Lewis Hamilton has denied reports he was considering leaving Formula One, as the seven-time Drivers Champion looks to bounce back from the controversial finale to the 2021 season.

Hamilton was beaten by Red Bull's Max Verstappen in a contentious conclusion to the Abu Dhabi Grand Prix, after race director Michael Masi elected to allow a series of cars to pass a late safety car, permitting one lap of racing with the Dutchman on new tyres.

Masi has since been removed from his role, while rumours abounded that Hamilton could leave the sport. But, speaking at the launch of Mercedes' new W13 car, Hamilton denied that his return was ever in question.

"I never, ever said that I was going to stop", he said. "I love doing what I do, and it is such a privilege working with this large group of people.

"You really feel like you're part of a team and part of a family, working towards that common goal. There's no feeling quite like it.

"But yeah...it was obviously a difficult time for me, and it was a time where I really needed to take a step back and focus on being present."

Mercedes boss Toto Wolff had previously hinted that Hamilton was left 'disillusioned' by finishing second, but the 37-year-old now claims to be focused on making a successful start to the 2022 season next month.

He also expressed his excitement at working with new teammate George Russell, who has replaced Valtteri Bottas after leaving Williams in the off-season.

"I eventually got to a point where I decided I was going to be attacking, coming into another season working with Toto and George," he added.

"It's exciting seeing George come in and bring his energy. I can already feel that throughout the team. I think it's going to be an exciting season."

The launch of the W13 sees the German constructor return to its classic silver livery after two years using a black colourway, as part of an anti-racism campaign, and the car has been advertised by Mercedes as '98 per cent new' and as 'the product of a complete redesign from top to bottom'.

With the team bidding for a ninth consecutive Constructors' Championship title, Hamilton is keen to ensure standards remain high.

He said: "Naturally, every single individual within this team has worked towards the ultimate goal of winning the world championship, raising the bar and doing something that no one else has done before."

Toto Wolff has told of Lewis Hamilton's hurt at the contentious nature of his Formula One title failure but hopes the seven-time world champion will not quit the sport.

Hamilton looked to have done enough to beat Max Verstappen to the championship on Sunday, leading with one lap of the Abu Dhabi Grand Prix – and the season – remaining.

Despite Verstappen's pole, Hamilton had forged ahead in just the second F1 title race to see the top two level on points heading into the final grand prix of the year.

But race director Michael Masi made a controversial call to let the cars between Hamilton and Verstappen – running first and second but separated by a series of lapped rivals – pass a late safety car and allow one lap of racing.

Verstappen, on fresher tyres, passed Hamilton to secure his first title, becoming the first driver ever to win the championship by passing his direct rival on the final lap of the season.

Mercedes launched a double protest of the result, which was dismissed, and then appealed, before finally accepting Verstappen's triumph on Thursday.

Team principal Wolff confirmed to reporters Hamilton had played a part in those decisions, having seen a contentious finale put a huge dampener on another historic season in which he became the first man to both 100 F1 poles and a century of race wins.

Could that painful final chapter in 2021 put Hamilton off returning in 2022 for another tilt at the outright F1 championship record? For now, he remains tied with Michael Schumacher on seven titles.

"I would very much hope that Lewis continues racing, because he's the greatest driver of all times," Wolff said.

"When you look at it from the point of view of the last four races, he dominated them. On Sunday, there wasn't even a doubt who won the race. And that was worthy of winning the world championship."

He added: "It is going to take a long time for us to digest what has happened on Sunday. I don't think we will ever get over it. That's not possible – and certainly not as a driver."

Despite Mercedes' protests, Wolff said they had not wanted "to win a world championship in the courtroom".

Having initially kept his counsel as the team went through the appeal process, Wolff on Thursday accused Masi of a "freestyle reading of the rules" that "left Lewis like a sitting duck".

The Silver Arrows at least had the consolation of an eighth constructors' championship – all of which have come in the past eight seasons. For 2022, George Russell will replace Valtteri Bottas.

New Formula 1 world champion Max Verstappen has revealed he was graciously congratulated by both Lewis Hamilton and Mercedes team boss Toto Wolff following Sunday's Abu Dhabi Grand Prix triumph.

