Ford has packed the current-generation Mustang full of the latest tech but while ten-speed transmissions, independent rear suspensions and flat-plane crank V8s are all well and good, the one thing that is still missing from the package is a full-fat GT500 variant. Well that is all about to change, and very soon too.

Thanks to an Instagram pic provided by sinister_lifestyle, we now know what the upcoming GT500 will look like when it is finally revealed at the 2019 Detroit Motor Show in January.

The pic was taken at a special dealer meeting and it looked much like the current range-topping GT350R but with a whole lot more aggression built in.

The rear wing is now bigger, no doubt necessary to keep the rear of the car in check seeing as it should be capable of reaching almost 200 mph when flat out. The front air intake has also grown to accommodate the extra cooling required for the supercharger. The wheels look to be a similar design to the GT350R but to our eyes those rear tires look a fair bit wider.

Earlier this year we got a glimpse of a leaked spec sheet for the GT500 which suggested that it would be fitted with a 5.2-liter supercharged V8 possibly without the cross-plane crank and making around 720 horsepower and 650 lb-ft of torque.

Our source suggests that this may be as high as 770 hp and 743 lb-ft. Either way, this Mustang will be the most powerful Ford ever put into production and should finally be able to match those pesky 600 hp+ Dodge Challengers and Chevy Camaros in a straight line not just on a race track.

Aside from a teaser video that claims that the GT500 will have over 700 hp and will be coming in 2019, no official announcements have been made, but whatever the details, this latest GT500 promises to be the biggest and baddest yet.
