Perhaps due to its tall, blocky shape, the 2012 Nissan Cube gets unimpressive ratings for highway fuel efficiency, though its city figures are competitive. The EPA rates the Cube at 27 mpg city, 31 mpg highway with the CVT, for a combined rating of 28 mpg.
That's a much narrower spread between city and highway figures than in most vehicles, and if anything, those ratings may be a tad optimistic. In quite rapid stop-and-go driving over a short test loop, our drivers saw just 24 and 25 mpg in two different Cubes fitted with the CVT.
Specify the six-speed manual transmission, and the mileage drops to 25 mpg city, 30 mpg highway, giving a combined 27 mpg rating--pretty low for a subcompact, even one with as much interior volume as the Cube offers.
