Trying to intentionally get better mileage on a 6000 lbs beast is really an odd goal. It's not a Prius...and doesn't share any characteristics of a high mileage vehicle. It's going to range from 12-20 depending on length of trip, type of driving etc.

Flip the script and it's like saying, how can I get my Passat TDI to accelerate like my 911? It's not going to happen.

You could drive all day long with the windows open vs. the windows closed and you might get a slight delta in MPG...hardly worth the effort. The purpose of this car is NOT to get good MPG, it's a different driving experience than a Prius or Passat TDI hyper miler.

It's a waste of time and effort to convert an elephant to a cheetah...

It's like wearing track shoes to dance Tango...doesn't make sense.

You'll gain 1-2 mpg...not that meaningful...but mods are still fun nonetheless...just be realistic on the expected outcome!

To be fair, and maybe to clarify, I’m not trying to discourage the modding process. Goodness knows I’ve done a ton of it as well on this RRS and loved each one so I'm sorry if my message came across as negative in nature.

I’m just trying to clarify that being concerned about getting MPG on the RRS is somewhat of a misplaced goal…the sum total of all of the modifications won’t net much materially, but shouldn’t be a barrier to trying, just not likely to prove to be significant.

If one is terribly concerned about trying to massively improve MPG on this vehicle, it seems to be an odd goal since the vehicle is an elephant and will always be one. I see folks suggesting “coasting”, closing windows, right lane driving, soft right foot, etc..and those are great techniques for hypermiling in vehicles such as a Prius or VW TDI. I just don’t think they do much for the RRS.

It does bring up another point…each vehicle lends itself to a certain style of driving. The 911 is always more likely to be driven in a spirited manner…that’s the nature of the sports car and the engine makes beautiful music when run thru the gears. The RRS can be driven WOT from time to time but is a great cruiser, can gobble up vast distances with incredible comfort and poise and make its way thru blizzards, sand, rock, snow and feel exceptionally sure footed, but is a thirsty beast. The TDI is just a plain vanilla commuter getting great MPG, but it doesn’t do it with much style or acceleration.

Each one does its job very well…trying to get one to do what the other does just doesn’t make much sense to me…sort of like those dudes in Honda Civics with monster spoilers on the back thinking that’s going to make the vehicle fly faster than before…Not going to happen!
