The regulatory modification (introduced by the CIK-FIA in December 2018) of article 2.14 (which regulates the safety procedures), letter Q, of the general provisions of the Sporting Regulations, which from that moment prescribed an absolute ban on "starting up, running in, warming up or testing the engines in the paddock and in the reserved areas..." definitely started the New-Line Racing project. If on the one hand this novelty has improved the general health and safety conditions in the paddock, on the other it has caused various problems in the correct setting up and use of engines, especially in the colder periods of the year. In fact, from the moment that mechanics could only start the engines in the pre-grid, when the marshals wave the green flag, thus forcing the drivers to enter the track with non-optimal engine and cooling system temperatures, with a non-negligible negative impact both on performance on the first laps and on the general reliability of the engines. To overcome these problems, various expedients were implemented, such as, for example, heating the water in the cooling system using simple boilers and then inserting it into the radiator. An ineffective solution given that, due to the dissipation effect, the temperature returns to room level within a few minutes with the radiator cold. Here then is the context in which the intuition of Marco Malverti materialized, owner of New-Line Racing together with Alberto Frigeri and Massimo Benedetti, who thought of designing special electric blankets for kart engine radiators and cylinders, so as to warm them up and keep them (together with the water inside the cooling circuit) in the correct operating temperature range. The production process faced by New-Line saw the development of a first prototype in the spring of 2022, in relation to which problems were encountered relating to the type of material used, polyester, which burned when the heating system of the electric blanket was switched on. This critical issue was resolved thanks to the collaboration with a specialised company (which also works with F1), which led to the development of a second perfectly functional prototype and, within a short time, to the approval of the final product, ready to be marketed.
