When it comes to fine-tuning a BMW product, the aftermarket specialists from G-Power are perhaps the most dedicated. They know BMW in and out and carry out exceptional power upgrades under the hood, and we have seen some pretty examples on that matter.

We have seen lots of BMW models, such as the X5 M or X6 M, along with the M2 Coupe or M3/M4, receiving impressive power kits. The tuner`s latest project involves the above BMW M550d in its former generation, this one also getting its fare share of power under the hood.

In the visual department, the mods aren`t that many, the top of the line version from the 5-Series receiving some slight updates at the front and rear bumpers, along with the new 20- and 21-inch front and rear HURRICANE RR alloy wheels, available in three colours, ”Jet Black”, ”Gun Metal Grey” and ”Stardust Silver”.

As for the upgrades under the hood, the BMW M550d got the tuner`s D-Tronik 5 V1 power module, meaning modified turbochargers and ECU remapping, all significantly raising the car`s stock power.

As the tuner says, the power module is not always active, and that to protect the engine. The ECU remapping activates the car`s new throttle using a special program that the driver activates only in certain situations.

The stock model comes with a 3.0-liter six-cylinder engine with a good 381 horsepower and 740 Nm of torque, but with the new power module, the M550d is now capable of delivering 435 horsepower and impressive 850 Nm of torque. The sprint figure is not given at the moment, but we should expect fresh details in the upcoming period.