The Dutchman ripped his first-ever world championship from Hamilton's grasp after overtaking the Briton on the final lap in Abu Dhabi after a controversial late-race safety car period.

Mercedes protested twice about the circumstances around Verstappen's triumph after Hamilton appeared to be coasting to victory with an 11-second lead with 10 laps to go.

Despite that, Red Bull driver Verstappen said that Hamilton and Wolff had been gracious in defeat.

"Toto sent me a text - congratulations on the season and that I deserved to win, that was very nice," Verstappen said.

Verstappen added: "Lewis is a great sportsman in general."

He continued: "Of course it helps if you have already seven titles," Verstappen said. "That comforts him a bit. I think if it was the other way around, it would have been more painful for me because I didn't have one.

"Lewis came up to me and congratulated me. It must have been very tough in that last lap. It also shows the respect we have for each other.

"Of course we had our tough times through the season but we respect what we're doing and we were pushing each other to the limit and it has been very enjoyable racing against him."

Meanwhile, a message aired via car on-board channels has surfaced with Hamilton claiming on radio message "this has been manipulated" with four corners to go when trailing Verstappen on the final lap.

Hamilton made the remark to race engineer Peter Bonnington, angered by Race Control's handling of the safety car restart with only the five lapped cars between the seven-time world champion and Verstappen permitted to be overtaken, allowing the Dutchman a clear run in the final lap.

Ex-Formula One supremo Bernie Ecclestone has accused Mercedes of looking like bad losers in the aftermath of the controversial ending to the Abu Dhabi Grand Prix that saw Lewis Hamilton pipped to the title by Max Verstappen.

An immense battle for the drivers' championship concluded in the most dramatic of circumstances on Sunday with Verstappen passing Hamilton on the final lap after the safety car had been deployed.

With the two neck-and-neck heading into the season finale, it looked as though Hamilton would retain his title having built up a healthy advantage over his rival.

However, there was a late twist when the Williams of Nicholas Latifi crashed into the barriers four laps from the end, with Verstappen pitting for fresh tyres as the wreckage was cleared in order to try to get a shot at Hamilton.

Such an opportunity presented itself when race director Michael Masi controversially ruled lapped cars could overtake the safety car before it headed in to leave one last lap of racing between the contenders.

It was Verstappen who proved triumphant, with Mercedes left furious with Masi, who told Mercedes team boss Toto Wolff: "We went car racing."

Amid Red Bull's celebrations, Mercedes lodged two complaints, claiming Verstappen had overtaken Hamilton before the safety car had pitted and opposing Masi's decision to allow the lapped cars to pass.

Ruling body the FIA dismissed both challenges, but Mercedes could yet appeal against the second of those.

Ecclestone said Mercedes ought to let the issue rest.

Speaking to Stats Perform, he said: "It's always been the same. The funny thing is the winners laugh and the losers have to make their own arrangements, and that's how it is. 

"It's no good being a bad loser. I'm sorry to say, the problem at the moment is Mercedes look a little bit like that, which is not what they are like and they shouldn't even make it look as if they are bad losers. 

"In the end what happened, if you really want to analyse it properly, you can say the world championship came down to one lap. It was the last lap of the race where two guys were on the track with nobody there. In fact, Lewis was a little bit lucky as he started that lap before Max, but in the mean, they were there racing each other, and Max came out in front. 

"Nobody should really, really complain. I don't know whether people did complain at the beginning where Lewis got a little bit of an advantage when he went past Max not on the track, and Max was actually on the track. I thought there was going to be some sort of a reprimand about that. 

"Nothing happened, which is okay. They should get rid of all the silly regulations in Formula One. 'Don't go over the white line, don't do this and don't do that', and when the lights go off, the guys are racing on their own, and they're racing."

Ecclestone added that he had no issue with the decision made by Masi.

"A couple of times this year I've thought that the race director was a bit stupid with one or two things he did, when he had plenty of time to think," he said.

