What is the steering ratio on a Ford Mustang?
In modern Mustangs, the steering ratio is not a fixed number; Ford uses a variable-ratio electric power-assisted steering (EPAS) rack that adjusts with speed and driving mode. The baseline is typically in the mid-teens, and the system can tighten for quicker response at low speeds and loosen for stability at higher speeds.
Understanding steering ratio in the Mustang
The steering ratio describes how far you turn the steering wheel to move the wheels. A lower ratio means quicker steering; a higher ratio means slower, more deliberate steering. Ford's current Mustangs employ EPAS with adjustable ratio to balance agility and stability across driving conditions. Because Ford updates tuning across model years and different trims, the exact figure can vary. The following provides a general guide to what you might expect in recent Mustangs.
Here is a concise look at typical baselines and how the system behaves in practice.
- Modern Mustangs (2015–present) use a variable-ratio EPAS rack with a base ratio in the mid-teens (roughly 15:1 to 16:1). The system tightens the steering feel at low speeds for quicker turns and relaxes it at higher speeds for greater stability.
- Special editions or performance packages may tune the ratio more aggressively to enhance precision and turn-in, depending on the trim and options chosen.
Despite these tendencies, exact numbers vary by model year and option. For buyers and drivers, the practical effect is a steering feel that changes with speed and drive mode rather than a single fixed ratio.
Historical context and what to expect by era
Older Ford Mustangs relied on hydraulic steering or early EPAS configurations with less adaptability. Modern versions prioritize a variable-ratio setup that can simulate a quicker response at low speeds and a steadier feel at highway speeds.
- Pre-2015 Mustangs: Most used hydraulic power steering or early electric assist, with less consistent tuning across speeds and modes.
- 2015–present: Introduced and refined variable-ratio EPAS, commonly described as mid-teens baseline with speed- and mode-dependent adjustments.
- Recent editions: Continued refinement for more precise steering feel, especially in performance-oriented trims and packages.
In short, there is no single fixed steering ratio for all Ford Mustangs; the system is designed to adapt. For precise figures, check the official specifications for your exact model year and trim.
Summary: The steering ratio on a Ford Mustang varies by year, trim, and driving mode, but modern Mustangs use a variable-ratio electric power-assisted steering system with a baseline in the mid-teens, designed to be quick at low speeds and stable at speed.
What is a normal steering ratio?
A steering ratio of x:y means that a turn of the steering wheel x degree(s) causes the wheel(s) to turn y degree(s). In most passenger cars, the ratio is between 12:1 and 20:1.
What is the steering rack ratio for a Mustang?
These Mustang kits are available in standard 20:1 Ratio and 15:1 Quick Ratio versions. These racks are ideal for road racing and other applications where a very responsive steering system is required.
What does 16:1 steering ratio mean?
Steer ratio is the relationship between steer rotation and wheels rotation. IE. 16:1 means that for every 16 degrees at the steer you will have 1 degree at the wheels (tyres)... thus 90degrees of steer will generate 5.6 degrees at the wheels.
What gear ratio does my Mustang have?
The majority of Mustangs come with a ratio of 2.73-3.31 from the factory. 3.73's are available from the factory depending on package options. If you have such an equipped Mustang and still feel that 3.73's are not enough, the next jump is up to 4.10's. However, 4.10:1 is a real steep gear.
