The Ford Explorer ST has established itself as a benchmark in the performance-oriented three-row SUV segment. Since its introduction, the primary question for enthusiasts and potential owners has been the same: how fast can a 4,600-pound family hauler actually move? Testing data across multiple model years confirms that the Ford Explorer ST consistently delivers a 0-60 mph time between 5.1 and 5.3 seconds in optimal conditions, with some high-altitude runs extending into the 5.7 to 5.8-second range.

The Anatomy of the 5.1-Second Sprint

Achieving a 0-60 mph time that rivals entry-level sports cars requires a combination of brute force and sophisticated power management. The heart of this performance is Ford's 3.0-liter EcoBoost twin-turbocharged V6 engine. This powerplant generates 400 horsepower and 415 lb-ft of torque. Unlike naturally aspirated engines that need to climb high into the RPM range to find their strength, the ST’s twin turbos provide peak torque starting as low as 3,500 RPM.

In a standard 0-60 test, the Intelligent Four-Wheel Drive (AWD) system plays a crucial role. Upon launch, the vehicle experiences significant rear-end squat, transferring weight to the rear tires to maximize traction. The system can divert up to 100% of available torque to the rear wheels or distribute it across both axles in milliseconds to prevent wheel spin. This mechanical grip is what allows a vehicle of this size to break the 6-second barrier so convincingly.

Generational Performance: 2020 vs. 2025/2026 Models

While the core engine specifications have remained largely consistent since the ST badge was first applied to the Explorer in 2020, subtle refinements in transmission calibration and software have tweaked the driving experience.

The original 2020 Explorer ST was a revelation, clocking 5.2 seconds in initial major magazine tests. It utilized the CD6 platform, which was designed from the ground up to support rear-wheel-drive bias, a key factor in its athletic handling.

The 2025 mid-cycle refresh, which remains the current standard as of mid-2026, focused heavily on the interior and software, but performance remains at the forefront. The 10-speed SelectShift automatic transmission has undergone several software iterations to sharpen shift points in Sport Mode. Recent testing of the 2025/2026 models shows that the 10R80 transmission now executes downshifts with less hesitation, contributing to a more responsive "rolling start" (5-60 mph) performance, which typically sits around 5.8 seconds—a figure that accounts for the elimination of the initial launch boost.

Environmental Variables and Their Impact on Speed

0-60 mph numbers are never static; they are highly dependent on the environment. For the Ford Explorer ST, three main factors can alter your real-world results:

  1. Altitude: Turbocharged engines fare better than naturally aspirated ones at high altitudes, but they are not immune to thin air. In testing conducted at altitudes above 6,000 feet, the Explorer ST's 0-60 time has been recorded at 5.79 seconds. The turbos have to work harder and spin faster to generate the same level of boost, which slightly delays the power delivery.
  2. Tire Temperature and Compound: The ST typically comes equipped with high-performance all-season tires like the Pirelli Scorpion Zero. In temperatures below 40°F (4°C), these compounds harden, leading to increased wheel slip during a hard launch. Conversely, on a prepped drag strip or warm tarmac, the traction control intervention is minimal, allowing for the 5.1-second "hero runs."
  3. Fuel Octane: While the Explorer ST can run on 87 octane, Ford achieves its advertised 400 horsepower figures using 93 octane premium fuel. Using lower-grade fuel results in the engine management system retarding timing to prevent knock, which can add 0.2 to 0.3 seconds to your 0-60 time.

Transmission Logic: The 10-Speed Factor

The 10-speed automatic transmission is a polarizing piece of hardware, but in the context of acceleration, its closely spaced ratios are an asset. By having ten gears to choose from, the engine can stay in its "power band"—the specific RPM range where horsepower and torque are at their maximum—for nearly the entire duration of a 0-60 run.

In Sport Mode, the transmission behavior changes significantly. It holds gears longer and performs "rev-matched" downshifts. More importantly, it avoids the hunt for fuel-efficient gears. When you boot the throttle from a standstill, the ST executes rapid-fire shifts that keep the needle pinned near the redline, ensuring that the momentum is never interrupted.

Beyond 0-60: The Quarter Mile and Braking

While 0-60 is the most popular metric, the quarter-mile time provides a better picture of the ST’s high-speed stamina. The Ford Explorer ST generally crosses the 1,320-foot mark in 13.8 seconds at a trap speed of approximately 101 mph. This indicates that even after the initial burst to 60, the V6 continues to pull hard, making highway merging and overtaking effortless.