"But in this case, I would have no complaints at all because he was there with a few seconds to make up his mind what to do and it took four hours of Mercedes' team with a lawyer to decide who was right and who was wrong. 

"It's difficult to say that the race director should take four hours to do the same thing. Even then, they haven't come back with the right decision, according to the stewards, so we'll have to wait and see. 

"You need a race director and you need one person to be in charge, and if the person isn't doing a good job over a period of six months or whatever, then get rid of him.

"But that's not the case in his case. He hasn't done a bad job throughout the year. He's made one or two which look like mistakes, but probably if you closely analyse them they probably wouldn't have been mistakes anyway."

Mercedes have lodged an intention to appeal against the stewards' decision to reject their protests over Max Verstappen's dramatic title-clinching Abu Dhabi Grand Prix victory.

Verstappen claimed his maiden Formula One world title in the most dramatic fashion at the Yas Marina Circuit on Sunday after overtaking Lewis Hamilton on the final lap of a decisive last race of the season.

Hamilton was on the brink of being crowned champion for a record eighth time when he built a healthy lead until the safety car was deployed with four laps to go after Nicholas Latifi crashed.

Verstappen pitted to have fresh tyres fitted and had his last chance to win the race – and the championship – when race director Michael Masi ruled lapped cars in between the top two could overtake the safety car, which headed in and allowed one final lap of racing.

The Dutchman passed a stunned Hamilton, with Masi explaining to furious Mercedes team boss Toto Wolff: "We went car racing."

Mercedes launched a formal protest "against the classification established at the end of the competition" as Red Bull basked in the glory of their sensational triumph.

The Silver Arrows complained that Verstappen may have briefly edged in front of Hamilton, who had position as the lead car, behind the safety car and also protested over how rules were applied concerning when lapped cars can overtake under safety-car conditions.

While race stewards accepted Verstappen had "for a very short period of time" moved slightly ahead of Hamilton, they were satisfied that he dropped back behind the leader before the safety car period ended.

The second part of the appeal was also rejected by the stewards, but Mercedes will take the matter further.

A team statement said: "We have lodged notice of intention to appeal the decision of the stewards under Article 15 of the Sporting Code and Article 10 of the Judicial and Disciplinary Rule."

The stewards had declared that "once the message 'safety car in this lap' has been displayed, it is mandatory to withdraw the safety car at the end of that lap" and "notwithstanding Mercedes' request that the stewards remediate the matter by amending the classification to reflect the positions at the end of the penultimate lap, this is a step that the stewards believe is effectively shortening the race retrospectively, and hence not appropriate".

"Accordingly, the protest is dismissed," the stewards added.

Max Verstappen and Red Bull were celebrating after rivals Mercedes failed to overturn the result of an extraordinary final race of the Formula One season in Abu Dhabi.

Verstappen won the race and with it the championship on Sunday, passing title rival Lewis Hamilton on the last lap after a safety car deployment transformed the race.

Starting the race all square with Verstappen at the top of the standings, it seemed as though Hamilton would clinch a record eighth driver's title when he built up a healthy lead in the closing stages.

However, the British driver's advantage was wiped out when the safety car came out after Nicholas Latifi crashed with four laps remaining.

Verstappen pitted to get fresh tyres for a potential shot at passing the Mercedes man, and he got that chance when race director Michael Masi ruled lapped cars could overtake the safety car, which headed in and allowed one lap of racing between the contenders.

Verstappen beat Hamilton as Mercedes fumed, with Masi explaining to Mercedes team boss Toto Wolff: "We went car racing."

As Red Bull soaked up their sensational victory, Mercedes launched a formal protest "against the classification established at the end of the competition".

They complained that Verstappen may have briefly edged in front of Hamilton, who had position as the lead car, and also protested over how rules were applied concerning when lapped cars can overtake under safety-car conditions.

While race stewards accepted Verstappen had "for a very short period of time" moved slightly ahead of Hamilton, they were satisfied that he dropped back behind the leader before the safety car period ended.

The second part of the appeal was also rejected by the stewards, who announced that news in a statement.

