Apr.17 (GMM) Paul Hembery has rubbished suggestions Lotus and Ferrari are getting an unfair advantage in 2013.
One theory doing the rounds is that Lotus' E21 is kind to the otherwise heavily-degrading tyres this year because Pirelli's test car is the 2010-spec R30 -- which was designed by Enstone based Lotus' former incarnation, Renault.
He confirmed reports that rival teams rejected a proposal to share the burden of providing Pirelli with a test car.
"We even proposed that they alternate with each other to test our tyres, but none of our proposals proved popular," said Briton Hembery.
"So they can't start complaining now."
Hembery also rejected a wild theory that Ferrari obtained an advantage through the shared nationality of its lead driver, Fernando Alonso, and main Pirelli tester Jaime Alguersuari.
He smiled: "Someone told me actually that Jaime and Fernando don't even talk.
"Anyway, how could a comment be converted into a design?" he wondered. "That's hard to accomplish.
"And even if you could get something from it, it would be pretty minimal."
