Buick Encore GX trim comparison
2026 Buick Encore GX Preferred vs Avenir
The Encore GX Preferred starts at $25,900 while the Avenir is $31,400. That $5,500 gap buys 5 meaningful differences.
This trim jump changes the engine from 1.2L I3 Turbo to 1.3L I3 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the Preferred if the 1.2L I3 Turbo already feels sufficient for the way you drive. Step up to the Avenir only when the 1.3L I3 Turbo powertrain is the reason you are moving higher in the lineup.
If you are budgeting this move monthly, the jump from the Preferred to the Avenir is about $97/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $5,820 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.
