Oneof the best ways to increase the enginećs power is to skillfully design theair- supply system of the engine. This is the reason why the first part of the paper is about the intake-manifold optimization procedure. The procedure relies on mathematical programming and offers a way to significantly increase the engine power in the most important engine regimes. In the second part of the paper, attention is focused on new concepts of building the racing car. Inorder to be the best it is necessary to do more than symply follow the competion. An analysis of the positions of the main components has shown that a racing car would be more agile and stable if the engine was to be mounted beside the driver. Optimizing the intake manifold represents one significant step forward in the struggle to increase the effective power of the car, whichbrings an immediate advantage. The new position concept, however, which also eliminates the differential drive, represents a completely new development in the design of the Formula S car that might bring us long-term benefitsV prispevku sta prikazani dve moznosti izboljšanja lastnosti dirkalnika Formula S. Eden najskladnejsih načinov za dvig moči motorja je spretno oblikovan dovod zraka v motor. Zato je v prvem delu prispevka predstavljen postopek optimalnega oblikovanja sesalnega sistema. Postopek optimiranja temelji na uporabi metod matematičnega programiranja in pomeni učinkovit način za povečanje moči motorja v najbolj zanimivem področju obratovanja motorja. V drugem delu prispevka je pozornost posvečena novim zamislim izdelave celotnega dirkalnika. Za dosego vrhunskih rezultatov je treba narediti več, kakor le slediti konkurenci. Analiza postavitev glavnih agregatov je pokazala, da bi k večji okretnosti in stabilnosti dirkalnika pripomoglo to, da bi bil motor postavljen ob voznikovi strani. Optimiran sesalni sistem pomeni zanesljiv korak naprej v borbi za povečanje dejanske moči dirkalnika, kar je lahko uporabno takoj. Zasnova z bočno postavitvijo motorja pa predstavlja povsem novo pot razvoja dirkalnikov Formula S, kar bo morda prineslo dolgoročne prednostiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
