ADESS at the core of the H2 Speed project!

On Tuesday 6th March GreenGT and Pininfarina revealed the rolling chassis of the H2 Speed at the Geneva International Motor Show. ADESS, a partner in the project, supplied the carbon cell around which this electric-hydrogen fuel cell powered supercar is constructed.

The H2 Speed concept presented two years ago by GreenGT has now become a reality that was revealed at the 2018 Geneva International Motor Show. The prototype electric-hydrogen fuel cell-powered supercar designed by Pininfarina was on display on the Italian company’s stand. It is the first of a series of 12 cars destined for private clients for track use.

ADESS was entrusted with the design and construction of the carbon chassis of this exceptional car. It was developed on the basis of an LMP cell adapted to the particular specification of the project. The team of engineers and composite specialists took up this challenge in which they invested all their skills and enthusiasm.

“Accompanying such an avant-garde project in the world of the motor car is a major technical challenge,” explains engineer Stéphane Chosse, the ADESS general manager. “To design the chassis of a traditional high-performance vehicle whether it’s for racing or road use, we can call on tried and tested solutions that have proved themselves and were validated a long time ago in a known technical world. But the H2 Speed evolves in another dimension. Of course, it’s still a question of running the car as quickly and for as long as possible, but the constraints are completely new. An electric-hydrogen power unit does not present itself in the same way as, and does not behave like, an internal combustion engine. In fact, they have nothing in common with each other: not the dimensions, not the weight distribution, not the fluid circulation system, not the mechanical constraints. To get the best performance out of a car the installation of the power unit in the chassis must be flawless; and a perfect osmosis in the way they interact with each other must be achieved. The chassis is there, first of all, to give the power unit everything it needs to optimise what it, in turn, gives to the car by ensuring the lowest possible installation and the most efficient fuel feed and cooling systems. Then it must enable the power to be delivered in a constant manner and give the driver balance and precision in transition phases like braking, reacceleration, cornering, changes in grip etc. In all these domains we had to cope with new challenges imposed by the electric-hydrogen high-performance power unit. It’s because we were able to take them up that GreenGT and Pininfarina chose us. The fact that they recognised our fledgling company’s skills is a source of great satisfaction for our whole team.”
