GM Sequel concept rear

GM's hydrogen dreams inch closer to reality with this Sequel, which they claim as the "sequel to the first 100 years of the automobile" (and also serve as the sequel to its Autonomy and Hy-wire concepts). About the size of a Cadillac SRX, the Sequel proves nearly as useful thanks to its 5-passenger capcity, 300-mile range and 0-60 time of under 10 seconds. The 8 kilogram capacity of its hydrogen tank and a lithium-ion battery are partly to thank. With the real-world drivability issues solved, affordability is the only remaining obstacle.
