Ah, the RCZ is a petrol, of course.I think mine can do that kind of figure, but I do tend to drive it like I stole it & I regularly hit the 18 ish mpg. I think theres no point having a point & squirt kind of car & then driving it like you can’t afford the petrol.
The efficiency of performance diesel BMWs is pretty astounding, we had an M-sport X3 on loan a few months back.
Nearly 300bhp I think, the thing really shifted.
Yet still between 34 and 37mpg.
Astounding that it could move like that and still do the same MPG as our lowly 114bhp Sportage.....
