Ah, interesting. It certainly makes sense theoretically. Advanced combustion engines like the N55 are really efficient under constant load, but their weak spot is sudden changes to the load. Having the electric motor assist for a second when you punch the throttle allows more time for the engine to ramp up its output and that might save a bit of gas compared to forcing the engine to rapidly respond in sport mode.
And I drove just about as spiritedly as I dared without being downright reckless.
