Fuel efficiency remains a top concern for buyers of used SUVs. With rising fuel costs and increasing environmental awareness, selecting a vehicle that balances utility with economy is more important than ever. Among the most popular used SUV options, the Jeep Renegade and Jeep Cherokee frequently appear on shopping lists. Both offer Jeep's rugged styling and off-road capability, but they serve different segments and exhibit distinct fuel economy characteristics. This article provides a detailed comparison of the fuel efficiency of these two models, covering historical data, real-world driving conditions, and practical advice for buyers.

Jeep Renegade: Urban Capability with Economy Focus

The Jeep Renegade debuted for the 2015 model year as a subcompact SUV, slotting below the Cherokee. Its boxy design and relatively light weight contribute to better aerodynamics for its size, and its powertrain options have consistently leaned toward efficiency. The Renegade is built on a platform derived from Fiat, which influences its handling and fuel economy.

Renegade Engine Options and Fuel Economy by Year

The used Renegade market primarily features two gasoline engines across model years 2015–2023:

  • 2.4L Tigershark I4 (2015–2023): Standard on most trims, this naturally aspirated engine produces 180 hp and 175 lb-ft of torque. Official EPA estimates are 22 city / 30 highway MPG for front-wheel-drive models, and 21 city / 29 highway MPG with four-wheel drive. Real-world reports often show combined averages between 24–26 MPG.
  • 1.3L Turbocharged I4 (2019–2023): Introduced with the 2019 facelift, this smaller turbo engine produces 177 hp and 200 lb-ft of torque. It improves efficiency to 24 city / 32 highway MPG (FWD) and 23 city / 30 highway MPG (4WD). Owners frequently achieve 28–30 MPG on highway trips.

Notable variations: The 2015–2016 Renegade with the 1.4L MultiAir Turbo (available only on early Sport and Latitude trims) offered 24 city / 31 highway MPG, but this engine was discontinued due to low take rates. Diesel options never reached the US market.

What Affects Renegade MPG in the Used Market

Used Renegades may have experienced engine issues—especially the 2.4L with oil consumption problems—that can degrade fuel economy. A well-maintained Renegade with the 1.3T or late-model 2.4L should return EPA-like numbers. Tire condition, drivetrain mode (Auto vs. 4WD Lock), and aftermarket accessories (roof racks, lift kits) also significantly impact efficiency.

Jeep Cherokee: More Space, More Trade-Offs

The Jeep Cherokee (KL generation, 2014–2022) is a compact SUV with a roomier cabin and greater cargo capacity than the Renegade. It offered a wider range of engines, including a V6, and came standard with the nine-speed automatic transmission. Fuel economy varies more across model years due to transmission calibration issues (especially 2014–2015) and engine choices.

Cherokee Engine Options and Fuel Economy by Year

  • 2.4L Tigershark I4 (2014–2022): Base engine produces 184 hp and 171 lb-ft. EPA estimates: 22 city / 31 highway MPG (FWD) and 21 city / 30 highway MPG (4WD). Real-world combined averages are about 23–25 MPG. Many owners report lower numbers if the nine-speed transmission fails to reach top gear in city driving.
  • 3.2L Pentastar V6 (2014–2022): Produces 271 hp and 239 lb-ft. EPA: 20 city / 29 highway (FWD) and 19 city / 28 highway (4WD). Real-world highway MPG can reach 26–28 MPG depending on driving habits. The V6 is the better choice for towing (up to 4,500 lbs) but hurts overall fuel economy.
  • 2.0L Turbocharged I4 (2018–2022): Available on higher trims, this engine delivers 270 hp and 295 lb-ft. EPA: 22 city / 31 highway (FWD) and 21 city / 30 highway (4WD). Real-world combined MPG often beats the V6 by 2–3 MPG.

Diesel note: A 2.0L EcoDiesel was offered from 2014–2018, rated at 27 city / 37 highway MPG (FWD) and 26 city / 36 highway (4WD). However, these are rare and require special maintenance (DEF fluid, diesel emissions systems). They can be excellent used buys if service history is solid.

Cherokee Fuel Economy Caveats

The Cherokee's nine-speed transmission earned early criticism for clunky shifting and inability to hold overdrive gear, which hurt real-world MPG. Later model years (2016+) recalibrated the software, improving both drivability and efficiency. Used buyers should prioritize 2017 or newer Cherokees for best fuel economy. Additionally, the Cherokee's heavier curb weight (~3,800 lbs for 4WD V6) vs. Renegade (~3,200 lbs) means it uses more fuel in stop-and-go traffic.

