2026 Land Rover Range Rover Sport P550e Autobiography vs P635 SV Black

The Range Rover Sport P550e Autobiography starts at $118,700 while the P635 SV Black is $161,600. That $42,900 gap buys 7 meaningful differences.

The short answer

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.

If you would notice the 4.4L V8 mild-hybrid Turbo every week, the P635 SV Black makes sense. If not, the P550e Autobiography is the cleaner stop because this jump matters for the powertrain first and the trim badge second.

If you are budgeting this move monthly, the jump from the P550e Autobiography to the P635 SV Black is about $756/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $45,360 more by the time interest is counted. 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.
