Mach Five protagonists build the Mach 6. The Mach 6's engine is not designed to run on gas, which is a crucial story point, even though gas is still used for it through most of the series. It has all the features of the Mach Five, but redesigned or changed in some form or another. For example, the rotary saws are kept, but they're turned into laser saws, and the blades can pivot so things that are over head can be cut.
