Nissan Juke-R (2011) first official pictures

Nissan has form for creating serious bonkers mash-ups – and the new Juke-R is the latest in a long-line of go-faster humdrum models.

Companies that do best at mixing technologies while keeping down costs will have an advantage when buyers wince at higher stickers.
