Volvo S90 trim comparison
2025 Volvo S90 B6 Plus vs T8 Plus
The S90 B6 Plus starts at $58,300 while the T8 Plus is $65,650. That $7,350 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.0L I4 mild-hybrid to 2.0L I4 phev Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 2.0L I4 phev Turbo every week, the T8 Plus makes sense. If not, the B6 Plus 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 T8 Plus adds about $129/month on a typical 60-month loan, or around $7,740 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.
