The Manor Formula 1 team says it has kicked off its 2015 development programme thanks to Roberto Merhi completing a race distance in the Malaysian Grand Prix.
Manor has used an updated version of the 2014 Marussia car in the first two events, although the car did not turn a wheel in Australia and only Merhi took part in qualifying and in the race at Sepang.
Teammate Will Stevens was unable to run after final practice following a fuel system problem.
Merhi completed the race, although he finished three laps down.
Team boss John Booth said the running has helped Manor begin a development programme.
He said: "Thanks to our first full race distance at Sepang, we've been able to use the data gathered there to get our 2015 development programme underway and we're looking forward to applying what we have learned from that in the field this weekend."
The team has retained both Merhi and Stevens for this weekend's Chinese Grand Prix.
Manor has stated it plans to unveil a 2015 car at some point during the season.
