2020 GMC Yukon Performance

GMC Yukon Performance Rating

2020 Yukon Performance

It goes without saying that a large SUV such as the Yukon requires a reasonably large amount of power to pull its considerable weight around town, and what is the easiest way to accomplish that? By fitting a V8 engine under the hood, of course. In base trim, the Yukon belts out an adequate 355 hp and 383 lb-ft of torque, which is enough to happily lug around this large SUV. In town, there's enough low-down torque to pull the Yukon around with convincing pace, and out on the highway, the base engine will happily cruise along at illegal speeds. For those who like the idea of a large SUV, but want the go of smaller performance cars, the 6.2-liter V8 engine is a must with its 420 hp and 460 lb-ft. It pulls the Yukon with anger and feels rapid, although 0-60 sprint times will never be its main objective. With the HD trailering package equipped, the 5.3-liter V8 Yukon will tow a maximum of 8,500 lbs. Impressive stuff.

Engine and Transmission

There's no replacement for displacement, especially when it comes to hauling heavy metal units such as the 2020 GMC Yukon. Instead of going with smaller capacity turbo engines such as the 2.3-liter turbocharged inline four-cylinder engine found under the hood of the Ford Explorer, which produces 300 hp, or the more powerful 3.0-liter twin-turbo V6 producing 400 hp, GMC has stuck with a set of naturally-aspirated V8 engines that get the job done reliably. The base engine is a 5.3-liter V8 producing 355 hp and 383 lb-ft of torque. This engine offers ample pulling power and should suit most needs, especially for those who do most of their driving in town. If it's more power you're after, GMC offers a Corvette-sourced 6.2-liter V8 engine producing 420 hp and 460 lb-ft of torque. This engine gives the Yukon some serious attitude, and it feels quick, to say the least. 5.3-liter cars come equipped with a smooth-shifting six-speed auto, while 6.2-liter cars get a ten-speed auto. All Yukon SUVs get a limited-slip differential as standard, as well as Tow/Haul transmission modes for pulling heavy stuff.

2020 Yukon Gas Mileage

Getting close to 40 mpg from gas-powered cars isn't that shocking anymore, and with the help of hybrid electric systems, those numbers are being pushed ever further. Some manufacturers have introduced such fuel-saving measures in their offerings, but if you're looking for fuel economy, you're not going to find it here. The EPA rates that the Yukon will do a best of 15/22/18 mpg city/highway/combined in 2WD 5.3-liter guise. That's not an impressive gas mileage figure by any stretch of the imagination. The significantly more powerful 6.2-liter version, also in 2WD guise, will do 14/23/17 mpg. That's not a bad compromise for all that extra power. 4WD variants lost one mpg on highway and combined cycles. With a 26-gallon fuel tank, the 2020 GMC Yukon will be able to travel between 442 and 468 miles on a single fill-up. The 5.3-liter V8 can run on E85, but this sees the consumption rate dip dramatically, and you should see a maximum range of only 338 miles.
