BMW will withdraw its 3.0-liter four-turbocharged diesel engine in September. For the occasion, the Helix brand presents two special editions of the X5 and X7, logically named “Final Edition” and equipped with the 50d engine.

Diesel is an endangered species. This special edition that marks the end of the 50d at BMW contains only a few small, modest changes. They include door sills marked “Final Edition” and a long list of normally optional equipment that becomes standard. Among them we can count the laser headlights, semi-autonomous driving, head-up display, high-end Harman Kardon audio system, acoustic glass for the windows, specific interior trim and a few other small details.

Under the hood we therefore find the 3.0-liter quad-turbo inline-6 ​​that develops 400 horsepower and a maximum torque of 760 Nm. The X5 M50d – which is no other than an oiled alternative to the X5 M – only takes 5.2 seconds to go from 0 to 100 km / h and can accelerate up to 250 km / h.

The big Brother

The massive X7 M50d offers the same power and torque, but due to its size and extra weight, it is 0.2 seconds slower to reach 100 km / h. The top speed is the same: electronically limited to 250 km / h.

According to the WLTP cycle, the German manufacturer declares that the X5 M50d consumes an average of 8.3 l / 100 km and emits 218 g / km of CO2. The X7 M50d consumes slightly more: 9 l / 100 km and carbon dioxide emissions of 235 g / km. Consumption certainly high compared to many other Diesel, but surprising compared to performance.

We might as well not hide it: we are disappointed to learn of the imminent disappearance of this engine which had particularly seduced us during the test of the BMW M550d, the sportiest of the 5 Series Touring.
