The 2025 Suburban gives you options. I drove the 5.3-liter V8 and it felt rock-solid—strong on the highway, smooth in town, and ready to tow with ease. I took it out on a long stretch of I-90 and was impressed by how effortlessly it picked up speed. Chevy also offers a 6.2-liter V8 for even more muscle, and a 3.0-liter Duramax diesel for those long-haul types who want serious torque and range.
- 5.3L V8: 355 hp / 383 lb-ft of torque
- 6.2L V8: 420 hp / 460 lb-ft of torque
