Enjoy that M8.

Not immediately, but I believe with the documented procedure, they always advice not to exceed 4000rpm and full throttle situations and certainly restrain from combining both the first 1200mls.

The reason is simple: by avoiding this, you limit strain on pistons, crankshaft and bearings in the engine, but also the transmission. This allows for more gradual material honing/grinding. Although tolerances are super small these days, I understand that frictional parts are deliberately designed to have a honing/grinding phase. Only this guarantees a perfect fit for many years to enjoy.

You know what to do. Drive it like you stole it.

Stumbled across this thread and noticed a lot of misinformation posted. Some of which can be confirmed by reading the owners manual and some of which has been proven from a BMW dealer with before and after dynos.

There appears to be a myth that additional power is unleashed when the 1200 mile service is performed (my SA told me the same) but it is just that; a perpetuated myth

False. You can use LC (as someone already mentioned) it is not disabled and unlocked @ 1200. The manual says do NOT use LC during break in.

As for the additional power myth please see the video below from Classic BMW where the M3 gains 28hp after the 1200 mile service . It dynos 301.6 to the wheels before and 329.6 after. The amount of power gained may vary among all the different M engines but it's certainly not a myth.

Wrong see video below.

Those of you quoting 4000rpm must be talking about a different engine or M car.
Page 300 in the M8 manual (and page 274 of the M5) states:

"Drive at varying engine and road speeds, but do
not exceed 5,500 rpm and 106 mph/170 km/h.
Avoid full load or kickdown under all circumstances"

The only thing I would make sure of is that they documented the milage on the odometer in your lease. I leased several Porsche's and I treated them with kid gloves until my Boxster. That one got driven like it was leased.
Enjoy your new toy! It's beautiful!

Glad to hear about the LC but for the extra power I see no proof related to modern M-cars. Our M8 certainly felt the same before/after...

A F90/F92 pre/post 1200 mile service dyno would be more relevant to me than mentioning what's in the manual

That may be coming from the N63 in the M850i as its manual states:

Up to 1,200 miles/2,000 km

Do not exceed the maximum engine and road speed:

4,500 rpm and 100 mph/160 km/h.
Avoid full load or kickdown under all circumstances.

Yesterday, my M8 coupe had it's 1200 mile service. For what it's worth, both my service advisor and the M-certified technician working on the car told me that the vehicle is shipped from Germany in "transport" mode, and that after the 1200 mile service, additional horsepower becomes available. Unfortunately, neither was able to quantify how much. The debate continues.
