Volvo XC90 trim comparison
2026 Volvo XC90 B5 Plus vs B6 Plus
The XC90 B5 Plus starts at $65,050 while the B6 Plus is $68,800. That $3,750 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 Plus if the 2.0L I4 mild-hybrid Turbo already feels sufficient for the way you drive. Step up to the B6 Plus only when the 2.0L I4 mild-hybrid powertrain is the reason you are moving higher in the lineup.
Think about this as a monthly tradeoff, not just a sticker gap. The B6 Plus adds about $66/month on a typical 60-month loan, or around $3,960 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.
