E39 m5 gas mileage

Hi. Newbie on this site. I'm in the market for an E39 M5 and I would like to know what the gas mileage looks like. I work 14 miles away one way and just want to know if it would be a good daily driver. Any input will be greatly appreciated.

E39 m5 gas mileage

If I'm not mistaken, according to BMW, it is 13 MPG in the city and 21 on the highway. Combined MPG could be around 16-18 MPG based on your driving habits and if the engine components are working properly.

It will be a poor daily driver as the car will not gte up to temperature ...as a result the car will run in open loop mode running rich for most of the time, leading to fouling and oil shear.

Never mind that anyone worried about gas mileage isnt a good candidate for E39 M5 ownership, where the repair and maintenance costs will FAR outstrip the pittance a few hundred gallons of fuel a year will cost.

Mein Auto: E39 ///M5
I commute just over 20 miles roundtrip to work. I average about 16mpg mixed (city/hwy) On the hwy I've seen mpg go up to around 26mpg, and in the city as low as 8-10mpg.

Like ARD said, if your in the market for an E39 M5, I don't think fuel consumption should be your #1 priority

That's what I get - though I get high 20's - low 30's if it's all freeway. Downhill, I get 98 mpg. "Around town" really depends on how liberally the throttle pedal is used...

Wrong, wrong, and wrong. I get up to running temp by 5 miles. My M5 is my daily driver, and it's awesome. I have about 130k miles so far with very few mechanical issues, and the maintenance cost is the LOWEST of any car we've owned, including my wife's Audi, a Ford, a Nissan, a Toyota, a Mazda, a Mercury, 2 Chevrolets, and a Subaru. We just added a Honda to the mix for the middle kid, so we'll see how that goes.

I have the same commute. I average around 18-19 combined.
I love the trip back from Big Bear though... coasting down the hill the whole way, my trip average stays above 30mpg for most of the way home.

I made it all the way from downtown San Francisco to our So Cal home on one tank of gas and 50 miles to spare on the range display.
