I piped in over in your other thread, but remember neither the 1.6 nor the 1.0 have any aspirations of being a "fast" car. Mine is a 1.6 and as long as your willing to flog it, I wouldn't call it slow. I have zero problems merging onto the highways around here, or getting up to speed from lights. The real fun is in corner speeds with the Fiesta of every engine option. I have not driven the 1.0, but rule of thumb is more torque more pull(depending on gearing of course). The 1.0 has won engine of the year for three years in a row, if that helps.
