Agreed.. It was an engineering decision based on what systems the car is equipped with. If they used a more sophisticated cam system with variable lift, they could have addressed the torque dip.. By giving us most of torque down low, compromises were made..
I have no issues with the dip.. It's not that bad.. It's there.. But isn't an issue in everyday use.. Driving "normally" you don't run into the dip and the car pulls descent down low.. Want to play some, just keep the revs up and work the gears for the upper rpm power curve..
A good compromise.. Unlike some high revving engines 2L engines that are difficult to drive in traffic due to the tq band being in the upper rpms
