"Manually locking rear differential was replaced by "electronic differential lock" (EDL) (Difflock imitation, detects wheelspin via ABS sensors and applies brakes to the one spinning wheel, thus transferring torque via open differential to the opposite wheel which has more traction). EDL works at speeds up to 80km/h (50mph) on all quattro models (on non-quattro models: up to 40 km/h (25 mph)."
That quote is referring to the Quattro generation IV system, starting in 1996. The Subaru has a limited slip differential, but has no system to apply braking, so it's a "pure" AWD system.
We have an '07 WRX and an '02 Audi A4 Quattro. I love the WRX, way more fun to drive, but the traction control in the A4 makes a HUGE difference for less skilled drivers. You basically can't slide it at low speed, the brakes just stop it. Kinda cool if you don't know how to drive out of a slide.
whoa didnt know that, i had an 01.
Last night i went around a hard 90 degree right turn with a downward fast slope. When i got into the turn i realized it was covered in ice, i started to drift towards the oncoming minivan in the other lane, But thanks to no traction control I pushed the pedal down and drove right out of the corner, sideways or not at least i didnt pull a Not-E and hit an innocent.
Today we received several inches of snow. By afternoon most of the roads turned to ice, and since the temps hovered around freezing the ice was wet and very slippery. I took both cars out on the same route around my neighborhood, back-to-back within minutes of one another, and had a chance to compare first-hand Audi quattro v. Subaru AWD. I went through several iced-over roundabouts, intersections, curves, and straights.
In this corner:
2002 Audi A4 1.8t quattro sedan, 5-speed manual, Sport Package, Winter package, 245/45R17 Michelin Pilot PS2 winter performance tires, ESP (traction control) turned on, 3/4 tank of gas.
And in the other corner:
2007 WRX wagon, 2.5L turbo motor, 225/45R17 Yokohama W.Drive winter performance tires, 3/4 tank of gas. Mods include SPT catback exhaust and 20mm rear sway bar, otherwise stock.
The car pics were taken before the snows came, obviously. Something I think is interesting is that according to data I've found online, both cars weigh the same to the pound. The Audi feels like a heavier car. The WRX feels way faster.
Up until today I had not driven my two cars back-to-back on snow and ice. I mentally had told myself that the Subaru was slightly better in foul conditions, but had to base my judgement on memory of how each car drove on previous days. Since today is Sunday and I had nowhere to be, this was a perfect time to try them out in identical weather conditions one right after another.
I drove the WRX first. On several of the more slippery sections with a goose of the pedal I could break the car loose and it would powerslide sideways until all fours hooked up. It was very predictable and controllable, but it was a slide nonetheless.
Next I immediately grabbed the keys to the A4 and took it on the same route. On the same slippery sections where the Subaru had slid, the Audi's traction control light would blink (meaning it was being put to work), and the car would slip only a moment then would find its way into the correct direction of travel. I tried several times to break it loose but when the ESP would kick in, I more or less could not skid out of control! It was really dramatic how much more controlled this car was. It was not even a subtle difference, but a major one. I was quite impressed.
With the ESP off the Audi felt similar to the Subaru, but since it has less horsepower it took more tall-skinny pedal to break it loose. All in all it felt very controlled.
The verdict: Both the WRX and the A4 have good snow and ice manners, but with the traction control left on, it's Audi quattro FTW!
Thanks for reading.
