Wirth Research has confirmed a exclusive partnership with the Manor Grand Prix team to produce its Formula 1 car for 2010.
Formula 3 squad Manor was one of three new teams included on the FIA's entry list for next season, and former F1 chief designer Nick Wirth will be working on the new car.
The services will be provided by WR Technology Ltd as well as Wirth Research.
"Up until recently even my closest friends and family would have confirmed that I had no interest in making a return to designing Formula 1 cars," Wirth said.
"It's only with the exciting possibilities of cost constraints, with a refreshing new emphasis on design ingenuity and resource efficiency, that Formula 1 has now become a viable and fascinating new challenge for Wirth Research, and we will make sure it has all of the race-winning know-how that our previous cars have enjoyed.
"We see this project as a wonderful opportunity to demonstrate the quality of our work, increase our range of technology and engineering capacity to the benefit of all our existing and potential clients beyond Formula 1.
"As the project evolves, we hope to continue to demonstrate the benefits of our unique approach to Development in the Digital Domain."
Manor will be using Cosworth engines in 2010.
