What does SLT mean on a GMC? In short, SLT is an abbreviation for Special Luxury Trim, and it is a trim level available on SUVs, GMC Trucks, and even some Dodge truck models.

Of course, it’s not a nonsense thing. It includes outstanding features that the standard trim does not have!

What Does SLT Mean On A GMC?

As mentioned above, it means Special Luxury Trim.

The manufacturer created this Standard Luxury Touring option to provide an excellent option for its customers looking for luxury without paying the Denali price tag.

Other extra bells and whistles have come with this trim to improve comfort while on the road.

They also provide additional entertainment features for people to choose from to keep them occupied while driving.

You have got the answer for “What does SLT mean GMC?,” but what makes it stand out?


The SLT is the top-of-the-line trim level with a slew of luxury features. These add-ons are intended to boost the comfort and convenience of your driving experience.

When you pay for this package, it includes heated front seats, leather seats, a navigation system, a remote start, etc.

You’d expect to find these high-end features in a premium car, but they’re now available on a truck.


SLT trucks are also of very high quality. They are built to withstand a lot of abuse. This is because high-quality materials and cutting-edge manufacturing techniques were used.


SLT is appreciated with various features. Moreover, they represent excellent value for money. And you’ll frequently discover that the SLT is less expensive than its rivals.

This is because manufacturers include many features on the SLT that are supposed to be optional extras on other competing models.

SLT Trim Features

One of the reasons that makes it so valuable is the trim. When you spend extra money on something, what you get in return has to be worth the money.

  • Front seats that are heated
  • Premium audio system by Bose

STL And STE: Comparison

Another phrase that you should not ignore when owning GMC vehicles is SLE.

We often confuse the concepts as well as the features between them. Many people don’t even know what they are!

So what does SLE mean on a car?

The GMC SLE meaning is “Special Luxury Edition.” It is a worth-considering choice for drivers looking for a GMC truck that is one step above the base models, with standard amenities in the vehicle’s interior and exterior features.

The SLE is the entry-level trim option available to GMC drivers and is a popular pick for many truck buyers.

This one comes standard with front bucket seats, an 8-inch touchscreen with IntelliLink, and many premium painted aluminum bright machined wheels.

Keep in mind that these options vary depending on the model of your truck. There are many upgraded and optional packages that you can take a glance at.

Some outstanding ones are Driver Alert, SLE Convenience or Chrome Appearance, etc., created to increase your truck’s capabilities for your specific driving needs.

The Similarities

Along with the SLT GMC meaning and SLE GMC meaning, let’s look at the similarities that the SLE and SLT have shared.

Both models feature unique C-shaped LED lighting. For example, we can’t ignore the LED tail lamps, which come with high-intensity headlamps.

The steering wheel in both models is wrapped in leather. Individuals will feel more at ease with this leather.

These two features cover GMC Pro Safety, GMC Connected Navigation, 4G LTE wi-fi, an audio system with six speakers, Amazon Alexa built-in, and GMC Connected Access.

Their front seatback allows an individual to pull items 8 ft long at max.

Simultaneously, the 60/40-split flat-folding rear seat mod is enabled via the release levers, which can be found in the back cargo with ease.

They also developed a function for smartphone users who have Android Auto or Apple CarPlay or want to navigate confidently with smart safety add-ons. It keeps you connected throughout their journey.

Another commonality is that the car models with SLT and SLE are either all-wheel drive (AWD) or front-wheel drive (FWD).

The Differences

Now, let’s learn the difference between SLT and SLE on your GMC vehicles.

First, in terms of price, SLT packages will usually have higher average prices than SLE ones. The main reason is the former has more deluxe features than the latter.

Your SLT package comes standard with heated seats and dual-zone climate control, whereas the SLE is optional.

The technological experience of these two also bear a bit difference, like the display screen size.

The exterior upgrades are another distinction between the two. For example, the 2021 GMC terrain SLT has larger 18-inch aluminum wheels.

