Nissan is set to unveil a new concept based on the existing NP300 Navara at the Hannover Motor Show tomorrow, but several photos have been accidentally leaked onto the internet. Most of them have been removed, except for the ones you see here.

Now, the one-off Nissan Navara Dark Sky concept features a decidedly rugged look, thanks to the new Porsche-esque four-point LED headlamps and bolder, full wide-body kit. The customised front bumper features a plastic brush guard and a winch, as well as a skid plate and illuminated red accents.

Round the side, the Navara concept gets a meaner stance courtesy of the extended fender flares, rock rails and huge wheels wrapped in off-road rubber. Other notable highlights include a roof rack, LED auxiliary lights and a unique modern livery that is presumably meant to resemble the night sky.

Its most distinctive feature though, is the custom-built trailer which is rumoured to be a “mobile space observatory.” Not much is known about it for now, but it certainly reflects the concept’s “Dark Sky” theme. Similarly, we don’t know what lurks underneath the bonnet here, but the standard Navara is powered by a 2.5 litre turbodiesel with 190 PS and 450 Nm of torque at 2,000 rpm.

The VGS Turbo oil burner is mated to a seven-speed automatic transmission with manual mode and a four-wheel drive system with on-the-fly mode switching. Lesser variants get a downtuned 2.5 litre diesel that makes 163 PS and 403 Nm. The Nissan Navara Dark Sky concept debuts tomorrow, so stay tuned.
