Fascinating! The electric gives you about 40 hp boost almost all at about 5500 rpm.
The legend claims that the maximum power for orange is 102, and that the max hp occurs at 9.1 k. That rpm seems pretty unlikely for a Prius. Also the orange hp graph looks like it is declining when it falls off the graph at 6.5 k so to get back to 102 the torque must jump up again. I'd like to see that and have it explained - an extra auxiliary electric motor kicking in?
The brown graph, hp peak, 87 hp at 9.3 k, is still climbing at the edge of the graph so it can get there eventually. But what do you have to do to get the Prius engine to rev that high?
Or is the dyno computing the engine rpm based on tire rpm and gear ratio? Is the dyno computing engine torque based on gear ratio? Does the dyno know the gear ratio?
