Force India's B-spec VJM08 impressed at Silverstone

Force India have told Sky Sports they are targeting fourth in the Constructors' Championship and have another upgrade package planned for the end of the summer.

The Silverstone-based squad debuted a B-spec car at the British GP, having essentially been running an updated version of their 2014 challenger during the opening rounds of the championship.

Deputy team principal Bob Fernley was delighted with the results of the new VJM08, describing its performance out of the box as "perfect" after both their drivers finished in the points. And having had their wind tunnel work verified, they will now press on with another development package.

"The new parts will start to be manufactured on Monday [June 6] because we obviously we couldn't do anything until we'd cleared it [the revised car] at the British GP," Fernley told Sky Sports. "Then it is just a case of when we can get it - hopefully we can get it for Spa, but if not Monza."

Fernley's faith in the new car is such that he feels Force India can record their best-ever result in the Constructors' Championship.

"We have to aim for fourth. Red Bull obviously are strong here, but there will be a lot of circuits going forward where we can outperform them," he said.

"We've got Hungary now to further develop this package and then hopefully we will add some more performance to it in Spa or Monza and that should see us through very competitive with Red Bull until the end of the season. I also think we have a better and more reliable power unit."

Force India's unique 'nostril' nose

Although both Nico Hulkenberg and Sergio Perez also finished in the points in Austria, Fernley feels repeating the feat at Silverstone would have been difficult had they still been running their old car.

"I think the key thing for us is we had optimised everything we could from A-spec in the last three races and we knew if we couldn't bring the B-spec in for Silverstone we’d be in trouble," he admitted.

"So it had to come in and more importantly it delivered."
