2015 Jeep Grand Cherokee Review

For 2015, the Jeep Grand Cherokee lineup sees a minor shuffling of features while the high-performance SRT trim level gets a boost in engine output. The Summit trim level is quieter this year thanks to new noise-cancelling methods.

If you want a midsize SUV that does a little of everything, the 2015 Jeep Grand Cherokee is the way to go. Its well-trimmed cabin is comfy for five, and it's one of the few remaining utility vehicles that can handle both off-road trails and daily commutes.

Four years ago, a complete redesign saw Jeep's senior SUV take a big trip uptown with major improvements in overall comfort, interior quality and styling. Adding an eight-speed automatic transmission and a fuel-saving diesel engine option last year further boosted the appeal of what had already become one of our favorite midsize SUVs. That's still true for the 2015 Jeep Grand Cherokee, which sees just minor changes to its feature content.

The Grand Cherokee's availability of diesel power gives it a sizable fuel economy advantage over nearly every one of its rivals. And you won't be sacrificing much in the way of performance either, as its tidal wave of low-end torque means you've got plenty of muscle for towing or venturing off road. The downsides are that the diesel engine is more expensive than the JGC's gasoline V8 engine (our math tells us that difference is made up at the pump in about 35,000 miles) and that the vehicle doesn't seem to ride and handle quite as well with the diesel.

Given that the current-generation Jeep Grand Cherokee is notably more comfortable and civilized in daily driving than older versions, one might naturally assume that this SUV with a long-standing reputation for off-road prowess has gone soft. Worry not, outdoor recreation and sports fans, as the 2015 Grand Cherokee still has plenty of cred. Jeep offers a few different four-wheel-drive systems to choose from, and there's even an optional off-road package that features an adjustable air suspension that allows you to change the ride height from 6.6 inches for easy entry into low-clearance garages to 11.3 inches for maximum ground clearance while tackling rough terrain. If it's towing you're interested in, the JGC has you covered with the diesel or V8 engines and an impressive towing capacity of more than 7,000 pounds.

Tally it all up and you're left with one of the best picks for a do-everything midsize SUV. The Grand Cherokee's closest competitor, the Toyota 4Runner, shares the Jeep's off-road aptitude, but it doesn't offer a V8 or diesel option, and its interior simply isn't as nice. The price tag on the JGC, however, typically exceeds that of the 4Runner or popular three-row crossover SUVs like the Ford Explorer or Hyundai Santa Fe. In that sense, the Grand Cherokee is similar to the Volkswagen Touareg, which also has a classy, well-trimmed interior and the availability of a diesel engine. The VW is tuned more for on-road performance rather than off-road pursuits, however. Yes, the 2015 Jeep Grand Cherokee will likely cost you more than other midsize SUVs you may be considering, but given its welcoming cabin and wide-ranging strengths, we're fairly certain that you won't mind paying a little more for it.

Every 2015 Jeep Grand Cherokee except for the SRT version comes standard with a 3.6-liter V6 with 290 horsepower and 260 pound-feet of torque. This is the only engine you can get on the Laredos, while the Limited, Overland and Summit models offer two additional engines: a 5.7-liter V8 (360 hp and 390 lb-ft) and a turbocharged 3.0-liter diesel V6 (240 hp and 420 lb-ft). The SRT comes exclusively with a 6.4-liter V8 that produces 475 hp and 470 lb-ft. An eight-speed automatic transmission is standard across the board.

Non-SRT Grand Cherokees offer three available 4WD systems: the single-speed, light-duty Quadra-Trac I system (for the Laredos), Quadra-Trac II with a two-speed transfer case (optional on the Laredo E, standard on Limited and Overland) and Quadra-Drive II with a rear electronic limited-slip differential (optional on Limited and Overland, standard on Summit). An adaptive air suspension (Quadra-Lift) and a driver-selectable traction control system that adjusts to different terrain are also available (optional on the 4WD Limited, standard on 4WD Overland and Summit). The Grand Cherokee SRT features a specialized all-wheel-drive system tuned more for high-performance driving than off-road use.

Equipped with the standard 3.6-liter V6, the Grand Cherokee has EPA fuel economy ratings of 19 mpg combined (17 city/24 highway) with four-wheel drive and 20 mpg combined (17/25) with rear-wheel drive (2WD). At the test track, a Grand Cherokee Overland V6 with 4WD sprinted from zero to 60 mph in a fairly quick 7.9 seconds. Maximum towing capacity for a properly equipped V6 Grand Cherokee is 6,200 pounds.

Jeep Grand Cherokees equipped with the optional 5.7-liter V8 get an estimated 16 mpg combined (14 city/20 highway) with 4WD and 17 mpg combined (14/22) with 2WD. Towing capacity for Grand Cherokees with the 5.7-liter V8 tops out at 7,400 pounds. Fuel economy is vastly improved when you select the diesel V6 engine, which is EPA-rated at 24 mpg combined (21 city/28 city) with 4WD and 25 mpg combined (22/30) with rear-wheel drive. Impressively, the towing capacity with the diesel is the same as the 5.7-liter V8. During Edmunds testing, a Jeep Grand Cherokee 4WD with the diesel engine sprinted from zero to 60 mph in 7.7 seconds.

