Available on

The 5.0-litre supercharged V8 is sold in P425, P500 and P525 outputs across the Defender. Nothing mechanical differs between them. The output is set by the factory calibration, and this upgrade activates the P575 SVR calibration.

It's the factory calibration rather than a tune, so the engine keeps its factory behaviour and the upgrade stays in place through dealer visits and over-the-air updates. Power upgrades come bundled with Unlimited feature coding. Enter your VIN to see your exact price.

Common questions

Is it safe for my engine?

Yes. The P425, P500 and P525 use the same engine with the same internals. JLR built the hardware to run the highest output and set the lower ones in software. You're running the engine at an output it was designed, tested and warranted for.

Does it affect my warranty?

No software is altered, so there's nothing for a dealer to detect or flag. The car runs a the factory calibration on factory hardware. We've done this on well over a thousand vehicles and have never had a warranty issue reported back to us.

Will a dealer visit or an over-the-air update undo it?

No. Because the calibration is a factory setting rather than a patch, service visits and software updates leave it in place.

Can I go back to stock?

Yes, at any time. The original calibration is never removed, so switching back is the same process in reverse.

Can I buy the power upgrade on its own?

Power upgrades come bundled with Unlimited feature coding, since it's the same activation. Your VIN result shows the combined price.
