"...this could possibly be termed an issue with the operator, rather than the vehicle, is the "torque hole" that the car has from roughly (from my driving experience) 3k RPM to 4.5K rpm."


I have about 350 miles and I am also having Nav/voice recognition problems. Hopefully a SOA tech person will telephone me today to assess.

As for the "torque hole", there has been much discussion about the dyno curve and the perceived drop in power/torque in the region you described. You can find details with a search here and at subarubrz forum.

My take away is that this is a result of the combined types of fuel injections in the BRZ, imparting a kind of barbell torque curve - higher at low and high rpm's (sorry for butchering the explanation...I would have to go find the discussions to provide the techie talk). One assessment was that this could/should be looked at as a a low end boost, rather than a mid curve drop.

In any event, I look at driving and shifting from 2000 - 3200 rpm as my economy mode, and will look at 4000 - 5000 rpm as the sport/passing mode. Of course, I have not got there yet, until 1000 miles.

Hope this helps.
