The XSi also has a pull-type clutch. That's the only model I've worked on so can't comment on others.
I had to look up the difference between pull-type and push-type clutches though as didn't know why the 2 designs existed. Apparently for any given amount of effort to flex the pressure plate on a pull-type (equates to force required to depress clutch pedal), the clamping force of the pressure plate on the clutch when not depressed is higher than with push-types. All to do with fulcrum points apparently!! In short, the pedal on a push-type clutch that was strong enough for a gti6 or XSi would require quite a bit more effort to depress. As it is, they're quite hard work compared to a lot of cars!
I guess hydraulics takes the worry about driver effort out of the equation & more cars have push-type clutches these days?
