15. 1969-70 Ford Mustang Mach I
Ford introduced the original Mach I as an affordable performance version of the Mustang Sportsroof in 1969. It featured a long list of options and three engines. The base was a 302 V8, but next came the 351 V8, and then the top-of-the-line model in the mighty 428 Cobra Jet. Although Ford built over 20,000 Mach Is in 1969, only a small number had the Cobra Jet engine, which was the definitive option to have.
Only 428 CJ-equipped Mach Is had true performance potential and could beat multiple other muscle cars on the street. They rated the 428 Cobra Jet at 335 HP, but most serious car followers knew it produced more than 400 HP. With a four-speed manual transmission and a skilled driver, the 428 Mach I could accelerate from 0 to 60 in just 5.5 seconds. For the time being, this was a fantastic number, so the 428 CJ Mach 1 still demands respect today.
