High 20s to 30 MPG on E320 4-Matic!
I have had this car since new, it had 7 miles on it when I picked it up. I am almost at 51,000 miles now and I would say that it has been getting very good fuel economy. I have seen some posts about this, but I just now got around from taking the photos off from my phone.
The E320 4-matic’s sticker says that it should get 18 city and 24 highway. If I drive around town (with a lead foot) for just a couple of miles at a time, I do only get 18. However, as soon as the engine warms up the MPGs really start to climb. I log all my fill-ups at the pump. Since day one, my car has averaged 22.7 MPG. I don’t think that is too bad!
I accelerate rather quickly whenever possible, then I roll as much as possible and maintain momentum. I have worn two sets of tires so far, but I still have the original brakes (all 4 corners) and they still have over 50% left! I guess that I am not doing too bad, right? I usually inflate the tires well above what it says on the fuel lid (still bellow the max PSI on the tire), but I still always keep the 5 PSI difference between the front and rear. I also have K&N air filters. There are mixed arguments about if these techniques actually help fuel economy, but I think that it works for me.
The pictures bellow are from a couple of trips I have taken. I can always get a minimum of the 24 MPG that the car is rated for, even if I average 80 MPH. However, as you can see, on one of my trips even when I have driven over 1,100 miles (which includes city traffic driving and filling up with fuel) I can still get just over 24 MPG. This is particularly good since the average speed on the computer is about 74 MPH. You can obviously assume that I was not driving slowly during some parts of the trip (since it still set an average this high). This trip was also in the dead of winter, with winter gas and snow tires.
The other trip computer pictures are from a trip from Denver to Salt Lake City and back. Also in the winter with snow tires and a hell of a headwind! I did not really stop so that is why I was flirting with 30 MPG. However, I was still averaging 70 MPH. If I could only drive slower. . . I have at times gotten 34 MPG with summer tires and summer gas!
I can only imagine what I would get if I had one of the new Diesels! I will probably buy a W212 Diesel in a few years to replace my S6 (which also gets quite good mileage).
