Bo's ready for the Big 10
Dodge, GM, and Honda all have engines that shut down half the cylinders at speed. Logic would say they should also shut down the cylinders when sitting in traffic. Does anyone know if there is a reason they can't do this. I've been wondering whether they can't or won't. This came about from wondering why don't big trucks use cylinder shut. Since they get about 5mpg saving 1mpg would be huge over the course of a year.
