TrueDelta Reviews the Real Gas Mileage of the Chevrolet Malibu

Chevrolet Malibu Real Gas Mileage: Cons
Year	Comment
	The EPA rates the Malibu turbo 21 mpg city, 30 highway, below the Fusion 2.0T's 22/33 and the Sonata 2.0T's 22/34. The V6s in the Accord and Altima also do better?so much for the inherent fuel economy advantage of a turbocharged four over a V6. The trip computer confirmed the EPA ratings, with a little over 30 in straight 75 mph highway driving and anywhere from 19 to 27 in the suburbs depending on the frequency of reds and the heaviness of my right foot. Go with the traffic flow, and you'll split the difference at about 23. see full Chevrolet Malibu review

2014	4dr Sedan 196-horsepower 2.5L I4 6-speed shiftable automatic FWD	We are seeing beteer fuel economy over our 2009 Malibu w/2.5L 4-cyl engine. Just turned 5,000 miles & have gotten just under 34 MPG on hwy & 28 MPG around town. I expect this to improve, especially the hwy MPG. see full Chevrolet Malibu review
2013	4dr Sedan 182-horsepower 2.4L I4 Hybrid 6-speed shiftable automatic FWD	So far the dash display average is fluctuating between 37 and 40 mpg with mixed interstate (65%)/suburban (35%), "light accelerator foot," speed limit driving; at least 40% better than my prior V6 Toyota Solara. see full Chevrolet Malibu review

2011	4dr Sedan 169-horsepower 2.4L I4 6-speed shiftable automatic FWD	Good overall. Highway mpg can be 30-32 mpg. In city driving (stop and go) with short trips more like 18-19 mpg. see full Chevrolet Malibu review

2009	4dr Sedan 169-horsepower 2.4L I4 6-speed shiftable automatic FWD	Outstanding highway fuel economy. City fuel economy could be better but my driving is limited to fairly short distances with mostly stop and go. see full Chevrolet Malibu review

2007	4dr Crew Cab 5.5ft bed 315-horsepower 5.3L V8 4-speed automatic 4WD w/low range	Best in its class see full Chevrolet Silverado 1500 review
2006	4dr Crew Cab 5.5ft bed 295-horsepower 5.3L V8 4-speed automatic 4WD w/low range	With the specific gears I have in my truck, I get 20+ MPG on the highway...and I have a crew cab truck. City mileage is right in-line with the EPA of 14, but it is no worse than the others. see full Chevrolet Silverado 1500 review
2006	4dr Crew Cab 5.5ft bed 295-horsepower 5.3L V8 4-speed automatic RWD	Good for a pickup truck. see full Chevrolet Silverado 1500 review
2006	4dr Extended Cab 6.5ft bed 295-horsepower 5.3L V8 4-speed automatic RWD	The 5.3L gets an impressive 20mpg on the freeway and with a tonneau, about 21. Mixed driving is about 15-17mpg and purely city driving nets between 14-16mpg. Towing economy is not bad at about 12-13mpg with a light load and 9-11mpg with a heavy load. see full Chevrolet Silverado 1500 review

2004	4dr Crew Cab 5.5ft bed 295-horsepower 5.3L V8 4-speed automatic 4WD, part-time w/low range	Granted this is a truck but I did not like the fact that I was getting 14 mpg when the price of fuel was skyrocketing. This was never a good choice for fuel mileage. see full Chevrolet Silverado 1500 review
