At the 2016 Geneva Motor Show Pininfarina has brought the H2 Speed, a hydrogen-powered high performance race car developed in partnership with GreenGT.


With its H2 Speed, Pininfarina is embracing a growing trend for combining environmental-friendly powertrain with a focus on high performances and driving fun.

The latest concept from the Italian studio is powered by a 503 horsepower hydrogen fuel cell powertrain, and was developed in collaboration with GreenGT, a Franco-Swiss company which has been designing, developing and producing clean propulsion systems since 2008.

As Pininfarina reports the H2 Speed is “halfway between a racing prototype and a production supercar” and could anticipate an exclusive limited edition car for collectors.

The exterior design of the H2 Speed combines two main themes: aerodynamic efficiency and pure beauty.

The overall look includes the traditional styling cues of sports cars: low, aggressive proportions, strong design and an emotional synergy between car and driver.

At the same time the car needed to be adapted for the GreenGT Full Power Hydrogen system, so all parts of the layout have been designed for the correct distribution of weights and for optimal power transfer.

The main performances are a 0 to 100 km/h sprint time of 3.4 seconds and a top speed of 300 km/h, and an additional highlight is the rapid refueling: refilling a full tank of hydrogen takes 3 minutes.

Pininfarina H2 Speed Concept: the design

The main dimensions are length of  4,700 mm, a height of 1,087 mm, a width of 2,000 mm and a long wheelbase of 2,900 mm.

One of the main design constraints was the need for two large hydrogen tanks at the sides of the vehicle.

In order to avoid weighing down the side of the vehicle, the hydrogen cylinders are faired instead of being incorporated into the body volume but they remain visible through a window in the rear part of the fairing where the fuel cap is easy to access.

Arising from the marked sidecut, the three-dimensionality can be seen also in the plan lines of the vehicle. The geometric composition of the design from above seems to consist of two triangular bodies that intersect to generate the front and rear mudguards.

The intersection between these two volumes defines the features of the plan, side and perspective views, playing seemingly on a symmetrical drawing.

The crests of the mudguards do not follow wing volume in a traditional way but enter and exit the body, giving sensuality and originality to the handling of the surfaces. Modeling the side panel makes it possible to hollow out a generous air passage from front to side.

The result is an efficient aerodynamic flow and, at the same time, the creation of three-dimensional hollowed out volumes that leave part of the carbon frame visible as well as mechanical parts like the suspension arms. At the entrance to these channels, the two big front radiators located laterally, cool the entire fuel cell block. At the front, between the two radiators, a center duct permits the flow of fresh air which, channelled along the sides of the cabin, cools the engine compartment.

The muzzle presents two upside-down L-shaped wings which direct the aerodynamic flows and also act as supports for the lighting system: the apparently suspended led strips give the front an attractively original, dynamic expression.

The volume of the cabin is a transparent, tapered, aerodynamic drop shape characterized by a body-colored band extending over the windshield. Its two ribs integrate roll bar volumes and house an air intake that feeds the compressor intercoolers.

A vertical fin on the hood channels flows to the rear; a big spoiler anchored to the fin creates negative lift and downforce to handle the power generated by the electric motor. Also on the bonnet, two air intakes for the radiators are designed to cool the electric motor.

The cut-off rear volume is cleanly detached from the flows and is characterized by sloping mudguard volumes; playing with the sidecut in plan view, the mudguards confer its original shape on the tail volume, directly deriving from technical and aerodynamic needs.

At the center of the transom a fine, horizontal lighting strip, elegant and basic, integrates lighting functions typical of high performance cars.

Inspiration from the 1969 Sigma Grand Prix

The choice of body color is inspired by the Sigma Grand Prix and gives it a modern interpretation with a plain pearlescent shade of white.

As in the Sigma, the addition of fluorescent touches in vermilion and acid yellow highlight the functional areas: the aerodynamic tip of the front, the aerodynamic scoop, the edge of the centre fin, the spoiler fins, the windows that leave the side hydrogen tanks visible, as well as the technical details on the wheel hubs and the brake calipers.

Again inspired by the Sigma and racing cars in general, the safety controls and lights/transmitters and the hydrogen filler cap are highlighted in a purely functionalist way. The great functional and technical surfaces (front wings, tank bodies, spoiler, extractor and all the car’s aerodynamic features) are in anthracite grey.

The H2 Speed logo and graphics are a modern tribute to the styling of the Sigma Grand Prix and as in that iconic car of ’69, the presence on the sides of the Swiss flag, associated here with that of Italy, represents a symbolic celebration of the renewed alliance between a Swiss company (GreenGT) and Pininfarina.
