2026 Land Rover Defender 90 P525 V8 vs 110 P635 OCTA Black

The Defender 90 P525 V8 starts at $114,400 while the 110 P635 OCTA Black is $168,700. That $54,300 gap buys 6 meaningful differences.

The short answer

This trim jump changes the engine from 5.0L V8 to 4.4L V8 mild-hybrid Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.

Start with the 90 P525 V8 if the 5.0L V8 already feels sufficient for the way you drive. Step up to the 110 P635 OCTA Black only when the 4.4L V8 mild-hybrid Turbo powertrain is the reason you are moving higher in the lineup.

Think about this as a monthly tradeoff, not just a sticker gap. The 110 P635 OCTA Black adds about $956/month on a typical 60-month loan, or around $57,360 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.
