kwhelan 241 Report post Posted June 9, 2018 just quietly cause this is a bit sacrilegious, but a 3.7 v36 model 2008/9 skyline coupe has all the power and features, ride is amazing and won't cost you a cent in repairs year after year, and fuel use is phenomenally good boot is rubbish 1 Quote Share this post Link to post Share on other sites

balancerider 758 Report post Posted August 11, 2018 just offering a data point for 'performance' diesel. I've recently acquired an F31 335d touring w/ N57B30 engine - 230kw/630Nm. Open road economy ~6L/100km with overtaking etc. best i've seen is 5.1/100 indicated for auckland-hamilton in free flowing traffic with range of 1050km from a 57L tank. My commute is 24k (welly-porirua) and averages ~7L/100k for this in current conditions. My impression is fuel economy is substantially better in warmer weather - tends to be closer to 8L/100k if cold. 1 Quote Share this post Link to post Share on other sites
