Hi all
I have been planning on getting a series 2 sportwagon but I don't think I will be able to afford one .
I do a lot of highway ks and a bit of hills so I would like a economical cruiser.
I understand the 5 speed auto apparently uses a bit more fuel than the 4 speed auto?
I wonder why?
The specs say top gear the 4 speed has ratio 0.7 and the 5 speed has 0.75. not a lot different to make that much difference I would have not thought.
So
at 100km/h what RPM are each gearbox reving at
at 110km/h what RPM are each gearbox reving at
If the diffs aren't the same maybe fit the 4 speed auto diff into the 5 speed car? To lower the RPM at highway speeds. Maybe an option?
Thoughts?
