When you think of autocross, lightweight sports cars and nimble hatchbacks typically come to mind. The idea of a full-size SUV tearing through cones in a parking lot might seem far-fetched, but the Ford Explorer ST challenges that perception. With a twin-turbocharged V6 engine, all-wheel drive, and a surprisingly well-balanced chassis, the Explorer ST is more than just a family hauler—it has the potential to be an autocross contender.
This article will explore what makes the Explorer ST suitable for autocross, the modifications needed to enhance its performance, and how it stacks up against more traditional autocross competitors.
The Ford Explorer ST: A Performance SUV Built for More
The Explorer ST is a high-performance variant of Ford’s long-running SUV. Equipped with a 3.0L EcoBoost twin-turbo V6, it produces 400 horsepower and 415 lb-ft of torque, giving it the kind of power usually reserved for sports sedans. Coupled with a 10-speed automatic transmission and an advanced all-wheel-drive system, the Explorer ST offers excellent acceleration and stability.
Key Features That Make the Explorer ST Autocross-Worthy
- Powerful Engine – The 3.0L twin-turbocharged V6 provides plenty of horsepower and torque, allowing the Explorer ST to rocket off the starting line.
- All-Wheel Drive (AWD) – Unlike rear-wheel-drive vehicles, the AWD system gives the Explorer ST added grip, which can be a major advantage on tighter courses.
- Sport-Tuned Suspension – While it still has SUV proportions, the Explorer ST’s suspension is stiffer than standard models, offering better handling in spirited driving.
- Selectable Drive Modes – The Sport mode optimizes the transmission and throttle response for better on-course performance.
While these stock features make the Explorer ST autocross-capable, the weight and size of the vehicle present challenges. However, with the right setup, drivers can mitigate these issues and turn the Explorer ST into an unexpected force on the autocross course.
Preparing the Explorer ST for Autocross
If you’re serious about bringing the Explorer ST into the world of autocross, some modifications can make a big difference in its performance.
1. Tires and Wheels: The Most Important Upgrade
Tires are the single biggest factor in autocross performance. The stock all-season tires on the Explorer ST are not optimized for aggressive cornering, so upgrading to high-performance summer tires is essential.
Recommended Options:
- Michelin Pilot Sport 4S
- Bridgestone Potenza RE-71RS
- Falken Azenis RT660
These tires provide superior grip and reduce understeer, allowing the SUV to navigate corners more effectively.
2. Suspension Upgrades for Better Handling
Lowering the Explorer ST can reduce body roll and improve stability in tight turns. Consider these modifications:
- Lowering Springs – H&R or Eibach lowering springs can lower the center of gravity.
- Upgraded Sway Bars – A stiffer rear sway bar helps reduce understeer.
- Performance Shocks – Replacing the stock shocks with sportier options improves response.
3. Brake Upgrades for Improved Stopping Power
Autocross courses demand strong, consistent braking. While the Explorer ST comes with sizable brakes, upgrading them ensures better performance.
- High-Performance Brake Pads – Hawk or EBC Yellowstuff pads offer improved bite.
- Stainless Steel Brake Lines – Provide a firmer brake pedal feel.
- Brake Cooling Ducts – Help prevent fade during repeated braking.
4. Weight Reduction: Trimming the Fat
At nearly 4,700 lbs, the Explorer ST isn’t light. Shedding weight improves agility.
- Remove unnecessary cargo and spare tire before an event.
- Swap heavy stock seats for lighter racing seats (if allowed in your autocross class).
- Consider lightweight aftermarket wheels to reduce rotational mass.
Driving the Explorer ST in Autocross
Bringing a large SUV to an autocross course requires a different approach compared to driving a small coupe or sedan. Here are some key techniques to maximize performance:
1. Managing Understeer
The Explorer ST naturally tends to understeer due to its size and weight. To counter this:
- Use left-foot braking to help rotate the car.
- Avoid excessive speed into corners to maintain control.
- Trail braking can help shift weight to the front tires for better turn-in.
2. Using AWD to Your Advantage
Unlike rear-wheel-drive cars that may struggle for traction, the AWD system allows you to get back on the throttle earlier when exiting corners. However, be mindful not to overpower the tires, as excessive wheelspin can still lead to a loss of grip.
3. Maximizing the 10-Speed Transmission
The 10-speed auto shifts quickly, but manual mode allows for better control. Use the paddle shifters to keep the engine in the optimal powerband between 3,500-5,500 RPM.
4. Walking the Course and Planning Ahead
Given the size of the Explorer ST, being precise with your driving line is crucial. Walk the course before each event to identify the best braking zones and apex points.
How Does the Explorer ST Compare to Traditional Autocross Cars?
The Explorer ST is unlikely to match the agility of Miatas, WRXs, or Corvettes in a tight autocross setting. However, it has unique strengths:
- Acceleration – Few cars in the autocross scene will out-accelerate a tuned Explorer ST.
- Grip – The AWD system helps maintain traction on loose or uneven surfaces.
- Comfort and Versatility – Unlike dedicated race cars, you can still drive the ST home in comfort with the family.
Real-World Autocross Experiences with the Explorer ST
Several Explorer ST owners have tested their SUVs in autocross events, with surprising results.
Owner Experience #1: John M. – San Diego Region SCCA John brought his mildly modified Explorer ST to an SCCA event and found that it handled better than expected. “The weight is noticeable, but with good tires and some brake upgrades, it holds its own. I was able to outrun some stock Mustangs.”
Owner Experience #2: Lisa T. – Houston AutoX Club Lisa’s Explorer ST featured H&R lowering springs and a tune. “I was skeptical at first, but the ST is fun! It’s obviously not as nimble as my old BRZ, but it’s a blast, especially when you surprise people with how quick it is off the line.”
Final Verdict: Is the Explorer ST a Viable Autocross Vehicle?
With the right setup, it can hold its own against traditional performance cars, providing plenty of fun for enthusiasts looking for an unconventional autocross experience.
While it may never be the dominant force in autocross, the Ford Explorer ST is a surprisingly capable competitor.
Whether you’re taking your first step into autocross or looking to challenge expectations, the Explorer ST proves that even a family SUV can get in on the action. So, if you’re an Explorer ST owner, don’t hesitate—get out there and push your SUV to its limits!
