Overview of the 2019 and 2021 Jeep Models

Jeep remains one of the most recognized off-road brands, with the Wrangler and Grand Cherokee leading sales for years. When shopping for a used Jeep, the 2019 and 2021 model years represent two distinct points in the brand’s evolution. The 2019 models carried forward the proven capabilities that made Jeep famous, while the 2021 lineup introduced significant technology and powertrain updates. Choosing between them requires a close look at what changed, what stayed the same, and how those differences affect daily driving, off-roading, long-term reliability, and resale value. This comparison covers the most popular Jeep models — the Wrangler and Grand Cherokee — to give you a complete picture of what each model year offers.

Engine Options and Powertrain Upgrades

The most important mechanical difference between the 2019 and 2021 Jeeps lies under the hood. While both years share many powertrain choices, the 2021 models gained several new engine options and transmission refinements that improve performance, efficiency, and towing capacity.

2019 Jeep Wrangler (JL) Powertrains

The 2019 Wrangler came with two main gasoline engines:

  • 3.6L Pentastar V6 – 285 hp, 260 lb-ft of torque, paired with a 6-speed manual or 8-speed automatic transmission.
  • 2.0L Turbocharged I4 – 270 hp, 295 lb-ft of torque, available only with an 8-speed automatic and a mild-hybrid eTorque system that provided smoother stop-start and a slight torque boost at low speeds.

Both engines delivered capable acceleration for on-road and off-road use. The optional 8-speed automatic was a major upgrade over the older Wrangler models, improving both shift smoothness and fuel economy. The 3.6L V6 remained the preferred engine for traditionalists, while the turbo I4 appealed to those wanting better low-end torque for rock crawling.

2021 Jeep Wrangler (JL) Powertrains

For 2021, Jeep added two important powertrain choices, keeping the existing gasoline engines largely unchanged:

  • 3.6L Pentastar V6 – Same 285 hp, 260 lb-ft, now available with the 8-speed automatic on all trims except the base Sport with manual. The eTorque system became standard on automatic-equipped models, improving stop-start refinement and giving a slight low-speed torque boost.
  • 2.0L Turbocharged I4 with eTorque – The same 270 hp engine, now with an improved eTorque system that delivered 90 lb-ft of additional torque for smoother launches and slightly better city fuel economy.
  • 3.0L EcoDiesel V6 – 260 hp and 442 lb-ft of torque. This engine dramatically changed the Wrangler’s character, offering class-leading torque for towing (up to 3,500 lbs) and exceptional highway fuel economy. The diesel was only available with the 8-speed automatic.
  • 4xe Plug-in Hybrid – Launched in late 2020 as a 2021 model, the 4xe combined a 2.0L turbo I4 with two electric motors and a 17.3 kWh battery pack. Total system output was 375 hp and 470 lb-ft of torque, making it the most powerful Wrangler ever. It offered up to 21 miles of electric-only range and significantly improved fuel economy for daily commuting.

The addition of the EcoDiesel and 4xe options made the 2021 Wrangler lineup far more versatile. Buyers who needed maximum torque for heavy off-road loads could choose the diesel, while those wanting a compliant daily driver with low running costs could opt for the plug-in hybrid.

2019 Jeep Grand Cherokee (WK2) Powertrains

The 2019 Grand Cherokee continued with three main engine options, all paired with the 8-speed automatic transmission:

  • 3.6L Pentastar V6 – 295 hp, 260 lb-ft, standard on Laredo, Limited, and Trailhawk trims.
  • 5.7L Hemi V8 – 360 hp, 390 lb-ft, available on Limited, Overland, and Summit trims.
  • 6.4L SRT V8 – 475 hp, 470 lb-ft, exclusive to the high-performance SRT model.

The 2019 Grand Cherokee offered a balanced mix of power and efficiency, but the absence of a diesel option meant heavy-towing buyers had to rely on the V8’s fuel penalty. The 8-speed automatic remained one of the best in the segment, delivering smooth shifts and responsive paddle control.

