Hi Scott go to München, my dealer told my car was there waiting. You have enough info to recognise it. Take some pictures and post it here.
X3 M / X4 M [Official] The BMW X3 M (F97) and the BMW X4 M (F98)
- Thread starter Giannis
- Start date
In 2019, BMW introduced the X4 M and X4 M Competition (F98), being the first time an X4 had a M version. The X4 M is fitted with a 3.0 L S58 straight-six that produced 473 horsepower with the Competition models producing 503 horsepower. Full M models can be fitted with full M specific M Performance Parts. These include a splitter, spoiler, sport steering wheel, carbon fibre vents and kidney grilles.

If you are not aware BMW is heavily sandbagging output with turbo M motors then you simply have not been paying attention for the past decade. Here is yet another example in the new 2020 BMW F98 X4M Competition and its S58 motor which is rated at 503 horsepower.
Well, here it is making 520 horsepower to all four wheels in Arizona 119 degree heat on 91 octane pump gas:
BMW's horsepower ratings are just a joke at this point. They say 503 at the crank and it has more than that at all four wheels. This is easily a 600+ horsepower car.
Even if you go with conservative 15% drivetrain losses which are traditionally reserved on a Dynojet for a RWD manual vehicle that would mean output is 611 crank horsepower. If you go with 20% losses, we are talking 650 horsepower.
The G80 M3 gets this same S58 motor and basic drivetrain in a lighter package. 600+ horsepower only makes sense. Why? BMW since the E46 M3 increases horsepower by approximately 75 whp each generation. They simply started sandbagging with the F80 M3 massively.
E46 M3 - 275 whp
E92 M3 - 350 whp
F80 M3 - 425 whp
G80 M3 - ~500 awhp
The E92 M3 to F80 M3 horsepower rating went from 414 to 425 at the crank. Yet, wheel output increased by 75+ horses. Explain that.
With the G80 prepare for a dragster that will be well into the 10's tune only.

On top of the diagram is written:correction factor standard, which could mean that the mechanical loss is calculated in this test.If you are not aware BMW is heavily sandbagging output with turbo M motors then you simply have not been paying attention for the past decade.

I think the Germans in general are sandbagging especially in the turbo era some more than others. The B58 is overachieving for the rated power.I also think they are sandbagging for B58 40i models

S58 is going to be a monster of a engine....I see a few engine awards adding to BMWs already impressive tally with it.
“Not yet convinced the BMW M S58 motor is a beast? The tuning for the platform is in its infancy as the S58 motor literally is just hitting the streets. Despite that, the platform is knocking on that 10-second door with just a JB4 and some ethanol.
At 6000+ DA (density altitude) no less. These will eventually run 10's with a tune and race gas.
Keep in mind this is a 4500+ pound SUV:
This thing is a rocket!
A JB4 + E85 and the G80 M3 will be in the 10's. Go ahead, save this post to reference as it is going to happen.”

What an ugly car the X4 is! Shame on you, BMW

Compatibility with JB4 is fantastic. For years it’s been an plug and play way to tune the B58.

Although JB4 is available for other manufacturers it’s synonymous with BMW.
TotallyHi Dalab,
it looks we use the same sources
, after so many months I liked seeing them to vary in changed colorsSince 26 hours I'm the very happy owner of this...
Let's the fun begin

BMW M GmbH, formerly known as BMW Motorsport GmbH, is a subsidiary of
BMW AG that manufactures high-performance luxury cars. BMW M ("M" for "motorsport")
was initially created to facilitate BMW's racing program, which was very successful
in the 1960s and 1970s. As time passed, BMW M began to supplement BMW's vehicle
portfolio with specially modified higher trim models, for which they are now most
known by the general public. These M-badged cars traditionally include modified engines,
transmissions, suspensions, interior trims, aerodynamics, and exterior modifications
to set them apart from their counterparts. All M models are tested and tuned at BMW's
private facility at the Nürburgring racing circuit in Germany.
