Performance and Specifications
Power Output and Torque Figures
The Wrangler offers four main engine options.
Below is a breakdown of their horsepower and torque:
| Engine Type | Horsepower | Torque (lb-ft) |
|---|---|---|
| 2.0L Turbo I4 | 270 hp | 295 lb-ft |
| 3.6L V6 | 285 hp | 260 lb-ft |
| 4xe 2.0L Turbo Hybrid | 375 hp | 470 lb-ft |

The V6 is known for its smooth operation and proven reliability.
The V8 delivers the highest output, matching the 4xe in torque but with more horsepower.
Gearbox and Drive Systems
All powertrains use an 8-speed automatic transmission.
The V6 model in this comparison uses a part-time 4WD system, while the 392 V8 comes with full-time 4WD.
The 8-speed transmission is a major improvement over the Wrangler’s older 5-speed, offering smoother shifts and better drivability.
Both setups handle large tires well, especially with the right axle gearing.
Differential Ratios and Low-End Performance
The V6 Rubicon in this test runs a 4.88 axle ratio, providing stronger low-end response for 35-inch tires.
The 392 V8 Rubicon uses a 4.56 axle ratio, which still offers strong performance but at slightly lower engine speeds on the highway.
Lower gearing in the V6 helps with acceleration and off-road control, though it increases RPMs during highway driving.
Both setups are factory-regeared for their tire size, making them ready for off-road use without aftermarket changes.
Reliability and Service Life
Established Performance History
The 3.6L V6 has been in the Wrangler lineup for many years, giving it a long record of dependable use. Owners often note that it runs smoothly and delivers consistent performance. Its proven track record makes it a familiar choice for those who value stability over newer, less-tested options.
Longevity of Turbocharged Engines
The 2.0L turbocharged engine offers strong low-end torque and handles larger tires well, even at higher elevations. However, turbocharged engines often have a shorter service life compared to naturally aspirated ones. While many drivers report reliability similar to the V6, this remains a factor to weigh for long-term ownership.
Fuel economy impact with larger tires:
| Engine | Typical MPG with 35–37″ tires | Notes |
|---|---|---|
| 2.0L Turbo | ~12 mpg | Greater drop in efficiency |
| 3.6L V6 | 14–16 mpg (some lower) | Less affected by tire size |
Durability of the Hybrid Setup
The 4xe hybrid pairs a turbo 2.0L engine with electric power for high output. While it delivers strong torque, its long-term durability is less established compared to the V6. Owners considering this option should account for both the turbocharged engine’s traits and the additional complexity of hybrid components.
Fuel Use and Performance
Mileage Results with Bigger Tires
When equipped with 35-inch tires, both the 3.6L V6 and the 2.0L turbo see lower fuel economy.
- 2.0L Turbo: Many owners report around 12 mpg with 35s or 37s.
- 3.6L V6: Drivers often see 14–16 mpg under similar conditions, with some reaching slightly higher when driving conservatively.
The drop in efficiency is expected because larger tires add weight and rolling resistance. The effect is more noticeable in the turbo engine, which tends to lose more mpg than the V6 when upsized tires are installed.
Effect of Lower Axle Ratios
Both test vehicles use lower axle ratios to help move the larger tires:
| Engine | Axle Ratio |
|---|---|
| 3.6L V6 | 4.88 |
| 6.4L V8 | 4.56 |
Lower gearing improves low-speed power and drivability with heavy tires. However, it can raise engine rpm at highway speeds, which may reduce fuel efficiency. Around town, the impact is minimal thanks to the 8-speed transmission, but on the highway, the higher rpm is more noticeable.
Hybrid Compared to Gas-Only Engines
The Wrangler 4xe hybrid combines a 2.0L turbo with electric motors for 375 hp and 470 lb-ft of torque. While it offers strong output, its long-term fuel savings depend on driving habits and charging access. Gas-only options like the V6 and V8 avoid the need for charging but rely entirely on fuel, making their mpg more sensitive to tire size and gearing changes.

Tire Size and Grip
The 35-inch tires provide more ground clearance and better traction on rough terrain. The lower gearing in the V6 model helps maintain power delivery when moving the larger tires, especially at low speeds. While these tires improve off-road performance, they also increase rolling resistance, which can reduce fuel economy.
Fuel economy impact (based on driver reports):
- V6 with 35s: ~14–16 mpg for typical driving
- Turbo 4-cylinder with 35s/37s: ~12 mpg in many cases
Ride Feel and Cabin Comfort
The current Wrangler generation offers a smoother ride than older models, thanks in part to the 8-speed automatic transmission. Steering, suspension, and overall handling feel more refined, making it easier to drive daily. Added cabin insulation, including optional roof insulation, reduces wind and tire noise compared to past versions.
While it still has the characteristic Jeep noise levels on the highway, the upgrades make it more comfortable for long drives. Around town, the gearing changes have little downside, but at highway speeds, the lower gears keep the engine at higher RPMs. This trade-off benefits off-road control while slightly affecting highway efficiency.
