While the EPA rates the 2013 Juke at up to 32 mpg highway and 27 mpg city (in front-drive, CVT trim), the manual model scores just 25/31 mpg and the all-wheel-drive Juke rates 25/30 mpg.
In our real-world experience with the Juke, we've seen average figures around 24-27 mpg in daily driving. That's well below the 27-29 mpg combined EPA rating, and not particularly strong performance for a subcompact with a 1.6-liter turbo four-cylinder engine.
The Juke is, however, somewhat sporty, with 188 horsepower and a willingness to run free. Still, taken against competition like the Hyundai Accent (30/40 mpg city/highway) or the Ford Focus (28/38 mpg) the Juke falls short.
