the hemi has a lot of power but is constantly hunting for right gear because it's torque curve is small. I really don't care what other say about gassers as I go by the seat of my pants and the diesel wins hands down, JMHO.;)
And there in lays the answer! The torque curve of a diesel covers a much wider RPM range that the gas engine does. The diesel requires less shifting when going up a hill because of the wide torque curve.
All of that may be true, but given a test with two vehicles as closely matched as they were, towing the same load, and both going full throttle, the gas engine consistently won. Apparently even if the gas engine was searching for the right gear, it found it and still won. Even tho the diesel had a wider torque curve, it still lost, with or without a load.
The facts are that if either engine is in a motor home, the coach will still get to the top of the hill. Sometimes the gasser will win the race and sometimes the diesel will win the race to the top.
