^ Exactly. A good part of it is driving a vehicle you want and/or need, and then getting the most out of it. If it weren't for Ecomodder, I'd be getting about 10 - 11 mpg city, rather than the 13+ I'm getting currently commuting to work. I'd also still be doing 70+ on the highway getting 15 - 16 mpg tops.

The key to large cars is for them to be aerodynamic, and to primarily use them as highway vehicles. The weight is killer in the city, as is the poor idle efficiency of large engines. However, on the highway with good aero and tall gearing, they do fine.
