2013 facelift is 250 or 300 bhp?

[Panamera2018]

Hi there. I'm buying a facelifted panamara but am confused with what is advertised versus the write ups. All latter half of 2013 facelifted models are showing 250bhp on auto trader and pheads and from 2014 it shows 300 bhp. I'm thinking it's a software limitation on the website where it's applying 250 bhp due to the fact the first half of 2013 was the older model? Or did the engine get a revamp in Jan 2014? Just want to make sure all 2013 facelifted models are 300 bhp? Cheers.

February 2014 was a major rework of the engine with very few parts the same.
The main difference was water cooling the turbo which allowed an increase in turbo boost resulting in an increase from 240bhp to 300bhp.

Hope that helps.
