Chevy just unveiled the new 2025 model year versions of its iconic full-size SUVs, the Tahoe and Suburban. Now, notice we didn’t say “all-new” —this a mid-cycle refresh, so the changes didn’t meet the generous threshold the industry uses to claim something is worthy of that title. But the new models still include some exciting additions to help the Tahoe and Suburban feel a little more premium and a little less like a step down from their GMC Yukon and Cadillac Escalade siblings.
Here’s what you need to know about the 2025 Chevrolet Tahoe and Suburban.
The Tahoe and Suburban pick up a better diesel engine

The 2025 Tahoe and Suburban can be fitted with a new second-generation 3.0-liter Duramax inline-six turbodiesel. It gets a bump up to 305 horsepower from 277, and to 495 lb-ft of torque from 460. It upgrades to a 10-speed automatic transmission, too. And for the first time, it will be available as an option for all trims, including the Z71 off-road version. The diesel will be available in calendar year 2025, after the initial launch.
Of course, the tried and true 5.3-liter and 6.2-liter V8 gas engines are also available.
