Why torsen & haldex systems?

[ge0rge]

Why dont audi just use the torsen style 4wd instead of haldex on the a3's etc?

Because the A3 has a transverse engine layout.

Never seen an A4 with a transverse motor - are you sure?

[ge0rge]

not even the first gen ones? I was young when he had it probably didnt know what transverse was at the time

[Dr G]

Nope, even the 80 before it was in-line.

[ge0rge]

Ok cheers

Probably price related as well. Torsen is great but expensive in comparison to haldex.

(1) Haldex is cheaper. So its ideal for the less expensive models.
(2) Haldex fits nicely into the 'transvers' golf platform. (A3 TT Golf, Skodas etc)