2021 Jeep Grand Cherokee (WK2) Powertrains

For 2021, the Grand Cherokee received a mid-cycle refresh that brought new technology and a new top engine:

  • 3.6L Pentastar V6 – Same output of 295 hp, now with stop-start as standard on most trims.
  • 5.7L Hemi V8 – Unchanged at 360 hp, but now available with the eTorque mild-hybrid system on certain trims to improve fuel economy by about 1-2 mpg.
  • 6.4L SRT V8 – Same as 2019, with unchanged power figures.
  • 6.2L Supercharged V8 (Trackhawk) – 707 hp, 645 lb-ft, still offered as the ultimate performance SUV. For 2021, the Trackhawk received updated software for slightly quicker throttle response.

While the 2021 Grand Cherokee didn’t see drastic engine changes, the addition of eTorque on the V8 was a meaningful improvement, providing smoother idle-stop transitions and slightly better fuel economy for those who tow regularly. The 2021 model also introduced a new L-series model (the three-row Grand Cherokee L) with an all-new architecture, but that model is not included in this used-car comparison as it differs substantially from the 2019 version.

Fuel Economy and Efficiency

Fuel costs matter, especially for a heavy off-road SUV. The 2021 models generally edge ahead thanks to better transmissions, mild-hybrid systems, and the diesel option.

Engine 2019 City/Highway 2021 City/Highway Improvement
3.6L V6 auto 19 / 24 20 / 25 (with eTorque) +1 mpg
2.0L turbo I4 auto 21 / 24 22 / 26 +1-2 mpg
3.0L EcoDiesel N/A 22 / 29 Significant
4xe (plug-in hybrid) N/A 49 MPGe + 20 miles EV Best efficiency

For the Grand Cherokee, the 2021 models with the V8 eTorque saw small but real gains:

  • 5.7L V8 (no eTorque) – 2019: 14 city / 22 highway mpg; 2021: same for non-eTorque models.
  • 5.7L V8 with eTorque – 2021: 15 city / 22 highway mpg. The small improvement matters in stop-and-go traffic.
  • 3.6L V6 – 2019: 19 city / 26 highway; 2021: same with start-stop.

If fuel efficiency is a priority, the 2021 Wrangler EcoDiesel or 4xe are clear winners, while the 2021 Grand Cherokee V8 with eTorque offers a modest benefit over the 2019 version.

Off-Road Capability and 4×4 Systems

Jeep’s reputation for off-road prowess remains strong in both years, but the 2021 models introduced some subtle improvements, especially in the Wrangler.

Wrangler: Proven Rock Crawling Gets Better

Both the 2019 and 2021 Wranglers share the same JL architecture with solid front and rear axles (Dana 44 in the Rubicon), coil-spring suspension, and available electronic locking differentials. Key differences:

  • Front stabilizer bar disconnect – Available on Rubicon trims both years, but the 2021 model added an optional electronic sway bar disconnect on the Sahara and Mojave trims.
  • Off-road pages – The 2021 Wrangler includes an upgraded off-road display showing pitch, roll, tire pressure, and four-wheel-drive status on the larger touchscreen.
  • Tow rating – The 2021 diesel boosted maximum towing capacity from 3,500 lbs (gas models) to 3,500 lbs as well (diesel and 4xe have same limit), but the 2021 models are better equipped for heavy trailers thanks to the diesel’s torque curve.

For serious off-roaders, the 2019 Rubicon remains a capable choice. The 2021 model adds convenience with the off-road pages and the diesel’s low-end grunt, but the core mechanical capability is very similar.

Grand Cherokee: Trailhawk Trim Shines

The 2019 and 2021 Grand Cherokee Trailhawk both feature Quadra-Drive II with a rear electronic limited-slip differential, air suspension for up to 10.8 inches of ground clearance, and skid plates. The 2021 model gained a new Selec-Terrain system that adds a “Sand” mode, but otherwise the off-road capability is nearly identical. The 2021 model’s eTorque on the V8 provides smoother throttle modulation on slippery trails, but the difference is subtle.

Interior Quality, Technology, and Comfort

Technology moved quickly between 2019 and 2021, especially in infotainment and safety. The interior materials also saw incremental improvements.

