The Chevy Tahoe and Chevy Suburban are both full-size SUVs and have been around for many years. But what are the significant differences between the two for the 2025 model year outings, and why would those looking to shop for a three-row SUV at a Chevy dealer near Westland want to buy one over the other? Both options are highly versatile and capable vehicles for all your travel needs around Westland and beyond, but what separates them based on your shopping preferences, and what are the benefits of going for one particular Chevy SUV over the other?
Well, the differences and similarities might surprise you, but both serve distinct purposes within their respective segments. We’ll go over the performance differences, the size differences, and some of the feature differences so you can have an idea of what you’re getting when it comes to shopping for a trim within these particular Chevy SUV lineups. So, right off the bat, let’s start with the differences in powertrain performance and availability.
Powertrain Differences
Both the Chevy Tahoe and Chevy Suburban have the exact same powertrain offerings, but they are configured slightly differently, so between the two full-size SUVs, you get different powertrain ratings. For the latest model year outings, the Tahoe and Suburban feature a 5.3-liter EcoTec3 V8, a 6.2-liter EcoTec3 V8, and for the first time ever, the re-tuned 3.0-liter Duramax turbo-diesel inline 6-cylinder, which is carried over from the very popular Chevy Silverado.
The 5.3-liter EcoTec3 V8 generates 355 hp and 383 lb-ft of torque, while the 3.0-liter Duramax makes 305 hp and 495 lb-ft of torque for both SUVs. All three powertrains are also mated to a 10-speed automatic transmission, so you have smooth shifts and power output during travel. The 6.2-liter EcoTec3 V8, however, has slight differences in performance scaling between the two SUVs.
For the Chevy Suburban, the 6.2-liter EcoTec3 V8 has a base 420 hp and base 460 lb-ft of torque. The Chevy Tahoe has the exact same base ratings for the 6.2-liter V8 as the Suburban, but it also has a performance-tuned version that scales up to 433 hp and 467 lb-ft of torque. This gives you a slight bit of extra gusto out of the Tahoe for those looking for some extra power out of their three-row SUV. The differences aren’t huge, but they do give you an option in how you travel in the SUVs and what you can expect from the top-end performance ratings.
Tow Capacity
The towing capacity for the Chevy Tahoe and Suburban for the 2025 model year are impressive for their sizes, and as full-size SUVs with three rows, they both have trailering capacity above 8,000 lbs. You have a baseline tow capacity of 8,000 lbs for the Chevy Suburban and a baseline tow capacity of 8,200 lbs for the Chevy Tahoe. The Chevy Suburban tops out its max trailering capacity at 8,200 lbs, whereas the Tahoe tops out its max trailering capacity at 8,400 lbs.
Both offer amazing and impressive figures, but the Tahoe edges slightly ahead, and this is because it is slightly smaller and outputs relatively the same amount of power or slightly more than the Suburban, so this enables it to tow just a couple hundred more pounds than the Suburban. However, despite the differences between the two capacities, both SUVs have been given some impressive towing and trailering technologies to help make the process easier when it comes to navigation, safety, and trailer monitoring.
Both are available with a Max Trailering Package featuring an integrated trailer brake controller, Hill Descent Control, Blind Zone Steering Assist with Trailering, and Hitch View. Plus, with the Chevrolet Trailering App, you have access to Trailer Tire Health, mobile trailering app load rating info, Forward Path Indication, Boat Ramp Assist, and Trailer Navigation. So, the differences in towing capacities are minor, but the safety, app support, and trailering packages are exactly the same.

Cargo Capacity
While it might seem like a lot of the advantages fall in favor of the 2025 Tahoe when compared to the 2025 Suburban, it truly is all about what you need from your next vehicle. Both share a lot of similarities but also have their own unique benefits, and that is exemplified quite well when it comes to the Chevy Suburban’s interior cargo capacity. You have significantly more space to work with in the Suburban compared to the Tahoe, and it highlights the difference between Chevy’s two full-size models.
Inside the Suburban, you have a total of 41.5 cu.ft. of cargo capacity behind the third row in the cargo area that you can access from the liftgate. By comparison, the Tahoe has 25.5 cu.ft. of cargo volume behind the third row that you can access via the liftgate. If you fold down the third row, you can access up to 93.8 cu.ft. of cargo volume with the Suburban, whereas in the Tahoe, if you fold down the third row, you can access up to 72.6 cu.ft. of cargo volume. Finally, if you fold down the second row, you can access up to a hugely impressive 144.7 cu.ft. of cargo volume in the Suburban. Inside the Tahoe, you can access up to 122.9 cu.ft. of cargo volume with the second row folded down.
Essentially, you have more space to store more cargo and more passenger room to move about. With the Suburban, you’re looking at nearly 18% more total cargo volume compared to the Tahoe, which is fantastic for those who want a spacious, full-size SUV where you can relax, sit back and stretch your legs. While it comes at the cost of slightly lower towing capacity and lacks the option of the Performance Edition, you can make up for it with the space provided by the Suburban.
Similarities in the Full-Size SUV Segment
Even though the two SUVs may have some notable differences, they also share a lot of the same features, which are bound to be enticing for Westland drivers looking to shop for a large SUV. This includes multiple wheel and color options for those looking to personalize their SUV, as well as robust technology and safety suites that will ensure you are both entertained and kept safe on your way to your destination. Both SUVs feature a large 17.7-inch HD touchscreen as part of the center console stack, but also feature second-row HD touchscreens for passengers in the rear, allowing passengers to watch movies, listen to music, or play games during travel.
Both SUVs also feature a 15-inch head-up display, so you can maintain your focus while driving by keeping your eyes on the road while having telemetry displayed on the windshield in front of you. You also have access to the Super Cruise feature on select trims for both SUVs. This gives you access to hands-free driving spread across hundreds of thousands of miles throughout North America. Even better yet, Super Cruise also comes with built-in trailer support, so you can drive hands-free while you have a cargo trailer attached.
