The 2025 GMC 3500 is a heavy-duty pickup truck that is expected to be released in late 2024. It is part of the fifth generation of GMC 3500 trucks, and it is expected to receive a number of updates and improvements over the current model. One of the most significant changes to the 2025 GMC 3500 is the addition of a new 3.0-liter Duramax turbo-diesel engine. This engine is expected to produce more power and torque than the current 6.6-liter Duramax engine, and it is also expected to be more fuel-efficient. In addition to the new engine, the 2025 GMC 3500 is also expected to receive a number of other updates, including a new 10-speed automatic transmission, a new interior, and a new exterior design.
