Question Autos vs. Manuals

Auto and manual Imprezas use two different differentials. Manuals use the viscous limited slip, and autos use the Haldex center diff . The difference between the two is described below:

"Subaru's automatic transmission cars normally run 90% front
and 10% rear power dist. An electronic module senses wheel
speed difference front to rear and a hydraulic clutch can start
to "lock up" the centre diff and send more power to the rear.

Subaru's manual transmission cars run 50-50 power dist. The
centre diff is a viscous type. When wheel speed differences
occur between front and rear axles, this viscous diff starts to
lock up to send more power to the other axle." (http://www.audiworld.com/bbs/a4/9936/messages/622.shtml)

I have a couple of questions.
Which one is faster? (ex. 0-60, Quarter mile ...)
Which is more reliable?
Whats there charateristics under different driving conditions (dry, wet, street and rally) ?

No 4EAT uses the Haldex Traction center differential. Similar in some ways-- perhaps. It's not Haldex though, and in fact it pre-dates the Haldex system.

My auto is the same speed as a stick in 0-60, and my Subaru Impreza brochure had the stats as the same.

I think that above 100mph, the stick would pull away, but this is unverified. The Civic SI pulls away as soon as I shift into 4th gear, but up until then I am faster.

Then consider yourself lucky to own the fastest auto, cuz the auto is not nearly as fast as the manual, stock vs stock.

The auto is slower because you can't launch it over the stall speed of the torque convertor which is around 2200 rpm's. I think if they both started from idle they would be about the same.

Get real guy's. In these cars, the difference in speed and acceleration between auto and stick is not really worth discussing. The numbers probably don't differ enough to matter. Especially if the guy driving the stick misses a good shift.

What it's really all about is FUN! You can't beat a stick for the chuckability factor and additional control it gives the car. Heck, even a Geo Metro with a stick can be fun if you focus on throwing it around instead of 0-60 times.

But then if you commute in heavy traffic every day, a stick can get old, especially if you have a heavy Clutch.

My take? Auto for trucks, SUV's, luxury cars, stick for sports cars or even sport touring, e.g. BMW.

I had a 98 Auto conv Vette. Sure it was fast, but the Suby is Sooooo much more fun to drive with the stick.
