5-speed shiftable automatic AWD		 The 3.0L i6 is rather underpowered, and it's hard for me to squeeze even 22 mpg out of my X5. Most of the time, I get close to 20. Most V8 X5s from this generation get 16-18 mpg. see full BMW X5 review

TrueDelta Reviews the Real Gas Mileage of the Audi A8 / S8

Audi A8 / S8 Real Gas Mileage: Pros
YearComment
2013 Fuel economy might seem an odd, "why to buy" for such a large, powerful car. But this large powerful car manages EPA ratings of 18 mpg city, 28 mpg highway, each one mpg better than the superceded V8. In suburban driving the trip computer typically reported averages in the low 20s, but as high as 25.5. We're a long way from large luxury sedans that had trouble cracking 18. The BMW is rated a bit higher, 19/28, but this is close enough to call it a draw. If you want even better fuel economy, Audi how also offers a 240-horsepower diesel with EPA ratings of 24/36. But the TDI is only available with the long wheelbase and will also cost you another $3,700. BMW offers no comparable car on this side of the Atlantic. see full Audi A8 / S8 review

2004 4dr Sedan, ext. 330-horsepower 4.2L V8
6-speed shiftable automatic AWD		 The Audi A8L is an interesting car if bought used. As it is a premium model, it is often bought on lease or by rich people. It is also all aluminium - when sold they are usually in great condition. The fuel economy is good for its size - about 12 miles a gallon city and 22 highway. For an 8 cylinder, all wheel drive performance car this is not bad. However high gas prices make it nota very economic choice for the gas version. With the introduction of the diesel version means used vehicles will come onto th eused market in about three years (2106). Fuel consumption will be better. see full Audi A8 / S8 review