You can spot some dark gray accents painted on these wheels. On the other hand, the SLE package has 17-inch silver wheels.

The hands-free programmable liftgate and the typical fog lamps usually appear in the SLT models but not in the SLE.

The two also differ regarding interior upgrades. The 2021 GMC terrain SLT, for instance, has a steering wheel that can be heated and seat trim with perforated leather.

You can benefit from ambient lighting inside the car, an eight-way power driver seat, and a six-way power front passenger seat, as well.

On the other hand, the SLE has premium seats and 4-way annual front seats.

On Specific Models

GMC Acadia

The 2.0L turbocharged in its SLE or SLT trim levels produces 258 lb/ft of torque. The SLT, meanwhile, can be upgraded to a 3.6L V6.

The Acadia SLE delivers a maximum towing capacity of 3,500 lbs with the towing package. The SLT can be up to 4,000 lbs. Both versions are available with a nine-speed automatic transmission for the 2.0L.

There is a heads-up display, HD surround vision, and heated rear seats on Acadia SLT. None of these features is accessible on the GMC SLE.

GMC Sierra 1500

True to the GMC SLT meaning, its features are truly remarkable on the GMC Sierra 1500. The 2021 GMC Acadia SLE comes with a 2.7L turbocharged engine that can be leveled up to a 3.0L I6.

The SLT version, however, has a 5.3L V8 EcoTec3 engine that can be downgraded to a 3.0L I6 or upgraded to a 6.2L V8 EcoTec3.

The SLE boasts a GVWR of 7,000 pounds, while that of the SLT is 7,100 pounds.

Both can be tuned to a maximum weight of 7,300 pounds. An integrated ProGrade Trailering System and trailer brake controller are both standard in your SLT package.

This provides HD surround vision and makes driving with a trailer easier.

GMC Sierra 2500HD

Both trim levels use a six-speed heavy-duty automatic transmission and can be upgraded to a ten-speed automatic transmission.

It comes with a Prograde Trailering System and an HD Rear Vision Camera, whereas the SLE package does not include these options.

The HD Surround Vision and Digital Variable Steering Assist are also the exclusive features of SLT, which are absent in the SLE package.

GMC Sierra 3500HD

Both SLT and SLE use an automatic transmission which is six-speed and heavy-duty, but only models with SLE can be pushed to a ten-speed automatic transmission.

Both share a maximum GVWR of 11,350 pounds, which you can boost to 12,100 pounds.

Still, only the SLT brings you an HD rear vision camera and autotrac two-speed transfer case, while the SLE has it as an optional feature.

Better yet, the Digital Variable Steering Assist is exclusive to the SLT, not on the SLE.

GMC Terrain

Drivers can find fog lamps, heated mirrors with indicators, and a programmable liftgate on the SLT. The SLE, on the other hand, does not have a liftgate and fog lights.

Going inside, the SLT’s adjustment options for passenger and driver seats are far more extensive than those of the SLE.

Heated front and rear seats are standard on the SLT, and these ones are optional on SLE. The best part is that you can enjoy heated steering wheels on SLE but SLT only.

GMC Yukon

A 3.0L Duramax Turbo-Diesel engine is available in both packages. These engines are linked to an automatic transmission with 10-speed in both cases.

The Yukon SLT offers HD Surround Vision,  GMC Pro Safety Plus, ventilated and heated front seats, and second-row outboard seats, while the SLE lacks these.


Do All SLT Vehicles Have The Same Features?

No, they don’t.

Because each model will be different in design and features, the SLT packages will also be varied to fit your vehicle. The difference here can be the automatic transmission, seat features, etc.

Is SLT Or SLE Better?

Should you choose the SLE or SLT packages? The answer depends on your needs and budget.

If you like a car with a powerful engine and many premium features and don’t mind the cost, the SLT is for you.

In contrast, the SLE package is a cost-saving option when you only need to upgrade some important details and features.

What Is Included In SLT Package?
