Force India's much-anticipated B-spec car will not be at next week's in-season test in Austria.
The team have been waiting for their updated model to arrive since the start of the season and it is expected to run at the British Grand Prix in a fortnight.
However, the team had planned to run it in the two-day test, which follows on from this weekend's Austrian Grand Prix.
Driver Sergio Perez told reporters: "We're going to have it for Silverstone. We're obviously doing some testing with some of the parts of the new spec but the main upgrade will come to Silverstone.
"It's definitely very good news as it's only one race left. Hopefully we can score points this weekend then aim for a much better second half of the year with the upgraded car."
Force India are currently seventh in the constructors' standings.
