Obviously the springs themselves are not “smart”, but are made with a… smart material, in this case a metal alloy with shape memory effect. That is, after suffering a deformation (stretching), these springs manage to return to their original shape, as if nothing had happened.
They are one of the parts of the LSMS or Lamborghini Smart Material System, an intriguing system debuted in the Sian FKP 37 and Sian Roadster , which helps extract the heat accumulated in the compartment of the massive 6.5 V12 with 785 hp.
Intriguing because the four articulated flaps (flaps) that open and close via the “smart springs” do not need electronically operated electric or hydraulic actuators to function, being a fully autonomous system.
What makes them stretch or contract is just the temperature in the V12 compartment. That is, when the temperature reaches a certain value, the chemical structure of the springs changes and they stretch, opening the flaps. As the temperature drops, the springs return to their initial state and the flaps close.
