I really don’t know if this is good or bad news but it seems that BMW is truly developing a diesel version of the new M5 F10 while an all-wheel drive version could be in works too. According to the first details, the new BMW M550dX will be powered by a tri-turbocharged 3.0-liter six-cylinder engine able to reduce the fuel consumption while the power amount will be slightly decreased over the gasoline V8 unit, which means fewer than 560 horses.
The new BMW M5 diesel model will benefit from BMW’s Valvetronic system, direct injection and revised cylinder head. A BMW insider confirmed that the M5 diesel is currently under developing, this being a crucial decision as BMW never offered a diesel M model before.
If we accord more attention to the rumors, the new BMW 550dX will develop around 525 horses and 680 Nm of torque. Therefore, we have the confirmation that a diesel BMW M5 will be available soon, the BMW source claiming that we could expect to see the model at the Geneva Motor Show, next year.
He also said: “To handle that amount of torque and the potential in tire-spinning forces, you have to go to all-wheel drive, otherwise you’ll be spinning your tires all day.”
