While I am not the one to try and explain the physics of it let me try. You are comparing apples and oranges now.(cars and trucks) Cars...... These are made for city driving. While the big V8 could burn the tires off it is wasted energy. A 4 cylinder will always get better mileage but you have to reduce the size of the car and give up horsepower for it to work. So we make the car as small as we can then put a smaller motor in it to up MPG. Trucks.... They do not have that option in fact trucks are bigger than in past years. So what do you do? Well they added flaring for air flow. But the biggest thing they did was change gear ratio. To do this they had to up the horsepower. And it worked; trucks have bigger motors now yet get better mileage but only on the highway. Pickups that tow..... Now we are trying to have the best of both worlds. We want it to be a car one day yet tow a tractor at 70 mph the next day. Sorry but it just does not work that way so they pay for it in MPG
