14: New Holes Throughout
When Ford sat down to do some modifications to the current Mustang, the company had to see how it could improve an already great design. The Bullitt has been a hit with consumers, as have the GT350 and GT500. The Mach 1 is not necessarily meant to be a full-on replacement, but instead another footnote in the long, storied history of the Mustang. The interesting design of the body already gave this generation a new look.
Ford has enhanced that design and added new holes to cram more air into the Mach-1. The brake calipers will get a lot more airflow, as will the newly improved V8. With these enhancements, the car is able to perform much better on the track. Save for a complete overhaul, the Mach-1 is a beast straight from the factory.
