Thursday morning's Formula 1 news roundup:

Black suit not reason for hot Bottas - Wolff

Toto Wolff has played down Valtteri Bottas' comments about his black racing suit for 2020.

As the Finn admitted in Barcelona that his championship hopes are "drifting away", he complained that he lost 3kg during the Spanish GP because his overalls are "f*****g hot".

Mercedes switched its car livery and driver suits to black for 2020 in deference to Lewis Hamilton's support for the Black Lives Matter movement.

But team boss Wolff denied that the colour change is Bottas' problem.

"We just have a new material," he told motorsport-total.com.

"Maybe we have to look again to see if we can find a compromise on how we can get it a little thinner."

Indeed, Bottas confirmed that more than just the racing suit's colour has changed for this season.

"There's a new homologation this year for the overalls, so they are thicker, and the underwear is thicker, so I don't know how much effect that has," he said.

FIA looking into legality of energy recovery systems

Formula 1 is looking into the legality of the engine manufacturers' 2020-spec energy recovery systems, according to Auto Motor und Sport.

The development follows the shock news in Barcelona last week that 'party mode' engine settings will be banned from Spa-Francorchamps, even though the precise wording of the technical directive is not yet known.

"What is certain is that all four engine manufacturers will have to upload detailed information about their ERS systems to the FIA server by August 21," said correspondent Michael Schmidt.

It is widely believed that Mercedes will lose the most because of the 'party mode' ban, but another manufacturer with strong engine usage settings in 2020 is Renault.

"There are several things connected with this ban," Renault boss Cyril Abiteboul admitted to Canal Plus.

"The FIA has more and more difficulties in this game of cat and mouse between the Federation and the teams. Anyone who enforces the rules must have enough data to be sure that everything is in compliance with the regulations," he added.
