2026 Jeep Grand Wagoneer Specs Hyannis

420 horsepower, 468 lb-ft and 36.6 inches of third-row legroom are the same on all seven configurations. This page holds the published specifications for the 2026 Grand Wagoneer and Grand Wagoneer L, arranged around the question the numbers answer unusually clearly: does your choice change this one? On most vehicles that varies line by line. Here only four choices move anything at all: wheelbase, drivetrain, suspension and axle ratio. Everything else holds steady from the $63,995 configuration to the $100,310 one.

Each section below flags what is fixed before listing what moves. Where a figure depends on how the vehicle is equipped, the qualifying condition sits with the number rather than in a footnote. For what each configuration costs and includes, see the trims compared page; for the lineup in plain terms, the model overview.

Engine Specifications

Fixed across the entire range. There is one engine and one transmission, and they do not change between the $63,995 configuration and the $100,310 one. What does change is what you bolt behind them: the transfer case and the axle ratio are both options.

The axle ratio is the line to watch, because it is the one entry in this table that changes what the vehicle is rated to pull. Driveline detail in full sits on the engine and performance page.

Exterior Dimensions

Wheelbase moves length. Suspension moves height and every angle. Width is constant. So is the roof height within a tenth of an inch. The figure most often quoted wrongly for this vehicle is ground clearance, because it has two legitimate values depending on which suspension is underneath.

Now the figures the suspension controls. Every number in the right-hand column below requires Quadra-Lift air suspension raised into its Off Road 2 setting, and all of them are measured on the 275/55R20 tire. A single unqualified ground-clearance figure for this vehicle is not a real specification.

Two more suspension-dependent figures matter for loading rather than clearance, and they are the ones nobody quotes. Load floor height is 34.0 inches on the standard suspension and on air suspension at normal ride height, dropping to 32.5 inches with the air suspension lowered in Park. Sill step height follows the same pattern: 22.9 inches normally, 21.3 inches with the vehicle knelt.

Curb Weight and GVWR by Configuration

Weight is one of the few places the trim badge makes a real difference, because equipment content adds mass. Both figures below rise together, which is why payload does not change.

Interior Dimensions

Nothing in this section changes with wheelbase. That is the single most misunderstood fact about the Grand Wagoneer L, so it is worth stating before the table: every occupant measurement below is identical in the 123-inch car and the 130-inch one. The only variable here is the sunroof, which costs headroom at all three rows.

Total SAE interior passenger volume is 182.4 cubic feet. Seating is seven as standard, with second-row captain's chairs, or eight with the optional second-row bench, and that choice is open on every configuration.

Cargo Volume

Here is where the extra wheelbase finally shows up, and it shows up in exactly one place.

Fold the seats in the short-wheelbase Grand Wagoneer and the space grows to 70.8 cubic feet behind the second row, then 116.7 cubic feet behind the first, which is its maximum. Those two measurements are published for the short wheelbase only: Jeep splits just the behind-third-row line by body for 2026, and this page carries a previous-generation figure for neither. Seat-folding detail and how the space works in use are on the cargo and third row page.

Capacity and Capability

Payload varies by configuration, from 1,415 to 1,625 pounds, counting driver, passengers, cargo and options together. It tracks curb weight rather than price, so the Summit short wheelbase carries the most and the Limited L the least.

Towing varies too. It swings widely across the configurations below, and the axle ratio does most of the swinging.

The 3.92 axle behind the top two rows arrives by either of two routes: the Heavy-duty Trailer Tow package, which requires four-wheel drive and is optional on every configuration, or the Upland package, which bundles the same axle. Gross combined weight rating, properly equipped on the 4x4 3.92-axle build, is 15,000 pounds, or 16,500 pounds in Max Tow form, on both wheelbases. Maximum tongue weight is 820 pounds, or 981 pounds with Max Tow, on the short wheelbase, and 793 or 945 pounds on the L.

Two thresholds from the owner's manual are worth knowing before you hitch anything up: trailer brakes are recommended above 1,000 pounds and required above 2,000 pounds, and a weight-distributing hitch is recommended once gross trailer weight reaches 5,000 pounds. Load-by-load detail is on the towing capacity page.

Wheels, Tires and Axles

Trim-dependent, and it is the most visible variable on the list. Diameter climbs from 18 to 22 inches as you move up, and the Upland package is the only one that swaps road-biased rubber for all-terrain.

Axle hardware behind those wheels: an 8.5-inch ring gear up front, running an open differential, and a 10.2-inch ring gear at the rear carrying a limited-slip as standard. Specify the electronic limited-slip differential and the rear axle changes with it.

Fuel Economy and Range

Drivetrain and wheelbase both move this, but only by a point or two. One quirk in the EPA data is worth pointing out because it looks like a typo and is not: the rear-drive L certifies identically to the rear-drive short car. Only the four-wheel-drive L gives anything up.

