The ZF's transmission ratios are
4.696 3.130 2.104 1.667 1.285 1.000 0.839 0.667
Of course, it all depends on the final drive, but 0.667 is a fair bit of overdrive
(Yes, some 'Vettes have a longer top gear ...)
For the BMW X3, the final drive ratios with 8 speed are :
3.077 for the 2L diesel
3.385 for the 335i
The manual 2L diesel by comparison has 0.659 in 6th, but a 3.727 final drive
You can do like 47mpg in a Beemer X3 3L diesel automatic with some 260HP if you go easy on it.
Most folks buying that kind of car with that kind of engine simply don't have the resolve to do so ...
But as a wacky comparison, my up! has 0.796 top gear with a 4.167 final drive - it's got to make up for that measly 68 HP somehow
