Lewis Hamilton claimed his 106th career win - and his first triumph with Ferrari - during Sunday's Barcelona-Catalunya Grand Prix.

The seven-time champion now trails championship leader Kimi Antonelli by 41 points after the Italian retired from the event.

Mercedes driver George Russell finished second while McLaren's Lando Norris took third, creating the first all-British podium since the 1968 United States Grand Prix.

BBC F1 correspondent Andrew Benson responds to your questions after the race in Spain.

With Lewis Hamilton back in winning form, is he now a genuine challenger for an eighth title? Might Ferrari shift focus toward supporting him in the championship battle? - Liam

Lewis Hamilton became the first non-Mercedes winner of the season and sits second in the standings, 41 points behind Kimi Antonelli, after his Spanish victory.

Nevertheless, it remains premature to draw firm conclusions about his title prospects.

Prior to the Barcelona success, suggestions of Hamilton or Ferrari as championship contenders appeared unrealistic amid Mercedes' early-season dominance.

A major aerodynamic update for the Ferrari, combined with other elements, enabled Hamilton and his team to deliver the quickest combination on track that day.

Yet several factors converged favorably. Mercedes altered their approach to protect against Hamilton's initial pit stop.

They adjusted from ideal timings in a two-stop scenario to secure position, potentially making Hamilton's three-stop plan quicker from that point.

A virtual safety car period then provided Hamilton with an advantageous stop, allowing him to maintain the lead.

Absent that intervention, he would still have possessed the fastest car but would have needed to overtake Lando Norris' McLaren plus the Mercedes pair - or perhaps just one after Antonelli's late retirement.

Additionally, Ferrari currently trail in power output compared to Mercedes. Barcelona does not demand high power sensitivity, and the Ferrari excels in cornering, particularly the types found there.

The upcoming trio of events in Austria, Britain and Belgium all feature power-sensitive circuits. At present, Ferrari would likely struggle to match Mercedes at those venues.

However, reports indicate a Ferrari power-unit upgrade is imminent following approval for two units this year and next. The extent of its impact remains uncertain.

Overall, Hamilton's Spanish success makes the title discussion plausible, yet further results from additional races are required before confirming his contender status.

Are Charles Leclerc's qualifying difficulties caused by pressure from Lewis Hamilton's improved performances, or does he face genuine braking issues? - Rob

To answer properly, Spain must be distinguished from the prior two races.

Leclerc clearly encountered challenges in Canada and Monaco, especially regarding the Ferrari's braking behavior.

He had tested alternative brake discs to Hamilton's, which failed to suit his preferences.

In Spain, he reportedly adopted Hamilton's brake configuration and felt more comfortable.

Leclerc outperformed Hamilton across practice sessions, delivered impressive race-simulation laps on Friday that drew attention from Mercedes, and was quicker than his teammate in qualifying's second segment.

Leclerc then crashed during his opening Q3 lap.

He identified Turn Four as a weakness throughout the weekend relative to Hamilton. Attempting to brake as late as his teammate succeeded on entry but carried him wide on exit, disrupting his line and causing the car to lose grip before hitting the barrier.

As Hamilton noted: "I was braking very late into Turn Four, which had been visible, and I think Charles probably tried to carry a lot of speed into that corner and unfortunately it didn't work out for him."

During the race, Leclerc charged forward from tenth on the grid with strong early progress. Team principal Frederic Vasseur later revealed a mid-race strategy adjustment, implying a shift from three stops to two.

Whether this explained his reduced pace compared to Hamilton, as observed by rivals, is unclear.

Vasseur commented post-race: "He had a good feeling with the car, he was in confidence, he was able to fight for the pole position yesterday. Then the fact that we changed the strategy in the middle of the race, it was difficult for him. He pitted once again one lap before the safety car. But I think the approach and the feeling is much better for Charles today than it was three weeks ago."

Across the season, Hamilton leads their qualifying head-to-head 6-4, yet Leclerc holds a marginal average advantage of 0.025 seconds.

Mercedes possess two drivers contesting the drivers' championship. While managing their on-track conduct could prove challenging, does having both in contention represent a positive situation? - Robert

When a squad finds its drivers alone in championship contention without external rivals, the scenario creates tension yet qualifies as what most team principals describe as a favorable challenge.

Mercedes appeared positioned this way through the opening six rounds, having permitted Kimi Antonelli and George Russell to compete freely on track.

Following their intense duels in Canada, Russell indicated the pair had informed team principal Toto Wolff they understood the risks and preferred to continue without interference.

Even so, the team intervened in both Canada and Spain. In Barcelona, they cautioned that the intra-team battle was reducing overall speed and complicating efforts to challenge Hamilton.

The drivers eased their contest temporarily before resuming late, once Hamilton had pulled clear, with Antonelli overtaking Russell for second prior to his retirement.

Wolff subsequently stated the team would review future approaches now that Ferrari poses a greater threat, alongside Lando Norris remaining competitive in the McLaren.

Wolff remarked: "There is a third party now getting involved in the championship fight - constructor and driver. And in that respect, we will discuss internally with the two drivers how we want to handle a situation where we risk holding each other up. I think it's not going to be a problem. It's just maybe we need to recalibrate."

Although Aston Martin's vibration concerns appear resolved, the car seems stagnant or regressing. Has the squad abandoned this year's chassis to prioritize next season? If so, how might this influence Fernando Alonso's plans? - Brendan

Aston Martin have not abandoned their 2025 campaign.

Their relative decline stems from introducing almost no performance upgrades so far, unlike competing teams.

They opted to consolidate resources under the cost cap for one substantial update rather than incremental changes across multiple events.

That development is anticipated around the Belgian Grand Prix, three races from now.

An enhanced Honda power unit has also been confirmed. While Honda has not specified timing, team sources indicate it will likely arrive after the summer break near the Dutch Grand Prix.

Aston Martin's issue is that even if the aerodynamic package delivers a two-second lap gain - an exceptional improvement - it would only elevate them to Racing Bulls or Audi levels.

This would represent progress from their current position but remains distant from their ambitions.

The upgrade carries significance across multiple areas, including Fernando Alonso's future.

From the team's perspective, successful delivery is critical because recent years have featured upgrades that appeared promising on paper yet underperformed on track.

With design legend Adrian Newey aboard and their new wind tunnel operational, they anticipate more consistent results from future developments.

Alonso's contract expires at season's end, and he plans to decide his future after the summer.

He appears to be awaiting outcomes from the car and engine upgrades before committing.

At 45 next month, he has expressed reluctance to conclude his career amid such a difficult season. He maintains he continues to perform at a high standard.

Simultaneously, he would avoid remaining for another disappointing year.

Should Aston Martin show limited prospects for improvement, his options for F1 racing next season would be limited, as a top-four seat is improbable.
