I just realized that 05 subarus with basic engine (2.5 H4) are now rated to tow 2700 lbs (with trailer brakes). H6 is obviously rated more (3000 lbs). A significant increase compared to 2000-04 with the same engine rated up to 2000lbs. While I always believed (and hm... tested) that subaru can tow 2500lbs with ease, not sure why the change. Was anything upgraded in the 2005 drivetrain?

Thanks!

its not just the drivetrain you have to worry about... the braking of the vihicle is important... even though the brakes on the new gens are great they might not be ideal for heavy loads...

 

also the frame, suspension and all is taking a load... it would/could cause premature wear...

 

most likely the low rating is for warrenty purposes... i'm sure it can tow more but it also increases the chances of it breaking... i wouldn't do it...

 

the driveline has a very small chance of affecting the tow rating... because the don't change much... it most likely some strengthening of the frame or something that has changed...
