On the other hand - Time is consideration in this thread.
Long thread does indicate lot of variables, but years ago I had a project 600 miles away from home.
Used 2 vehicles driving there several times, both delivering 32 mpg.
But one was 201 HP, the other 90 HP.
So even I kept the same cruising speed on long drive, the car with more HP was getting me there 1/2 hr faster.
Not noticeable at first, couple of seconds gained here on better acceleration, few second gained on long grade and on 7 hr drive it did make 1/2 hr difference.
