For a subcompact, lightweight vehicle with an advanced engine and transmissions, the Juke's real-world gas mileage seems to fall short.
Startlingly low fuel efficiency may be something Juke owners need to judge before they buy. The EPA rates the Juke as high as 32 mpg highway, but in our experience, daily driving will yield results below even the city mileage of 24-27 mpg. We've logged about 24 mpg in a few Juke moves, and have seen 22 mpg or less from other publications. Those figures are low for a mid-size sedan, let alone a subcompact hatchback. Owner forums also log complaints of gas mileage in the low 20-mpg range, regardless of how the hatchback is driven.
Even before factoring in its performance and its sporty mission, the Juke's numbers are below average. Take for example the 2012 Hyundai Accent, a hatchback with an interior nearly large enough to qualify as a compact by EPA standards. It's rated at 30/40 mpg, with observed fuel economy of 33 mpg in our hands--and the same goes for the Veloster, the sporty four-door just introduced by Hyundai.
We've debated giving the Juke a green score lower than 7, but have given a little more standing to the EPA's official test numbers.
The Juke is not offered with any more fuel-efficient powertrains, such as a hybrid or a diesel.
