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

One of the big downsides of the rotary is truly horrendous fuel economy. When the RX-8 first came out in the early 2000s, its mileage ratings of 16/22 city/highway mpg (stick shift) were just barely acceptable, but there days, with many crossovers hitting more than 30 mpg on the highway, those figures are truly atrocious, especially given respectable but certainly not neck-snapping power. Futhermore, it takes premium. If you're using the RX-8 as it commuter, fuel costs will add up quickly. In my predominantly around-town driving, I typically average between 16-17 mpg. My highest recorded average was 20 mpg on a highway trip at speeds around 75 mph. see full Mazda RX-8 review

The EPA numbers are way low compared with my real-world experience. The window sticker showed 18/25 and I have never seen less than 23 with my 40/60 city/highway commute. I think Mazda should develop a lean-burn economy cruise mode for this car. see full Mazda RX-8 review

For a small engine displacement and a relatively light vehicle weight, the gas mileage is weak. I usualy get around 19mpg, and that does not realy matter if I am doing all city or all highway driving. I think the real problem is in the sixth gear it isnt much different than fifth gear so it does not provide good fuel economy. see full Mazda RX-8 review
