The 2026 Ford Mustang RTR is a turbocharged performance variant featuring a limited-slip differential, Brembo brakes, custom suspension, and increased steering angle, designed for hooning rather than track racing. Despite weighing nearly as much as a Mustang GT, the RTR's rear-wheel-drive layout and EcoBoost engine make it more agile and rotation-friendly than its V8 counterpart, with an old-school handbrake enabling drift capability.
