After 30-50mi test intervals on a long trip with my R320 CDI diesel here are my results: 55mph = 30.8mpg over 30 miles
60mph = 29.8mpg over 30mi
65mph = 28.2mpg over 30mi
70mph = 26.5mpg over 50mi
75mph = 24.8mpg over 30mi
entire trip was almost 900mi & 13.5hrs with an overall avg. of: 64mph = 28mpg (overall includes 4 bathroom/meal brakes, all other results above were non-stop 30-50mi test intervals)
FYI for comparison purposes I did some test drives before buying this car and with identical test drive routes i got 23.8mpg in a deisel R320 vs. 17mpg with unleaded gas R350. (about 29% better milage with diesel engine, yet in my area diesel is same price as Premium unleaded and diesel was about 10-12% higher than low grade unleaded. And diesels are "supposed" to last about twice as long as their unleaded counterparts. So, still better value eitherway with diesel.
