I'd like to observe the behavior of both of these in the various modes with all 4 wheels up in the air. We could test and verify several things on the Outlander: * FWD only mode - the rear axle should not spin at all if it truly disengages * 4WD lock - both axles should spin at the same speed * Auto mode - does the front axle spin faster? Does the rear begin right away, or react only after the front axle spins? * Stability/Traction control - we could repeat all 3 tests with this On and Off For the Forester, we'd have 3 scenarios to test: * FWD mode with VDC off - again, is the rear axle totally disengaged? * AWD, VDC on - any side to side variance? * AWD, VDC off - reactive, proactive, same axle speeds, or what? The interesting part would be to observe the differences specifically. |

I'm sure the racing Pajeros cost them MILLIONS, which they had due to neglecting their street cars and the safety of their customers. Honestly, when you post statements like that, you are inviting flaming (baiting people). Smiley faces or not. To balance out your post, you could have mentioned that Subaru was also guilty of hiding defects and was forced to recall 2 million cars in 1997. Fair play.

Replying to: ateixeira (May 21, 2008 7:50 am) The jack stand trick won't work. I'm pretty sure that the AWD system takes into account TPS, and weight shift (F/R) as well to determine where to put the power. It also learns combinations of TPS, weight shift, speed to pre-emptively move the power. -mike

In my humble opinion, you can be guilty of hiding defects for just a month, you're still guilty of a serious lapse in judgment and ethics. Regardless, both companies are past this. Both have new, more transparent management structures in place. I find it unproductive to rehash the past. Especially considering that this is 2 full model generations behind us.

Replying to: kdshapiro (May 22, 2008 6:26 am) You obviously have your valid reasons. Conversely, I feel I have my valid reasons to believe that Mitsubishi makes great cars. One of many reasons being, we have owned 4 different models in several countries over the past 25 years (one of them for 7 years). Again, that's just my experience.