Infotainment: Uconnect Gets an Upgrade

The 2019 Wrangler and Grand Cherokee used the fourth-generation Uconnect system with a 7-inch (standard) or 8.4-inch (optional) touchscreen. The system supported Apple CarPlay and Android Auto, Bluetooth, and satellite radio. The 2021 models upgraded to Uconnect 4C with a faster processor, crisper graphics, and in the Wrangler, an available 8.4-inch screen with navigation that included real-time traffic and weather. The 2021 Grand Cherokee also offered a new 10.1-inch touchscreen as an option on high-end trims.

Key infotainment highlights for 2021:

  • Wireless Apple CarPlay and Android Auto – Standard on 2021 Wrangler and available on Grand Cherokee. The 2019 models required a cable.
  • Voice recognition improvements – The 2021 system recognizes more natural language commands and can adjust climate and navigation settings.
  • Over-the-air updates – 2021 models can receive system updates via Wi-Fi, keeping the software current without a dealer visit.
  • Off-road camera – The 2021 Wrangler Rubicon got a new front-facing camera that helps line up the tires on obstacles, a feature not available in 2019.

For buyers who value seamless smartphone integration, the 2021 models’ wireless connectivity is a strong selling point.

Material Quality and Seat Comfort

The 2019 Wrangler still feels relatively spartan inside, with lots of hard plastic on the dashboard and door panels. The 2021 model improved touch points: soft-touch materials appeared on the upper door panels on Sahara and Rubicon trims, and the seats gained more cushioning for long highway drives. The 2021 Grand Cherokee also benefited from a refreshed interior with available Nappa leather, open-pore wood trim, and a sleeker center console design.

One notable update for the Wrangler is the 2021 availability of a power liftgate on four-door models — a feature the 2019 lacked entirely. The 2021 Grand Cherokee also received hands-free power liftgate functionality on Limited and above, a practical upgrade for families.

Safety and Driver Assistance

Safety technology advanced considerably between these model years. The 2019 Wrangler and Grand Cherokee offered basic driver aids, while the 2021 models added a suite of active safety features that make them more competitive with modern crossovers.

2019 Safety Equipment

  • Wrangler – Standard rearview camera, electronic stability control, hill-start assist, and available blind-spot monitoring with rear cross-traffic alert (on higher trims). No adaptive cruise control or lane-keeping assist.
  • Grand Cherokee – Standard rearview camera, parking sensors, and optional blind-spot monitoring. Adaptive cruise control was available as part of an optional group.

The 2019 Grand Cherokee earned a 5-star overall rating from the NHTSA (with 4-star frontal ratings). The 2019 Wrangler got mixed safety marks; it received a 4-star overall rating because of its boxy design and lack of a standard backup camera on base trims (though it was standard on most models).

2021 Safety Upgrades

  • Wrangler – Standard rearview camera, electronic stability control, hill-start assist, and now standard blind-spot monitoring with rear cross-traffic alert on all trims. Available for the first time: adaptive cruise control with stop-and-go, forward collision warning with automatic emergency braking, and lane-departure warning. The 2021 Wrangler also added a new front airbag and improved side curtain airbag deployment.
  • Grand Cherokee – Standard safety suite includes forward collision warning with automatic emergency braking, adaptive cruise control with stop-and-go, lane-departure warning, and active lane-keeping assist on most trims. The 2021 model also introduced a front parking camera and improved night vision (optional on Summit).

Safety ratings for the 2021 Wrangler improved to a 5-star NHTSA overall rating (with 5-star side impact). The 2021 Grand Cherokee retained its 5-star rating and added a Top Safety Pick+ award from the IIHS when equipped with specific headlights.

If you prioritize active safety, the 2021 model is the clear choice. The 2019 models lack automatic emergency braking and adaptive cruise control on both the Wrangler and Grand Cherokee (except on the Grand Cherokee with the optional group).

Pricing, Resale Value, and Ownership Costs

Cost is often the deciding factor. The 2019 models are significantly cheaper upfront, but the 2021 models may retain more value and offer lower maintenance costs in the near term.

