Different manufacturers and even different years of the same manufacturer's 3100 V6 engine may have different horsepower ratings.
To find the horsepower for a specific vehicle, you'll need to consult its owner's manual or a reliable automotive resource like Edmunds, Kelley Blue Book, or a similar website, specifying the year, make, and model.
