The production version of the Pininfarina H2 Speed debuted at the 2018 Geneva Motor Show.

The concept version originally debuted at the 2016 Geneva Motor Show, and later that year, the Italian coachbuilder confirmed it would be heading to production. Only a dozen units of the hydrogen race car will be produced, powered by four electric motors that are good for a total system output of 653 horsepower. Helping make the production car a reality is Pininfarina’s partner, GreenGT, which is a Franco-Swiss company that has been designing, developing, and manufacturing clean and sustainable propulsion systems since 2008. Some of the components used in the production H2 Speed from GreenGT include the 250 kW fuel cell and torque vectoring system.

The H2 Speed features an LMP carbon fiber-based chassis with a steel frame. There’s a direct transmission to the rear wheels, which means no clutch, no differential, and no gear shifting. With the bodywork, it weighs about 3,130 pounds (1,420 kilograms), allowing it to hit 62 mph from a standstill in 3.4 seconds. Top speed is set at 186 mph (300 km/h). For dry conditions, the race car is equipped with Michelin Pilot Sport GT 59M tires, while Pilot Sport GT P2L rubber is available for wet conditions.

As you can expect, the interior is fairly basic since it is a race car, after all. The dash is covered with black Alcantara andĀ features all the instrumentation in the center. The seats have been designed and created by Sabelt, with the seat belts being the same units provided by Sabelt to the Formula 1 teams.

Pricing was not officially announced, but reports say Pininfarina executives suggested it would cost around $2.5-million.
