I think the point of all this is that American cars are not perceived as being the most fuel efficient, even though a model by model comparison would sometimes disprove that perception. Overall, it's probably true and that's why many buyers believe it.
There was also a 2006 with the 5.3 and if you checked into the data there, you would have seen a couple of long trips that resulted in 23 MPG. I am not sure why that one has more than one data point, but I will have to see if I can resolve my SRX data into local and trip data.
I have done a couple of WOT runs with my SRX to see what the computer's fuel consumption says: the instant MPG reading was about 3 or 4 MPG; so I switched to the metric which said about 80 liters per 100 kilometers. Translating 80 liters per 100 kilometers into MPG is 3 MPG. So, one mile at that rate of consumption would be 1/3 gallon, or about 1/12 gallon for a 1/4 mile run. Perhaps a pint of fuel, or probably less.

My claims are based on the relationship of EPA numbers and my extensive personal experiences.
went to this site and looked up '97 Riviera. 2 users posted data. One gets 13.8 mpg with 90% city driving. The other gets 31.1 mpg with 90% highway driving. Just to show how much the data changes when you add just one more data point.
