23 June, 2022, Goodwood Festival of Speed. Pioneering cleantech engineers, Viritech debuted their revolutionary hydrogen powertrain technology in the form of the Apricale, the world’s first zero-emission hypercar to achieve weight parity with petrol-engined competitors, at the Goodwood Festival of Speed today.

Performance with Purpose

Apricale is the first car in the world to achieve zero-emissions hypercar performance, with a weight of only 1,000kg. This transforms the driving experience of the Apricale. it combines the agility of the best petrol-engined hypercars with the instant response of an electric motor. Indeed, the electric drivetrain means it is actually more responsive than a traditional hypercar.

However, the Apricale does more than simply transform the electric hypercar. With the combination of a light weight and zero emissions, it opens up a new world of sustainable transport. Many vehicles cannot function with a powertrain that weighs more than an equivalent internal combustion engine. Until now, such vehicle categories have been excluded from the move to zero-emissions powertrains, as batteries are always heavier than internal combustion engines – and the higher the power requirement, the bigger the difference.

Silvio Angori, CEO of Pininfarina describes the design as ‘a synthesis of technology, sustainability, beauty, and above all, performance.’

The powertrain of the Apricale represents a historic landmark. It proves that a zero-emissions powertrain can offer the same power, the same weight and the same range as an internal combustion engine.

Re-imaging FCEV

The ambition to overcome all the compromises of zero-emission vehicles required Viritech’s engineers to completely reconsider how fuel cells and batteries function together. Matt Faulks, Viritech’s CTO explains, “Hydrogen fuel cells have, until now, been used as range extenders for powertrains with batteries at their heart. We’ve essentially turned that approach on its head, developing a powertrain around multi-hundred kW fuel cell system supported by a lightweight but highly efficient battery. This delivers hypercar performance for Apricale, but at less than half the weight of typical BEV hypercars.”

Faulks continues, “Not only does this reduction in weight transform Apricale’s driving dynamics, but our reduced reliance on batteries means less demand on rare earth minerals.”

The multi-hundred kW fuel cells are combined with unique Ultra High Power lithium-ion cells developed by technical partners, AMTE Power and Viritech’s patent-pending intelligent energy management system, Tri-Volt™. While the fuel cells provide the main motive power for Apricale, the battery provides additional power for acceleration and ultra-high performance driving, as well as a highly-efficient storage for regenerative braking energy.

The Tri-Volt™ Energy Management System and Viritech’s patent-pending power electronics enable a continuously variable mix of energy from both the fuel cells and the batteries. In addition, the very fast charge and discharge batteries enable the regenerative braking system to recover many times more kinetic energy than a traditional battery electric vehicle.

Until now, hydrogen has been another key weight problem. To withstand the700 bar pressure, most hydrogen storage tanks have a weight efficiency of only around 5% (ie 5kg of hydrogen requires a 100kg storage tank). Viritech’s engineers developed a radical solution. Viritech’s patent pending Graph-Pro™ technology uses lightweight composites and a graphene-enabled resin system, allowing the tanks to form part of the structural element of the Apricale monocoque. This solution minimises weight, improves packaging and provides a projected range of over 350 miles/560 kms before refuelling.

The Chassis, Unshackled

The fact that Apricale weighs only 1,000kg means that it can escape the handling constraints of a BEV hypercar. The suspension features all-round pull-rod torsion bar suspension with a limited degree of active ride control. With a low polar moment of inertia, the car will have the dynamic characteristics of a classic mid-engined supercar with minimal weight transfer under steer, yaw and pitch.

There are two drive motors (one on the front axle, one on the rear). With its sub-1,000kg weight, there is limited requirement for torque vectoring, so the driveline uses a pair of mechanical differentials.

The unique combination of light weight and the instant response of electric motors means that the Apricale will be even more inspiring to drive than a traditional supercar.

Matt Faulks, Viritech CTO said "Apricale has enabled us to completely reassess the benefits that different energy vectors offer. Until now, engineering choices have been finite and compromised, but adding hydrogen into the mix offers a whole new array of capabilities that we have aimed to optimise with a new approach to FCEV. Apricale is going to be spectacularly exciting for its owners and we truly hope marks a new chapter in powertrain technology. It is great to see that vision realised at Goodwood today."

 

Future Technology fused with Timeless Design

The Apricale revealed at Goodwood today was originally conceived as a reference design by Viritech, and optimised by Pininfarina.

Silvio Angori, CEO of Pininfarina describes the design as ‘a synthesis of technology, sustainability, beauty, and above all, performance.’ Viritech is extremely proud of working with perhaps the greatest name in automotive design, a partnership which embodies the Apricale’s mission to take the heritage of the hypercar, and completely reinvent it for the future.

Alongside the development of the Apricale’s styling, Viritech is in discussion with Pininfarina to build the limited production run of just 25 examples at its atelier in Cambiano in Turin.

With stunning looks, Apricale will not just be seen, but also heard. Matt Faulks explains that ‘cars must be imbued with personality’ and to that end, Apricale will have its very own distinct and futuristic sound emanating from the fuel cells and electric drivetrain.

 

Delivered in 2024

Apricale’s key technologies including the drivetrain, the Tri-Volt™ EMS and the Graph-Pro™ structural storage vessels have already been validated in two mule vehicles that have successfully undergone testing. Experimental prototype 1 (XP1) will provide the final sign-off process for the powertrain. While XP1 will test for 100,000km, it will overlap with a production prototype, intended to validate all aspects of Apricale during 2023, so that Viritech can commence customer deliveries in early 2024.

Timothy Lyons, Viritech's Founder said "Viritech is focused on becoming the world's leading developer of hydrogen powertrain solutions and the Apricale, with its requirement to optimise weight, space and performance, provided us the perfect development platform for our core powertrain technologies, which have also been designed for broad application in the coming age of sustainable transportation"

 

Scalable Technology

The technologies developed by Viritech are highly scalable. Viritech focused on the Apricale for their first application since a hypercar platform makes the most significant demands of power, weight and packaging. Proven in Apricale, the powertrain technology is being developed by Viritech for a diverse range of sustainable transport applications. ​

Matt Faulks, Viritech’s CTO said, “Apricale has enabled us to completely reassess the benefits that different energy vectors offer. Until now, engineering choices have been finite and compromised, but adding hydrogen into the mix offers a whole new array of capabilities that we have aimed to optimise with a new approach to FCEV.
