Main Differences Between X31 VS Z71

We have already provided a comparison table above. However, we are aware that there are several more factors that we need to consider when determining the differences between the two. Well, it is time that we develop deeper into it. 


It has to be known that X31s were initially marketed as off-road rear wheel vehicles. However, they are pretty good in all terrains, irrespective of the tracks and texture. 

On the other hand, Z71 is suitable only for off-road. However, you might not want to drive it through hilly tracks if you want to get the best performance from it.

Body Manufacture

If we consider the manufacturing method of the body and frame for these cars, GMC X31 is built in the same way as other cars. It is manufactured from high-pressure point metals that are robust yet light using welding. 

For the Chevrolet Z71, the metal sills were pre-manufactured and then put into place. It is then accompanied by a brushed finish that further alleviates its glorification.  


When it comes to the facilities, they are very similar in what comes inside. However, there are specific points that can still be pointed out. For instance, the X31 has a built-in engine oil cooler which helps increase the rate of power emission compared to the Z71. 

The additional point is that X31 comes together with a technology that integrates with your smartphone. Although the Chevrolet has its own features like rear park assist and notable off-road package deals, it comes off from a far cry for GMC Sierra Denali.

Fuel Consumption

When it comes to fuel economy, the GMC X31 wins the battle. Despite having the same fuel capacity, the Z71 has a more significant CO2 emission. Additionally, GMC’s larger fuel capacity also contributes to making this model have a greater fuel usage efficiency rate. 

Differences Between Chevrolet VS GMC

Now that we have covered two of the models from both GMC and Chevrolet, you might be wondering which one between the two would be able to pack the better offer for you and your limited budget.

Well, that is what we are here for. We have compiled all the factors that you need to take into consideration so that you can find out the best choice between the two by yourself. 


Not many people know about this fact, but General Motors manufactured both Chevrolet and GMC. Chevrolet was separated at birth and became a vessel company to the original GMC. 

While there are several similarities between the two and the fact that they are being made in the same factory, it is the manufacturing method that determines the brand that the manufactured car will take after.


If we consider the price, then Chevrolet is the clear winner between the two. Because of its commercialized manufacturing technique, Chevrolets are far more affordable than GMC motors with a premium build. 

For instance, if we consider the Chevrolet Z27, it has a base price of 30,000 USD. On the other hand, the GMC X31 has a price tag of 53,000 USD. 

Seat Comfort

Both of these brands manufacture their cars in the same factory and use the same detailed and sophisticated engineering to ensure that the seats are as comfortable as possible with ample legroom.

However, Chevrolet might be the winner by a slight margin. It contains genuine leather upholstery in the passenger seats and door handles, whereas the GMC vehicle uses synthetic clothing.

Of course, this isn’t something to be picky about since not many people can detect major detail between the two high country pickup trucks in the first place.

Engine Performance

Both of the brands use gas-type fuels between V6 and V8 ratings, depending on the model. While the input energy and the rate of emission differ, both of them will provide similar results in engine performance. 

Additionally, both brands use the same engine motors, which result in the same horsepower and torque-speed in their model vehicles.

Fuel Economy

While most GMC and Chevrolet vehicles have similar fuel economy and carbon dioxide emission rates. However, a few special GMC vehicles use specialized engine options like the 53l ecotec3 v8 engine to reduce this emission. 

As a result, these GMC X31 package models have lower carbon dioxide and a superior fuel economy than any of Chevrolet vehicles. 

So Which One Is Better Between X31 VS Z71?

Well, there are several aspects of both these models, along with the brand of vehicles that make them, that you will need to understand before making the decision. 

We have already mentioned this earlier, but these cars are made in the same factory. This case is followed to improve certain flaws in the first car in the second car. 

Based on our perception, we believe that Z71 is the better choice between the two since it has a lower price tag.

However, if you can afford X31 in your budget, we advise you to buy the GMC for the GMC Sierra Elevation feature hat makes it far more eco-friendly than any other options with JHD hill descent control. You can check on the owner’s manual for more details
