Variable geometry intake manifold and first aero package – “Road Arrow 2014” can brag with the most significant innovations up to that time. Variable geometry of the intake manifold was alive as an idea throughout the entire 2013 season. Finally, solution for the only dilemma left in designing such a system, students found on the Ferrari model that they saw in the museum near Riccardo Paletti circuit, after the competition in Italy.

After a year of work the team finished variable geometry intake manifold with two servomotors that varied longitude of the intake runners, manufactured with 3D printer. Although the maximum engine power was reduced, the team got more balanced engine’s work so the overall performance of the vehicle was improved. Also, in the same year the first aero package was presented, made out of glass fibers. Even though the “Road Arrow 2014” got the wings, it had 18 kilograms lower mass than the previous one.
