The Honda FCX Clarity is a hydrogen fuel cell automobile manufactured by Honda. The design is based on the 2006 Honda FCX Concept. The FCX Clarity demonstrates electric car qualities such as zero emissions while offering 5 minute refueling times and long range in a full function large sedan. It was the first hydrogen fuel cell vehicle available to retail customers.[3]

Production began in June 2008 with leasing in the U.S. commenced in July 2008.[4] It was introduced in Japan in November 2008.

The vehicle’s electrical power comes from a 100 kW Honda Vertical Flow (V Flow) hydrogen fuel cell stack whereby electricity is supplied on demand. In common with many electric vehicles, the car has regenerative braking and uses a separate battery to store energy recovered during braking.

The electric motor is based on the motor used in the EV Plus, rated at 134 horsepower (100 kW) and 189 lb·ft (256 N·m) torque @0-3056 rpm. The range on a full hydrogen tank (4.1 kg @ 5000psi) is EPA certified at 240 miles (~386 km).[8] The vehicle is estimated to get about 77 miles (123.9 km) per kilogram hydrogen in the city, 67 miles (107.8 km) per kilogram highway and 72 miles (115.9 km) per kilogram in combined driving.[9]


The FCX Clarity was replaced in the Honda lineup with a new and higher-volume hydrogen fuel-cell vehicle introduced sometime next year.
