BMW X5 review - how does it compare to the Porsche Cayenne? - MPG and running costs
BMW’s original SUV is still its best, still handling like a big 5-series. It’s just a shame it means so much less today…
MPG and running costs
BMW claims 47.1mpg for the 30d, an impressive number considering its more than two-ton weight figure. The M50d still cracks 41.5mpg over the same combined route, although we managed mid-30s in the 30d and high 20s in the M50d on test. This might have something to do with constantly flooring it in a high gear just to feel the surge of torque, but if you’re interested in buying an M50d chances are you’ll feel inclined to do the same. Petrol 40i models are rated at 33.2mpg, a number you’ll never reach anyway.
