The test subject this time is no other than the BMW X6 M50d F16, a six-cylinder 3.0-liter engine. The Fostla Tuning team first carried out a full wrap in black chrome. In this context, the “accents” on the roof, mirrors, door handles, and diffuser in Black-Brushed, as well as the window tinting, are also worthy of praise.

Even on the stock model, the performance is overwhelming. It reaches 100 km/h in just 5.3 seconds and accelerates effortlessly above this threshold. The 2.2-tonne body is a perfect match for this remarkable engine and the eight-speed sports automatic gearbox that comes as standard. When you consider that the BMW X6 M50d weighs in at 2.2 tonnes, that 5 seconds and a bit is all the more impressive.

The high weight does however take its toll when braking and cornering. The inertia of the heavy bodywork is often felt. The ideal weight is up to 1.8 tonnes – the maximum point at which the suspension, brakes, and laws of physics are in perfect harmony with a profound sense of safety.

Even so, for all its weight, the car drives almost flawlessly. Cornering dynamics are very good thanks to the precise steering system and Adaptive Drive technology, which eliminates roll-on corners. With 19-inch wheels and a 255 mm tire width, the suspension handles impeccably. The move to 20-inch wheels and 275mm-wide tires sacrifices a lot (a lot!) of comfort, as we saw in tests with the X6 ActiveHybrid and X5 40d M Sport.

At 100 km/h you’re running at 1,500 RPM in the 8th gear, and consumption is around 7 liters/100 km. As I said, a very efficient powertrain. On 560 km driven in equal proportions on and off-road, I got an average consumption of 12.5 liters/100 km during the 560 km test in total. The consumption is somewhere between 13 and 14 liters/100 km, which is about the same or even better than the rest of BMW’s 3-liter diesel engines.

It is worth mentioning that compared to the next lower engine, the 40d (303 hp), torque is available over a 500 rpm higher range (so from 2,000 RPM to 3,000 RPM in the X6 M50d compared to 1,500-2,500 RPM in the 40d). Torque is also significantly higher in the diesel M, 140 Nm more.

On the exterior, the wheel and tire combination that the fostla.de crew used from the HAMMAN shelf really catches the eye. It consists of HAMANN Anniversary Evo II Black Line rims in 10.5×22 ET40 with 295/30 R22 tires on the front axle and in 12×22 ET28 with 335/25 R22 on the rear axle, along with HAMANN spacers. The HAMANN wheel arch trims, which are also installed, serve to widen the wheel arches. Likewise, the HAMANN lowering springs do not miss their effect.

Finally, the engine with standard values of 381 hp and 740 Nm at fostla.de had to undergo a PP performance stage 1 power increase in combination with a BMC sports air filter and now provides 443 hp as well as 845 Nm for free. The total conversion costs amount to approx. 19,000 EUR.
