Ford Explorer ST-Line: Size, Specs, And Space Breakdown

Ford’s mid-size SUV lineup has always held a special place in the market, straddling the line between family hauler and performance machine. But when you slap the “ST-Line” badge on an Explorer, the conversation shifts. It’s no longer just about getting the kids to soccer practice; it’s about how much fun you have doing it. The ST-Line models—available in both the regular Explorer and the longer Expedition—bring distinct styling and, in many markets, tuned performance, but they often come with a trade-off: space. Performance-focused trims frequently shed the multi-configurable seating options of the base models in favor of sportier, fixed configurations. So, if you are eyeing an Explorer ST-Line, you need to know exactly what you are getting into regarding dimensions, power, and practicality.

Is The ST-Line Smaller Than The Standard Model?

The short answer is yes, but not in the way you might think. The exterior dimensions of the Ford Explorer ST-Line remain identical to other Explorer trims. You are still looking at a vehicle roughly 198 to 201 inches long, depending on the specific generation and whether it is equipped with the active grille shutters or certain front-end fascias. The wheelbase stays consistent, meaning the footprint in your driveway doesn’t change just because you bought the sportier version.

The real difference lies inside. The standard Exploration offers incredible flexibility with its Smart Slide second-row seats and a third row that can be easily folded flat and stored beneath the floor. The ST-Line, particularly the true “ST” performance version, often replaces this versatile setup with a more robust, sport-oriented second row. In some iterations, the third row is removed entirely to lighten the vehicle and accommodate larger brake cooling systems or performance exhaust headers. Even when the third row is present, the sport seats are bulkier, eating into legroom slightly. You lose the "magic" seat layout for raw, driver-focused ergonomics. If seven-passenger capability is non-negotiable, verify the specific model year and trim level, as this varies by region.

Powertrain Specs: More Than Just Looks

While some markets use "ST-Line" as a purely aesthetic package, Ford’s dedicated ST models pack significant power. The standard Ford Explorer typically relies on a 2.3-liter turbocharged I-4, which is competent but not thrilling. Step up to the ST, and you are greeted with a twin-turbo 3.0-liter EcoBoost V6.

• Engine: 3.0L Twin-Turbocharged EcoBoost V6
• Horsepower: 400 hp
• Torque: 415 lb-ft
• Transmission: 10-speed automatic
• Drive Type: Rear-Wheel Drive (base) with optional 4WD

This powertrain transforms the driving experience. The twin-turbos provide a broad torque curve that makes highway passing effortless and low-speed acceleration surprisingly punchy for a vehicle of this weight. The 10-speed transmission is well-mapped for quick downshifts when you bury the pedal. Under the hood, you’ll also find larger intercoolers, unique exhaust note tuning, and sometimes upgraded cooling systems for the brakes and transmission. It’s a noticeable departure from the utilitarian nature of the base model.

Cargo Space And Practicality

Let’s address the elephant in the garage: cargo capacity. Because the ST-Line often features a dual-exit exhaust system and occasionally loses that clever under-floor stowage for the third row, you see a reduction in maximum cargo volume. With all seats up, you typically have around 18 to 25 cubic feet of space behind the third row, which is enough for a few grocery bags or backpacks but not much more.

Fold the third row, and you get a decent amount of space for strollers or luggage, usually hovering around 50 to 60 cubic feet. However, if you have a 5-passenger ST model (no third row), you gain significant rear cargo space, often exceeding 80 cubic feet. This makes the 5-passenger ST the ideal choice for couples or single adventurers who prioritize gear—bikes, kayaks, camping equipment—over seating. The flat loading floor is a bonus, allowing you to slide bulky items in without obstruction. Just remember that the lowered suspension on the ST model, while great for cornering, might require a slightly higher threshold to load heavy items compared to the ride-height-adjustable trims.

Towing Capabilities

Here is where the ST-Line presents a potential compromise for many buyers. The standard Ford Explorer, when properly equipped with the towing package, can tow up to 5,600 pounds. The Explorer ST, however, often sees this rating drop. In many model years, the tow rating is reduced to approximately 5,000 pounds, and in some specific configurations or older model years, it drops even lower to 4,500 pounds. This reduction is due to the heavier performance components, different cooling requirements, and the focus on dynamic handling rather than heavy hauling.

If you regularly tow a large travel trailer or a boat, the ST might not be the right tool. For smaller campers, jet skis, or utility trailers, it remains perfectly capable. Always check the specific door jamb sticker (the JL label) for the exact tow rating of the individual vehicle, as options like the Class IV towing package can influence these numbers.

FAQ

Does the Ford Explorer ST-Line have a third row?

It depends on the configuration. Most 7-passenger ST-Line models do have a third row, but it lacks the slide-and-fold mechanisms of lower trims. Some 5-passenger ST models omit the third row entirely to lower the center of gravity and save weight.

How much does the ST-Line weigh compared to the base model?

The ST is generally heavier due to the larger 3.0L V6 engine, performance cooling systems, larger brakes, and the rear-biased drivetrain. Expect it to be several hundred pounds heavier than the 2.3L EcoBoost base model.

Is the ST-Line suspension too stiff for daily driving?

The ST comes with a sport-tuned suspension that is firmer than the standard setup. While it offers excellent cornering stability and reduced body roll, you will feel more bumps and imperfections in the road. It is comfortable enough for daily commuting, but if you want a cloud-like ride, the base trim is preferable.

Does the ST-Line have more horsepower than the Platinum trim?

Yes. While the Platinum trim focuses on luxury features and comfort, the ST focuses on performance. The ST’s twin-turbo V6 (400 hp) significantly outperforms the standard 2.3L turbo I-4 found in many other trims, though it is important to check yearly specs as Ford sometimes updates engine offerings across all trims.
