I assume there is a difference in curb weight between the two. The average fuel mileage on the S420 is 19.2 mpg, while the S500 is 17.1 mpg. The records for the S420 are only from September of this year, while the S500 records are close to two year total.
I keep very detailed fuel records, so I have a high level of confidence in my statements. I would add that both cars are in the same condition and are very close in mileage (267k) although the S420 is three years newer than the S500. Not sure how, if at all, that would come into play." Could it be something as simple as the tires on the 420? Are they similar tires? Less rolling resistance on the 420?
