Genesis G80 trim comparison
2026 Genesis G80 2.5T vs 3.5T Sport Prestige
The G80 2.5T starts at $58,450 while the 3.5T Sport Prestige is $78,350. 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.
If you would notice the 3.5L V6 Turbo every week, the 3.5T Sport Prestige makes sense. If not, the 2.5T is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
Think about this as a monthly tradeoff, not just a sticker gap. The 3.5T Sport Prestige adds about $351/month on a typical 60-month loan, or around $21,060 more overall with interest. If that different powertrain is not part of your real use case, the cheaper trim keeps more money in your pocket without changing the core experience you need.