The stewards declared that "once the message 'safety car in this lap' has been displayed, it is mandatory to withdraw the safety car at the end of that lap" and "notwithstanding Mercedes' request that the stewards remediate the matter by amending the classification to reflect the positions at the end of the penultimate lap, this is a step that the stewards believe is effectively shortening the race retrospectively, and hence not appropriate".

"Accordingly, the protest is dismissed," the stewards added.

It remained to be seen whether further steps would be taken by Mercedes.

Red Bull team principal Christian Horner, quoted by the BBC, said: "We are going to go and celebrate this championship now. Thank you very much."

Mercedes have had their first protest against the result of the Abu Dhabi Grand Prix dismissed by race stewards.

Max Verstappen won the race and the championship in dramatic circumstances on Sunday, passing Lewis Hamilton on the final lap after the safety car had been deployed.

Having entered the race all square with Verstappen at the top of the standings, it seemed as though Hamilton would clinch a record eighth driver's title when he built up a healthy lead in the closing stages.

However, Hamilton's advantage was wiped out by the deployment of a safety car that was sent onto the track after Nicholas Latifi crashed with four laps remaining.

Verstappen pitted to get fresh tyres for a potential shot at passing the Mercedes man, and he got that chance when race director Michael Masi belatedly ruled lapped cars could overtake the safety car, which headed in and allowed one lap of racing between the contenders.

Verstappen beat Hamilton as Mercedes fumed, with Masi explaining to Mercedes team boss Toto Wolff: "We went car racing."

As Red Bull celebrated their sensational victory, Mercedes protested "against the classification established at the end of the competition".

Mercedes' protest alleged Verstappen had overtaken Hamilton before the safety car pitted and opposed the decision to allow the selection of lapped cars to pass.

While race stewards accepted Verstappen had "for a very short period of time" moved slightly ahead of Hamilton, they were satisfied that he dropped back behind the leader before the safety car period ended.

Red Bull had argued that Hamilton had never been overtaken, rather that both cars were "on and off the throttle" and that there were "a million precedents" where cars had moved alongside an opponent while under a safety car before dropping back.

No decision had yet been announced by the FIA – the sport's governing body – with regards to Mercedes' second protest.

Mercedes launched an official protest after Max Verstappen controversially beat Lewis Hamilton to the Formula One title on the final lap of the season.

Hamilton had reeled in Verstappen in the closing weeks of the campaign and led his rival for much of Sunday's Abu Dhabi Grand Prix.

Having entered the race all square at the top of the standings, the victor of a battle between Hamilton and Verstappen would decide the championship.

Hamilton's advantage was wiped out by a safety car, under which Verstappen pitted to get fresh tyres for a potential shot at passing the Mercedes man.

He got that chance when race director Michael Masi belatedly ruled lapped cars could overtake the safety car, which headed in and allowed one lap of racing between the contenders.

Verstappen beat Hamilton as Mercedes fumed, with Masi explaining to Mercedes team boss Toto Wolff: "We went car racing."

As Red Bull celebrated their sensational victory, Mercedes protested "against the classification established at the end of the competition".

The protest focuses on articles 48.8 and 48.12 in the sporting regulations of governing body the FIA, each of which relate to the safety car.

Article 48.8 instructs that cars cannot overtake behind a safety car, with footage suggesting Verstappen may have briefly edged in front of Hamilton, who had position as the lead car.

Article 48.12 relates to when lapped cars can overtake under the safety car.

Mercedes boss Toto Wolff believes this year's dramatic Formula One title race is "amazing for the sport".

Lewis Hamilton and Max Verstappen head into the final grand prix of the season level on points at the top of the drivers' championship.

Mercedes, meanwhile, are bidding to win their eighth constructors' title. The gap between themselves and Red Bull is 28 points, though Wolff's team could still lose the crown to their rivals.

With such drama promised in Abu Dhabi this weekend, Wolff thinks it can only serve as a boost to F1, which had become predictable due to Mercedes' dominance. 

Indeed, Hamilton is aiming for a record eighth world title and a fifth consecutive championship triumph.

