There is more bad news for Force India fans with the team admitting their new car is unlikely to run at the next test.
The Silverstone squad are absent from the opening pre-season test at Jerez after revealing that the VJM08 is not yet ready to hit the track, but they were hoping to launch the car ahead of the second test, which takes place at Barcelona from 19 February.
However, deputy team principal Bob Fernley has now conceded that their new challenger will in all likelihood only be ready for the final test in Barcelona from February 26.
"Given the workload and timescales involved, it's now looking more difficult to make the first Barcelona test," he told Autosport.
"Everybody is pushing to try to make it happen, but it's far more likely the VJM08 will run at the final Barcelona test at the end of February.
"That means we will use the 2014 car at the next test. The mileage on the VJM07 will still allow us to run with the 2015 Pirelli compounds."
There have been reports in recent days that Force India could miss the season-opening race in Australia on 15 March, but Fernley insists that is not the case.
"We will be in Melbourne for the start of the season, there's no doubt about that," he said.
"Yes, testing time with the new car will have been limited, but we are doing everything possible to make sure we arrive in Australia in reasonable shape and with as many miles on the car as possible."
