2017 Honda Clarity Fuel Cell: first drive of hydrogen-powered sedan

Note the acceleration of the Clarity – 0-60 mph in 9.2 seconds. As previously recorded in these pages, Toyota's Mirai does 0-60 mph in just under 10 seconds.1 Car & Driver recorded Hyundai’s Tucson fuel cell at 0-60 mph in 12.0 seconds!2

Take home message is, fuel cell cars have poor acceleration, & it’s fundamental to the way fuel cells work.1