Since 2014, Hamilton has only failed to win the championship on one occasion, finishing second to team-mate Nico Rosberg in 2016, while Verstappen and Red Bull are bidding for a maiden title.

"The final race will be intense, but it's important to not get distracted, to just keep our heads down, our feet on the ground and bring the performance that we had last time out," Wolff said in a release on Mercedes' official team website.

"We're grateful to still be in this fight. The fact that both championships will be decided at the season finale proves just how hard both sides have been challenging each other and pushing each other forward.

"It's all or nothing for the season finale and that's amazing for the sport, amazing for the fans and amazing for all of us, too.

"We're also relishing the challenges of racing in Abu Dhabi this weekend, at a circuit that has gone through quite a few changes since we last raced there.

"There are new sections of track to understand and that really is a step into the unknown for everyone. So, it's going to be another exciting weekend!"

Verstappen won the 2020 Abu Dhabi Grand Prix, and in the unlikely event both he and Hamilton finish outside of the points, it will be the Dutchman who wins the title courtesy of his nine race victories for the season.

Mercedes had won the previous six races in Abu Dhabi prior to Verstappen's victory last year. The Red Bull star is aiming to become the first F1 champion from the Netherlands, and he would be the fourth-youngest champion at the age of 24 years, two months and 12 days.

Emerson Fittipaldi and Clay Regazzoni, in 1974, are the only other F1 title rivals to have gone into the last race of a season level on points. Never in the history of the championship has a season ended with two drivers tied at the top of the standings.

Formula One "woke up the lion" in Lewis Hamilton when he was disqualified from qualifying due to a DRS issue in Brazil, Toto Wolff says.

Hamilton, who was already serving a penalty for taking a new engine at last week's Sao Paulo Grand Prix, was forced to start from the back of the grid in the sprint race but recovered to take fifth.

In the main race, the Mercedes man then triumphed from 10th despite an incident that saw title rival Max Verstappen force him wide and avoid punishment.

The FIA dismissed an appeal for that incident to be reviewed again this week, while a stewards' inquiry in Brazil saw Verstappen only fined after he touched Hamilton's car.

These factors may have frustrated Hamilton, but he has not become distracted, instead adding another victory at the Qatar Grand Prix on Sunday to close to within eight points of Red Bull's Verstappen.

"Lewis is totally in the zone," Mercedes team principal Wolff told Sky Sports. "They woke up the lion in Interlagos on that Saturday and you see that."

Hamilton added: "The last two weeks have been fantastic, just amazing. But there's no time for celebration.

"I'll be back with the team already again next week and training tomorrow, stay on it, heads down.

"I don't have too much emotion other than being driven right now, but it's just amazing to be able to close so many points in the last two races which has been important.

"[Red Bull are] obviously still very fast, as you could see today with their fastest lap and both their cars getting past pretty much everyone quite easily. So we've still got our work cut out.

"I'm loving it. I love the close battle, the pressure, the demands it puts on you and the whole team.

"So I thoroughly enjoyed it, but these next two races need even better performance, so we'll be bringing our 'triple A' game for those ones."

Max Verstappen fumed at "stupid idiot" Lewis Hamilton and aimed a middle-finger salute at his title rival in a heated United States Grand Prix session.

The fight for the Formula One title intensified when the pair came close to making contact during FP2 at the Circuit of The Americas on Friday.

Championship leader Verstappen snapped over the team radio after going wheel-to-wheel with Hamilton, saying: "Ha! Stupid idiot!" and making his feelings clear with a gesture to the Mercedes driver.

A Red Bull engineer told Verstappen to "ignore it" as the Dutchman endured a frustrating day, having been caught in traffic at the start of the mid-session short runs.

He could only finish down in eighth in the second session as Sergio Perez set the pace, with Hamilton third behind Lando Norris.

Valtteri Bottas topped the timesheets in the first session, but will take a five-place grid penalty in Austin after having a sixth engine of the season – with three being the limit – fitted and a sixth exhaust.

Silver Arrows team principal Toto Wolff says there is a risk that Hamilton, who trails Verstappen by only six points, could take another grid penalty this season

He added: "I can't say whether we will be taking one and what the percentage is, but obviously the risk is still there.

