At low speeds the FCHV can run on battery alone, with a range of about 50 km (31.1 mi). For high performance, such as when accelerating from rest, the fuel cell and battery supply power in tandem. The battery can also charge by regenerative braking, improving overall efficiency. There are currently five generations of the FCHV, beginning with preliminary prototypes FCHV-1 (1997) and FCHV-2 (1999). The FCHV-3 was presented at the "International Symposium on Fuel-Cell Vehicles" in March 2001 in Tokyo

, and the FCHV-4 was the first production version, although Toyota do not plan a full-scale commercial hydrogen fuel cell vehicle launch until 2015.

As of 2008 the FCHV-adv was available for lease in Japan . The use of the vehicles by government ministries and companies is intended to provide detailed development feedback on the FCHV performance under varied driving conditions.

In 2007 a FCHV was driven 560 km (348 mi) between Osaka and Tokyo on a single tank of hydrogen, proving that a hydrogen vehicle could compete with conventional vehicles for range. In August 2009, Toyota USA announced an estimated FCHV-adv range of 690 km (428.7 mi) from a 6 kg (13 lb) tank of hydrogen, based on a 331.5 miles (533.5 km) test trip in "real-world" conditions between Torrance
