Audi prin\u00e1\u0161a \u010fal\u0161iu zauj\u00edmavos\u0165 o svojom s\u00fa\u0165a\u017enom prototype R18 e-tron quattro. Od roku 1999 neboli tak\u00e9 pr\u00edsne pravidl\u00e1 ako tento rok a aut\u00e1 neboli tak prepracovan\u00e9, ako s\u00fa dnes.<\/p>\n

Do nov\u00fdch pravidiel bola zaraden\u00e1 aj nov\u00e1 hodnota\u00a0suchej hmotnosti vozidla z\u00a0 900 kg na 850kg. Kon\u0161trukt\u00e9ri mohli preto siahnu\u0165 po nov\u00fdch materi\u00e1loch (pevnej\u0161\u00edch a \u013eah\u0161\u00edch) a samozrejme do\u0161lo aj ku zmene kon\u0161trukcie cel\u00e9ho auta a jeho okapotovania (vr\u00e1tane aerodynamick\u00fdch prvkov). Audi R18 e-tron quattro v minulom roku malo skvel\u00fdch 915kg. Ak sa v\u00e1m toto \u010d\u00edslo zd\u00e1 pri tak ve\u013ekom mon\u0161tre \u00fa\u017easn\u00e9, tak zadr\u017ete dych pri hmotnosti R18 e-tron quattro 2014. Je to 870kg (skoro ako motorka s kuframi). \u010co teda vyhodili, aby z\u00edskali rozdiel 45kilogramov?<\/p>\n

Pod\u013ea pravidiel (ale tak \u010fakujme\u00a0im za pokrok) je pr\u00edsnej\u0161ie bran\u00e1 bezpe\u010dnos\u0165 v n\u00e1razoch zo str\u00e1n. Preto sa zmenila kon\u0161trukcia posledn\u00e9ho st\u013apika, toho ktor\u00fd je spojen\u00fd so zadn\u00fdm kr\u00eddlom. Tento nov\u00fd Zetkov\u00fd st\u013apik zvy\u0161uje celkov\u00fa tuhos\u0165 auta, pardon, superpreracovan\u00e9ho prototypu a t\u00fdm je mo\u017en\u00e9 ubra\u0165 z hr\u00fabky kon\u0161trukcie na in\u00fdch miestach = zn\u00ed\u017ei\u0165 celkov\u00fa hmotnos\u0165 pozemnej st\u00edha\u010dky.
\n\u010eal\u0161ia oholen\u00e1 \u010das\u0165 je monokok (hahaha pri slovenskom n\u00e1zve, ale je to jednoliata kab\u00edna vodi\u010da), ktor\u00fd je pevnej\u0161\u00ed a \u013eah\u0161\u00ed a samozrejme m\u00e1 u\u017e aj in\u00e9 rozmery.

Namiesto pudingu pou\u017eili al\u00a0CFRP.

Pravidlo prevodov: po starom sa prip\u00fa\u0161\u0165ali prevodovky so \u0161iestimi stup\u0148ami (nie Celzia) dopredu. Po novom\u00a0je dovolen\u00fdch (\u010di prik\u00e1zan\u00fdch? – kto sa m\u00e1 vyzna\u0165 v t\u00fdch Franc\u00fazoch a ich pravidl\u00e1ch) 7 prevodov\u00fdch stup\u0148ov dopredu. No a okrem zmeny prevodov\u00fdch pomerov (to je to aby auto ne\u0161lo ako Pionier, na dovjke trhal rekordy a na trojke trhal nervy, preto\u017ee ne\u0161iel) sa zmenila celkov\u00e1 hmotnos\u0165 prevodovky na v\u00e1he o viac ako\u00a020kg smerom dole.<\/p>\n

Z CFRP je napr\u00edklad aj volant (teda jeho jadro) a in\u00e9 prvky. Dokonca sa d\u00e1 z CFRP vyrobi\u0165 aj pru\u017eenie, konkr\u00e9tne pru\u017einy pre podvozok.
