+100Nm

Effortless pace

800Nm means the M440d barely has to try. It gathers speed from low revs in a way that feels almost electric.

Point and go

Out of a roundabout or up a slip road, the extra power and xDrive traction get it moving with no drama.

Questions

M440d remap questions

How much bhp does a BMW M440d xDrive remap add?

A G22 M440d goes from 340bhp and 700Nm to around 400bhp and 800Nm on Stage 1: 60 more horsepower and 100Nm more torque.

Is the M440d the same engine as the M340d?

Yes: the same twin-turbo B57 at 340bhp and 700Nm, and the same Stage 1 result of around 400bhp and 800Nm.

Can you tune the M440d Gran Coupe?

Yes. Any M440d with the B57 is tuned the same way. Check your reg to confirm your car.

Does the M440d’s mild-hybrid system still work after a remap?

Yes. We change the engine and gearbox software only. The 48-volt system, xDrive and every driving mode work as before, and the car runs on our 4WD dyno with nothing unplugged.
