Though not officially announced yet, the Hyundai i-Blue Concept will debut at the Frankfurt Motor Show next month, according to Automotive News. The i-Blue Concept is a hydrogen-powered exercise in being green and practical at the same time. It uses Hyundai's third-generation hydrogen fuel cell. While past Hyundai hydrogen concepts were SUVs, the i-Blue mirrors the trend of the day by sitting atop a new car-based crossover platform. No more news is available on the i-Blue Concept since Hyundai hasn't officially announced it yet. We don't know where Automotive News got the above image, and we're interested since the i-Blue may contain future Hyundai styling cues. Look for those on the vehicle's front end, as that giant C- and D-pillar combination at the vehicle's rear would make for one hellish blind spot on a production vehicle.
