Transmission Differences between the 28i and 35i
Could anyone help shed some insight on the differences in transmission used in the 28i versus the 35i?
The 28i has an 8-speed transmission whereas the 35i uses an (older) 6-speed transmission. I thought there must be a reason why the 6-speeds are used on the more powerful car as it seemed inferior to the 8-speed, especially when all the X3's and X5's I see in a deal use the newer-looking 8-speed transmission.
What does that do performance-wise?
Maintenance? (probably more expensive on the 8-speed... how much?)
Any opinions at all?
