Wheelbase and Overall Length
One of the most noticeable differences between the Jeep Wrangler JK and JKU is their size. This comes down to variance in wheelbase and overall length:
- The JK has a 95.4 inch wheelbase and an overall length of 164.3 inches.
- The JKU has a 116 inch wheelbase and an overall length of 186.6 inches.
That means the JKU has over 20 more inches of wheelbase and over 22 more inches of total length.
What does this equate to for real world use?
The JKU’s longer wheelbase improves ride quality and straight line stability. You’ll notice less bouncing around and swaying on uneven terrain or at highway speeds.
However, the shorter JK offers greater maneuverability and a tighter turning radius. It can squeeze through narrow off-road trails more easily. The JK also provides a more old-school, authentic Wrangler experience harkening back to its CJ origins.
So if tight trail driving is a priority, the more compact JK may be a better fit. But the JKU offers improved stability for most daily driving scenarios.
Interior Space and Seating
Let’s move inside the cabins. The size difference between the Wrangler JK and JKU directly impacts interior space and seating configurations:
- The JK has less rear cargo room and rear seat legroom due to its shorter length.
- The JKU gets additional cargo space behind the rear seat thanks to the longer wheelbase. This also translates to more rear legroom for passengers.
- The JK is only available as a 4-seater with a 2-person rear bench.
- The JKU can fit 5 passengers with a full rear bench that fits 3 adults across.
So the JKU is better suited if you need to fit adults in the back seat or carry more gear inside the cabin. Families that need that extra seating capacity will appreciate the JKU.
But if you rarely use the rear seats, the JK may be all you need. And some may prefer the more cozy feel of the JK’s interior layout.
Off-Road Capabilities
A huge part of the appeal of Wranglers is their off-road readiness. This is an area where the JK and JKU are nicely matched:
- Both have standard four-wheel drive systems able to handle rugged terrain and inclines.
- Their ground clearance, approach angle, and departure angles are identical.
- Water fording depth is the same at 30 inches on both models.
- Similar off-road oriented features are offered like the Command-Trac 4WD system, Trac-Lok anti-spin rear differential, and heavy-duty Dana axles.
While wheelbase affects on-road handling, it doesn’t limit the off-road abilities of the JKU. The capabilities are remarkably similar between the two in terms of ruggedness.
Some minor differences:
- The shorter JK may navigate certain tight or narrow trails better.
- The JKU’s longer breakover angle (the middle underside clearance) allows it to crest bumps and hills more easily.
But both deliver that legendary Wrangler off-road performance. Serious off-road enthusiasts will appreciate what either model can accomplish out on the trails.
Engine Options
Under their hoods, the JK and JKU Wranglers share the same engine choices:
- The standard 3.6L Pentastar V6 generating 285 horsepower and 260 lb-ft of torque.
- Optionally, a 3.8L V6 (the JK’s legacy powerplant) with 202 horsepower and 237 lb-ft of torque.
So you get identical horsepower and torque whether opting for the JK or JKU. Fuel economy is also similar between the two models.
The 3.6L V6 offers plenty of smooth power for highway driving and off-road crawls. The 3.8L V6 is a bit underpowered for the Wrangler’s weight but gets the job done.
In summary, your engine options and performance prospects are not limited by choosing the JK or JKU. Pick the Wrangler size you want based on wheelbase and interior space, not engine considerations.
Towing Capacity
How do these two Wranglers compare when it comes to towing boats, campers, or off-road toys?
Once again, the capabilities are evenly matched:
- The JK Wrangler can tow up to 3,500 pounds.
- As can the JKU Wrangler with its 3,500 pound tow rating.
Towing capacity is not increased with the JKU’s larger size. The vehicle chassis, engine power, and drivetrain components give both models the same respectable mid-size towing abilities.
Either the JK or JKU can pull a decent sized boat or pop-up camper without issue. So towing needs shouldn’t dictate your choice between the two Wrangler models.
Gas Mileage
With gas prices constantly fluctuating, fuel efficiency is top of mind for many buyers. Here’s how the mileage shakes out:
- The EPA estimate for the JK is 15 MPG city and 19 MPG highway when equipped with the standard 3.6L V6 engine and manual transmission.
- The JKU gets nearly identical mileage estimates of 15 city and 19 highway MPGs.
Real world fuel economy will vary based on driving style and conditions. But on paper, the JK and JKU have equivalent gas mileage despite the size difference.
This makes sense given they utilize the same engine options and gear ratios. The JKU’s larger size and weight don’t penalize it at the pumps.
If fuel economy is a priority, a 4-door Jeep won’t cost you much more to fill up than the 2-door.
Price Difference
Now for the bottom line – how much extra will it cost to upgrade from a Jeep Wrangler JK to the larger JKU model?
Here’s a look at the MSRP pricing:
- The entry-level Jeep Wrangler JK Sport starts around $28,000.
- Stepping up to the 4-door Wrangler JKU Sport, you’re looking at an MSRP starting around $31,000.
That’s around a $3,000 price difference between the base models.
As you go up through the higher trims like Sahara and Rubicon, expect to pay approximately $3,000-$4,000 extra for the JKU model at each level.
Why the price premium for the 4-door? The additional length, rear cargo room, and extra seat warrant the bump in cost. You’re gaining a lot of practical functionality for the money.
Both the short and long wheelbase Wranglers represent great value starting under $30k. But budget-focused buyers may want to stick with the more affordable JK.
