Even though Jeep's venerable Wrangler was totally refreshed for 2018, 2020 brings significant changes under the hood. The Wrangler, considered by many to be the most capable off-road vehicle, returns in 2- and 4-door (Unlimited) configurations with removable doors, folding windshield and soft and hard top options. A pickup version badged Gladiator debuted in 2019. Enhancements for 2020 include the addition of a diesel engine and a mild-hybrid gasoline V6. Also new are special edition High Altitude packages for Sport and Sahara models. Wrangler has no direct competitors, however, vehicles with similar capabilities include the Land Rover Defender and Toyota 4Runner.
Standard engine is a 3.6-liter V6 engine that makes 285 horsepower. It pairs to either a 6-speed manual or 8-speed automatic. Also offered is a 270-horsepower turbocharged 2.0-liter 4-cylinder. It mates to the 8-speed automatic. Both the 4-cylinder and V6 are now available with Jeep's eTorque mild-hybrid system that is designed to smooth start/stop functionality and boost fuel economy. A 3.0-liter turbodiesel engine option is new for 2020. It makes 260 horsepower and 422 lb-ft of torque. It also mates to an 8-speed automatic.
Solid axles return front and rear and several 4WD systems are offered. Command-Trac is the base system. It offers rear-wheel drive, part-time 4WD high and low ranges. Rock-Trac adds electronic locking differentials front and rear as well as an electronic sway-bar disconnect. Selec-Trac offers rear-drive, full-time 4WD and part-time 4WD high and low ranges.
The model mix include Sport, Sport S, Sahara (4-door only) and Rubicon trims. Rubicon is the most capable off-road thanks to its special features, including shorter axle gearing and an electronically disconnecting roll bar. Features include blind-spot warning, Android Auto and Apple CarPlay integration and power operated canvas roof that slides back from front to rear. Designed to be the most premium Wrangler yet, the new High Altitude package adds custom interior trim and body enhancements.
The big news for 2020 is the availability of the first-ever diesel engine in the Wrangler. Why you ask? Well diesels are known for offering exceptional reliability, economy and, most importantly, torque. Dubbed EcoDiesel, the new engine doesn't disappoint. It provides solid acceleration and little of the diesel muss that is sometimes associated with the oil-burners -- as the can be called. The transmission shift points certainly come more quickly, but the engine provides smooth and seamless acceleration and incredible low-end torque that's so valuable when off-roading or towing. The available 2.0-liter 4-cylinder is also great fit in the Wrangler -- though it's a shame it isn't offered with a manual transmission. It provides great around-town acceleration and good passing punch. It's also smoother and more refined than the standard V6. Unloaded, expect a 0 to 60 MPH time of around 7.5 seconds. It mates well to the slick-shifting 8-speed automatic, providing smooth acceleration and timely downshifts in passing situations.
Jeep's Command-Trac 4WD system is a solid offering, but doesn't provide the flexibility of an automatic setting in 4WD mode. To get that, buyers must pay more for Selec-Trac. Either way, the Wrangler is the most capable out-of-the-box off-road vehicle available. Opt for the Rubicon, with its off-road goodies and extreme tires, and there's no trail to tough for Wrangler.
EPA estimates for the Unlimited with the 2.0-liter engine are 22 MPG city and 24 MPG highway. Certainly not impressive given the Wrangler's size but considerably better than Wranglers of yore. In routine suburban commuting expect to average close to the city number of 22 MPG, throw in a bit of gentle highway cruising and 24 MPG overall is quite possible. (Keep in mind that the Unlimited has a larger fuel tank than 2-door models.) Diesel models might average as high as 30 MPG overall. That's crazy good for a Wrangler and better than most compact crossovers.
Jeep has made massive improvements in the overall ride quality of the Wrangler, though it still isn't as smooth riding as crossover competitors like the CR-V or RAV4. That said, the ride quality is completely dependent on trim and options selection. The smoothest riding would be the Sahara Unlimited (with its street tires and longer wheelbase) and the bounciest ride would come from the 2-door Wrangler Rubicon. A but the Rubicon offer a perfectly acceptable ride on smooth pavement with little head toss or bounding that you might associate from Wranglers of yore.
There have also been massive improvements made to the on-road handling of the Wrangler. The steering feels more connected and direct -- though there is definitely more play than in crossover competitors. The brake pedal feels consistent and firm underfoot, but the action is a bit long. In a way, both the steering and braking are somewhat compromised to provide better control off road. Turning circle is admirably tight, but the big -tired Rubicon wanders a bit when driving straight. Crosswinds tend to be a handful as well.
Simply put, no stock vehicle is better off-road. Those that are serious trail nuts will only consider the Rubicon. It offers 33-inch tires, lockable front and rear differentials, and a disconnectable front stabilizer bar. The beauty of the Wrangler compared to other vehicles off road is the packaging. Impressive front and rear approach/departure angles and a high breakover combine with a shortish wheelbase to make it much more maneuverable than any other competitor.
Inside, the Wrangler contemporary and fresh and very functional. Materials are appropriate for the class and Jeep claims that the interior is waterproof. A large touch-screen dominates the design, but there are traditional analog gauges as well. The switchgear has been upgraded with more logical placement and a more robust feel. The integration of Apple Car Play and Android Auto is a huge plus as is the addition of blind-spot alert.
The upright front seats provide decent comfort and enough support to hold you in place off road. Rear seats are a bit less accommodating in terms of comfort, but at least head room is good. There's scant knee space in 2-door models, and adequate adult room in 4-door models. Getting in and out can be a bit of a challenge because of the tall step-in height. Also, the doors, aren't as large or substantial as competitors because of their removable design.
Interior noise levels can be high - especially on soft-top models. Fitted with the hard top, noise levels are acceptable but higher than in most competitors. A new tilt-and-telescope steering column helps drivers get comfortable behind the wheel and outward visibly is quite good expect dead astern where the tailgate-mounted spare blocks the view. Towing capacity is 2000 pounds on 2-doors and 3500 pounds on 4-door models.
Cargo capacity is scant on 2-door models and 4-doors offer just 32 cubic feet overall. The rear seats fold to increase cargo space but create an uneven load floor. The swing-out tailgate can be a problem as well (something that's compounded by the soft top that doesn't easily open at the rear). Interior storage is negligible with just a few open and covered bins throughout.
One additional note, Wrangler offers an impressive array of top options and overall configurations. As noted, the doors are removable and the windshield folds. There are three top options: A hard top with several removable sections, a canvas convertible top that is completely removable and a non-removable canvas center top that power-slides to the rear -- in essence a massive sunroof.
Bottom Line - Jeep totally overhauled Wrangler two years ago, but significant engine upgrades for 2020 make it even better. The Wrangler's combination of features, refinement (yes refinement) and off-road ability are simply unmatched. The turbo four and diesel engine offerings are well worth the extra cost. Jeep has done a masterful job of creating a Wrangler that's both modern and extremely capable. Prices are high and discounts are few, so shop wisely.
