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 But this large powerful car manages EPA ratings of 18 mpg city, 28 mpg highway, each one mpg better than the superceded V8.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
 

TrueDelta Reviews the Real Gas Mileage of the BMW X3

BMW X3 Real Gas Mileage: Pros
YearComment
2013 While the boosted four has a clear performance advantage, the swap was motivated primarily by the push for better fuel economy. EPA ratings are 21 mpg city, 28 highway, vs. the 2012 six's 19/25. An Audi Q5 comes close, 20/28, but with 211 horsepower isn't as strong. Despite weighing about 400 pounds less than the X3's 4,112, a Ford Escape with a similarly spec'd engine does no better. A Mercedes GLK350? 19/24. The Volvo is even worse. Compared to cars, the X3 doesn't fare as well. The roomier, nearly as heavy 528i rates 22/33. The crossover's larger frontal area and higher ground clearance take their toll as speed climbs. In our real-world sub-freezing suburban driving, the trip computer usually reported about 21 once the engine was warmed up, matching the EPA rating and quite good for a powerful, two-ton, all-wheel-drive vehicle. Engage an aggressive Eco Pro mode for a Prius-like throttle response and ultra-low rpm shifts, and mid-20s are easily achievable while high 20s are possible. I even observed 32 over one short trip where the lights were in my favor. But the cars behind you won't be happy. Conversely, enjoy the turbo at every opportunity and fuel economy will fall into the teens. A defeatable standard auto start/stop system operates a little more smoothly than in last year's 3-Series, but not as smoothly as it ought to. see full BMW X3 review

2009 4dr SUV 260-horsepower 3.0L I6
6-speed shiftable automatic AWD		 Have noticed as low as 10 mpg in start and stop city driving. Average for daily driving is 14 mpg. It uses premium fuel so driving this car is already very expensive. see full BMW X3 review
2006 4dr SUV 225-horsepower 3.0L I6
5-speed shiftable automatic AWD		 City driving fuel economy is not bad for an SUV. I average around 16MPG battling heavy traffic and my need for “enjoying using the accelerator”. Highway mileage is not so great. Cruising at 70-80MPH returns around 22MPG. see full BMW X3 review