"What is difficult to evaluate is do you want to pre-empt the situation and take another penalty and take the hit or do you want to really run it and possibly risk a DNF, and that is a discussion that is happening as we speak, and we haven’t come to the right answers yet."

Williams driver George Russell, Bottas' replacement at Mercedes for 2022, and Aston Martin's Sebastian Vettel will start on the back row after they had multiple new engine parts fitted.

Valtteri Bottas, George Russell and Sebastian Vettel have taken grid penalties for the United States Grand Prix this weekend.

Bottas won in Turkey last time out, but a repeat would appear unlikely at the Circuit of The Americas on Sunday after the Mercedes driver had a sixth engine of the season – with three being the limit – fitted and a sixth exhaust.

The Finn, who sits third in the driver standings and was fastest in the first practice session on Friday, will take a five-place penalty for the race in Austin.

Silver Arrows team principal Toto Wolff said: "I think you see that we are suffering with reliability this year, we're going onto the sixth engine for Valtteri, and it is not something we choose to do, but on the contrary; we are trying to really get on top of the problems, and we haven't understood fully [what they are]."

Wolff says there is a risk that Lewis Hamilton could take another grid penalty this season as he battles for the title with Max Verstappen.

He added: "I can't say whether we will be taking one and what the percentage is, but obviously the risk is still there.

"What is difficult to evaluate is do you want to pre-empt the situation and take another penalty and take the hit or do you want to really run it and possibly risk a DNF, and that is a discussion that is happening as we speak, and we haven’t come to the right answers yet."

Williams driver Russell, Bottas' replacement at Mercedes for 2022, and Aston Martin's Vettel will start on the back row after they had multiple new engine parts fitted.

Hamilton was 0.045 seconds slower than his team-mate Bottas in FP1, with his championship rival Verstappen third-quickest – almost a second slower than Bottas.

Lewis Hamilton cut a frustrated figure over Mercedes' decision to pull him in for a pit stop late in the Turkish Grand Prix.

Hamilton seemed determined to finish the race in the rain in Istanbul on the same set of tyres, turning down several calls for him to pit.

Finally, on the 51st lap out of 58, Hamilton – who at the time was in third place having started 11th on the grid due to the 10-place penalty he took into the weekend for changing engine – heeded his team's call to come in to switch onto intermediate tyres.

Yet as the seven-time world champion came back out, he had fallen to fifth place, much to his annoyance.

"Why did you give up that place?" Hamilton questioned over the radio, as he was forced to hold off Pierre Gasly to finish fifth, behind Charles Leclerc, Red Bull duo Sergio Perez and Max Verstappen and Mercedes team-mate Valtteri Bottas, who cruised to his first race victory of 2021.

Esteban Ocon finished within the top 10 having not changed tyres at all, and Hamilton was in a prickly mood when interviewed by Sky Sports.

Asked if he was aware he would drop down two places when he went into the pits, Hamilton said: "I didn't know at that time, I could probably have assumed that I would.

"The guys were only 15 seconds behind, it's a 24-second pit stop so I knew that I'd lose perhaps one."

Of the initial tyres potentially lasting the whole race, Hamilton added: "Ocon's did I heard so I assume they probably could.

"The tyres are bald so you don't know how far they're going to go so there's definitely the worry of the life of the tyre but also I wasn't really that fast at the end there.

"I was struggling, had little grip, not really sure why. Then all of a sudden I'd have not such a bad pace but I was losing performance to the guys behind."

Hamilton acknowledged he may have made an error not coming in for a pit earlier in the race, when Mercedes initially advised, but he believes the wrong call was made to switch so late.

"In hindsight I should have either stayed out or come in much earlier," he said. "When you come in with eight laps to go you don't have time to go through the draining phase of that medium tyre on a drying track.

"So I went through this whole sliding change where I nearly lost more positions. A bit frustrated but it is what it is. 

"It felt good to be in third and I thought if I could just hold onto this it's a great result from 11th. Fifth is worse, but it could be worse."

