Tragically the V5 states 265kw or 355bhp

But if anyone who hasn’t a clue asks, it’s 388 - I have a picture to prove it !

I realise there are differing versions of bhp, all quite close in value but does the 355bhp / 265kw stack up with the 360bhp spec? 265kw / 355bhp is suspiciously like the pre-MY2020 spec, I wonder if BMW bothered changing the declaration for the 2020 spec in Europe.

As far as I understand it the 2020 MY cars had a power hike to 382bhp however the WTLP regs in Europe and addition of OPF dial this back to 360 - may be the case that BMW UK haven’t yet notified the DVLA

Anyone had a 'UK' MY19 M40i on the dyno with the PPF yet ?

I did a rolling dyno run today with Charlie in Surrey, Surrey Rolling Road LTD, awesome chap!

My car is 2019 UK M40i with OPF, production date 2019-03-15.

I've got little over 9300 miles right now and around 1200 miles since last oil change. Car is stock for most- I only changed charge pipe and fitted aluminium Masata charge pipe. I use Esso premium 99 and that's what dyno has been been run on.

On the pre-run car got to 388.8 before xdrive kicked in and started limiting the engine power.

That's interesting and thanks for posting. My 2019 M40i is now at just under 11,000 miles and I am tempted to pop over to see Charlie.

I follow The Performance Centre in Sunderland a lot of FB and they seem to reckon about 365-375 bhp for a post OPF M40i.

Surrey Rolling Road does have a reputation for being accurate and that is a reputation built over many years ... even if he is now in Hampshire
