2K for half second is not bad when you consider what it would cost to achieve the same on a ICE vehicle. Too bad they're not offering a Christmas deal on FSD.. I'd roll the dice on it for 2K LOL


Of course I don't have AP either and am currently looking at a $10k cost. lol

i just installed mine...yeah its a given that its quite abit faster but the thing that I noticed is when driving normal from 20-50 mph the car just feels like its 300 lbs lighter...like its effortless to cruise at 40 mph now.

That is what the extra 50 lb ft of torque does. It makes our heavy cars feel a lot lighter than they actually are expecially down low where you need all that torque to get moving.
Another thing I've been pondering:

Seems like efficiency would go down a bit since it's easier to produce more power. Wondering if others feel the same, but I think I'm seeing worse efficiency now (though not too concerned about it...). It will be better than a P anyway.

But here's my actual thought: I'd expect that a future update drops where we can select chill, standard, or sport driving styles to mitigate this. It was probably done this way (chill, sport only) because then it was just a config change and no change to the GUI which would be a bigger software change.

Curious what 'yawl think about that theory. To me, I would use the standard option and go into sport when I want to have extra fun by having a different driver profile I can easily swap to.

more power now so yes less efficient
Though that depends on you ; should be same efficiency if driving very light on the pedal

doubt we will see 3 acceleration options in the future
The current P model also only has sport and chill

is one motor (speculated) to gain more from this boost vs the other. 980 vs 990. also how do I check my motor, I have a 5/2019 build awd
I would "probably not" as I think the AB upgrade tuned all front and rear DUs the same, even if that means to the limits of one particular rear DU P/N.
Had to :D

well we know for a fact this upgrade is not to the limit of either motor type as it actually lessened the power from the rear motor
This update boosted the power from the front considerably which is similar to how the P is setup

agree this update is the same for 980 and 990

A third party BMW update is way more and bifurcates the warranty.

Noelle Performance Tunes F90 BMW M5 to 850 Horsepower

It adds 250(!) hp and 170(!!) lb-ft of torque for $3699. Put another way, you add almost 42% more horsepower for about 4% of the car’s cost and maintain some drivetrain warranty.

That’s insane.

Would like to see that thing run a 1/2 mile against the new roadster, P100D, and a 720s just for grins.
