Volvo XC90 trim comparison
2026 Volvo XC90 B5 Ultra vs B6 Ultra Dark
The XC90 B5 Ultra starts at $70,150 while the B6 Ultra Dark is $73,350. That $3,200 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.0L I4 mild-hybrid Turbo to 2.0L I4 mild-hybrid. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the B5 Ultra if the 2.0L I4 mild-hybrid Turbo already feels sufficient for the way you drive. Step up to the B6 Ultra Dark only when the 2.0L I4 mild-hybrid powertrain is the reason you are moving higher in the lineup.

The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
