Dec.21 (GMM) F1 cars will feature 1980-style 'tea tray' front wings in 2013, the BBC reported on Tuesday.

With KERS and adjustable rear wings to feature on the grid next season, and radical 4-cylinder turbo engines to debut in 2013, the report said the new front wings are the next significant change for formula one in two years.

To replace the big and wide front wings of today, the 2013 cars will reportedly generate the bulk of their downforce underneath the car, with the formula drawn up by veteran engineers Patrick Head and Rory Byrne.

The teams will receive the draft 2013 regulations - which will also see the cars wearing much smaller rear wings - this week before they are discussed in detail by the Technical Working Group in January.

"(In 2013) We are only going to have roughly 65 per cent of the amount of fuel and a (limited) fuel (flow) rate -- that was a given," Head, engineering boss and co-owner at Williams, confirmed.

"We were just told 'That's what it will be, you've got to come up with a car spec that is not going to be more than five seconds a lap slower than a current F1 car'.

"So some circuit simulation was done by Rory at Ferrari and when we'd come up with some numbers in terms of drag and downforce it was then to try to come up with a geometry of a car that could try to achieve that," he added.
