Ross Brawn has stressed that Mercedes must improve their reliability ahead of the Bahrain Grand Prix.
Lewis Hamilton has claimed two podium finishes so far this season, but team-mate Nico Rosberg has twice retired courtesy of mechanical issues.
“The performances so far have been pleasing and perhaps even beyond our pre-season expectations however there is work to be done,” said Brawn.
“We must improve the reliability and we have to lift our performance to find that extra couple of tenths to our fastest competitors. A strong two car finish will be our target this weekend, and we want to see both Nico and Lewis in a position to score not only points but podiums regularly.”
“We’ve had a taste of success already this season and the slight feeling of disappointment with third place in China is our motivation.”
Hamilton believes the sandy track conditions could make for a challenging weekend.
“There are some areas where we need to improve to close that gap to the fastest cars and we’re working hard to identify and develop those,” he said.
“There’s a limit to what we can do before Bahrain but I’ll be talking to my engineers before we arrive at the circuit and seeing where we can improve in the short term. The Bahrain circuit is a real challenge, particularly for the tyres with overheating and also the sand on the track, but this helps to make it unique.”
