Subaru Legacy Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2013	4dr Sedan 256-horsepower 3.6L H6 5-speed shiftable automatic AWD	The downside of the H6 is not great gas mileage, but for what you are getting, it is not bad. On the highway with cruise control have managed to get about 30 mpg. In a mix of city and highway it gets 23 mpg. In city only it gets 18 mpg. Again, for AWD not bad, but not great. Want better gas mileage, get the H4 engine. see full Subaru Legacy review

2010	4dr Sedan 170-horsepower 2.5L H4 6-speed manual AWD	A bit thirstier than I had hoped - but the AWD probably has a lot to do with that. see full Subaru Legacy review
2009	4dr Sedan 170-horsepower 2.5L H4 4-speed shiftable automatic AWD	The fuel economy with a 4 cylinder 170 hp engine is pretty disappointing at 22-23 mpg. The AWD system is responsible for some of the loss but I also drive an AWD Acura TL SH-AWD with a 6 cylinder 305 hp engine that is only marginally worse at 18-19 mpg. see full Subaru Legacy review

TrueDelta Reviews the Real Gas Mileage of the Chevrolet Tahoe / Suburban

Chevrolet Tahoe / Suburban Real Gas Mileage: Pros
Year	Comment
2015	You didn't expect to see fuel economy among the reasons to buy a Tahoe, did you? Of course, fuel economy remains well below that for most smaller, lighter vehicles. But General Motors has substantially improved the SUV's efficiency by adding variable valve timing, direct injection (fuel is injected under high pressure directly into the cylinder, rather than into the manifold), and cylinder deactivation to the 5.3-liter V8. EPA ratings improved from 15 city, 21 highway to 16/23 with 2WD and 16/22 with 4WD. I observed averages as high as 21 in the suburbs and 26 on the highway, quite impressive for an 80-inch-wide, 74-inch-tall, three-ton vehicle. Transitions between V4 and V8 operation are not perceptible, with the engine usually in the former mode when not accelerating, even at highway speeds. Ford took a different approach to improving fuel economy, replacing its 5.4-liter V8 with a turbocharged 3.5-liter V6. The resulting EPA ratings of 15 mpg city and 20 mpg highway are better than before, but aren't as good as the Tahoe's. My trip computer averages were similarly two to three mpg shy of those observed in the Tahoe. see full Chevrolet Tahoe / Suburban review

The vehicle actually garners a respectable 21 mpg on the highway. see full Chevrolet Tahoe / Suburban review
