Consumer Reports on Fuel Economy

A Consumer Reports Article took a look at fuel efficiency of several cars at 55, 65, and 75 miles per hour.  The first thing I was impressed with was the reality that going 55 was clearly a more efficient speed to drive at.  It makes you wonder if they should roll back all the speed limit signs in California back from 65.

Beyond that, the results were all relatively predictable, but even so it's nice to see Consumer Reports back them up.  Driving a hybrid at freeway speeds does effectively eliminate the advantage of having a hybrid.  Cars are more efficient than SUV's (even if the engine is the same size, unless you're driving in a vacuum I suppose).

After busy season I'll have to put together a spreadsheet to really analyze the time vs. money question they bring up, because I wonder if I'd be willing to make the trade-off of driving somewhere slower knowing that it was saving me cold hard cash (and CO2 emissions).
