F1 drivers want increased cockpit protection to be introduced no later than the 2017 season.
The FIA - in consultation with the Grand Prix Drivers' Association [GPDA] - has been investigating a number of different solutions to improve head protection, including closed cockpits. GPDA chairman Wurz says the research has highlighted the best way to progress which the drivers are in favour of being introduced as soon as possible.
"The research the FIA experts have done is very thorough and the process has brought forward a clear solution," Wurz told the BBC. "Now the drivers feel it's time to implement the extra protection at the latest in 2017."
Wurz says it is the 'halo' device (pictured) which has the drivers' backing, and says there is no excuse to it not being implemented next year.
"Obviously structural changes are required to the chassis but, with almost a one-year lead time, I don't see any technical person speaking against such substantial safety improvements, especially given the last big accidents in open-wheel racing involved head injuries.
"So all the drivers, and I, hope that passing the additional head protection will be a formality."
The topic will be discussed during a Technical Regulation Meeting in London on Friday, where the FIA hopes to also make progress regarding the 2017 regulations which are designed to produce faster and more aggressive-looking cars.
