The electric 2022 Ford F-150 Lightning fully ditches the full-size pickup’s internal combustion engine, leaving in its place a frunk—you know, a front trunk. The amazing frunk is perhaps the most obvious visual result of the F-150’s electric transformation, but it’s only the tip of the iceberg when it comes to wholescale changes that Ford had to incorporate underneath the bodywork. A change in the F-150’s rear suspension was one of these monumental modifications necessitated by electrification.
That’s right—the new Ford F-150 Lightning is the first (and only) Ford F-150—and only full-size pickup, actually—with independent rear suspension (IRS) in place of traditional leaf springs and a live rear axle. Most manufacturers (including Nissan, Toyota, Chevy, GMC, and Ford) use time-tested leaf springs for suspending the rear of their solid-axle pickup trucks.
An exception would be Ram, which suspends its live axle with five links and coil springs on the 1500 pickup, a setup the upcoming 2021 Ford F150 Raptor will emulate. Oh, and of course, drop down a size class, and you’ll find the independently suspended (and unibody) Honda Ridgeline (go further down, and the new Hyundai Santa Cruz almost-pickup also sits on a fully independent suspension.)
