Force India switches to blade roll hoop
8 February 2011 – Following in the footsteps of Mercedes GP from 2010, Force India has taken the same route as Team Lotus by introducing a blade-style roll hoop on its 2011 car, the VJM04. Technical Director Andrew Green explains its significance.
Green – who rejoined the Silverstone squad last July - replaces Mark Smith as the head designer at Force India, with the former coming back to the team after designing its first ever car – the Jordan 191 – exactly 20 years ago.
“Everything is different, but visually a lot of it is subtle,” he explains.
“The most obvious visual change is that we've gone away from a conventional roll hoop to a blade. This gives us a small packaging improvement compared to a more conventional style.
“The engine cover is different, in-line with the abolition of the f-duct system, but there are a lot of differences under the skin that people won't necessarily notice.
“We've recovered a lot of the aerodynamic performance, we believe. We still have a little bit to go, but we are still in the process of the realignment after the end of last season because it does take a long time to move aerodynamically from one position to another.”
