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

2010	4dr SUV, ext. 320-horsepower 5.3L V8 6-speed shiftable automatic 4WD w/low range	I don't really have any complaints about this vehicle for our uses. But many people do buy them and don't use them for their intended purposes, and then complain about paying for gas. Well, it is a truck, after all. see full Chevrolet Tahoe / Suburban review
2010	4dr SUV, ext. 320-horsepower 5.3L V8 6-speed shiftable automatic 4WD w/low range	Even though its fuel economy is great for its size, it still uses a lot of gas see full Chevrolet Tahoe / Suburban review
2007	4dr SUV, ext. 320-horsepower 5.3L V8 4-speed automatic 4WD w/low range	In mostly local suburban areas we average 12 MPG. Highway only can reach 18 or 19 depending on load and hills. see full Chevrolet Tahoe / Suburban review
2007	4dr SUV 320-horsepower 5.3L V8 4-speed automatic 4WD w/low range	Fuel economy is not great, but it's not horrible either. Again, this is a full size SUV on a truck platform. How much can anyone truly complain when you know this going in? see full Chevrolet Tahoe / Suburban review

2005	4dr SUV 295-horsepower 5.3L V8 4-speed automatic 4WD w/low range	Poor gas mileage... but I knew this before purchasing it so this is not a problem for me. If gas prices scare you... then this is not the vehicle for you. see full Chevrolet Tahoe / Suburban review
2005	4dr SUV, ext. 295-horsepower 5.3L V8 4-speed automatic 4WD w/low range	At $4 a gallon and a 32 gallon gas tank, you feel it every time you fill up and if you drive a lot in the city, at 15 mpg, you will fill up often. The vehicle actually garners a respectable 21 mpg on the highway. see full Chevrolet Tahoe / Suburban review
2003	4dr SUV 285-horsepower 5.3L V8 4-speed automatic 4WD w/low range	The obvious. 16 MPG highway. Enough said. see full Chevrolet Tahoe / Suburban review

TrueDelta Reviews the Real Gas Mileage of the Buick Regal

Buick Regal Real Gas Mileage: Cons
Year	Comment
2011	The Buick Regal and Chrysler 200 both weigh substantially more than just about any other front-wheel-drive midsize sedan. Add all-wheel-drive, and both weigh nearly two tons. Curb weight is the enemy of fuel economy. The Buick's turbocharged four-cylinder engine is more efficient than the Chrysler's V6, so it has an edge in the EPA's city test, 19 vs. 18 mpg. But the Chrysler's automatic transmission has three extra gears, for a total of nine, so it has the edge on the EPA's highway test, 29 vs. 27 mpg. The Ford Fusion, though far from light, has an edge over both: 22 mpg city, 31 mpg highway. see full Buick Regal review

2012	4dr Sedan turbocharged 270hp 2.0L I4 6-speed manual FWD	For being a turbo 4, I expected slightly better MPG (I average 26mpg mixed with premium). When adding in the Trifecta Performance tune on the car, I average around 29mpg, with the added HP/TQ. What gives, GM? Uncage this beast! see full Buick Regal review
2011	4dr Sedan 182-horsepower 2.4L I4 6-speed shiftable automatic FWD	City EPA mileage was lower than I would expect for a four cylinder--should easily best 20 vice 19. see full Buick Regal review
