Literally just passed 5000 miles and suddenly the engine is smoother, pulls harder and even sounds different to before.

I noticed this with the same (similar) engine in my last XF, except that took 10,000 miles exactly to do the same thing.

Anyone else noticed a step change in performance/NVH at a similar mileage?

I do wonder if these cars have an ECU setting somewhere to keep the power below "max" for the first X thousand miles, in lieu of running in? Which it certainly did not get, lol. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

It was very noticeable in both my Evoques at 3000 miles, almost like the Dynamic button had been pressed but haven't noticed it in my RRS which now has 7600 miles on it after 12 months 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Well, I listened very carefully again this morning on the commute, and all the effects noted earlier are still there. It even seems to have affected the gearbox - that seems more ready to change down and hold gears for longer. Like being in "sport", or the more subtle gearbox map change you get in "dynamic".

I don't think it is particularly faster, just a smoother, more lively engine and a more enjoyable drive.

I have to admit that I had been concerned originally about the NVH in this car - I never ever felt V6D engine vibrations through the body on my Jags, but this Sport was far rougher. Better now. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

Don't forget the gearbox adapts to your driving style..

Just gone thru 5000 miles on my MY16 and there is more grrrr to the engine which I translate to mean more torque available at lower speeds, makes me want to drive it even more  P400e HSE Portofino Blue and Ivory Seats.. it's like a yacht!!

Not really, the 'box has always been a model of smoothness.

But now it seems happier to let the engine pull harder from lower revs. MY2016 HSE D SDV6 - gone due to fuel dilution problems.

Just gone through 5000 miles myself. Can't say I notice a difference.

LOL, I had the magic one!

It is still driving better than pre 5000 miles though. And the fuel consumption has changed, too. 1 to 2 MPG better. MY2016 HSE D SDV6 - gone due to fuel dilution problems.
