F1 Raceweek: Mercedes rivalry rumbles on, Sauber sold


Back-to-back wins for Lewis Hamilton have piled the pressure on Mercedes team-mate and championship leader Nico Rosberg.

Here we take a look at what's been happening in the world of Formula One ahead of this weekend's trip to Hungary.

Best of enemies

It's a familiar tale. 

Mercedes duo Lewis Hamilton and Nico Rosberg have clashed on numerous occasions in the past, but relations appear particularly strained following a difficult few weeks for the German.

After footing the blame for a last-lap collision that cost him victory at the Austrian Grand Prix, Rosberg was demoted from second to third for breaking radio transmission rules as Lewis Hamilton once again claimed the win at Silverstone.

"I have huge respect for him [Hamilton] but, well, we're not best friends at the moment," Rosberg told The Guardian this week.

"We're just both so competitive and that makes it difficult to be friends because the competition is so extreme."

Rosberg's championship lead has been reduced to a single point and Hamilton unquestionably has the momentum heading to Hungary.

Changes afoot at Ferrari?

Reports in the Italian press suggest Ferrari could be on the brink of overhauling their management structure, with president Sergio Marchionne said to have taken over at Maranello.

The report in Gazzetta dello Sport claims technical chief James Allison could be on his way out after a "fracture" developed between the Englishman and the Ferrari hierarchy.

Allison is thought to be keen on a return to the United Kingdom following the death of his wife earlier in the season, with Toro Rosso's James Key tipped by Gazzetta as a potential replacement.

Sebastian Vettel and Kimi Raikkonen will remain in their seats for next season, but Ferrari's driver line-up beyond that is also up for debate.

Testing conditions

Pirelli have expressed a desire to see winter testing moved from Barcelona to the Middle East to ensure optimum conditions.

"We would prefer to go somewhere like Bahrain or Abu Dhabi," motorsport director Paul Hembery told F1's official website. 

"The temperatures will be representative and we know the tracks very well. We definitely would want to go to representative tracks."

Sauber sold

Sauber are to be acquired by investment firm Longbow Finance, with Peter Sauber retiring from all functions.

Successor as chairman Pascal Picci said: "As a Swiss company, we are very pleased with having secured the future of a Swiss presence in a highly specialised and innovative industry."
