2025 GMC Yukon Specs, Redesign, Dimensions

2025 GMC Yukon Specs, Redesign, Dimensions   –  Go big or go home, as they say – but should you want to do both, a potential choice is in the 2025 GMC Yukon. This body-on-frame family hauler is the largest of the brand’s SUVs and, in its highest trims, also the most luxurious.

The Yukon lineup will get a refresh for 2025, and so the 2025 models are basically unchanged from last year’s offerings. It starts with the SLE at $79,899, including a non-negotiable delivery fee of $2,200. My tester was the opposite end, done up in Denali Ultimate trim, which starts at $129,899. This one was further loaded with $2,590 in options, bringing it to $131,589 before taxes.

2025 GMC Yukon Redesign and Update Plan

Exterior and Interior

The Denali Ultimate isn’t cheap, but it comes with pretty much every Yukon feature as standard equipment. Its options are pretty much limited to gloss-black wheels, extra cameras for towing, and accessories such as floor liners or roof rack crossbars.  2025 GMC Yukon Specs

Its stock items, some standard or optional on other trims, include tri-zone automatic climate control, a multi-colour head-up display, 16-way adjustable front massaging seats, power-folding third-row seats, power-release second-row captain’s chairs, Bose audio with front head restraint speakers, second-row entertainment screens, and camera mirror.

GMC hasn’t stuffed most of the Yukon’s functions into the centre screen – yet – and most are very easy to use. There are buttons and dials for the temperature, seat heating, stereo volume, and drive modes, and even the head-up display functions are handled with simple toggle switches. I’m not keen on the button-style gear selector, but it frees up space on the centre console, which has a generous amount of storage room. The power-sliding console box can be moved ahead to use as an armrest, or slid back to reveal a hidden drawer.

Engine and Performance

There are three engines available across the Yukon lineup, but the base engine, a 5.3L V8 making 355 hp, isn’t used in the Denali trims. Instead, they start with a 6.2L V8, making 420 hp and 460 lb-ft of torque. A 3.0L inline six-cylinder turbodiesel is also available as an extra-charge option on lower trims and no-charge on the Denali. It also makes 460 lb-ft of torque but at lower engine speeds and with better fuel economy.  2025 GMC Yukon Specs

All engines use a 10-speed automatic transmission. The entry SLE and SLT trims are rear- or four-wheel drive, while the AT4 and Denali trims are four-wheel drive-only. The system includes an automatic setting that switches between two- or four-wheel drive as needed for traction. The Yukon’s acceleration with the 6.2L V8 isn’t really what you’d call quick, because there’s a lot of mass it has to move around, but it’s strong and has good highway passing power. However, under light throttle, it can tend to lurch a bit when moving moderately from a stop.

2025 GMC Yukon Fuel Economy

Natural Resources Canada (NRCan) rates the GMC Yukon with the 6.2L V8 at 16.6 L/100 km in the city, 13.0 on the highway, and 15.0 in combined driving; and premium gasoline is recommended although not required. In my week with it, I came in at 15.2 L/100 km.

Opting for a Yukon with the 5.3L V8 brings the combined rating down to 14.0 L/100 km, and the diesel drops that number to 10.5. The Yukon is at the upper end of the scale among full-size competitors, many of which have smaller turbocharged engines. The Ford Expedition uses a turbocharged 3.5L V6 and is rated at 12.9 L/100 combined; the Jeep Wagoneer has a turbocharged inline six-cylinder that’s as low as 12.5 L/100 km; and the Toyota Sequoia, now hybrid-only, rates at 11.7 L/100 km.  2025 GMC Yukon Specs

2025 GMC Yukon Safety Features

Standard driver-assist features on all Yukon trims include emergency front braking with pedestrian detection, automatic high-beam headlights, and teen driver controls. Standard features on the Denali Ultimate – and available on some other trims – are blind-spot monitoring with trailer coverage, emergency rear braking, self-parking, and Super Cruise hands-free highway driving assist.

That last one works on pre-mapped highways, of which there are about 640,000 kilometres’ worth in Canada, although you have to maintain a subscription for it. It can also change lanes by itself, either on-demand when you tap the turn signal, or automatically when it comes up on slower traffic; but you can turn these off if you’d rather do it yourself.  2025 GMC Yukon Specs

2025 GMC Yukon Price and Release Date

At $129,899, the Yukon Denali Ultimate isn’t for the casual sport-utility buyer, but it has some high-end features that aren’t available on the regular Denali, and it isn’t as pricey as the Cadillac Escalade, its mechanical sibling, which tops out at $149,199. Its other sibling, the Chevrolet Tahoe, goes as high as $96,199 (the Suburban is equivalent to the longer Yukon XL).

The Yukon lineup overall runs from $79,899 – that’s for a rear-wheel-drive model – to that Ultimate tag at $129,899. By comparison, the Ford Expedition runs from $77,815 to $106,040; the Jeep Wagoneer is from $92,215 to $95,715; and its more-luxurious Grand Wagoneer sibling goes from $118,415 to $135,895. The Toyota Sequoia tops out at $98,380; the Nissan Armada goes to $83,443; and its Infiniti QX80 sibling’s top trim is $93,595.  2025 GMC Yukon Specs
