what manual transmission gets better fuel economy on the non-supercharged mini cooper, the 5-speed or the 6-speed?

 

the 6 speed has a higher gear ratio meaning better mileage (overdrive) so lower rpm's at speed

 

Venge, what are the final ratios ? 5 vs. 6 ?

 

i've noticed some significant fluctuations in MPG ratings on the Carmax website for the 2007 and 2008 mini cooper non-supercharged hardtop base model. it went as low as 23/32 for the 2008 to 32/40 for the 2007. fueleconomy.gov and edmunds.com give the same ratings of 28/37 for both years. carmax had different curb weights from year to year where the others didn't. i'm going to rule carmax's mini cooper MPG ratings as inaccurate and not usable. has anyone else ran into this? i want to move on a 2008 but i like to make sure of my findings. john

 

07/08 should be the same as there were no difference in motor/ tranny

gear ratios I had written down can't find them
