F1 backmarkers HRT have denied suggestions that a company linked to Team Lotus - soon to be known as Caterham - are to build the monocoque for its 2012 car.

The team is currently working on the F112 as it seeks to build its own car in-house, although there have been suggestions that it was seeking to outsource some of the work to Caterham Technology and Innovation.

However, in a statement, HRT has downplayed that talk and says it will be building its third car alone and remains focused on being ready for the first pre-season test in February.

"After the recent information appearing lately in the media, HRT F1 Team is obliged to deny that Caterham Technology and Innovation, a subsidiary company of Caterham F1, will be in charge of the design and fabrication of the F112's monocoque," the statement read. "Contrary to what has been published, the development of the car that HRT F1 Team will compete with in next year's Formula 1 World Championship is being carried out at the team's technical office in Munich by a team of designers under the technical supervision of Jacky Eeckelaert and chief aerodynamicist Stephan Chosse.

"Despite the tight deadlines and a rule change for 2012 meaning that crash tests and chassis homologation procedures must be completed before any cars can test, the team is confident that the new car will be ready for preseason testing in February."

HRT is one of the teams yet to confirm a full driver line-up for 2012, having only announced Pedro de la Rosa thus far.
