If you're wondering, this retro-looking semi-truck isn't from the set of a futuristic, dystopian movie or Robocop. In fact, it's an actual concept vehicle recently revealed by Hyundai called the HDC-6 Neptune. Unlike the commercial trucks of today, the HDC-6 Neptune will be hydrogen fuel cell-powered. At the same time, Hyundai says the hydrogen-powered truck previews the brand's future design language.

Despite being a peek into the future of Hyundai semi-trucks, the Korean automaker says that the design of the HDC-6 Neptune looks to the past for inspiration as well. In particular, the truck concept is inspired by design cues from the 1930s with the Art Deco streamliner railway trains.

This directly translates to the unique rounded shape of the truck and trailer. Large slatted grills that run the bottom half of the semi-truck help cool the system and hides the integrated stairs. More retro design can be found on the turbo-fan wheel covers.

However, not everything about the truck is retro-inspired. To give it a more futuristic look, large amounts of black glass is used in both the truck and the trailer. A blue LED strip then runs from the front glass and continues all the way to the trailer.

Inside, renders show a screen that wraps around the large curved windshield. Keen-eyed readers would notice that the steering wheel is still present. However, no pedals are visible. A heads-up display is mirrored onto the driver's seat. Interestingly, there are two captain's seats can swivel about in place of a more traditional bench seat.

For now, Hyundai has not yet provided any details regarding the HDC-6 Neptune's powertrain only saying it will be hydrogen fuel-cell powered. There's also no word as to when the hydrogen-powered truck concept will spawn a production model. Hopefully, though, we get to see a truck like the HDC-6 Neptune on the road in the future.
