2026 Land Rover Range Rover Sport P550e Autobiography vs P635 SV
The Range Rover Sport P550e Autobiography starts at $118,700 while the P635 SV is $152,000. That $33,300 gap buys 7 meaningful differences.
This trim jump changes the engine from 3.0L I6 phev to 4.4L V8 mild-hybrid Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the P550e Autobiography if the 3.0L I6 phev already feels sufficient for the way you drive. Step up to the P635 SV only when the 4.4L V8 mild-hybrid Turbo powertrain is the reason you are moving higher in the lineup.
If you are budgeting this move monthly, the jump from the P550e Autobiography to the P635 SV is about $587/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $35,220 more by the time interest is counted. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
