Renault admitted that Lotus is likely to start the 2014 season off at a disadvantage since they won't attend the year's first pre-season test at Jerez.
Earlier this month, Lotus Principal Eric Boullier confirmed that the Enstone team will miss the season's first official testing session and on Wednesday, Renault's deputy managing director (technical) Rob White admitted that the F1 outfit will probably be a "a little bit behind the game" because of it.
"I guess the first thing to say is that the fundamental power unit is identical between the four teams who use our power unit," White said.
"But of course each installation is unique and the objectives for the first test or two are to fully validate the power unit in its environment; it's absolutely the first time that you can bring the whole thing together and turn it on.
"You haven't got the chassis environment at the factory. Obviously we do a great deal to try to simulate as much as we can, but we haven't ever - ahead of the fire-up - brought together every single little piece, sub-system and system, in the exact configuration it will be in that car.
"So the stuff that is shareable and shared between the teams is the stuff that pertains directly to the power unit, not the stuff that pertains to its particular environment. So there's no additional burden on anybody that runs in Jerez relative to anybody that doesn't run in Jerez, it's more that anybody that isn't able to run in Jerez will be a little bit behind the game and that includes the power unit side of the equation."
