The Super Aguri team looks set to push for a change to be made to the regulations for the 2007 Formula One season which would mean teams being forced to sideline one of its race drivers for the Friday of a Grand Prix weekend.

Under rules coming into force next season, the use of a third car for the Friday practice sessions will be forbidden, although teams will still be allowed to run three drivers in its two race cars for the pair of 90 minute sessions.

However, under the new rules, teams running three drivers could be left at a disadvantage against those who just give race drivers time behind the wheel – as one team would effectively be sacrificing track time for one of its main drivers to give a tester a chance.

With that in mind, Super Aguri managing director Daniele Audetto admitted that the newest team in the paddock, with only a season of F1 racing under its belt, would be looking to change the rules to leave teams giving track time on a Friday to just one race driver so as not to disadvantage the smaller teams wishing to run a young test driver – a driver in some cases who may well bring extra revenue to the team as has been the case on occasions in the past.

"We are looking to the next Formula One commission meeting to ask the other teams to make it compulsory to have a test driver on Friday," he told Reuters. "Otherwise, with only two cars available, I will not give an advantage by running a test driver to other teams that will be using their regular drivers.

"If you use a young test driver [on Friday], you will be less competitive for setting up the car and therefore the qualifying and the race. So either everybody uses a third driver on Friday and that must be compulsory - that one of the regular drivers must not drive at least for one session of 90 minutes - or I think very few teams will give a chance to a test driver on Friday.

"We have to wait and see if a test driver is important or not next year.”

Such a move would require the unanimous agreement of all the teams on the grid, although it remains to be seen whether the front runners – such as Ferrari, Renault and McLaren – would be prepared to have one of its big name race drivers sitting twiddling his thumbs rather than carrying out vital work ahead of the weekend.

Super Aguri has yet to name a test driver for the 2007 season, with race drivers Takuma Sato and Anthony Davidson the only people signed to contracts for the new campaign.
