Have our trucks got too much power yet?
I've often thought about all the energy being wasted with braking applications and exhaust braking on down grades. It's only a matter of time before our rvs will have electric drive axles to help hold...

I cant think of an application where two different displacement turbo diesels are offered in the same vehicle but the Honda Accord Sport is available with two different turbo gasoline engines of different displacement and I know the smaller engine is rated to get somewhere around 10 - 15% better fuel economy. It seems to me the Honda engines are both designed to make similar power per liter. In the example I'm talking about .... a 6.7 making 475 horse vs a 5.0 making 300 I would expect a greater spread in the low load fuel economy than in the Hondas case because the 5.0 liter can be designed with a higher compression ratio than the 6.7.
You see it a lot in boats and assuming you don't use those extra horseys, they difference is typically to small to measure.
