Hispania Racing (HRT) and Dallara have announced that they are terminating their relationship after succeeding together in what many had reckoned to be 'an impossible task' and achieving 'more than could have been reasonably expected' against the odds to make the grid in time for the beginning of F1 2010.

Dallara was recruited by HRT's predecessor Campos Meta 1 to design and build the chassis for its maiden campaign of top flight competition, but after the Spanish outfit ran into financial difficulties, tools were downed in Italy and following the takeover by chief shareholder Jos? Ram?n Carabante, a desperate race against time ensued to make the curtain-raising Bahrain Grand Prix at Sakhir in mid-March.

Whilst that race was won, no testing was possible prior to the competitive action getting underway, and Hispania's early outings were a painful exercise in getting on top of their inevitable teething and reliability problems in the full public glare. What's more, the car has also proven to be invariably the slowest on the grid, and at times visibly quite a handful for F1 rookies Bruno Senna and Karun Chandhok. Through no particular fault of either party, it seems the end of the road has now been reached.

'Hispania Racing and Italian chassis manufacturer Dallara Automobili S.p.A have together agreed on amicable terms not to pursue their collaboration,' read an official HRT statement. 'The decision follows talks held over the last few months about the future of their collaboration.

'The two partners experienced a challenging start to the 2010 Formula 1 World Championship, where everyone at Dallara Automobili S.p.A worked extremely hard in a fight against time to be ready for the season-opener at the Bahrain International Circuit. Their persistent and determined efforts paid off as Hispania Racing pulled up to the starting line of the 2010 Formula 1 Gulf Air Bahrain Grand Prix ready to go.

'The whirlwind of pre-season activity at Dallara allowed the team, formerly known as Campos Meta 1 prior to its acquisition by Jos? Ram?n Carabante in February 2010, to meet its tight deadline. Since its inaugural race, Hispania Racing has completed six rounds of the 2010 Formula 1 World Championship, despite the fact that in all this time no further chassis development was made by Dallara.

'The collaboration, deemed by many to be an impossible task, resulted in the creation of the team's Cosworth V8-powered 2010 Formula 1 World Championship chassis, the F110, which was the very first car to be produced in the colours of Hispania Racing.

'Following the completion of six rounds of the 2010 Formula 1 World Championship, Hispania Racing and Dallara Automobili S.p.A have agreed that what they have achieved in such a short period of time was more than could have been reasonably expected. The two parties wish each other the best of luck in all future endeavours.

'Hispania Racing will continue to develop and improve the Dallara-designed F110 chassis via its own development programme. The details as to the outstanding terms of their business agreement remain confidential, and no further comment will be issued.'
