The Mustang GT4 is based upon the Shelby GT350 with the same brilliant 5.2 liter V-8.

However the GT4 is built to be a race car, there’s nothing street legal about it. Instead of modding a Shelby GT350 to be a race car, why not build a mustang specifically for racing?

That was the idea behind the new GT4 car. The car was developed by Ford Performance, Multimatc, and KohR Motorsports. The car is now being built in Canada by Multimatic. This car was created to compete against the GT4 models of Porsche, McLaren, and Chevrolet.

The major differences between the GT4 and the Shelby GT350 are aerodynamics and weight.

The upgrades to aerodynamics are obvious with the large rear wing and splitters. The body is completely covered in carbon fiber. Since the car isn’t built to be street legal, the cabin of the car includes only whats necessary to be FIA compliant – roll cage, MOTEC data system, Sparco racing seat, and a racing harness.


The Mustang GT4 car got its first win in the Continental Tire Sports Car Challenge GT class at Sebring 120 3/17/2017. KohR Motorsports drivers Jade Buford and Scott Maxwell combined for the checkered flag.

“The car ran flawlessly and the strategy was perfect, — It feels good to get the first win for the Ford Mustang GT4. We were so close at Daytona, and in my mind, Sebring is just as special. It was a good win for KohR and Ford Performance and NanoProMT and we earned it.”

Not long before Sebring the GT4 car debuted with a pole position at Daytona.

A Gutsy Performance at Watkins Glen

Dean Martin and Jack Roush Jr. battled through adversity to score another big win for the Mustang GT4. Jack Roush Jr. remained in second place for much of the race, and then the rain started. The team made a decision to pull the car in early, and put rain tires on. The decision looked to be promising until the track was littered with crashes. It took so long to clean up the track, that the rain had stopped once the race restarted. The car had to come right back into to swap tires again. By the time Dean Martin got on track the car was all the way back in 7th place. Dean battled for position on every turn, making his final pass on the last lap. There was light contact in the corner as he made his final pass, and the KohR Motorsports driver escaped with the victory.
