[s-cars] 6 speed?

[Taka Mizutani]

That is not totally correct-

In the OEM application UrS 6-speed manual for the AAN or ABY engine, 4th,
5th and 6th are spaced closer together and the top gear is the same as the
original 5-speed transmission's 5th gear.

If you install a turbodiesel 6-speed transmission, they have a taller 6th
gear.

To answer the OP, there can be several reasons to upgrade:
stronger 1st gear in some applications
closer gear ratios make it easier to stay in the powerband, esp. if you're
running a big turbo with a lot of lag
"cachet" of having a 6-speed
having a taller top gear if you get the right transmission

There are so many variants of transmission, with/without Procon-Ten "ears",
trans cooler, different ratios, slightly different mounts (depending on
whether or not you get the transmission from a V-8, C4 S4/S6 2.2 or 4.2, B5
S4, C5 A6, etc.).
