2014 Mercedes-Benz Sprinter First Look - Truck Trend
NO ONE will see 37mpg from this Sprinter, just as I never saw 27mpg from my '04 Sprinter....even before I loaded it up. Driving empty at 55mph.....maybe! I got a maximum of 22 empty in real world driving. After loading it with all of my tools and storage boxes.......20.
Then when ULS diesel was the only fuel available, I immediately dropped 2 MPG to 18. My new '11 Sprinter 2500 high roof gets even less......16-18 in real world driving. Still, a solid 25-30 would be nice!
