The big causes of torque steer are suspension design and halfshaft length. Because the engine is longitudinally mounted (and centered in the engine bay, ahem to older Audi models) equal length half-shafts are easy. For most transverse mounted FWD or AWD vehicles it's not so easy, but many foreign makes have bothered to go through to effort to make it so. Cadillac may have not... and if the half-shafts aren't equal length, the shorter one gets more torque to the wheels. (It's a U joint, not a lever arm.) The suspension also plays a very large role but that's not as easy to explain. I'll wimp out and have you trust me, or ask someone else to take up the gauntlet. Anyway, Subaru has addressed both. -Colin

I experienced it when I drove my cousin's Grand Am GT. I let out a big "Whoa!" Man, am I spoiled with AWD. Dennis

V8 torque + FWD = recipe for torque steer. Cadillac always seems to be a step behind the trend of the times - most luxury cars are going RWD. Even the Passat has torque steer, though VW hypes the "virtual axis" front suspension. Put simply, you're simply asking the front wheels to do too much! Carry 60% of the weight, steer, and oh, by the way, apply torque to the pavement at the same time! Soobs divide the traction duties, and the weight distribution is better to boot. -juice

I'm with Colin, it ain't just AWD. Tauruses don't do it, neither do Camrys or Accords, because they have put the money into the engineering Colin described. Only in high HP cars is it acceptable, IMHO, like the 9-3 Viggen
#35 of 21536 High HP by paisan Nov 29, 2000 (10:26 pm)
The caddys refered to above are kinda high horsepower and torque... I just hate FWD in general... -mike

More problems for Ford... Besides just having the 5th recall (the largest yet!) for the Escape, it's now reported that the all-new OHC 4.6 alloy block V-8, scheduled for the soon to be released 2002 Explorer 4-door has been delayed due to problems. Will it ever end?? Bob http://www.blueovalnews.com/

High HP? Uh yeah, if you consider 275-300 HP "kinda high". For the weight of the vehicle and the size of the tires, it shouldn't have the torque steer problem that it does if it were engineered properly. A better solution though would be RWD. -Colin

A better solution still would be AWD. :-{) Bob
#39 of 21536 Achiva vs. Legacy... LOL! by kostamojen Nov 30, 2000 (7:07 am)
I got to drive my moms GT Limited to class today cause the Old's had some stalling problems yesterday (It doesnt happen to me for some reason, just when other people drive it) and plus it was raining today, and I do love the AWD in rain Anyway, theres this zig-zag on a 4 lane road I go on every day (S curve, 35mph, very tight) and the Achieva goes about 50-55 before it starts seriously peeling out and the front of the car starts to give away (its really scary too, the opposite of fishtailing) while the '00 Legacy can go about 60 without peeling out. However, the Legacy is seriously out-powered by the achieva (3.3 V6 vs. 2.5 H4) which I could easily beat a stock RS with (And these civics just love challenging me, and I just play along staying right next to them without even trying... its hilarious). The Legacy has this really nasty "stall" thing it does when accellerating from a stop (Its impossible to peel out with...), but its got good enough umph when accellerating when your already moving for sure... Anyone notice how funky the steering wheels position is though? You just cant get close enough without seriously bending your legs (im 5'10"), its hard to get in a good brasive posture... (the slick leather and flatness of the seat backs dont help) Dont get me wrong, the Legacy is a damn good car, in fact, I got a little to close to a curbing while parking and the car just hopped right up without hesitation (!) like it wasnt even there... I still like the RS better, and cant wait for the new Impreza line...

That phenomenon is called severe understeer. Though some Soob owners may not be very familiar with that... I believe the stalling you're referring has to do with the AWD drivetrain. There is more mechanical resistance in sending power to four wheels, and so it takes more to get it going. Once on the move, you hardly notice. Try the tilt wheel feature if you haven't. Can't help with the leather - that's why I choose cloth. Bob: I'm surprised. The mod V8 has been in the Crown Vic for years, and it's been quite reliable. Ford seems to be in a down cycle. -juice