All four configurations are certified on regular gasoline, and the ratings above are published at fueleconomy.gov, which is the source of record for this model because Jeep published no EPA figures of its own at launch. Fuel tank capacity is 26.5 gallons on the short wheelbase and 30.5 gallons on the Grand Wagoneer L.

Key Features by Trim

A short decision grid across the three underlying model trims. Not standard means the item is not fitted as standard equipment on that trim; it does not mean the item is unavailable somewhere in the range. The seven purchasable configurations and their packages are broken out on the trims compared page.

Safety and Compliance

Every Grand Wagoneer leaves the factory with Active Driving Assist fitted. The wording Jeep uses for it is precise and worth repeating exactly: a hands-on-wheel, eyes-on-road system. It will hold the vehicle in its lane on roads it recognises while managing speed and braking, but your hands belong on the wheel throughout. No hands-free highway system is offered on this vehicle at any price.

Jeep counts over 170 standard and available safety and security features across the vehicle. Crash-test results exist from both rating bodies and they are mixed: NHTSA gives four stars overall, and IIHS rates the updated moderate overlap front test Marginal, driven by rear-passenger chest performance, alongside Good results elsewhere. Every result, adverse ones included, with links to read them at the rating bodies directly, is published on the technology and safety page.

Warranty Coverage

The rust-through line is the one to read twice if the vehicle will live near the water, since salt reaches the underbody from the road in winter and from the air year-round. Note also that no complimentary scheduled maintenance program exists for 2026 Jeep vehicles; service intervals and what coverage actually pays for are on the maintenance schedule page.

What These 2026 Grand Wagoneer Numbers Mean in Practice

Specifications only matter where they meet something in the real world: a garage opening, a parking space, a ramp, a tailgate you have to lift a cooler over. Translating the figures above:

Two of those lines matter more on Cape Cod than they would inland. The turning circle is the one owners notice first, in a packed lot at Craigville Beach in July or backing out of a narrow driveway that was laid out for a 1970s wagon. The load floor height is the one that pays you back every weekend, whether the bikes are going on the Cape Cod Rail Trail or the coolers are going to Old Silver Beach in Falmouth.

If you are weighing the long body against the short one, the honest advice is to measure before you commit rather than after. Bring the dimensions that constrain you, the garage opening, the driveway length, the trailer tongue, and we will tell you which body clears them. We are on Yarmouth Rd in Hyannis.

Specifications FAQs

Which 2026 Grand Wagoneer specifications actually change between trims?

Fewer than most shoppers expect. Curb weight, GVWR and payload all move with equipment content, wheels grow from 18 to 22 inches, and tire fitment changes. Everything else on this page is set by wheelbase, drivetrain, suspension or axle ratio rather than by trim badge. Power, torque, every interior measurement and the transmission are identical across all seven configurations. Payload is not: it runs from 1,415 to 1,625 pounds and tracks curb weight rather than price.

How much cargo space is behind each row?

The short-wheelbase Grand Wagoneer measures 27.9 cubic feet behind the third row, 70.8 behind the second and 116.7 behind the first, the last being its maximum with every rear seat folded. For the Grand Wagoneer L, the figure Jeep splits out by body is 42.6 cubic feet behind the third row, which is what this page carries.

What is the turning circle of a 2026 Grand Wagoneer?

40.2 feet curb to curb on the 123-inch wheelbase, and 42.2 feet on the 130-inch Grand Wagoneer L. That two-foot difference is the most frequently underestimated cost of choosing the longer body.

How low does the tailgate sit for loading?

Load floor height is 34.0 inches on the standard suspension, and the same on air suspension at normal ride height. With Quadra-Lift air suspension the vehicle kneels in Park to 32.5 inches. Sill step height follows, at 22.9 inches normally and 21.3 inches knelt.

Does the panoramic sunroof reduce headroom?

Yes, at all three rows. Front headroom goes from 41.3 inches to 39.3, the second row from 40.0 to 38.4, and the third row from 39.0 to 38.5. The front row gives up the most, which is worth knowing if the tallest person in the household drives.

What octane does the 2026 Grand Wagoneer need?

Mid-grade 89 octane is recommended and regular 87 octane is acceptable. Premium is neither required nor recommended, and the EPA certified all four configurations on regular gasoline. Some third-party listings state premium for this engine. That is wrong for the 2026 car.

How big is the fuel tank?

26.5 gallons on the short-wheelbase Grand Wagoneer and 30.5 gallons on the Grand Wagoneer L. The longer body carries four extra gallons, which offsets part of its slightly lower EPA rating on four-wheel-drive builds.

Are there open recalls on the 2026 Grand Wagoneer?

Two, as of 18 July 2026. The earlier one is campaign 26V326000, issued 21 May 2026: its symptom is a rearview camera image that fails to appear, and the cause recorded is a front camera wiring harness that may not be properly connected. The later one is campaign 26V414000, issued 30 June 2026, and it concerns brake system control module software; where the defect is present, electronic stability control and electronic brake assist may be lost. Send us a VIN and we will tell you whether that particular vehicle is affected and whether its remedy has already been performed.