There was an eight-point swing in the championship title race, with Verstappen now six ahead of Hamilton heading into the United States Grand Prix in two weeks' time.

Mercedes boss Toto Wolff, however, insisted the correct call was made.

"[Pitting earlier] would have been better than what we ended up with. But it was measured and in the car, he didn't see how much he was dropping off. It was clear that had he stayed out then he would have lost out to Gasly," he told Sky Sports.

"The correct call would probably have been taking it very conservative and pitting when everybody else pitted for the inters, coming out behind Perez and Leclerc and fighting with them for P3. That was probably correct, but that is only with hindsight."

Lewis Hamilton could start the Turkish Grand Prix at the back of the grid on Sunday as Mercedes are considering taking an engine penalty for the Formula One championship leader.

Seven-time F1 world champion Hamilton leads Max Verstappen by two points in the battle for the title after winning a dramatic Russian Grand Prix to secure his 100th race victory last month.

Verstappen worked his way through the field from the back to finish second after the Red Bull driver had a new power unit fitted in Sochi

Hamilton may face the same challenge at Istanbul Park as his team mull over whether to fit his car with a fourth engine of the season, which would take him over the permitted allowance.

Asked if the Silver Arrows could take the penalty this weekend, team principal Toto Wolff told Sky Sports News: "It's a possibility."

Although the German added: "When, and how, is not yet decided."

Wolff says it is vital Mercedes avoid putting Hamilton in a position where he is danger of not finishing a race.

"Most important is that you don't DNF because of a reliability issue," said Wolff.

"You can cope with swings, whether you finish second, third, I think that is okay, the championship is going to go long. But if you don't finish...

"So we are looking at the parameters of the engines, making sure we don't suffer from any reliability problems."

Hamilton's team-mate Valtteri Bottas started in 17th in Sochi after taking an engine penalty.

Mercedes boss Toto Wolff described Lewis Hamilton's crash with Max Verstappen at the Italian Grand Prix as a "tactical foul" by the Red Bull driver.

The drivers' championship front-runners collided at Monza, having also come together at the British Grand Prix, forcing both to retire from the race.

After labouring behind eventual winner Daniel Ricciardo, who led a McLaren one-two, Verstappen's hopes of victory were seemingly dashed with a pit stop that saw him stationary for 11.1 seconds.

Hamilton then emerged from his pit stop at the start of lap 26 alongside Verstappen, who attempted to sneak down the inside at turn two, only to catch the kerbs and send his car airborne before it landed on top of the Mercedes, with both ending up in the gravel trap.

Having come second in the sprint race, Verstappen extended his championship lead by two points. He now holds a five-point advantage.

The incident is the subject of a stewards' investigation, but Wolff indicated he believes the blame lies with the Dutchman.

"The stewards are going to decide who is to blame. There is predominantly to blame, I guess, we've seen that in the past. I think in football you'd say it was a tactical foul," Wolff told Sky Sports. 

"He probably knew that if Lewis stays ahead, that is the race win possibly.

"I think when you look at turn four, Lewis backed out and that was quite a thing because probably you know he's staying ahead of you. And then incidents where they actually crash, it was clear for Max in there that they would crash.

"I think if we don't manage that in the right way, this is going to continue. They had a high-speed crash at Silverstone, we had one car ending on top of the other one on Lewis' head here, so how far can you go? Maybe next time we'll have a high-speed crash and land on each other."

Hamilton added: "I was racing as hard as I could, finally got past Lando [Norris], I was in the lead so they pitted me, pit-stop was obviously slow, lost a couple of seconds.

"I came out, saw that Daniel came past, Max was coming, I made sure I let a car's width on the outside to him. I went into Turn 1 and I was ahead, I was ahead going into turn two, then all of a sudden he was on top of me."

Asked if Verstappen could have backed out of the corner, Hamilton replied: "Absolutely. Exactly the same scenario that happened in turn four, where I went around the outside, I was in exactly the same position, but I gave way. And that's racing.

"He just didn't want to give way today, he knew when he was going into turn two what was going to happen, he knew he was going over the kerb but still did it. We'll speak to the stewards and we'll see."
