Definitely tuning into the car now that I have done 10K or so. I have the 318d Msport tourer with the 18s, and if I sit at 70mph I can hit mid 50s no problems, 80 ish it drops to low 40s. Ran down to Leeds from Sunderland over the festive period and was in no hurry, set the CC at 58mph and 50 through the HUGE roadworks section, over 209 miles I got a nice 61.4mpg, with a full boot and two passengers. Best bit is the brother in law left 15 mins after me and arrived an hour later, said he was "not hanging about" but ended up stuck in a jam caused by a crash, his Mazda 6 2ltr petrol was averaging a while 29.4 on the same journey. I know which car I am happier with.
Would love a 330d but NEED it to stay in the mid 40s, and can't justify the mid 30s
Fuel prices are a killer
