2024 Chevy Duramax Diesel Review. The 2024 chevy silverado zr2’s duramax diesel engine has proven efficient, but we weren’t ready for its astonishing best tank of 34 mpg with 826 miles of range! Ranking the 5.3l ecotec3 v8 and 3.0l duramax turbo diesel engines against one another is a rather tricky proposition because they both serve different applications, even if they are typically.

On the zr2, the duramax is an additional $9,490 but is money well spent. In isolation, the engine is a monster.
