Presentata la nuova Citroen DS3 R3

La Citroen Racing, vincitrice di 5 titoli Costruttore nel WRC, ha presentato oggi al pubblico la nuova Citroen DS3 R3 che debutterà ufficialmente verso la fine del 2010. Versatile, performante e con un prezzo accessibile, la DS3 R3 è destinata a divenire il nuovo leader della categoria.

La nuova Citroen DS3 R3 è costruita secondo il regolamento FIA per le Gruppo R3T, ha la stessa struttura delle vetture di serie, con la struttura dell’abitacolo rinforzata e rollbar multipoint. Sotto il cofano c’è un 4 cilindri di 1.6 litri THP ( turbo ad alta pressione ) che è stato sviuppato sulla base del propulsore PSA. Tutto è stato scelto con accuratezza per far arrivare la vettura ad una potenza di 210bhp. In aggiunta alla potenza massima è stata posta particolare attenzione alla coppia per migliorare la trazione, ben 350Nm.

La DS3 R3 vanta tutta l’esperienza della Citroen nel WRC, come la Citroen C4 WRC è equipaggiata con un cambio a sei rapporti semi automatico con controllo sequenziale, che permette di cambiare marca due volte piu’ velocemente di un cambio manuale.

Il sistema di sospensioni usa la piu’ recente tecnologia ed è stato costruito per adattarsi a tutte le superfici stradali, dalla terra all’asfalto. C’è un’ampia varietà di setup predefiniti, che rendono la Citroen DS3 R3 adatta a tutti gli stili di guida. La Citroen Racing raccomanda di montare gomme BFGoodrich sulla Citroen DS3 R3.

La Citroen Racing parla di prezzo accessibile per questa vettura, ma non ci sono ancora informazioni precise in merito.
