Every Mustang Engine Listed

The Most Powerful Mustang Engines Ranked

We took every Mustang engine ever fitted and ranked them from the most powerful Mustang to the least powerful Mustang. Where do they all stack up?

What is the Most Powerful Ford Mustang Engine

The 2020 Mustang Shelby GT500 has the most powerful Ford engine. This formidable supercharged engine generates 760 horsepower and 625 pound-feet of torque. That means the 2020 Mustang GT500 is the most powerful street-legal Ford in history. When we first started this blog, the 662 horsepower and 631 pound feet of torque 2013 GT500 was the most powerful Mustang Ford has ever built, and for a time, it was the most powerful production car engine ever built in North America. The aluminum block 5.8-liter V8 uses a massive, 2.3-liter supercharger that adds 14 psi of boost to get those numbers, yet it can still get 24 miles per gallon on the highway. Modern aerodynamics give the car a top speed of 189 miles per hour, and launch control helps it hit 60 miles per hour in 3.5 seconds. The 2020 GT500 is an altogether even wilder animal. As the most powerful and quickest factory Mustang ever, the Ford Mustang Shelby GT500 blends modern sports-car performance with iconic muscle-car presence. The 760-hp supercharged 5.2-liter V-8 revs to 7500 rpm and with a seven-speed dual-clutch automatic it is good for 3.5-second rip to 60 mph and an 11.0-second quarter-mile.

Mustang Engines Ranked from Most to Least Powerful

Not surprisingly the most powerful Mustang engines are all the supercharged monsters of the last few years. Midway down the top 50 lists is the 1968 Mustang with its 390 horsepower 427 FE Hipo V8 (7.0 L) and a few places behind that is the 429 Boss V8 (7.0 L) at 375 horsepower. We have a lot of nostalgia for the classic and powerful Mustang engines we remember from yesteryear, but when it comes to outright power it is impossible not to be wowed by the 700 hp streetable cars that come out of Ford in the 2020s.
