F1 faces a fresh challenge this weekend at the first Spanish Grand at the new Madring, a hybrid street circuit built on the Ifema complex near the city’s international airport.
Hamilton said: “It’s a massively challenging circuit. Of all the new tracks that I’ve gone to, this one, maybe Saudi, are the two closest in terms of how difficult it was to get on top of the car and find the right lines and such.”
Mercedes driver George Russell said: “It’s a crazy circuit, I would put it. Arguably one of the most risky circuits of the whole calendar.
“Because you have real high-speed corners, sort of Jeddah-esque, the walls are very close, so there’s no margin for error, but then you have other corners… where you’re coming from a high speed into a slow braking zone, you’re braking and turning at the same time, so locking tyres are going to be easy and if you lock up you’ll be straight in the wall.
“So, excited to try that out, I think it’s going to be really challenging for us as drivers, the race is going to be challenging to overtake, so on the whole it’s not an easy one.”
Russell heads into the race 66 points behind team-mate Kimi Antonelli after the Italian’s landmark victory in Monza from 19th on the grid.
The Briton acknowledged that his title hopes with nine or 10 races left, amid uncertainty about the end of the season, were fading fast.
“I would definitely need some luck and I need some good performances,” Russell said. “It’s not really something I’m thinking about, because he’s performing better than me, so he deserves to be leading the championship.
“There’s still a long way to go, but he’s yet to have a bad weekend in terms of performance.
“So he’s performing exceptionally well, my performances are better, but if I want to win this championship, I’m going to need some luck on the way. But it’s not something I’m focused on. I’m focused on driving faster and just finding more performance.”
Antonelli said: “I don’t really want to try thinking about the championship. I think Monza was the proof that I wasn’t driving thinking about, or worrying about the championship. I was just driving to win, to do my best. So that’s the mindset.”
The Italian said his win in Monza was “so far the best day of my life and definitely one I will remember forever”.
He said a day karting with Mercedes on Monday helped him move on from the excitement of the day before.
“After Monza, that night, that day overall, I was very excited. But then going karting on Monday helped me to go back to earth, just go back to the ground.
“It was a good day, good fun day with the team. It was also a way to remind myself where I came from, all the journey that was done.
“And then about pressure, I try to embrace it as much as possible. And I try to see it as a positive thing and try to see it as an opportunity too. That’s also what is helping me to stay calm under difficult situations.”
