The Ford Expedition Tremor is the first genuinely trail-capable version of the nameplate - a three-row SUV that can carry seven passengers and also engage Rock Crawl mode on a fire road in the Catskills. For Nassau County families who want capability beyond the school pickup line, here is a complete breakdown of what the Tremor is, what it adds over the standard Expedition, and what it costs to get there.
Bottom Line: The Expedition Tremor pairs the 440-HP High Output EcoBoost with an electronic locking differential, raised suspension, Rock Crawl mode, and Raptor-derived skid plates - making it the most capable Expedition ever built while remaining a comfortable seven-passenger family SUV.
- The 3.5L High Output EcoBoost produces 440 HP and 510 lb-ft of torque - the most powerful engine available in any Expedition
- Rock Crawl mode is exclusive to the Tremor and joins Normal, Sport, Tow/Haul, Eco, Slippery, and Off-Road modes
- Trail Control, Trail One-Pedal Drive, Trail Turn Assist, and an electronic locking rear differential are all standard
The High Output Engine: What 440 HP Means in a Full-Size SUV
The Tremor is the only Expedition that comes standard with the High Output engine. The 3.5L High Output EcoBoost V6 makes 440 HP and 510 lb-ft of torque versus the 400 HP / 480 lb-ft standard EcoBoost in every other Expedition trim. That 40-HP and 30 lb-ft advantage is meaningful when you are moving a loaded seven-passenger SUV off a highway ramp, merging onto the Long Island Expressway with a trailer behind it, or climbing a rutted forest service road.
The High Output engine does not change the Expedition’s character - it is still a smooth, quiet 3.5L V6 twin-turbocharged engine that most drivers will never push to its limits. What it does do is provide a reserve of power that makes the Tremor feel effortless in situations where a standard Expedition would feel adequate. For Long Island buyers who regularly tow a boat, a horse trailer, or a large utility trailer, the power increase is a real working advantage, not just a spec sheet number.
The Heavy-Duty Trailer Tow package is standard on the Tremor. This includes the wiring, hitch, and cooling upgrades that maximize towing capacity - an important distinction from the standard Expedition where the trailer tow equipment is an add-on.
Off-Road Hardware: What the Tremor Adds
Rock Crawl mode is the headline feature that separates the Tremor from every other Expedition. It is a dedicated drive mode - not just a setting adjustment - that configures throttle mapping, AWD torque distribution, and the electronic locking differential for slow-speed technical terrain. The locking rear differential mechanically forces equal wheel spin front-to-rear, which is exactly what you need when one tire lifts off the ground on a steep, uneven surface.
Here is what is physically different on the Tremor versus a standard Expedition:
- Raised suspension with premium passive shocks and revised spring rates that increase ground clearance for approaching obstacles
- Modified Raptor-derived skid plates protecting the front underbody, transmission, and fuel tank from rock strikes
- Trail Control - a low-speed cruise control that maintains a constant, slow vehicle speed over rough terrain so the driver can focus entirely on steering
- Trail One-Pedal Drive - modulates braking through accelerator position alone on technical terrain, eliminating the need to move between pedals
- Trail Turn Assist - applies brake pressure to the inside rear wheel at low speed to tighten the turning radius on tight trail switchbacks
These are not comfort features - they are engineering investments that make a large SUV genuinely functional on terrain it would otherwise struggle with. The Tremor uses 18-inch Dark Carbonized Gray wheels with Electric Spice accent pockets and 275/70R18 all-terrain tires. The larger sidewall and aggressive tread of the all-terrain tire are the first line of defense against off-road terrain; the electronic systems work with them, not instead of them.
Exterior: How to Identify a Tremor on the Road
The Tremor’s visual identity is built around the Electric Spice accent color and off-road-specific body modifications. Up front, the Tremor gets a unique off-road grille with auxiliary high beam lights integrated into the grille opening. LED fog lamps flank the lower fascia, which receives Electric Spice accent treatment. The overall effect is more aggressive and purposeful than the standard Expedition’s cleaner appearance.
