Marussia has confirmed that Max Chilton and Rio Haryanto will drive its car at this week's young driver test at Silverstone.
With three teams electing to take part in the post-British GP test that takes place on Thursday and Friday - Williams and HRT are also running - the test is going to be divided between a day on the grand prix track and a day on the International circuit.
Chilton has previous F1 experience with Force India from last year's young driver test in Abu Dhabi, while Haryanto did half a day for the then Virgin team back in 2010.
Marussia will run Chilton on the first morning and the final afternoon, with Haryanto driving on the Thursday afternoon and Friday morning.
Williams will run its test driver Valtteri Bottas for both days, while HRT will hand a first F1 chance to Chinese driver Ma Qing Hua.
