More and more speculation is surfacing about Ford releasing a new 2017-2018 Mach 1 Mustang instead of the GT500. Articles range from the Mach 1 having an upgraded 5.0L all the way up to a N/A 5.8L Trinity engine. The Mach 1 would most likely fit in between the GT and the GT350. Ford would be wise to make everyone wait another year for the next generation of GT500 as it would kill the gt350 sales. The Mach 1 is a Mustang legend and is ready to get back on the road. The video above has an upgraded 5.0L with a custom exhaust system.
