I think Jordan aren’t comparable to Williams, as this level of technology is much more advanced, and thus much more marketable than 20 years ago.
The further difference is that Williams is a company, as much as a race team. It sells it’s technology on to others. It’s KERS system for example and the new Jaguar that is being built in conjunction with the Tata owned company.
So I think they will be around for a while, but they certainly need results. Obviously Sam Michael is stepping down at the end of this year, which is a shame, but it’s hard to see what else they could have done.
