Ford Bronco Power how Much Killo Watts?

You don't state the year, which makes a big difference. In North America, the 351 W was used from about 1980 to 1996. Maximum power was about 250 kw. In Australia, there was a stroked 302 (342 ci) that is sometimes confused with the 351w. As the Bronco is over 2 tonnes, you would be under the 130 kw per tonne threshold.

1.3 Giggawhatts but only when you are doing 80 MPH.
