Volvo XC90 trim comparison
2025 Volvo XC90 B6 Plus vs B5 Ultra
The XC90 B6 Plus starts at $64,300 while the B5 Ultra is $66,300. That $2,000 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.0L I4 mild-hybrid to 2.0L I4 mild-hybrid Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the B6 Plus if the 2.0L I4 mild-hybrid already feels sufficient for the way you drive. Step up to the B5 Ultra only when the 2.0L I4 mild-hybrid Turbo powertrain is the reason you are moving higher in the lineup.
Think about this as a monthly tradeoff, not just a sticker gap. The B5 Ultra adds about $36/month on a typical 60-month loan, or around $2,160 more overall with interest. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