The 18-inch wheel sizing is worth noting specifically because it is smaller in diameter than the 22-inch wheels on higher Expedition trims like Platinum. This is intentional - a smaller diameter wheel allows a taller tire for the same overall diameter, and taller sidewalls absorb impacts more effectively on rough surfaces. The Tremor is not trying to look like a Platinum; it is optimized for a different mission.
The Heavy-Duty Trailer Tow package includes a receiver and wiring harness, which is visible at the rear. The Tremor is available only in the standard-length body - not in the MAX extended configuration available on other Expedition trims.
"The Tremor changes the conversation for Expedition buyers who thought they had to choose between family capacity and genuine off-road capability. You do not have to choose anymore. The customers who have sat in it are surprised by how comfortable it is - and then they see the Rock Crawl button and understand this is a different kind of Expedition."

Interior: Electric Spice Details on a Full Leather Cabin
The Tremor interior starts with Black Onyx leather seating with Electric Spice contrast stitching and Tremor logo embossing on the front headrests. The standard Expedition content - three-zone climate, SYNC 4 with 24-inch panoramic display, and power-adjustable front seats - is all present. The Tremor adds its own off-road cluster screen showing pitch, roll, and drive mode information when off-road modes are engaged.
The available Driver’s Package on the Tremor is worth examining closely. It adds the 22-speaker B&O Unleashed audio system, power-deployable side steps that fold under the body when not in use, and a wireless charging pad. The B&O Unleashed system in the Expedition is one of the better factory audio systems available in any vehicle at this price point, and it is the same system found in the Platinum with the Driver’s Package. If audio quality matters, this is the path to it in a Tremor.
Tremor vs. Standard Expedition: The Summary
For buyers deciding between a well-equipped Active and the Tremor, the differences go beyond the price gap:
- Engine: 440 HP vs. 400 HP
- Off-road modes: Rock Crawl (Tremor exclusive) vs. no rock crawl
- Differential: Electronic locking rear (Tremor) vs. standard differential
- Suspension: Raised off-road tuned (Tremor) vs. standard
- Skid protection: Full underbody coverage (Tremor) vs. none
- Tires: All-terrain 275/70R18 (Tremor) vs. all-season 255/65R20
- Drivetrain: 4x4 standard only (Tremor) vs. 4x4 or 4x2
The Tremor costs more than the Active but brings meaningful hardware differences that are not available as options on lesser trims - the Rock Crawl mode and electronic locking differential are Tremor-only. For the buyer whose family needs a capable off-road vehicle and a comfortable daily SUV in the same package, there is no comparable alternative in the Ford lineup.

FAQ
Is the Expedition Tremor available in MAX length? No - the Expedition Tremor is available only in the standard-length body. The MAX extended configuration is available on Active, Platinum, and King Ranch.
Does the Expedition Tremor require 4x4? Yes - the Tremor is 4x4 only. There is no two-wheel-drive Tremor configuration.
What is Rock Crawl mode and how does it differ from Off-Road mode? Rock Crawl is a dedicated drive mode on the Tremor that engages the electronic locking differential and configures the AWD system for maximum traction on slow, technical terrain. Off-Road mode adjusts throttle and AWD for moderate off-road use but does not engage the locking differential or configure for crawl-speed operation the way Rock Crawl does.
Can the Expedition Tremor tow? Yes - the Heavy-Duty Trailer Tow package is standard on the Tremor, giving it the maximum towing capability available in the Expedition lineup. The 440-HP High Output engine also provides more towing reserve than the standard engine.
What is Trail Turn Assist on the Expedition Tremor? Trail Turn Assist applies braking to the inside rear wheel at low off-road speeds to help the Expedition make tighter turns on narrow trails. It effectively reduces the turning radius on technical terrain where the standard turning circle would require multi-point turns.
Is the Driver’s Package standard on the Tremor? No - the Driver’s Package (22-speaker B&O Unleashed, power-deployable running boards, wireless charging) is available on the Tremor but not standard. It adds meaningful audio and convenience content for buyers who want those features.
