Force India are a step closer to racing their B-spec car after the chassis passed its mandatory FIA crash tests.

Off the pace this season after a delayed start to pre-season testing, Force India's hopes for their 2015 season are resting on a revised car.

The car's debut has been pushed back on several occasions not helped by the fact that it failed one of the crash tests in May.

However, the good news for Nico Hulkenberg and Sergio Perez is that the chassis has now passed all the tests and is on course to be raced at the British GP.

Deputy team principal Bob Fernley told Autosport: "We failed the first test, but it was pretty marginal.

"In the end it was tiny, and although it put us back a week or two, it was pretty clear we would get through the second one.

"There are a lot of elements to it, but it has passed all the tests necessary to go forward.

"We'll now make it for the test in Austria, and then we will introduce it as a race package for the British Grand Prix at Silverstone."

He added: "Considering the enormity of the changes, it's quite a credit to them to be able to get it through at the second attempt.

"I always had great faith in them, and our engineers as a whole, so congratulations to them on doing a great job on that."
