A zebra is closer to the size of a donkey than a horse, and donkeys have about 5 horsepower, so a 200hp car would be about 40zf (zebra force). Also, since horses actually have about 15 horsepower, that same car would be about 13ahp (actual horse power). Llamas are also about the size of a donkey, so probably similar numbers.
