There are 19 downloads of the top-down racer on Vita and PlayStation 3 and eight Trophy unlocks every minute.
At least two PSN friendships are started and two challenges are sent every 60 seconds, and a new event is started by a player somewhere around the world every second.
The racer saw its second DLC offering, the 'Carnival Expansion Pack', released on PlayStation Network last week.
The update adds 24 new events, six racing circuits and eight new vehicles for £2.49 / $3.99.
MotorStorm: RC was launched on PlayStation Vita and PS3 in February, and offers cross-platform play across the two devices.
