2025 Chevrolet Tahoe Z71 and Suburban Z71 will offer updated diesel
New design and repackaged components make room for the oil-burner
Chevrolet added a diesel option to the new-generation 2021 Tahoe and 2021 Suburban, the first time the full-sizers had the option of an oil-burner since 1999. Chevy's chief engineer for the SUVs told Autoblog at the time, "It really came down to us giving customers a lot of choices. We know the SUV buyer is looking for this opportunity." Not long after the debut, we learned the Z71 wouldn't offer the turbocharged 3.0-liter inline-six Duramax diesel. Available as an option on every other trim, the Z71-specific front fascia designed to improve the SUVs' approach angles interfered with the oil-burner's intercooler and plumbing. That remains the case with the 2024 Tahoe and Suburban, and in the automaker's press release for the refreshed 2025 SUV siblings, we got info about the upgraded diesel but nothing about a trim expansion. All the automaker had to say was, "The new diesel engine will be available in 2025 after initial launch." GM Authority spoke to a Chevy exec who confirmed that whenever the diesel is open to order, the Tahoe Z71 and Suburban Z71 will offer it.