The 2015 Grand Cherokee SRT returns an estimated 15 mpg combined (13 city/19 highway), while its towing capacity stands at 7,200 pounds.

The 2015 Jeep Grand Cherokee comes with antilock disc brakes, stability and traction control, hill ascent control, hill descent control (optional on Laredo) front side airbags, side curtain airbags and active front head restraints. The Advanced Technology Group (optional on the Limited and standard on Overland, Summit and SRT) includes forward collision warning (with crash mitigation), blind spot monitoring, rear cross-path detection and lane departure warning. Upper trims also come with a rearview camera and park assist features.

In Edmunds brake testing, a diesel 4WD Jeep Grand Cherokee stopped from 60 mph in 121 feet, a respectable distance for this class, while a 4WD Grand Cherokee with the gasoline V6 needed 133 feet, which is longer than average. Meanwhile, the last SRT model we tested stopped in 109 feet, a very short distance but about what we'd expect of a high-performance SUV fitted with summer performance tires and high-performance Brembo brakes.

In government crash tests, the 4WD Grand Cherokee earned five stars (out of a possible five) for overall crash protection, and the 2WD version earned an overall rating of four stars. Both rated five stars for total frontal crash protection and five stars for total side crash protection. The reason for the one-star difference in overall rating is the 2WD version's slightly lower rollover rating.

In testing by the Insurance Institute for Highway Safety, the Jeep Grand Cherokee received the highest possible rating of "Good" in the moderate-overlap frontal-offset, side-impact and roof-strength crash tests. It earned a second-lowest "Marginal" rating in the small-overlap frontal-offset test. The Grand Cherokee's seat/head restraint design was rated "Good" for whiplash protection in rear impacts.

Even when equipped with the base gasoline V6 engine, the 2015 Jeep Grand Cherokee is plenty powerful. It also provides a quiet, comfortable ride and commendable stability around turns. The eight-speed automatic transmission is a great ally, as it makes good use of the V6's power and shifts very smoothly to boot. All in all, most shoppers should be quite satisfied with the base-engine Grand Cherokee.

If you're looking for better fuel economy, though, the diesel-powered V6 is an interesting option to consider. Plus, the diesel's high torque output makes it ideal for big-league towing jobs and off-road use. Around town, the diesel V6 can sometimes lurch in stop-and-go traffic, and it clatters quite a bit. But once it's up to speed, it's exceptionally quiet. Perhaps the biggest downside of the diesel is the sheer weight of this heavy-duty engine; diesel Grand Cherokees weigh considerably more than other versions. This added heft over the front wheels has a negative impact on the way the Jeep steers and handles -- it simply doesn't feel as precise or balanced when going around turns. In addition, our diesel Grand Cherokee test vehicle, which was equipped with the optional Quadra-Lift air suspension, wasn't especially comfortable or smooth-riding on rough city streets (though it showed good composure over larger bumps and ruts on the highway).

If fuel economy is not of particular concern, the 2015 Jeep Grand Cherokee SRT is a tower of power that accelerates and stops at rates that will impress even the most seasoned sports car driver. It's a sleeper performance vehicle if ever there was one, though its run-flat summer tires and aggressive suspension tuning result in a fairly stiff ride on city streets and highways alike.

Off-road, the Jeep Grand Cherokee is at the top of the mountain for its class. Trail obstacles and steep hills are easily dealt with regardless of which engine you choose (although the SRT version is built primarily for paved-road driving), thanks to the advanced four-wheel-drive systems and the Jeep's generous ground clearance.

Even in the lower trim levels, the Grand Cherokee's interior boasts excellent fit and finish. The dash houses a standard configurable 7-inch screen that can be used to display a wide range of information. We're especially fond of the optional center 8.4-inch touchscreen and highly recommend it. It features an easy-to-use interface and includes a WiFi hotspot and smartphone app integration (including media apps from Pandora and iHeartRadio). It also houses the navigation system if the vehicle is so equipped. Sometimes it takes a few too many touch inputs to make climate control adjustments through the touchscreen, but apart from that minor complaint, the Grand Cherokee has one of the most user-friendly cabins in this class.

While the Grand Cherokee has no third-row seat option, there's ample room for a family of four or five, and you can order up a significant amount of luxury ambience, including ventilated front seats and a dual-screen, Blu-ray-capable rear entertainment system with an HDMI input. Backseat passengers should be pretty comfortable, as the Grand Cherokee provides considerably more rear legroom than the Toyota 4Runner. With the rear seats in place, the cargo bay measures 36.3 cubic feet. With the rear seats folded down, the Jeep has 68.3 cubic feet of cargo capacity.
