Valtteri Bottas finished the Silverstone young driver test quickest as only two teams took to the track on the final day.
Friday's running took place on the shorter International Circuit and the Williams reserve driver, also fastest on day one, completed 170 laps setting a best time of 48.963 seconds.
Williams spent the morning testing a variety of aero parts, with a number of sensors on the rear of the car and an interesting tubing running from within a hole in the nose, down the pillars and across the front wing.
Marussia spent the day completing enough mileage to get Max Chilton and Rio Haryanto past the 300km mark of test time required to apply for their super licenses.
They did run some aero tests, however, with the car spending most of the morning covered in flow-vis paint.
HRT opted not to run on Friday, with Ma Qing Hua having returned home to China on Thursday night.
It brought to an end somewhat of a disappointing test, where it was originally thought nine teams would run.
Instead schedule changes and the uncertainty that surrounded the test due to a clash with a Formula Student event at Silverstone, left only Marussia, Williams and HRT running at the Northamptonshire venue.
Eight teams now look set to test in Abu Dhabi, as has become traditional, after the race there later in the season, with Ferrari rumoured to be eyeing a December date at Jerez.
