Used 2018 GMC Yukon for sale 

The 2018 GMC comes in three trim levels: SLE, SLT, and Denali. While the SLT and the Denali seats eight passengers, an optional front bench seat on the SLE trim increase the capacity to nine. Second-row bucket seats are available on the SLT trim and standard on the Denali, reducing the seating capacity to seven. All the three trims are also available in extended wheelbase (which costs an extra $2,700) the Yukon XL which increases the length to 224.4-inch from the standard version which is 203.9-inches long. 

The Yukon SLE and SLT trims get optional 22-inch wheels and a HD Trailering package that adds a unique axle ratio, trailer brake control and a self-levelling suspension. The Yukon's SLT and Denali trims get optional equipment which includes sunroof, adaptive cruise control and a rear seat entertainment system. 

We Recommend

If seating for nine is not a constraint for you, we recommend the SLT trim. The tilt-and-telescoping wheel and power adjustable pedals provide a more comfortable driving position for most buyers. This trim also adds some more features such as power-folding second and third-row seats, a hands-free liftgate along with a proximity key and push-button start.

A 5.3-liter V-8 engine that produces 355-horsepower and 383-pound-feet of torque is standard on the Yukon SLE and SLT.  It comes mated to a six-speed automatic transmission that sends power to the rear wheels or the available four-wheel. The Denali model meanwhile come mated to a 6.2-liter V-8 engine that churns out 420-horsepower and 460-pound-feet of torque. A 10-speed automatic transmission with rear-wheel drive is standard while the four-wheel drive comes optional.

The competition produces more power than the GMC, gains ranging between 20 to 35 horsepower. Torque is the same story, with Ford Expedition pulling ahead with almost 100 pound-feet more than base variant Yukon. The Ford Expedition's power and torque figures also kick in at a lower rpm compared to the other cars. In terms of price to performance ratio, the Expedition makes a strong statement.

Acceleration

Even though acceleration isn't the main criteria for buying a pickup, it's good to have a ride that can pick up the pace if the driver demands so. Even with the truck's huge dimensions, the performance is surprisingly nice. The Yukon covers the 0-60 mph acceleration test in a time of 6.5 seconds. However, the Yukon lags behind when it comes to covering a quarter mile as it takes 16.7 seconds to cover the distance.

All full-size SUVs are known to be gas guzzlers, but this is not the case with the 2018 GMC Yukon as its fuel economy is better than most of its classmates'. The rear-wheel drive Yukon equipped with 5.3-liter V-8 engine returns 16 mpg city, 23 mpg highway and 19 mpg combined. The four-wheel-drive option pushes the figure further down. The Denali trim with its 6.2L engine returns economy figures of 14 mpg city and 23 mpg highway. The Yukon has a tank capacity of 26 gallons.

The Expedition has the best economy figures out of the four cars, but has the smallest tank capacity. The Nissan Armada's fuel economy and the Toyota Sequoia's fuel economy is the lowest among the four cars. Even so, the Toyota has the biggest tank size at 26.4 gallons. The Yukon has the most range, followed by the Ford Expedition. The least range is offered by the Toyota Sequoia.

Even though the GMC is boxy on the outside, the interiors are like the ones found in luxury sedans. The 2018 GMC Yukon's interior is both comfortable and quiet, thanks to its active noise cancellation which works well and isolates the passenger from the outside world. The base suspension manages to get rid of hard impacts, but small bumps in the road may be transmitted to the cabin. The front seats are both heated and ventilated and offer plenty of adjustability along with good support. You also get a good view of the road from front and sides as the windshield pillars are thin. The materials used on the inside are of high quality, and fit and finish is top-notch. The cabin's dash is laid out in a very symmetric fashion. The buttons are firm and not seem cheap. The Denali is pampered well with better leather, fake wood trims and more stitched surfaces.

The Yukon comes with standard seating for eight, but capacity increases to nine with the optional front bench seat and reduces to seven with the second-row captain’s chair. There is plenty of space to stretch out in the first two rows while the third-row seats in the standard wheelbase Yukon is a bit tight for adults. However, the Yukon XL with an extended-wheelbase takes care of the issue as it adds about 10-inches of legroom to the third row.

Here, the Ford shines again. Expedition wins this category too, with class leading front and rear space. Others aren't too far behind too, and none of the cars here will feel cramped, even for a well-built gentleman.

Cargo Space

Cargo capacity varies depending on the body style. Standard 2018 GMC Yukon offers 15.3 cubic feet of cargo space behind third-row, 51.7 cubic feet behind second-row and 94.7 cubic feet with them folded. These numbers are not impressive for a full-size SUV and most of the competitors offers far better cargo capacity than the Yukon.
