    ** The P85D top speed is currently electronically-limited to 130 mph. In the coming months, we will be able to upgrade the car free of charge to enable a 155 mph top speed. This free update will be available for the lifetime of the car (not limited to the first owner). Additionally, an over-the-air firmware upgrade to the power electronics will improve P85D performance at high speed above what anyone outside Tesla has experienced to date. In other words, the car will be better than you experienced. This free upgrade will be rolled out in the next few months, once full validation is complete.

    My guess is this will be related to idling one of the motors, probably the rear one, to both improve highway efficiency as well as increase the top speed as the front motor is likely geared higher.

    The gearing could be the same but due to smaller size the sweet spot for efficiency could still be at a higher speed/RPM.

    Good point, could be.

    Has anyone perused Tesla's patents to see if there are any hints on this topic?
