'100 per cent': Mercedes make huge call amid Lewis Hamilton contract talks

Lewis Hamilton will stay with Mercedes if Formula One's dominant team can provide him with the quickest car on the planet, Toto Wolff says.

Hamilton's STG40 million (A$77 million) per season contract with the Silver Arrows is up for renewal at the end of the year, and he has been linked with a move to Ferrari.

Team principal Wolff, who revealed he has not been in contact with Hamilton for two months, was speaking on Monday at London's Royal Automobile Club as Mercedes unveiled a new sponsorship deal with Sir Jim Ratcliffe's INEOS.

"We would like to have the fastest man in the car and I know Lewis wants to be in the fastest car so there is a mutual outcome," said Wolff.

"It is the obvious pairing going forward.

"We travel around the world for 10 months every year, and what we do over the winter is leave each other in peace.

"The last conversation that I had with Lewis was on the evening of the Christmas party and we agreed that we would continue our discussions when he comes back from America and we have properly kicked off the season.

"I have great belief in the ability of the team to attract the best drivers and, at the moment, Lewis has proven that he is the best current driver with his six world titles.

“I will give 100 per cent to make sure we have the best lineup in 2021. Lewis is the No 1 priority.

"In the mid and long term I would hope that we are able to provide technology to the best drivers and attract them to the team."

Mercedes’ future in Formula 1 uncertain

Hamilton, 35, is in London this week ahead of his first taste of the Mercedes he hopes will fire him to a record-equalling seventh world championship during a behind-closed-doors event at Silverstone on Friday.

The Briton's team unveiled their new livery for the forthcoming season which sported significant INEOS branding following the announcement of their five-year partnership.

Like Hamilton, Mercedes' future is also uncertain, with the German manufacturer yet to formally commit to the sport beyond this year.

"We like the Formula One platform but at the same time we are in negotiation with the rights' holder and things need to be sorted out," added Wolff.

"It is an ongoing process with a complicated set of contracts and that needs time. The devil is in the detail.

"Clearly, there is the will and the wish for all of the stakeholders to reach a conclusion before we embark on the 2021 season because that would be an uncomfortable situation.

"This partnership indicates the wish to continue our successful journey in Formula One.

“Mercedes provides a great marketing platform for our brand. This is what we do."

Mercedes' rivals Ferrari launch their new car in Italy on Tuesday, ahead of the first winter test in Barcelona next week. The season starts in Melbourne on March 15.
