Well to find out, we’ve got our hands on the most powerful petrol & diesel BMW X7s to see just how different they really are! So let’s check out the stats… Starting with the M50d, it’s packing a 3-litre straight-six diesel under the bonnet that can produce 400hp and 760Nm of torque. Power is sent to all four wheels via an 8-speed automatic gearbox, and it tips the scales at 2,460kg. If you’re looking to pick one of these up now, it’ll cost around £88,000.
