Volvo XC40 trim comparison
2026 Volvo XC40 B4 Plus vs B5 Ultra
The XC40 B4 Plus starts at $43,900 while the B5 Ultra is $51,250. That $7,350 gap buys 7 meaningful differences.
The B5 Ultra adds AWD instead of FWD. If you deal with winter roads or need traction off-pavement, that could be worth $7,350 by itself. If not, the B4 Plus saves you the money.
The B4 Plus is the cleaner fit if FWD already covers the job. The B5 Ultra only earns the extra money when AWD is the reason you are shopping up.
If you are budgeting this move monthly, the jump from the B4 Plus to the B5 Ultra is about $129/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $7,740 more by the time interest is counted. The real question is whether AWD changes your day-to-day use enough to justify paying above FWD.
