A calm and focussed Max Verstappen on Thursday expressed some relief that his Red Bull team have maintained a very healthy lead over all their rivals despite introducing fewer upgrades this season.Speaking at Silverstone on the eve of opening practice at this weekend’s British Grand Prix, the defending double world champion and series leader oozed confidence. “We’ve had a great start to the year and we are understanding our car better and better with each race - what we want and what we need,” the 25-year-old Dutchman said.“But we are not standing still. It is true that, maybe, other teams speak a bit more about updates and bigger upgrades from one race to the next, but we bring stuff as well because it’s necessary to stay ahead.“So it is definitely a good sign, I think that we’ve done less than some of our competitors - that I think is quite clear and we still have a good margin.“Of course, it’s a bit bigger at some tracks than others, but overall we have a strong base package and it is just for us to make sure that we get all the potential out of it every weekend.”McLaren record in sightVerstappen arrives at Silverstone with an 81-point lead in the drivers’ title race as he heads, seemingly inevitably, to a third successive world title, having won the last five races.“I think our car is not so great on street circuits,” he added. “Places with a lot of bumpy tracks, then our car is not so fantastic and that’s why our winning margin was a bit smaller in Monaco. “It wasn’t fantastic either in Montreal, for example, and we know there are still a few street circuits coming up where potentially it will be, again, a little harder for us.”That admission suggested he may be fretting, but his demeanour and record on form this year suggests there is little his rivals can do other than hope for Red Bull to suffer a reliability problem. Verstappen missed out on victories at Silverstone last year and in 2021 due to debris on the track and a crash respectively and is highly motivated to win at the circuit closest to the team’s headquarters in Milton Keynes.“Yeah, sometimes you get a bit of bad luck?” he conceded. “But we know our car is better probably and more competitive than last year. So I’m just looking forward to the weekend and hopefully a good result.” Having won the last 10 races, Red Bull could draw level with McLaren on a record 11 wins - set by the British team in 1988 - if they triumph at Silverstone on Sunday.Hamilton positive on new contractLewis Hamilton confirmed oyesterday that talks about a new contract with Mercedes had proceeded beyond salary and duration and were now focused on fine details.Speaking at Silverstone ahead of his home British Grand Prix, a race he has won a record eight times, the seven-time world champion reiterated his confidence in the ‘Silver Arrows’ and his belief that they can catch and overhaul Red Bull. He also felt thrilled to see filming begin of the Hollywood movie about Formula One during the weekend at the circuit. Asked during a mandatory pre-event news conference if recent positive comments about their talks by Mercedes team chief Toto Wolff were true, Hamilton said: “Yes, that’s correct.”He added that a terse radio exchange between them, when Hamilton grumbled about his car’s lack of performance during last Sunday’s Austrian Grand Prix, was typical of the open and honest nature of their relationship. “The best thing about our partnership is that we can be direct with each other,” he said. “Toto is just an out-and-out racer so he was trying to encourage me and that was his way of doing it.“We always learn from our last races, plus - on my side - I’ve reviewed my comments and where I was at mentally and we’ll make sure I adjust that for the future and I feel supported.”Hamilton added that he had been involved in meetings this week to improve this year’s car and a more competitive one next year. “I’m thinking that before the end of this season, we’ll already be well into the contract,” he said, indicating his confidence in the team for the future.“I still have 100 percent faith in this team. It has taken longer for all of us to get to where we want to be and it’s definitely not easy, but I believe that we will get there.“We’ve just got to continue to work and chip away at it and that’s what we’re trying to do. So that’s why we’ve got the upgrade here for the front wing this weekend.”Hamilton also expressed his enthusiasm about an as yet untitled F1 movie, being produced by Apple Original Films, which begins filming at Silverstone this weekend during the British Grand Prix.“It’s massively exciting to see it all coming together,” said Hamilton. “To know that we’re finally starting to film this weekend! There’s nerves, naturally, because it’s something we’ve been working on for so long.”Images of an additional, fictional 11th team, APXGP, and their car have been offered to fans. “We want everyone to love it and to really feel that we encapsulate what the essence of this sport is all about - that’s our goal and I hope we can do you proud.”Hamilton’s Dawn Apollo Films is involved in the production which includes Hollywood star Brad Pitt playing one of the APXGP drivers.“The fact that we’ll have all the original characters that are actually on the grid and then Brad is pretty cool,” said Hamilton. “Brad is such an iconic actor and he’s always done an incredible job. I can’t tell you how excited I am to have him in the movie.”A garage and pit-wall area have been prepared and dedicated to the APXGP team for the weekend.
