The EPA hasn't yet published the official gas mileage numbers for the 2013 Nissan Quest, but with no mechanical changes, it's expected to carry over last year's figures. Those put it on roughly equal footing with the top-selling minivans, especially now that the Toyota Sienna is losing its four-cylinder engine option.
The Quest doesn't fare as well as some minivans on the highway side of the cycle. Its V-6 engine is coupled only to a CVT, and the duo was rated at 24 miles per gallon on the highway cycle for the 2012 model year. The Honda Odyssey earns 28 mpg on the highway in its most expensive, six-speed-automatic version; Chrysler's minivans and the related VW Routan get 25 mpg highway.
However, for city mileage, the Quest is a leader. Its 19 miles per gallon on the city cycle equals the Sienna and the Odyssey, while Chrysler's minivans check in significantly lower.
No hybrid or diesel editions of the Quest are planned.