Head-to-Head Fuel Efficiency Comparison

To compare apples to apples, we examine the most common powertrains on the used market:

Model / Engine EPA City MPG EPA Highway MPG Real-World Combined
Renegade 2.4L 4WD 21 29 24
Renegade 1.3T 4WD 23 30 26
Cherokee 2.4L 4WD 21 30 23
Cherokee 3.2L 4WD 19 28 21

Key takeaways: The Renegade consistently beats the Cherokee by 2–4 MPG in real-world combined driving. The gap widens with the Renegade 1.3T versus the Cherokee V6. However, the Cherokee with the 2.4L i4 is only about 1 MPG behind the Renegade 2.4L—a negligible difference if you need the extra passenger and cargo room.

Factors That Influence Real-World MPG in Used Jeeps

No two used Jeeps perform identically. Here are the most impactful variables:

  • Tire condition and pressure: Underinflated tires or oversize all-terrain tires can reduce MPG by 5–10%. Inspect tread depth and ensure proper inflation (check door jamb sticker—do not exceed max sidewall).
  • Drivetrain mode: Running the Renegade's Active Drive in 4WD Lock or using the Cherokee's Selec-Terrain in Sand/Mud will engage the rear axle more often, lowering fuel economy. Use Auto mode for daily driving.
  • Maintenance history: Clogged air filters, old spark plugs, worn oxygen sensors, and dirty MAF sensors all degrade fuel economy. A used Jeep with no service records should receive a tune-up.
  • Modifications: Roof racks, lift kits, and heavier wheels increase drag and weight. Even a stock roof crossbar can reduce highway MPG by 1–2 MPG.
  • Driving style: Aggressive acceleration and high-speed cruising (above 70 mph) disproportionately hurt the Cherokee’s V6 more than the Renegade’s smaller engines.
  • Climate and terrain: Cold weather, winter blend fuel, and hilly routes reduce MPG for both models. The Renegade’s smaller engine may require more frequent downshifts on steep grades, partially offsetting its weight advantage.

Which Used Jeep Offers Better Value for Fuel Economy?

Value involves more than MPG alone. A used Renegade (2019–2023) with the 1.3T offers the best fuel efficiency in the Jeep lineup, with prices typically $15,000–$22,000. However, its cabin is smaller, and rear seat legroom is tight for adults. A used Cherokee (2017–2022) with the 2.4L offers comparable city MPG and better highway comfort, with similar pricing. The Cherokee V6 is the right choice if you need towing or quicker acceleration—just accept 2–3 MPG penalty.

For maximum fuel savings, consider the rare Cherokee 2.0L Turbo or the EcoDiesel (if you can find one). Both outperform the Renegade on the highway (33–37 MPG) but cost more upfront. On a cost-per-mile basis, a Renegade 1.3T has an advantage in urban settings, while a Cherokee 2.4L is more versatile.

Resale Value and Depreciation

The Renegade depreciates faster than the Cherokee, partly due to initial low demand. This means lower entry prices for used buyers, but also lower trade-in value later. Fuel efficiency does not significantly affect resale for these models; condition, mileage, and service history matter more. However, the Renegade’s lower fuel costs over five years could offset its higher depreciation.

Tips for Maximizing Fuel Efficiency in a Used Jeep SUV

Whether you choose a Renegade or Cherokee, follow these steps to get the best MPG:

  • Verify the transmission software is up to date. For 2014–2016 Cherokees, ensure the TCM recall (and any subsequent updates) was performed. Dealers can check this with your VIN.
  • Use the recommended octane fuel. The Renegade 2.4L and Cherokee 2.4L run on regular 87 octane. The 1.3T Renegade and 2.0T Cherokee require premium 91 octane for optimal performance and efficiency. Using regular may reduce MPG by 2–3.
  • Reduce idle time. Both Jeeps do not have start-stop systems on older models. Extended idling in traffic hurts real-world economy—turn off the engine if waiting more than 30 seconds.
  • Minimize use of roof racks and cargo boxes. Remove them when not needed. A roof box can decrease highway MPG by 10–15% at 70 mph.
  • Keep up with regular maintenance. Change oil every 5,000–7,500 miles, use full synthetic, replace air filters annually, and flush coolant per schedule. Poor maintenance can cost you 1–4 MPG.
  • Monitor tire pressure monthly. Use the pressure listed on the driver’s door label. Don’t rely on dashboard TPMS alone—it only warns at 25% underinflation.

Conclusion

Fuel efficiency should not be viewed in isolation. The Jeep Renegade offers the best economy among used Jeeps, particularly with the 1.3L turbo engine, and is an ideal city runabout. The Jeep Cherokee provides more interior space, stronger towing capability, and a more refined highway ride, but at a cost of 2–4 MPG on average. For most used buyers, a well-maintained Cherokee with the 2.4L i4 (2017 or newer) strikes the best balance—roomy enough for families yet only slightly thirstier than a Renegade. Those who prioritize absolute fuel savings and drive primarily in urban environments will find the Renegade hard to beat.
