Several teams have expressed their opposition to a proposed banning of wind tunnel use in Formula 1, suggesting it won't have the desired effect of driving down costs.

The debate over whether wind tunnels should be outlawed was again discussed during a Strategy Group meeting, but the topic again came up against opposition from teams who are unconvinced it would serve its intended purpose.

Indeed, though banning wind tunnels is being touted as a way to reduce costs in the sport with a view to placing greater emphasis on CFD, several figures have argued that the savings would be negligible given the investment in the technology made by several teams over the years and the potentially costly shift towards alternatives.

"We've actually done a deep analysis of the costs involved in running our tunnel and how much it would actually save if we closed it and the numbers correlate with the numbers that are currently in circulation at the moment," said deputy team principal Claire Williams. "It is minimal, the amount that you would save. Again, the compensatory elements... you would just save that money elsewhere as F1 teams, any cash that you would save somewhere, you would go and spend somewhere else."

Mercedes' Toto Wolff went on to add that the wind tunnel ban proposal raises a safety concern, forcing teams to get 'experimental' on the race track, rather than correlate developments away from it.

"We are a road car manufacturer and we have just commissioned a brand new wind tunnel in Stuttgart because a wind tunnel is needed today to put a car on the street, verify what's being done in CFD and to get correlation. It's a safety aspect and certainly Formula One shouldn't be the playground for funny experiments for opportunistic reasons."
