I know a lad with an M6, same thing really, 10 mpg on his commute, dont know whether there was a hint of exaggeration but I wouldnt have thought so, can do 20 if driven like a saint.
lol at 19.1mpg, like above post 15mpg is more like. Although article does say pressing on drops it to single figures which is just eye watering for on the road driving
dave what does your 535 do to the gall ?? mine does 32 on a run, its had a euc remap.
yeah mines be treaked, it does a average of 30 to 35 mpg with all sorts of mixture of roads, the new engine with 286 bhp, is better mpg again and has lower co2 output
book figs for 272 mpg = 35mpg combined, and the new 286 is 42 mpg combined, so looks good!
