It’s not the Ford Mustang’s fault that you crashed like a dummy

Why are Ford Mustangs always crashing? Dumb drivers with too much power, sure. But there's something different about the Mustang's suspension that gets a lot of blame. So what's the real truth here?

Until 2015, the Ford Mustang was the last passenger car in North America to still use a solid rear axle—like you find on pickup trucks—instead of independent rear suspension. Almost other sports car on the market had switched to IRS decades ago. Sounds like a problem that needed to be fixed.

It's true that a solid rear axle has some unique handling characteristics and reacts differently to road. When you're going around the corner at speed, the weight (and grip) transfers to the outside wheel. But because the rear wheels can't move independently, if you hit a curb or a bump with the inside wheel, those forces get transfered to the outside wheel. And if you're going fast and that outside wheel is already at the limit of grip, that disturbance can be all it takes to lose traction entirely and send a Mustang spinning into a crowd outside Cars & Coffee.

A solid rear axle also introduces a lot more unsprung weight and inertia, which means that the suspension is also slower to move up and down while reacting to those forces. It all adds up to make the Mustang more sensitive to rapid changes in grip.

But as with many things in life, once you understand why the car is reacting like it does, you can easily control it. All it really takes is a little adjustment with the steering wheel right as you hit that mid-corner bump to keep the Mustang on its line and out of trouble.

There are also upsides to a solid rear axle, which is why Ford kept it around as long as it did. It gives better grip when accelerating in a straight line and makes body roll less of a handling problem because the axle is always flat on the ground no matter how hard the car is leaning in a turn.

So the truth is, don't blame the Mustang's old school suspension for your insurance claims. Because in the end it's not the car—it's the driver.
