Porsche have denied claims that recent high level technical acquisitions could lead to a potential F1 return in the future.
A year ago the German sports-car maker denied it's new Le Mans project, which will see Mark Webber behind the wheel in 2014, was a mere warmup for an F1 return.
Alongside Webber, Porsche have also signed multiple F1 engineers including Fritz Enzinger, Alex Hitzinger, Mike Krack and Urs Kuratle.
Their facility in Weissach has been upgraded to allow world class motor-sport operations to take place complete with a wind tunnel.
Correspondent for Germany's Auto Sport und Motor Tobias Gruner has suggested the arrival of the F1 engineers could be "on the prospect of a Formula One comeback" in the near future.
A spokesman for Porsche denied the speculation insisting the VW-linked carmaker was "fully committed" to it's Le Mans project as well as GT racing.
"There are no plans to enter Formula One," the spokesman added.
However, comments in a recent Porsche employee magazine could suggest otherwise.
The article says that because F1 is returning to V6 turbo engines in 2014, Porsche has contacted Hans Mezger, who was key to developing McLaren's TAG-Porsche turbo units back in the 1980's.
"This (magazine) article was surprising, to say the least," said Gruner.
In a separate report by Gruner in Auto Sport und Motor he has revealed the FIA is in a race against time to ensure it can control the fuel rate of the 2014 V6 turbos next season..
Gruner revealed a British company called Gill HySpeed was given the contract by the FIA for the new sensors but was disappointed by results gathered at the young driver test in June.
"The result was worrying," Gruner revealed. "Instead of the maximum permitted deviation of 0.5 per cent for the specified flow rate, the error (margin) was actually up to 1.5 per cent."
Gill HySpeed is now working to fix the issue however if the solution is deemed insufficient then the FIA would have to rely on data coming from the three engine makers, Mercedes, Renault and Ferrari.
With the solution expected soon, it is understood further testing will be undertaken either at Pirelli's tyre test with McLaren in Vallelunga or in a Friday practice session as "bench testing alone is not enough".
If the results are upto standard the sensors will then be issued to the teams prior to the first pre-season test next year.
