2026 Genesis G80 2.5T Sport Prestige vs 3.5T Prestige Black
The G80 2.5T Sport Prestige starts at $69,950 while the 3.5T Prestige Black is $79,350. That $9,400 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 Sport Prestige if the 2.5L I4 Turbo already feels sufficient for the way you drive. Step up to the 3.5T Prestige Black 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 $165/month more over 60 months, or roughly $9,900 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.
