What is a Ford Explorer ST and How Does it Differ from the Base Model?
The “ST” in the name stands for Sport Technologies, a designation Ford reserves for vehicles that have undergone significant performance upgrades. While a standard Explorer is built for comfort and efficiency, the ST is built for speed and engagement.
The most immediate difference is under the hood. While base models often use a 2.3L four-cylinder engine, the ST comes standard with a 3.0L EcoBoost V6. This engine is paired with a 10-speed automatic transmission that has been calibrated for aggressive shifting and quicker response times.
Beyond the engine, the ST features a completely different aesthetic. You will notice blacked-out trim, a unique mesh grille, and larger wheels. Inside, the cabin receives bolstered leather seats with “ST” embroidery and a sport-style steering wheel, signaling that this is not your average grocery getter.
The Ford Performance Pedigree
Unlike some “sport appearance” packages offered by other manufacturers, the Explorer ST was developed by the same team responsible for the Shelby GT500 and the Ford GT. This means the chassis tuning and power delivery are designed to work in harmony.
The engineers focused on rear-wheel-drive architecture as the foundation. This setup provides a more balanced weight distribution, which is essential for a vehicle that weighs nearly 5,000 pounds but still needs to handle corners with precision.
The Heart of the Beast: 3.0L EcoBoost V6 Power
When people ask what is a ford explorer st, the conversation usually starts and ends with the engine. The 3.0L twin-turbocharged V6 produces a stout 400 horsepower and 415 lb-ft of torque.
This power is delivered through an Intelligent Four-Wheel Drive system. This system is biased toward the rear wheels under normal conditions to maintain a sporty feel, but it can shift power to the front wheels instantly if it detects traction loss or heavy acceleration.
For the DIY mechanic, this engine is a marvel of modern plumbing. It utilizes two small turbochargers rather than one large one. This design choice reduces “turbo lag,” ensuring that the torque is available almost immediately when you step on the gas pedal.
Transmission and Gearing
The 10-speed SelectShift automatic transmission is a key component of the ST’s performance. It features paddle shifters on the steering wheel, allowing you to take manual control during spirited drives through canyon roads or hilly terrain.
In “Sport Mode,” the transmission holds gears longer and downshifts more aggressively. This keeps the engine in the power band, ensuring you have maximum acceleration whenever you need to merge or pass slower traffic.
Suspension, Braking, and Handling Dynamics
Straight-line speed is only half of the story. To truly understand what is a ford explorer st, you have to look at how it handles the weight of a three-row SUV during high-speed maneuvers.
Ford Performance equipped the ST with stiffer springs and specialized dampers. These components reduce body roll, which is the tendency of a tall vehicle to lean over when turning. This makes the Explorer ST feel much smaller and more agile than its physical dimensions suggest.
The steering rack is also unique to the ST. It has a quicker ratio, meaning you don’t have to turn the wheel as far to get the vehicle to react. This provides a direct connection between the driver and the road surface.
The ST Street and High-Performance Packs
If you are looking at used models or ordering a new one, you might see mention of the “Street Pack” or the “High-Performance Pack.” These packages add 21-inch aluminum wheels and, more importantly, upgraded brakes.
The performance brake system features larger vented rotors and red-painted calipers. These are not just for show; they provide significantly more stopping power and resist “brake fade” during repeated hard stops or when towing a heavy trailer.
Daily Utility: Towing, Tech, and Interior Space
Despite its track-ready aspirations, the Ford Explorer ST remains a highly practical vehicle. It retains the three rows of seating found in the standard model, making it capable of carrying up to seven passengers depending on the seating configuration.
One of the most impressive specs is the towing capacity. When equipped with the Class IV Trailer Tow Package, the ST can tow up to 5,600 pounds. This makes it an ideal choice for off-roaders who need to haul a motorcycle trailer or a small camper to the trailhead.
Inside, the technology is centered around a 12.3-inch digital instrument cluster. This screen changes its layout based on the drive mode you select. For example, in “Track” or “Sport” mode, the tachometer becomes the most prominent feature.
Cargo Flexibility
The rear seats can be folded flat with the touch of a button in many trims. This opens up a massive cargo area for hauling gear, tools, or outdoor equipment. The ST proves that you don’t have to choose between a performance car and a utility vehicle.
For families, the inclusion of Ford Co-Pilot360 technology provides a safety net. This includes blind-spot monitoring, lane-keeping assist, and automatic emergency braking, ensuring that the high-performance drive is also a safe one.
Maintenance and Common Issues for the DIY Mechanic
As an expert automotive writer, I know that maintaining a high-output vehicle requires a bit more attention than a standard commuter car. If you own or are considering what is a ford explorer st, you need to be prepared for its specific service needs.
The twin-turbo engine generates significant heat. Using a high-quality full synthetic 5W-30 oil is non-negotiable. I recommend changing the oil every 5,000 miles rather than waiting for the car’s computer to tell you, especially if you drive it hard.
One common area to watch is the Power Transfer Unit (PTU). In many all-wheel-drive Fords, the PTU fluid can break down over time due to heat. Checking and replacing this fluid every 30,000 to 50,000 miles can prevent a very expensive drivetrain failure down the road.
Turbocharger Care
Turbochargers rely on oil for both lubrication and cooling. After a spirited drive, it is a good idea to let the engine idle for a minute or two before shutting it off. This allows oil to circulate and cool the turbo bearings, preventing “oil coking” or carbon buildup.
Always keep an eye on the coolant levels. The intercooler system on the 3.0L EcoBoost is essential for keeping intake temperatures down. If you notice a drop in power during hot weather, it could be a sign that the cooling system is struggling or has a minor leak.
Tuning and Performance Modifications
For many enthusiasts, the factory 400 horsepower is just a starting point. The Ford Explorer ST has a massive aftermarket following, allowing owners to unlock even more potential from the EcoBoost platform.
A simple ECU (Engine Control Unit) tune can often add 50 to 100 horsepower without changing any physical parts. Companies like Whipple and ZFG Racing offer calibrations that optimize boost pressure and ignition timing for higher octane fuels.
Upgrading the intercooler is another popular mod. The factory unit can heat-soak quickly during repeated pulls. A larger, high-efficiency intercooler keeps the air entering the engine dense and cool, which results in more consistent power delivery.
- Lowering Springs: Reduces the center of gravity for even better cornering.
- Exhaust Systems: Replaces the quiet factory mufflers with a more aggressive growl.
- Cold Air Intakes: Allows the turbos to breathe more freely and adds “turbo flutter” sounds.
Safety First: Operating a High-Performance SUV
Driving a vehicle with 400 horsepower requires respect. The Explorer ST is heavy, and while the brakes are excellent, physics still applies. Always ensure your tires are in top condition, as the all-season tires provided from the factory may struggle to find grip in extreme performance scenarios.
If you are performing your own maintenance, such as brake pad replacements or oil changes, always use high-quality jack stands. Never rely on a hydraulic jack alone when working under a 5,000-pound SUV. Safety is the foundation of any successful DIY project.
If you ever encounter a “Limp Mode” or a flashing check engine light, stop driving immediately. Turbocharged engines are sensitive to “knock” or “detonation,” and pushing the car through a mechanical issue can lead to catastrophic engine damage. When in doubt, consult a professional technician with experience in EcoBoost engines.
