Renault team boss Eric Boullier has questioned plans to make F1 pit lanes all-electric from the 2014 season.
Under new regulations published by the FIA last week, cars will have to run on electric power while in the pit lane, with regulations stating that "the car must be run in electric mode (no ignition and no fuel supply to the engine) at all times when being driven in the pit lane".
While a number of 'green' ideas are being introduced in the coming seasons in an effort to make F1 more environmentally friendly, the issue of electric power in the pit lane has been questioned by a number of people in the paddock, with concerns for safety if people cannot hear cars moving in the pits.
"The concept is intriguing but... the cars would not make noise and that could be very dangerous," was quoted by Reuters
. "I think there are aspects of the rules published by the FIA which should be looked at again."
Boullier is also reported to have expressed a desire for an extra practice session to be brought in on F1 race weekends, as discussions continue about a return of in-season testing in some form from next season.
Currently, testing is banned during the season which leaves teams unable to test and develop new parts away from race weekends.
