The good: Respectable fuel economy for a heavy-duty off-roader, control layout

The not so good: Hard-to-access cargo area (soft top), intrusive engine stop/start feature, options (some of which you’d expect to be standard equipment) really drive up bottom-line price

CG Says:

Way back in its Willys days, the Jeep CJ did folks who needed—or wanted—to drive far off the beaten path a favor just by being around. Today, in its FCA days, the Jeep Wrangler does like-minded folks a favor by adding a turbodiesel engine option for 2020.

A small badge underneath the driver’s-side taillight indicates the presence of the new-for-2020 Wrangler EcoDiesel engine.

The beauty of the 3.0-liter V6 built in Italy by VM Motori is its torque. The 442 lb-ft of twist is far and away the most provided by any of the three engines available in a Wrangler. That’s a handy commodity to have when plowing through sand or picking out a path over rocks, as was borne out in Consumer Guide’s First Spin report on the Wrangler EcoDiesel. It also doesn’t hurt that the diesel is frugal with fuel, which translates into impressive driving range.

Test Drive: 2020 Jeep Gladiator Mojave

In Sahara trim, the Jeep Wrangler Unlimited has a pleasantly upscale cabin for a rugged off-roader–particularly when outfitted with the leather interior upgrades and the Cold Weather Group, which adds heated front seats and steering wheel.

However, CG’s subsequent test of an EcoDiesel Wrangler—the subject of this report—was carried out on urban streets and expressways. In that setting, the diesel V6 still operates well, but with the advantages it brings to off-road driving not demanded of it in traffic, the value of this $4000 option is somewhat blunted.

Push away from a full stop with some intent and the tachometer sweeps up to around 2500 rpm (and an accompanying upshift from the required 8-speed automatic transmission) before the engine feels like it‘s fully flexing all its muscle. That kind of controlled force will perform good service in places where the term “road” does not apply. Back home on the street where you live, however, it might come across as a little sluggish.

The Wrangler Unlimited’s rear-seat area is spacious enough for average-sized adults to ride in comfort, though the door openings arenarrow and step-in is high. Power-window switches and charging ports are located on the center console.

At the point where the 260-horsepower turbodiesel V6 does feel like it’s coming into its own, it is by then squarely in the best part of its torque band, and performs with authority. There’s little of the clatter usually associated with diesel engines—which has been true of the EcoDiesel since it first entered FCA’s orbit in 2014 for use in Ram 1500 pickups—and beefed-up insulation methods help keep things that way. Engine stop/start is rocky and noisy at engagement, and we could hardly wait to turn it off. The EPA projects that a turbodiesel Wrangler will average 22 mpg in city driving, 29 on the highway, and 25 combined—all considerably better than the standard gasoline V6. With a little more than half their driving in city conditions, CG testers slightly surpassed 23 mpg.

The Wrangler’s unusual swing-out tailgate can be tricky to use in tight quarters, and the soft top’s vinyl rear window isn’t hinged; it has to be removed completely, which is a multi-step process. There’s some handy storage space underneath the cargo floor, which includes holes for storing the hardware from the Wrangler’s detachable doors.

The turbodiesel option can only be had in four-door Wrangler Unlimited models, and even then it is restricted to seven of the 12 available versions. CG sampled it in a Sahara that starts at $40,140 with delivery, but spiked to $55,925 with copious extras. The powerplant is actually part of a package that includes a smaller 18.3-gallon fuel tank, Dana M210 front axle, antispin rear differential with a 3.73:1 axle ratio (replacing the standard 3.45 gears), and 255/70R18 all-terrain tires (in place of all-season rubber). The less-street-friendly tires negate some of the ride improvement we’ve praised in the current Wrangler generation that dates to 2018.

Choosing the 3.0-liter turbodiesel V6 engine adds a hefty $4000 to the sticker price, but that also brings 18-inch all-terrain tires, an anti-spin rear axle, 18.3-gallon fuel tank, Dana M210 front axle, and a 3.73 rear-axle ratio.

As we tested gas-engine Saharas from 2018 and 2019, we’ll refer you to those reviews for our evaluation of features and accommodations, none of which are fundamentally altered for ’20. Our turbodiesel tester maintained the standard-equipment Command-Trac part-time four-wheel-drive system, but got much plusher and tech savvy with its many options. Leather draped the seats (with Sahara-logo headrests), steering wheel, shift knob, and parking-brake handle; front seats and steering wheel were heated. Full LED lighting and the choice of two tops—soft Sunrider or hard 3-piece cap—were visible from the outside. The Premium Audio Group added the Uconnect 4C with GPS navigation, 8.4-inch touchscreen, and Wi-Fi hotspot, while a couple of safety packages brought in things like blind-spot and rear cross-traffic alerts, adaptive cruise control with stop function, and full-speed forward-collision warning.

The new turbodiesel V6 might not be the perfect choice for every Jeep Wrangler buyer. However, having it in the mix will definitely help many of them better tailor a Wrangler to their needs.

The addition of a turbodiesel engine for 2020 gives the Jeep Wrangler an attractive new powerplant choice for some shoppers–and a plug-in hybrid Wrangler is slated to follow in the near future.
