2018 GMC Yukon

A moderately more upscale version of the Chevrolet Tahoe, the GMC Yukon is a full-size SUV with traditional body-on-frame construction that makes it an excellent towing vehicle. The Yukon, along with its extended-length Yukon XL sibling, was recently redesigned, resulting in a better-trimmed cabin and more technology features. The Denali variant approaches Cadillac levels of luxury.

Recent changes

For the most recent model year, the Yukon received only a small handful of enhancements. The most significant is a new transmission exclusive to the Denali model.


It's most definitely an old-school, pickup-based utility vehicle that doesn't falter at the prospect of traversing a torturous trail or towing a heavy boat, but the Yukon is also up to the task of serving as a cushy people and cargo hauler.

As with previous Yukons, interior acreage for passengers in the first two rows of seats is ample, and there's 51.3 cubic feet of stowage space behind the second row. A full 94.7 cubic feet are available with the second row folded down. Unfortunately, things still get less rosy when the third row - which now folds flat into the floor - is pulled up into place, with cargo capacity falling to 15.3 cubes. Furthermore, due to the Yukon's rugged but bulky solid rear axle, the seats provide only enough space to comfortably seat children.

However, unlike its predecessors, the latest Yukon's cabin features an attractive, swept-back dashboard and upscale materials like metallic-appearance trim and available perforated leather upholstery. Futhermore, all Yukons are equipped with GMC's IntelliLink infotainment system, which integrates entertainment and navigation functions (when equipped), and also offers access to smartphone-based apps like Pandora radio and Stitcher radio.

The system can be controlled through dashboard knobs, steering wheel buttons or an eight-inch touchscreen (which motors up to reveal a hidden storage compartment), and there's also a voice recognition system for hands-free calls, destination entering, song selection and more. Its "natural language” functioning can recognize a staggering number of phrases - effectively eliminating the need for the clunky and cumbersome memorized commands.

The Yukon also offers numerous luxury extras, including heated and ventilated front seats, a heated steering wheel, a Bose surround sound stereo and a rear-seat Blue-ray entertainment system. The Yukon Denali ups the ante even further, although its feature content has not yet been announced.

Powertrains, Towing and Fuel Economy

The Yukon comes standard with a pushrod 5.3-liter V8 that produces 355 horsepower and 383 lb-ft of torque. The Yukon Denali utilizes a 6.2-liter V8 with 420 ponies and 450 lb-ft of twist.

Both mills are equipped with direct-injection, variable valve timing and a cylinder deactivation system. The 5.3-liter sends its output to the wheels by way of a six-speed automatic transmission, while the 6.2-liter benefits from a ten-speed automatic unit.

Rear-wheel-drive is standard, while four-wheel-drive is an extra-cost option. RWD models equipped with an available Maximum Trailering Package can tow up to 8,500 lbs.

Although not a dedicated mud-slinger, the Yukon is more than capable of handling light off-roading situations.

RWD Yukons with the 5.3-liter V8 are rated at 16/23 city/highway mpg, while 4WD variants check in at 16/22 mpg. The Yukon Denali returns 15/21 mpg regardless of which configuration is chosen.

The Yukon Denali is equipped with a Magnetic Ride Control real-time damping system, which can adjust the dampers in the blink of an eye to mitigate body roll during hard cornering or keep the ride comfortable while cruising.

Trim Level Breakdown
