The Chevy Tahoe has become an icon in the traditional SUV space. Having made its debut in 1994, it’s now been on the market for more than three decades. When it was first offered all those years ago, it was available with a diesel engine, but unfortunately for enthusiasts it was taken away when the Tahoe entered its second generation at the turn of the century in 2000. It wasn’t until the Tahoe entered its fifth generation just a few years ago in 2021 that a diesel engine would finally be offered again, thanks to the 3.0L Duramax Turbo Diesel I6 engine.
Now, the 2025 Chevy Tahoe is available, and the Duramax diesel remains a strong option available on almost every trim level – including the off-road focused Z71 trim for the first time ever. Only the base LS trim level is unavailable with the offering. So, with that in mind, we thought you might be interested to learn more about the fuel economy ratings – or MPG – and tow ratings that this incredible full-size SUV and diesel engine combination has to offer.
Duramax Diesel Power & Performance
Before we dive into the efficiency and towing capabilities of the 2025 Chevy Tahoe, let’s highlight the actual specifications of the 3.0L Duramax Turbo Diesel I6 engine that we’re discussing today. Here are some of the important bit of information regarding the powertrain and its performance:
- 277 horsepower
- 495 pound-feet of torque
- 10-speed automatic transmission
- Available in both 2WD and 4WD configurations
Whether you’re packing the family in for a road trip, using this behemoth as a daily driver or even tackling nearby off-road trails, the 2025 Tahoe has plenty of power to get the job done and deliver an enjoyable experience behind the wheel.
Fuel Economy Comparison
One of the main reasons that the market took such a sharp turn away from traditional SUVs towards their crossover counterparts was fuel economy. In terms of both environmental and bank account protection, people didn’t want gas guzzlers anymore. But they still had plenty of attractive features, which is why a few stalwart SUVs like the Tahoe remain popular today. Still, wouldn’t it be nice if you did have a more efficient option? That’s where diesel comes into play. Check out the following table to see how the Duramax engine compares to the other available engine options in terms of fuel economy.
| Engine | City MPG | Highway MPG | Combined MPG |
| 5.3L V8 | 15 | 20 | 17 |
| 6.2L V8 | 14 | 20 | 16 |
| 30L Duramax Diesel | 21 | 28 | 24 |
Maximum Towing Capacity
While a lot of people immediately look to pickup trucks when they imagine towing, a lot of SUVs are quite capable of hauling your boat or snowmobiles too. While the 6.2L and 5.3L V8 engines can trailer 100 and 200 pounds more than the 3.0L I6 can, respectively, the Duramax Turbo Diesel still offers an impressive and handy 8,200 lbs. of maximum towing capacity when equipped with the Max Trailering Package, which also includes the following features:
- Blind Zone Steering Assist with Trailering
- Enhanced Cooling Radiator
- Hitch View
- Integrated trailer brake controller
- Smart Trailer Integration Indicator
