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

Chevrolet Tahoe / Suburban Real Gas Mileage: Pros
YearComment
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

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
2007 4dr SUV 320-horsepower 5.3L V8
4-speed automatic 4WD w/low range		 not economical see full Chevrolet Tahoe / Suburban review

4-speed automatic RWD		 V8 sucks gas like a ... V8; 18 MPG in all around driving 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

Infiniti G Real Gas Mileage: Pros
YearBody/PowertrainComment
2007 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD		 My average for the life of the car is 21MPG. Not too bad for a car with this power and my lead foot. see full Infiniti G review
Infiniti G Real Gas Mileage: Cons
YearBody/PowertrainComment
2013 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic RWD		 Can live with it because of the performance, but wish the mileage was better and premium fuel was not required. see full Infiniti G review
2013 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD		 What the powertrain giveth, the fuel economy taketh away. Nissan's VQ engines just seem to be thirsty - if you commute in heavy traffic, especially for short trips, don't be surprised at 15.5-16 mpg tanks. I don't know what mostly-highway commuting would look like, but maybe 22-25 mpg depending on driving style. see full Infiniti G review
2010 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD		 To be honest, it is exactly what I expected, so no real beefs with it. That said, if you are looking for a car that gets better than 19 or so combined, this is not it. Decent freeway miles (24-27/g) but in city it is hard to beat 16/g. see full Infiniti G review
2010 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD		 Fuel economy is poor - about 19 MPG average. see full Infiniti G review
2009 2dr Coupe 330-horsepower 3.7L V6
7-speed shiftable automatic RWD		 You do not buy a performance car and expect to get good gas mileage. At a 5 mpg or greater difference from my last car, it is taking some getting used too. see full Infiniti G review
2009 2dr Coupe 330-horsepower 3.7L V6
7-speed shiftable automatic AWD		 average 18 in town 24 highway. see full Infiniti G review
2009 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD		 With such a large displaced engine and so much power you will find that you will have so-so mpg if you drive mainly in the city like I do. Especially if you are a "spirited" driver like I tend to be. I am averaging about 14-16mpg 95% city. On the highway its a different story. I have averaged up to 28mpg @ 78mph, I kind of wish I drove more on the highway. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
6-speed manual RWD		 While not terrible, ~20mpg is by no means phenomenal. Relatively comparable cars get ~23-27mpg, but typically also have smaller engines which explains a good portion of the difference. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Takes a lot of fuel... 14L/100km about. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Not too great. My average is 19 - 20 mpg, mostly city. see full Infiniti G review
