Finally got my 2017 GLE550e December 12,2016. 4 1/2 months after it was built. So far everything works perfectly. The delay was because they had to revise the window sticker mileage expectations after the VW cheating fiasco on alternative fuel vehicles. Mine says 43 MPGe. Combined gas and electric. And 21 MPG, gas only. Combined city and highway. I can now compare this to my wife's S550e 2016. They have the same exact motor. First the GLE550e is about 400 pounds heavier and is 4 wheel drive. The S is obviously more streamlined. And the gearing is different. I'm running more RPM at the same highway speed. So I'm expecting less MPG in the GLE. The main thing is your driving pattern. The shorter the trip between charging, the higher your MPG. I do mostly short trips around our town. Many days I do 8-15 total miles, and then it's back on the charger. Often the gas engine never starts. It sows 99.9 mpg for the day. I like to push the select button on the dash and change the setting from hybrid to eMode. This allows more push on the gas pedal without turning on the engine. I get adequate acceleration for most driving, when I've floored it, I was shocked at the power. 0-60 is supposed to be about 5.3 seconds??? I think the electric torque boost really helps. Anyway,this is my first full tank after getting the car. I've had more short driving days than normal, and I've now driven 450 miles on the tank and I'm at exactly 50 MPG, with 331 miles on total electric! I still have just over a half a tank of gas left. This will not be normal, when I do longer drives, but it is possible with many short days. My wife drives about a 26 miles commute a day and in 8,000 miles has never gotten less than 34-36 MPG on a tank. The dashboard number might be off a bit and I'll check it when I get gas in about 350 miles! Since the GLE550E is basically identical to the GLE400, with the addition of the electric, and I believe the base price is about $1,000 more, but then I got a $4,085 federal rebate, it ends up being $3,085 or so LESS, and .8 seconds quicker to 60, plus much better mileage, I think this is the way to go. I'll try and post a picture of the dash board numbers. Until the next refil. John.
