According to several sources on the net, the US market 2000-2001 Impreza RS has a rear viscous LSD. At least with the 5MT.

 

This is in contrast to the 98-99 models (strangely, the presence of an LSD on the 2000-2001 models is not listed on cars101.com).

 

Now to my question. Do the automatic (4EAT) 2000-2001 RS models also have a rear viscous LSD?

 

If you know the answer, I would appreciate if you could add to your post where you have this information from. Is it from sales materials, a workshop manual, original window sticker, or simply hearsay?

nobody knows the answer to this question!?!

I looked for a brochure on it (I have a decient collection) but of course I don't have the info you want. BUT, I can tell you how to find out.... jack up the whole rear (both back tires) and spin one of them....if the other one spins the same way you have an LSD if it spins in the opposite direction then it is an open diff.

Thanks, but I wasn't looking to know how to tell if a car has an LSD. I am looking for a new car for my wife, which I will also occasionally be driving. She wants an automatic, so I was thinking of a 2002-3 WRX with auto. However, to save money, I am also considering a 2000-1 Impreza RS w/ auto.

Because winter traction is important, my interest in the 2000-1 Impreza RS depends on whether it has a rear LSD like the WRX does.

 

So my question remains: Does the 2000-1 Impreza RS with auto have an LSD?
