Chevrolet Silverado 1500 trim comparison
2025 Chevrolet Silverado 1500 LT Fleet vs ZR2
The Silverado 1500 LT Fleet starts at $50,200 while the ZR2 is $70,000. That $19,800 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.7L I4 Turbo to 3.0L I6 diesel Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the LT Fleet if the 2.7L I4 Turbo already feels sufficient for the way you drive. Step up to the ZR2 only when the 3.0L I6 diesel Turbo powertrain is the reason you are moving higher in the lineup.
If you are budgeting this move monthly, the jump from the LT Fleet to the ZR2 is about $349/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $20,940 more by the time interest is counted. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
