We already know quite a bit about the all-new 2015 Ford Mustang, and we’ll know even more in the coming weeks when Ford shows the new pony at the 2014 North American International Auto Show in Detroit. But the one piece of information we’re not privy to yet is the name of the range-topping (read: the fastest and most powerful) sixth-gen Stang to replace the fifth-gen Shelby GT500.

For a while, we’ve suspected that Ford will call the flagship sixth-gen Mustang the GT350, and now there is some solid evidence of this being the case. The blokes at Mustang 6G have uncovered what seems to be an internal Ford document outlining the new pony’s various body codes.

Present and accounted for are all the usual suspects, including V6 and V8 coupe and convertible models, but the file also lists a Shelby coupe and convertible. As such, it would seem plausible that the Shelby GT350 will be the name of the range-topping Mustang for the sixth-generation… at least until the track-focused Mach 1 makes an appearance.

The Motrolix Take

The decision to use the Shelby moniker on the flagship Mustang comes as a surprise to us, since we were under the impression that Ford would discontinue using the Shelby name on the top-end pony for this generation. However, it’s still very much possible that the document procured by Mustang 6G is in some way inaccurate, outdated, or otherwise incorrect. So before jumping to any conclusions, we’ll just wait until Ford makes its official announcement.
