Formula 1👍 teams will be prevented from using screens to hide their cars from their rivals and fans during winter t൲esting, beginning from 2020.

The new rule is one of a number of changesไ a🥃greed to the 2020 technical and sporting regulations following Wednesday’s meeting of the FIA’s World Motor Sport Council.

In recent years teams have taken advantage of a lack of regulation regarding displaying their cars during winter testing to put covers on their new challengers or hide them completely behind large screens while pre-season testing tak🍨es place.

But the more stringent rules - which also apply during grand prix weekends - will stop teams being able to hide their cars, with the FIA explaining the move is to “make these events more appeal▨ing to the media and fans”.

Other changes approved by the FIA include reinstating the use🍃 of a physical che♑quered flag to end grand prix races.

A chequered light panel system has been used since an error at the 2018 Canadian Grand Prix led to celebrity guest Winnie Harlow waving the chequered flag a lap earlᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚy.

But a problem with the new electronic system led to the race distance at this year’s Japanese Grand Prix at🥀 Suzuka to be shortened by one lap, prompting a change for next season.

Tweaks to the rules regarding the sampling ꧅and testing of fuel at events have also been made, while the FIA has confirmed three standard suppliers from 202♔1 in line with its increased push to reduce costs of competing in the championship.

BBS will provide wheel rims, with Magneti Marelli producing fuel-priಞmer pumps and Bosch tasked with the responsibility of supply♓ing high pressure fuel pump and piping.
