GCK Performance

Prototypes and small series

With nearly 15 years of perfecting race cars down to the last detail, the word “optimize” has become deeply embedded in GCK Performance’s DNA. Today, the company applies the same methods to design, manufacture and develop vehicles with a wide range of functions.

Motor sport

For nearly 15 years, GCK Performance has been designing, manufacturing, developing and operating successful racing cars on all types of terrain (asphalt, dirt, ice, sand). This activity calls on all the company’s skills, from the design office, through the workshop, to logistics and deployment in the field. We use this expertise to bring our customers to their highest level of performance.

  • Lancia Delta Evo-e RX, the first retrofitted race car in history to compete in an FIA World RX Championship round.


Created in 2020, the GCK group offers a 360° approach combining the development of technologies for tomorrow’s mobility, their integration into vehicles and the supply of clean energy. Its mastery of all powertrain components (engine, battery, fuel cell, VCU) enables GCK Performance to manufacture all types of prototypes running on electric or hydrogen, thus promoting the energy transition.



GCK Performance designed and manufactured the first three examples of the Lancia Delta Evo-e, which were used for the development, homologation and industrialisation of this iconic model retrofitted with electric power, 47 of which will be marketed by the company Special ONE.

Automotive equipment manufacturer

Equipment manufacturers ask GCK Performance to set up prototypes or demonstrators capable of testing or reporting on the functioning of a concept, a component or a product.

Having designed and manufactured these special vehicles, our team knows them inside out and is often selected by the client to carry out their test programme. In this respect, the fact that the Charade site belongs to the GCK group is an undeniable asset in the success of this type of campaign.





In order to improve the thermal management of on-board batteries in electric vehicles, Motul and GCK Battery are developing an immersion battery technology that they can test in our prototype (built on a “vintage” Lancia Delta base) allowing for rapid fluid replacement.

Offroad (military, forestry)

With its experience in off-road racing, GCK Performance designs and develops different types of light and strong off-road vehicles, which combine ingenuity and efficiency. Our SSVs, ATVs or UTVs are capable of evolving on terrain inaccessible to conventional 4×4s and of moving quickly with equipment. They can carry systems or tools that are cleverly integrated into the chassis design.

  • ATV (all-terrain vehicle) an uncovered, all-terrain vehicle, single or two-seater.
  • SSV (side-by-side vehicle) an all-terrain vehicle in which the occupants sit next to each other.
  • UTV (utility vehicle) an off-road vehicle with a rear dump body used to transport various materials and equipment.

Restoration and renovation

Restoring a vintage car involves the same attention to detail as building a modern race car. It also requires the use of techniques with which GCK Performance is familiar, such as reverse engineering using a 3D scanner. It is therefore quite natural that our teams took up this challenge with a youngtimer well known to the French…





In the 1980s, international rallies were dominated by the monstrous Group B cars, including the Peugeot 205 Turbo 16. A whole generation of young people dreamed of competition, without necessarily having the means to do so. And then the 205 GTI arrived… Quite an act. The GCK Performance teams paid tribute to it by resurrecting a model with more than 95% new parts, in compliance with the specifications for the restoration of historic vehicles. The result – sublime – of this first, will certainly call for others…
