Genesis G80 trim comparison
2025 Genesis G80 2.5T vs 3.5T Sport Prestige
The G80 2.5T starts at $57,100 while the 3.5T Sport Prestige is $77,000. That $19,900 gap buys 8 meaningful differences.
This trim jump changes the engine from 2.5L I4 Turbo to 3.5L V6 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the 2.5T if the 2.5L I4 Turbo already feels sufficient for the way you drive. Step up to the 3.5T Sport Prestige only when the 3.5L V6 Turbo powertrain is the reason you are moving higher in the lineup.
The cleanest way to feel this upgrade is through the payment: about $350/month more over 60 months, or roughly $21,000 extra all-in once interest is included. 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.
