2021 GMC Yukon XL Denali SUV Features

Before 2021, the Yukon XL used to have three trim options on their list. But, this year a new trim debuted namely AT4 which is just placed below the topmost trim i.e Denali to serve the mid-range buyers. So, with this new addition, the total number of trims got increased to 4 and the name of base trim is SLE followed by SLT, AT4, and Denali.

Every trim compared to their price range houses a justifiable amount of features. Although, the Denali being the topmost trim consists of multiple luxurious and standout features. The Yukon XL Denali has a big 6.2L V8 engine and the capacity of which is better than any other trims. 

Moreover, it has got the best possible features in every class that is unique to Denali trim only. Those features include Bose 14-speaker premium sound system, a 15.0-inch head-up display, HD surround vision camera, integrated Navigation system, and power-release second-row bucket seats.

Which trim should you buy?

The trim choice would completely depend upon the buyer according to his needs and budget. The SLE trim seems a valuable model at a much lower cost but the Denali coming at a higher cost has better engine, performance, and most importantly a ton of standard as well as optional features. 

So, overall the SLE trim looks very good and super-valuable in its price range. But, if you are ready to spend more to feed your cravings for more power & luxury then you should shift towards Denali.

Since Yukon and Suburban come from the same manufacturer i.e GM, we can see pretty much similar specs in both of them. The price of Suburban is higher than Yukon in this class but it is also the quickest in its class so it gets justified. The Expedition here comes with the highest price tag but its feature tends to fall short in front of the other rivals.

How well does the 2021 GMC Yukon XL Denali handle?

Being a big and heavy-duty SUV, people may get caught up with negative perceptions when it comes to riding quality and handling. But, GMC with its new generation 2021 GMC Yukon XL focused on this aspect and the results came out to be amazing. 

The steering of this car feels light and the steering feedback also got quicker and better. The inclusion of a new independent rear suspension also improved this SUV’s performance on tough roads. Although, for better off-roading, a dedicated AT4 trim has been introduced this year Denali’s performance remains average here. 

The bulky size of this SUV may create a little uneasiness while passing through a crowded place or while parking which was expected looking at its size. There is also an available AWD model which costs around $ 3,000 more but with this expense, you get a much better grip and stability while cornering.

Braking Performance

The braking performance of this SUV got a lot better this year in comparison to its predecessor. The big Duralife 13.6-inch rotors work precisely and make the vehicle stop faster than before.

These rotors are fully engineered to perform for heavy-duty trucks or SUVs like Yukon. Apart from that, the availability of ABS and features like automatic emergency braking also helps the vehicle in certain conditions to come to a stop quickly whenever needed.

The brake rotors of Denali and Suburbans are very big in size than other rivals. But, when it comes to stopping power from 60-0 then GMC completes it in 125 feet whereas the Suburban and Expedition makes it within 121 feet which is good.The Toyota is the heaviest car amongst the list and that gives it a big disadvantage having to go farthest before stopping.

2021 GMC Yukon XL Denali SUV Fuel Economy

The MPG figures of the 2021 GMC Yukon XL are the same as the Yukon but the only notable change is its fuel tank capacity which is a little higher. The MPG figures of this SUV are good but some of its closest rivals give a much better economy. 

The base models of the Yukon provide a little better range because of its 5.3L engine but the Denali on the other hand comes with more power.

Here, the Expedition has the highest fuel MPG with the biggest fuel tank which ultimately leads to a very long-range output, all thanks to its V6 engine which is known for saving some bucks on gas. The Yukon along with its twin brother Suburban also performed well but Yukon seems to have a slight upper hand.

The Yukon and Suburban, both coming from the same carmaker, share the same interior as well as cargo dimensions. They both completely dominate in the front, rear & cargo spacing but the Ford Expedition here beats them in the third row. The Land Cruiser because of its short wheelbase struggled to manage better spacing inside like its competitors.

2021 GMC Yukon XL Denali SUV Final Verdict
