Audi H-Tron Concept is a familiar face now with hydrogen power

Audi shows its green side at the 2016 Detroit Auto Show with the H-Tron Concept, a hydrogen-fueled version of the recent E-Tron Quattro concept. The new fuel-cell powertrain gives the futuristic crossover an estimated range of 372.8 miles on the European cycle, and the company claims that the solar panel that spans the roof could let drivers recoup 621 miles of range each year from the sun’s rays.
