We've already been treated to an in-depth first look at the 2015 Ford Mustang, but here's a few pics of something that's yet to take the spotlight.
Spied testing on US roads, this camouflaged Mustang test mule sports a few features that set it apart from the V6, turbo four and V8 versions we've already seen.
Things like a prominent bonnet scoop, 295-section rear tyres and a quad-tipped rear exhaust. Vision-obscuring discs block our view of the brakes, but odds are good that there's uprated hardware there too.
As a top-tier performance model it's likely to have a V8 under than swollen bonnet, but whether it's a tweaked version of the standard 5.0 litre naturally-aspirated V8 or a turbo (or supercharged) variant has yet to be determined.
It's also unclear what name it will wear. Reports suggest Ford will drop the Shelby branding from future Mustang specials, and various rumours say names like Mustang Mach 1, GT350 or Cobra are all contenders for this flagship model.
Launch timing has yet to be confirmed, and it's not clear whether a hi-po Mustang will be making its way to Australia to join the four-cylinder and atmo eight-cylinder variants.
However expect to hear more following the Mustang's official sales debut in the USA later this year.
