Lamborghini Essenza SCV12 - full carbon chassis homologated according to the FIA standards
The Lamborghini Essenza SCV12 is the first car on the market with a carbon fiber roll cage homologated according to the FIA Hypercar safety standards. This extraordinary achievement is the result of Automobili Lamborghini’s thirty years of experience in the study and application of composite materials in the automotive field.
The carbon fiber chassis of Essenza SCV12 are produced in the autoclaves of Automobili Lamborghini’s CFK Department in Sant’Agata Bolognese, a division of excellence that also produces the chassis of the current Aventador line.
The testing required by the Fédération Internationale de l’Automobile for chassis homologation is extremely rigorous, involving both static and dynamic tests. The Lamborghini Squadra Corse technicians thus extensively modified the structure of the production chassis from which the Essenza SCV12 chassis is derived.
The carbon fiber monocoque was reinforced in several points, having to withstand forces of over 12 tons during the FIA homologation tests without presenting significant deformations. There are more than 20 static tests which, in addition to the chassis, involve the pedals, belts and fuel tank. The dynamic crash tests, on the other hand, involve impacts at speeds of up to 14 meters/second. In this type of test, the chassis must not be subjected to any intrusion of external elements that could come into contact with the driver, and the fuel tank must not leak.
The decision of the Lamborghini Squadra Corse technicians to maintain the carbon fiber structure, i.e. not mounting a steel roll cage, allowed not only a benefit in terms of overall weight, thanks to the use of innovative laminated foams inside the chassis (ROHACELL® 71 XT), but also provided a significant increase in cockpit space for optimal driving comfort.
In the Essenza SCV12, the driver sits on an OMP FIA 8862 homologated seat, mounted on carbon fiber cradles designed by Squadra Corse and produced in Lamborghini’s CFK laboratories. The seat has been lowered compared to the road models and the driver and passenger are protected on the door side by two side impact guards, also made of composite material, which replace the classic steel tubes found in racing cars.
Another new solution is the cradle situated in the rear part of the monocoque, which houses the engine perfectly positioned on the longitudinal axis, while the gearbox has a load-bearing and structural function. This characteristic also made it possible to achieve torsional stiffness values 20% higher than those of the Huracán GT3 EVO.
The first units of Lamborghini Essenza SCV12 were delivered to customers in April 2021, and the dedicated program of track events will start at the end of June.
