The Formula One teams are unsurprisingly at loggerheads over the destiny of this season's young driver test.
An event traditionally seen as an ideal opportunity to put future F1 stars through their paces has for the last two years occurred immediately after the Abu Dhabi Grand Prix late in the season.
This year, however, there has been talk of it taking place in the days following the British Grand Prix in July, both for financial and logistical reasons.
The argument against, though, is many of the drivers who would be tested are in the middle of their own campaigns such as GP2, GP3 or Formula Two, and therefore cannot properly be assessed.
At present there is a definite split as to preference, with some teams favouring Abu Dhabi and some Silverstone, but common ground needs to be found as only one venue can be used.
Toro Rosso technical director Giorgio Ascanelli feels a test at Silverstone would cost the team a considerable sum.
Ascanelli said: "We were counting on the fact the young driver test would occur at the end of the year so we could sustain it with the engine mileage left over from the races.
"A second test in the middle of the season, which wasn't planned, for us, is half a million (euros)? We don't have it."
Ascanelli is supported by Red Bull and McLaren, with the former's technical director Adrian Newey reasoning: "I would have thought you are best off evaluating young drivers at the end of a season.
"They're not in a junior formula they've been competing in, they have finished their championship, you can see how they've gone and they've a bit more experience.
"To drop them into a Formula One car in the middle of the season and then hoof them out again and tell them to wait another eight months before they can drive it again, I'm not sure of the value of that."
McLaren sporting director Sam Michael added: "I've exactly the same view as Giorgio and Adrian.
"Our plan at McLaren at the moment is to test in Abu Dhabi. We're not testing at Silverstone for the reasons mentioned.
"Engines is a significant factor. If you want to test at the end of the year, you have so many part-mileage engines with the race team that all have a little bit of mileage on them so you can effectively do it for free.
"If you try and do that in the middle of the year, you can't use your race engines so you have to prepare a special test engine."
For the likes of Caterham and Sauber, however, their preference is Silverstone.
Sauber's head of vehicle performance Pierre Wache said: "For us it's quite different.
"The better compromise in terms of cost would be to test at Silverstone for plenty of reasons: for logistics and costs."
Caterham technical director Mark Smith concurred, adding: "It's the same for us - logistically and cost-wise, Silverstone sits better for us."
