If you look at "rated" fuel economy numbers a 2007 Yaris is rated 29 city/35 hwy, the xB is listed at 27/32. I would expect part of the hwy loss on the xB due to it being a toaster on wheels, with that in mind I would guess that this change is about a 2mpg loss in a Yaris - but worth it for the acceleration.

I think that statement just pushed me over the edge to track down an xB transmission for next summer. Thanks Jason, I hate you sometimes
