When I was 'stalking' my 2004 Forester, I had a chance to compare four different Forester configurations: 1)Forester X w/4EAT; 2)Forester X w/5M; 3)Forester XT w/4EAT; and 4)Forester XT w/5M.
For a climbing test, my salesman took me to a cul de sac that the west side cut into the hillside with a 30% cut slope before returning to the natural forested slope.
Configurations 1, 2 weren't able to ascend more than two-thirds of the way, with the 4EAT edging the 5M slightly.
Configuration 3 ascended slope to forested slope, backed halfway down, ascended to top of cut slope again.
Configuration 4 ascended slope to forested slope, backed halfway down, but was unable to start back up again.
THe XT configurations both had advantage over the X's, with limited slip rear differentials. In addition, both XTs had superior engine torque at low rpms (a function of the turbo-charged engine) that gave the Forester the power it could use with the rear LSD.
Configuration 3 was superior to Configuration 4, with it's ability to more gradually add on power (very difficult to 'feather' the 5M clutch in mid-slope).
Five years later, I had occasion to climb a fill slope in order to regain access to a road. The fill slope was 45 degrees, a slope possible because it was large aggregate (uniformly sized rock the size of uhmm, a lunchbox).
My FXT 4EAT with new but OEM Geolanders climbed the 50 foot grade easily at half throttle, without slipping, and in full control.
Tonight, an inch of rain has fallen on icy streets, and with the best Norwegian studded tires, I had sufficient traction to idle away without a slip...
Conclusion? The FXT has sufficient power to break traction on most slopes and tractive surfaces, but with driver skill, the FXT can master most slopes and surfaces, particularly with the 4EAT.
