Following a preview earlier this month, Hyundai has unveiled the HDC-6 Neptune concept at the North American Commercial Vehicle Show in Atlanta.



Created to highlight the fact that Hyundai is “exploring opportunities” in the U.S. commercial vehicle market, the HDC-6 Neptune concept is a Class 8 heavy duty semi that runs on hydrogen.

Besides the eco-friendly powertrain, the concept features an Art Deco design that draws inspiration from streamliner railway trains from the 1930’s. In particular, the company noted the work of industrial designer Henry Dreyfuss who created eye-catching trains for the New York Central Railroad.

The front of the semi is dominated by a large windscreen which appears to flow into the cab. The semi has also been equipped with digital side mirrors which show images on a unique frame inside the cabin.

The Art Deco design isn’t just for looks as the lower ribbed section is actually a functional grille. It even incorporates retractable steps which are cleverly hidden and barely noticeable.

Hyundai didn’t mention performance specifications, but a press conference is scheduled for tomorrow. However, the company did say “fuel cells are the perfect fit for heavy duty trucks and long driving distances due to higher drive range, higher payload, less refueling time and ultimately lower costs.”

Besides showing off the HDC-6 Neptune, Hyundai also unveiled their Nitro ThermoTech trailer. Developed in collaboration with Air Liquide, the ThermoTech is a refrigerated trailer that uses a cryogenic nitrogen refrigeration system.

While that doesn’t sound too exciting, the company said the trailer cools quicker than a traditional refrigeration unit and is virtually noiseless. The trailer is also more eco-friendly and features “structural sandwich foam panels” that are covered by fiber reinforced polymer skins. Hyundai said the design increases wall strength and thermal efficiency, while also reducing weight.
