Last night, while on a road trip to beautiful Tofino on the west coast of Vancouver Island, we got updated from 4.2 (.41) to 4.2 (.42). The download seems to have occurred WHILE driving the 4 hours here, and then I did the update in the hotel parking lot. Today I was giving friends rides and found what might be a significant improvement in this release-- traction control stability. I did a number of 0-60 runs on dry to damp pavement and with the Pirelli winter tires. I found that the traction control seemed much more stable. Several times before (on 4.0 or 4.1), I found that the car would fishtail notably doing a full-power start. I was actually rather unnerved by it. Now, the starts are very stable, with little or no wheel spin, and even in I am at the limit of adhesion, and there is some wheels spin, the car remains absolutely stable at blasts straight ahead. BTW, I think I may have sold my two friends on either an S or an X each!
