No, it’s front wheel drive Glos Guy. I would expect 4WD to be a couple of mpg worse. The B48 is a stonking engine. I’ve not known one better.
Wigwan, as you know your engines can I ask you a question? I haven’t driven the current model X1. but I did have a 520i loan car around 18 months ago and was really impressed with the engine. I thought it would seem sluggish compared to the 520d I had at the time, but it wasn’t too far short and I thought it perfectly adequate even for a car of that size and weight. But my question is whether or not this is the same engine as in the X1, as the PS output is less in the X1 than the 5 Series? Also, can I ask how you find the road noise in the X1? A number of reviews seem to suggest it lets a lot of road noise into the cabin. Like many manufacturers, I know that BMW concentrate more on sound insulation the further up the range you go. My 5 Series was near silent and you couldn’t tell it was a diesel from inside, even at idle. Our Tiguan is considerably noisier, both from an engine and road noise perspective, but I don’t know how much of the difference is down to it being an SUV so less aerodynamic.
