TrueDelta Reviews the Real Gas Mileage of the Volvo XC90

Volvo XC90 Real Gas Mileage: Pros
YearComment
2016 The old Volvo XC90's fuel economy was stuck in the early 2000s. When fitted with a 311-horsepower 4.4-liter V8 (last offered for 2011) its EPA ratings were 13 mpg city, 19 mpg highway. The 240-horsepower 3.2-liter inline-six that powered all first-generation XC90s in recent years managed little better, 15/21. The new XC90 is a couple hundred pounds lighter than the original one, and its only engine is a 2.0-liter four-cylinder. Two liters doesn't sound like nearly enough to motivate 4,400 pounds of all-wheel-drive crossover? Well, this particular engine happens to be both supercharged and turbocharged (the former to avoid the lag usually associated with a large, high-boost-pressure turbo) to the tune of 316 horsepower, five more than the old V8. The payoff: EPA ratings of 20 mpg city, 25 mpg highway. The highway figure is lower than that of the MDX (26), but the city figure is the best for a gasoline-powered fancy-brand three-row crossover. The trip computer averages during my week with the new XC90 largely confirmed these ratings. With a light foot in the suburbs I observed up to 27 mpg, a couple better than the Acura. Averages around 23 were common. Make frequent use of the boost and the trip computer average sinks as low as 14 mpg, but drive competitors similarly and they guzzle at least as much gas. Want even better fuel economy? Volvo will soon offer the above engine in conjuction with electric motors that bump total output to 400 horsepower. EPA ratings for the T8 hybrid haven't yet been announced, but they're expected to be impressive. Plus it will be possible to plug in the XC90 T8 then drive it about 17 miles on electricity alone. The downside? The T8 will cost $11,800 more than the T6 even after factoring in a $4,600 tax credit. Fuel savings alone won't justify this bump. see full Volvo XC90 review

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 But this large powerful car manages EPA ratings of 18 mpg city, 28 mpg highway, each one mpg better than the superceded V8.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

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
