Fox body SVO and below is my favorite. That Roush IMSO GTO was capable of 950 HP!

Been waiting for something like that since 2015.

Might make more sense in an aluminum body or the next iteration of the chassis.

Roush ran some of those turbo4s also, some were bodied as Merkur XR4Ti and some as Mustangs. I seem to recall Ron Fellows in a Mustang bodied one at Mosport in the late 80s - early 90s.

I saw one of the Merkur’s at the Rolex this year and really dug it! They had a V8 on display but the placard spoke of the turbo 4 and mentioned how stout they were but were more prone to failure and therefore less used because of the durability.

Seems kind of silly to have two four cylinder performance packages. Maybe the high performance package is testing the waters and if it goes well they'll replace it with an SVO?

Multiple markets?

TMS is spot on , as we have the GT 350 at one price point , and the PP2 at another. Granted geared to the performance crowd , but at different price points and technology upgrades. So we have a performance oriented Turbo 4 available , but upgraded to a lightweight sleeper for the boosted crowd and .....................Europe, Australia, Great Britain, etc. There are distinct tax breaks in some Countries , outside the US , when using smaller displacement motors, and there is definitely a different market in Europe , for instance. Bringing the SVO back and it the machine boasts a motor in the 375-400 range, there is no doubt the market for it would add to the provenance of the Mustang. I love the 5.0, and am not likely to have a 4 cylinder in my driveway , but I do know 3 close friends who would sell any vehicle in their driveaway today to be back in an SVO!!!

They should give it the GT350 suspension.