However, speed is only half of the performance equation. The ST features an upgraded braking system, particularly if equipped with the High-Performance Pack. This includes larger rotors and specialized brake pads. In independent testing, the ST has demonstrated a 60-0 mph stopping distance of 108 feet. For a vehicle that weighs over two tons, this is an exceptional figure, outperforming several compact sedans and crossovers.

Comparing the Competition

To understand the value of the Explorer ST's 5.2-second average, it is helpful to look at the broader landscape of performance SUVs available in 2026.

  • Dodge Durango SRT: The Durango SRT is the heavy hitter of the gasoline world, often clocking 0-60 in 4.1 to 4.4 seconds thanks to its massive 6.4L Hemi V8. However, it is significantly more expensive and suffers from much lower fuel efficiency (around 13-15 mpg compared to the ST's 20 mpg combined).
  • Kia EV9 GT-Line: As an electric alternative, the EV9 GT-Line offers a 0-60 time of roughly 4.5 seconds. While faster off the line due to instant electric torque, it lacks the mechanical engagement and top-end character that many ST buyers prefer. It also comes with the weight penalty of a large battery pack.
  • Ford Edge ST: The smaller sibling to the Explorer, the Edge ST, uses a 2.7L V6. Despite being lighter, its 0-60 time is usually around 5.7 to 5.9 seconds, making the Explorer ST the clear performance leader within the Ford SUV stable.

Modifying for More: The Ford Performance Tune

For owners who find 400 horsepower insufficient, Ford Performance offers an official calibration tool (tune) for the 3.0L EcoBoost. This is a popular modification because, when installed by a certified dealer, it typically maintains the factory powertrain warranty.

This tune optimizes the air-fuel ratio and increases boost pressure. Real-world results from the enthusiast community suggest that this official software upgrade can add approximately 30 to 50 horsepower and up to 50 lb-ft of torque. In terms of raw numbers, a tuned Explorer ST can shave nearly half a second off its 0-60 time, potentially hitting the 4.7 or 4.8-second mark. It also re-calibrates the transmission for even more aggressive shift logic, making the vehicle feel much more high-strung and responsive.

The Trade-offs of Speed

It is important to note that the Explorer ST's performance comes with specific characteristics that may not appeal to every family buyer. The sport-tuned suspension, which is necessary to keep the vehicle stable during a 5.2-second launch and through high-speed corners, results in a ride quality that is notably firmer than the Explorer Platinum or Limited trims.

On uneven pavement or city streets with frequent potholes, the ST can feel "busy," with more vertical movement transmitted into the cabin. Some reviewers have described it as "truck-like." Additionally, while the cabin was significantly upgraded in the 2025 refresh with a 13.2-inch touchscreen and better materials, it still retains the utilitarian roots of the Explorer platform. The focus here is clearly on the driving dynamics rather than pure luxury.

Handling and Lateral Gs

The ST isn't just a "stoplight drag racer." Ford engineers equipped it with stiffer springs, larger stabilizer bars, and specialized dampers. On a 300-foot skidpad, the ST can hold 0.86 g of lateral acceleration. While that might not sound impressive compared to a Mustang, for a high-profile SUV, it represents a high level of engineering. It means the vehicle remains composed during emergency maneuvers or spirited driving on winding back roads.

In the Motor Trend figure-eight test—a comprehensive evaluation of acceleration, braking, and cornering—the ST has recorded times around 26.0 seconds. This is a significant improvement over the standard Explorer models and proves that the AWD system and suspension work in harmony to manage the vehicle's mass.

Buying Advice: New vs. Used in 2026

As of April 2026, buyers have a choice between the refined 2025/2026 new models and the depreciated 2020-2023 models on the used market.

If the 0-60 time is your absolute priority, a used 2020-2022 model with a Ford Performance tune offers the best "speed-per-dollar" ratio. However, the 2025 refresh brought a much-needed interior overhaul, including the Google-based Ford Digital Experience infotainment and the availability of BlueCruise (Ford's hands-free highway driving system). For most families, the 0.1-second difference in acceleration is negligible compared to the massive leap in daily usability and interior quality found in the newer versions.
