M135i first dyno at Evolve

I thought you guys may be interested to see the first dyno run we have conducted on a stock M135i. Car is the 8 speed Auto running 97 RON supermarket fuel.

I had an extended drive in it and was very impressed. Will be replacing our MINI with one very soon as many of our customers have bought/ordered these.

Those are extremely interesting numbers, thanks for the share mate! I'm quite surprised by how much power is lost from the engine to the wheels, I thought it would be less, not 50hp!

Wow 341 hp that's more than what dealers and car magazines are saying I thought maybe +\- 10hp would be normal but a difference of 20hp common. Why would bmw short sell how much power the engine has?

They can't measure how much is lost, so it is just an estimate. A significant part of the lost power is actually rolling resistance from the rear wheels.

Hi Imran,

I think this is consistent with 1M dyno numbers that you guys performed in the past. By saying that I don't mean that they have same hp or tq, I mean that they are both underrated similarly and dyno numbers also show a parallel difference in line with advertised numbers. I believe there is a slightly bigger difference in tq of two cars compared to relatively small difference in hp.

If possible, could you show this chart also including the 1M's chart, on top of each other? Would love to see curves of two from the same dyno both performed by you (understood not same day but still gives a good idea)!

And just a reminder, German Sport Auto M135i test included a dyno run as well and result was similar.

I take it M135i in reality has around 340 ps and 490+nm while 1M has around 360 ps and 550+nm in average. Both more than enough in real world driving

EDIT: In the meantime I found your original Evolve thread in the 1M Sub Forum. Numbers were as follows:

whp 302.5 (difference vs M135i +19.6 hp)
flywheel bhp 363.4 (vs M135i + 22.3 hp)

wtq 355 (vs M135i + 55 lb.ft)
flywheel tq 427 (vs M135i + 64 lb.ft)

Still waiting combined dyno chart curves from you, please!

Any plans to develop software for any of the other 'F' Series BMW's? Specifically the N20 125i?
