Although it’s only been a couple of years since the current Mustang was launched, Ford seems to be working on an update already. Our spy has sent us the first photos of a prototype Mustang being tested on the streets of Dearborn, Michigan. One would think that this being a mid-cycle update, visual changes would be minimal. However, the test car we see here has been disguised heavily.

Although the heavy camo makes it hard to gauge the extent of changes, the headlights and taillights appear to have been reworked with possibly new light graphics. The front fascia also seems to have gotten a onceover, with a reshaped grille being a possibility too. The lower part of the front bumper and the rear bumper also appears to have been redesigned.

However, underneath these subtle cosmetic tweaks, there will be some significant mechanical changes, the most important being the inclusion of the new 10-speed automatic gearbox that Ford has developed jointly with General Motors. This is great news for markets like ours where auto ‘boxes rule, as the ten-speed transmission, which has already debuted in the 2016 Chevrolet Camarao ZL1, has been widely hailed for being one of the quickest shifting.

The powertrain options are likely to remain mostly unchanged with the current V8, V6, and Ecoboost mills expected to carry over with subtle tweaks if any. Set to be launched sometime next year as a 2018 model, the updated Mustang will also spin off a Shelby GT500, which, according to the rumour mill, will have nearly 740 horsepower on tap from a new twin-turbo 5.0-litre V8. That’s sure to kick off a new horsepower war, especially with Dodge and its Hellcat models.

We’ll bring you more info and pics as they emerge closer to the car’s launch date.
