F1 teams want quick decision on 2023 changes

Formula One teams say they need a quick decision, preferably before the August break, on proposed 2023 technical changes that aim to end the sport's 'porpoising' problem but have divided the paddock.

The governing FIA wants to tackle vertical oscillation, a phenomenon where cars bounce at speed like a porpoise through water.

The problem is a consequence of this year's major aerodynamic changes.

The plan is to raise the floor edges of cars by 25mm and perform more stringent lateral floor deflection tests.

Some teams, such as Ferrari and Red Bull, who do not have a problem with porpoising argue that the proposals favour those who got this year wrong and should not be forced through on safety grounds.

Either way, all need to know what rules apply for 2023 to avoid wasting precious time and resources under the cost cap, with new car development and design ramping up after August.

"It's not yet too late, but we can't afford waiting another four or six weeks," said Alfa Romeo technical director Jan Monchaux.

"I would prefer those changes will be for '24 but if it comes for '23, I think now just before the (August) shutdown is kind of the latest that is acceptable."

Mercedes trackside engineering director Andrew Shovlin said his team wanted clarity.

"Are they going to change? If so, let's get on with it and agree it," he said.

"We know as a team we need to fix our problems ourselves and we set that as an objective from day one and we're pretty confident that we can achieve that objective. So that's why I said for us, the big thing is we just want clarity on it."

McLaren's James Key said "the sooner we know the final numbers, the better."

Red Bull principal Christian Horner earlier pointed the finger at Mercedes, suggesting the changes were "so a certain team can run its car lower and benefit from that concept".

Mercedes have particularly suffered from porpoising and are yet to win a race after taking the constructors' title for eight years in a row, but they appear to be getting on top of the problem now.

"You can understand the conundrum of teams that don't want the regulations to change. We don't know, as Mercedes, that a regulation change will suit us," said Shovlin.

"Our stance would be that if we want to solve some of the fundamental issues, you're not going to do that leaving the rules alone."

Chechnya leader makes Mo Salah honorary citizen

Chechnya leader Ramzan Kadyrov has made Egypt’s talismanic striker Mohamed Salah an honorary citizen of the southern Russian region at a farewell banquet held for the eliminated World Cup side. Rights groups and Western governments allege that authorities in Chechnya repress their political opponents, discriminate against women and persecute sexual minorities, all allegations that Chechnya’s leaders deny. Chechnya has been hosting the Egyptian team’s World Cup training camp and Kremlin-backed Kadyrov has seized on opportunities to appear alongside Salah. Sarah’s goalscoring exploits for Liverpool and Egypt have made him an international superstar. “Mohamed Salah is an honorary citizen of the Chechen Republic. “Yes, that’s right! Tonight I signed a decree conferring this high award on the great footballer and member of the Egypt and Liverpool teams,” Kadyrov wrote on Telegram. Salah was presented with a badge and a copy of the decree at the dinner, Kadyrov said. The Egy...

Oil prices rise amidst uncertainty over Libyan crude exports

Oil prices rose, Tuesday on uncertainty over Libyan oil exports, although plans by producer cartel OPEC to raise output loom. Brent sweet crude futures, the international benchmark for oil prices, were at 74.95 dollars per barrel at 01.04 GMT, up 22 cents, or 0.3 per cent from their last close. The United States West Texas Intermediate (WTI) crude futures were at 68.33 dollars a barrel, up 25 cents, or 0.4 per cent. Traders said prices were mostly driven higher by uncertainty around oil exports by Libya, a member of the Organisation of the Petroleum Exporting Countries (OPEC). Eastern Libyan commander, Khalifa Haftar’s forces have handed control of oil ports to a separate National Oil Corporation (NOC) based in the East of the country. The official state-owned oil company based in the capital Tripoli, also called NOC, will not be allowed to handle that oil anymore, he said. In comments later confirmed to the media, Ahmed Mismari, spokesman of Haftar’s Libya National Army...
