The best V6 minivans are best known for their confident power, and even as the 2016 Nissan Quest delivers on that front, engineers also have squeezed a bit more fuel economy from its 3.5 - liter V6: After revisions to the Quest's X-tronic continuously variable transmission, its EPA
rating in combined travels
bumps up 1 mile per gallon to 23 mpg; unchanged are its 20 mpg city / 27 mpg highway numbers, but Nissan now ranks No. 1 in the segment for both city and combined fuel
efficiency.
The 2.5 - liter four - cylinder saw a 9 - hp power
bump and increased fuel
efficiency for an EPA fuel - economy
rating of 25 mpg in the city and 35 mpg on the highway with the six - speed automatic transmission.
