Not to start another SUV war but there was a new gas mileage study that was just released, saw it tonight on the news. The study showed that SUV and large truck owners seemed to be much more likely to drive at higher speed limits on the freeway due to the fact that they felt much safer in their vehicle. The study went on to further show that the optimum speed for the average SUV or large truck was 45mph and that after 65mph the gas mileage dropped like a stone. By 75mph they were running at 30% less than optimum or equivalent to cruising at 15mph according to their graph. Smaller cars on the other hand showed to be optimum at 55-60mph and had a gradual decline after 65mph to where at 75mph they were only about 10% less than optimum. The debate now was weather to increase speed limits to help keep traffic flowing becuase the thought is that a steady crusing speed, even if higher, is more fuel effiecent than stop and go traffic. At the same time many police officers feel the increase in speed limit won't solve traffic problems or help with fuel economy and just suggest that people slow down. Just thought it was interesting with the recent posts that have been going around.
