It says right there - 1HP. For comparison, a Vespa is around 12HP. Vespa - Wikipedia
It could be made to move a car, slowly. Consider that it takes between 16000 (my RX-7 conversion) and 20000 (my Tesla model S) watts to move a car down the highway at 60 mph (~100 kph). One HP is 746 watts. You are not going to be able to move a car more than a couple of MPH with a 1HP motor. If you had a 21 hp motor you could eventually get to 60 mph in a fairly small car. It might take minutes to get to that speed. You need a lot more than 21 hp in order to accelerate to your desired speed. Additionally you need additional electronics to convert the 120v battery into the AC that the motor needs.Would these work with a 120v battery pack for a small go medium sized car? I will be using a manual transmission with it.
