Nissan has long proclaimed the Juke-R to be the world’s fastest crossover, much to the chagrin of automakers like Porsche and BMW, who build fast crossovers (and SUVs) that you can actually buy instead of just watch on video.

That said, it’s hard to argue with the performance numbers put out by Nissan and reported by World Car Fans. The Juke-R can sprint from 0 to 60 mph in just 3.7 seconds, on its way to a top speed of 160 mph.

Just for reference, the BMW X6 M takes another 0.6 seconds to hit 60 mph, and it’s governed to a top speed of 155 mph. The Porsche Cayenne Turbo takes 4.6 seconds to hit the mile-per-minute mark, but it does have a top speed (on the track, of course) of 172 miles per hour.

We’ve been pretty clear that the Juke-R is an engineering exercise that will be used for promotions and motorsports only and will never see the inside of a Nissan showroom. Judging from some of the questions submitted by fans on Facebook, this hasn’t been well communicated.

Just to be clear, if Nissan did build the Juke-R, its cost would be so prohibitive that they’d never sell a single unit. It would probably be less expensive (though infinitely more complex) to build your own from a crashed GT-R and a donor Juke.

We’d bet that project would still run the cost of a new Porsche 911 by the time all was said and done, and we’d much rather have the reliable production car (with the full warranty). We admire the Juke-R for what it is, but also fully understand what it isn’t.
