The BMW X5 M50d is living proof that diesel-powered cars can be exciting. It’s a 400 PS (394 hp / 294 kW) and 760 Nm (561 lb-ft) super SUV with a quad-turbo inline-six oil burner under the hood.

Offered as a low-revving alternative to the full-blown X5 M, the M50d needs 5.2 seconds for the 0-100 km/h (0-62 mph) sprint and can go up to 250 km/h (155 mph). G-Power has, nevertheless, endowed it with a little more oomph.

The tuner didn’t say how fast the super SUV is with their software upgrade, but the output has been raised to 475 PS (468 hp / 349 kW) and 865 Nm (638 lb-ft) of torque. This is 100 PS (99 hp / 74 kW) less, but also 115 Nm (85 lb-ft) more, than the outgoing X5 M.

G-Power hasn’t detailed the X5 M50d project yet, but it’s clearly visible that it has new rims and the tuner’s logos replace the BMW badges at both ends.

The current X5 M has also been modified by G-Power – and the tuner has gone all out on this one. Thus, the 4.4-liter V8 has been boosted to 750 PS (739 hp / 551 kW) and 980 Nm (723 lb-ft) of torque, which should be enough to beat even the most expensive (stock) super SUVs out there.

There are other upgrades in store for different versions of the F15, third-gen X5 available. The X5 35i’s output can be increased up to 360 PS (355 hp / 265 kW) and the X5 50i can have as much as 570 PS (562 hp / 419 kW) with the performance software. The tuner can also extract 270 PS (266 hp / 198 kW), 315 PS (311 hp / 232 kW) and 380 PS (375 hp / 280 kW) from the engines powering 25d, 30d and 40d models, respectively.
