Recent rumors suggested Audi would show off a hydrogen-powered version of its E-Tron concept at this week’s 2016 Detroit Auto Show. Those rumors turned out to be correct, as the Audi H-Tron Quattro concept made its debut today in Detroit.

Visually, the H-Tron looks nearly identical to the E-Tron. The most obvious change is its bright yellow paint job and five-spoke wheels. The concept is expected to preview an upcoming Q6 crossover, which will sit between the new Q7 and the Q5 (a second-gen Q5 has been confirmed to debut sometime this year).

Audi CEO Rupert Stadler introduced the hydrogen-powered concept, but not before mentioning the diesel exhaust crisis currently affecting the Volkswagen Group. Stadler said the crisis provides a “unique opportunity for change and innovation.”
