Manor team principal John Booth says the team is aiming to have its 2015 Formula 1 car ready for the summer break in August.
The team has been running a 2014-spec car, which has been modified to meet this year's regulations, after it was successfully revived at the eleventh hour having gone into administration last season.
Booth said once the first four flyaway grands prix are out of the way the team will work through a plan for the introduction of the 2015 car.
"For the 2015 car, our aim has always been for the August break," said Booth.
"As with arriving in Australia, it is a very aggressive target and will take a lot of achieving.
"But when we get back from these first four flyaway races we just really need to sit down and see if we can bring all the areas together that need bringing together to achieve that in that timeframe."
Nine of the season's 19 grands prix take place after the summer break.
After failing to get either car running in Australia and only managing to get Roberto Merhi's car functioning for the race in Malaysia, Manor achieved its first double finish in China last weekend.
"That was a major step forward for us," Booth said.
"We ran every session on plan and operationally we're working as we were last year."
