Hub dyno's are certainly more favourable as a measurement.
There is just way fewer variables that are estimated on roller dynos - no strapping down, estimating loss on the tire friction, just a lot less to worry about and therefore less to 'accidentally' overshoot on settings.
I am not sure if the car is under rated really, the comparison runs of hub dyno's between this new model vs the old model really show that the last car was over rated. Old vs new has gone from ~110kw to ~150kw at the hubs.
I think the updated (refresh) model averaged a bit higher ~115kw.