Average Used Prices (as of early 2025)

  • 2019 Jeep Wrangler Unlimited (4-door) – $28,000–$36,000 depending on trim and mileage.
  • 2021 Jeep Wrangler Unlimited – $35,000–$45,000. The 4xe and Rubicon trims command higher prices.
  • 2019 Jeep Grand Cherokee (Laredo to Summit) – $22,000–$38,000.
  • 2021 Jeep Grand Cherokee – $30,000–$48,000.

The price gap averages about $7,000–$10,000 for comparably equipped models. That difference covers the cost of the upgraded technology, better safety levels, and newer powertrain options.

Resale Value

Jeep vehicles historically hold their value well, but the 2021 models are expected to depreciate slightly faster in the near term because they were more expensive new. However, the 2021 Wrangler’s 4xe and diesel variants may hold value better due to their desirability among enthusiasts and fuel-conscious buyers. The 2019 models have already taken their biggest depreciation hit and may offer more stability if you plan to own the vehicle for many years.

According to data from Kelley Blue Book, the 2021 Jeep Wrangler retains about 60-65% of its original MSRP after 4 years, while the 2019 model retains around 55-60% after 6 years. The 2021 Grand Cherokee retains about 50-55% after 4 years, compared to 45-50% for the 2019 model after 6 years. For buyers who trade vehicles frequently, the newer model offers better trade-in flexibility.

Maintenance and Reliability

The 2019 models are older and thus more likely to need repairs sooner. Common issues reported for 2019 Wranglers include steering damper problems (affecting stability) and some early transmission software glitches. The 2021 models resolved many of those initial teething problems. For example, the 2021 Wrangler received a reinforced steering damper and updated software for the 8-speed transmission, improving both on-road feel and shift quality.

The 3.6L V6 engine, used extensively across both years, has a solid reliability record if oil changes are kept on schedule. The 2.0L turbo is also dependable. The EcoDiesel in the 2021 Wrangler has been reliable overall, though some owners have reported emissions-related sensor issues. The 4xe hybrid system appears robust, but its complexity means higher repair costs if something fails out of warranty.

For the Grand Cherokee, both model years share similar reliability. The 2021 model’s eTorque system adds complexity but rarely fails. Overall, the 2021 models benefit from refinements made during the 2019-2020 production run, so they tend to have fewer minor quality issues.

Which Model Year Is Better for You?

The answer depends on your priorities and budget. Here’s a breakdown for different buyer profiles.

Choose the 2019 If You:

  • Are on a tighter budget – The lower purchase price leaves money for modifications or a longer ownership period.
  • Prefer a simpler, more analog driving experience – The 2019 models lack complex hybrid systems and active safety features, which may appeal to purists.
  • Plan to heavily modify the vehicle – An older, cheaper base vehicle with fewer integrated electronics is easier to upgrade with aftermarket parts.
  • Don’t need the latest tech or safety aids – If you rarely use CarPlay and don’t care about adaptive cruise control, the 2019 is perfectly capable.

Choose the 2021 If You:

  • Want the best fuel economy and torque options – The EcoDiesel and 4xe are game changers for daily driving and towing.
  • Value modern safety and driver assistance – The standard blind-spot monitoring, automatic emergency braking, and adaptive cruise control make the 2021 much safer for highway trips.
  • Prefer wireless smartphone integration – The wireless CarPlay/Android Auto is a convenience very hard to replicate in older models.
  • Plan to keep the vehicle for 5+ years – The newer model will likely have lower total ownership costs thanks to fewer repairs and better resale value after the first few years.
  • Live in a city or commute – The 4xe’s electric range helps you avoid gas stations, and the improved interior insulation makes the cabin quieter.

Final Thoughts

Both the 2019 and 2021 Jeep model years represent excellent used vehicles, but they serve different needs. The 2019 models deliver rugged capability at a lower price, while the 2021 models bring updated technology, modern safety features, and two groundbreaking powertrains — the EcoDiesel and 4xe — that redefine what a Jeep can be for everyday use. If your budget allows, the 2021 is the more refined and forward-looking choice. For those who prioritize value and simplicity, a well-maintained 2019 remains a fantastic off-road companion.
