Green GT and Pininfarina unveiled a joint vision for the future of endurance racing at the 2016 Geneva Motorshow. The H2 Speed is based around Green GT’s hydrogen-electric powertrain, which has been under development since 2008.
The car is built around a 210kW PEMFC fuel cell and two electric synchronous motors with permanent magnets that have a peak output of 370kW at 13000rpm. These are complimented by a 20Ah battery, which forms part of the car’s kinetic energy recovery system.
The power from the hydrogen-electric powertrain is transferred directly to the rear wheels via a fixed 1:6.3 gear ratio. This is enough to propel the 1420kg car to 100km/h in a claimed 3.4s, and on to a top speed in excess of 300km/h. Also notable within the H2 Speeds spec list is the rapid refueling ability: A full tank of hydrogen can be done in just three minutes.
The powertrain is housed within an all carbon chassis, which features double-wishbone and pushrod suspension all-round, carbon brakes, and a carbon-fiber body. On track testing of the car begins soon, with test and development responsibilities falling to Olivier Panis.
