Overdrive drove the Palio MJD inside Fiat's Ranjangaon plant and their article has the specs rated at
80bhp and 190Nm of torque. The car being driven had the words "Palio Multijet Diesel Prototype" written across it's front where the number plate usually fits and OD mentioned that the car wasn't the final production vehicle yet.
BSM mentioned 70bhp and OD says 80bhp.
Seems like Fiat is still fine tuning the Palio MJD.
