When was Barcelona's first Grand Prix?

A number of circuits in Spain have featured on the calendar over the decades, with the Pedralbes street track (1951 and 1954) and the Montjuïc Circuit near Barcelona (1969, 1971, 1973 and 1975) both hosting events before F1 prioritised racing at alternative venues near Madrid and Seville.

Built as part of the Olympics development programme, it didn't take long for the sport to make its debut at the Circuit de Barcelona-Catalunya. Just two weeks after it hosted its first event – a round of the 1991 Spanish Touring Car Championship – the paddock arrived for an unforgettable inaugural race.

A spectacular drag race between Nigel Mansell and Ayrton Senna saw the Briton come out on top, and the circuit has seen plenty of action since, including a momentous collision between Mercedes team mates Lewis Hamilton and Nico Rosberg in 2016.

In 2023, the layout used by F1 was updated to align with the configuration seen in MotoGP, removing the chicane before the final corner. It was also announced earlier this season that the venue will continue hosting Grands Prix on rotation with the Circuit de Spa-Francorchamps until at least 2032, while the newly-built Madring adopts the Spanish Grand Prix moniker.

What’s the circuit like to drive?

The circuit has been a favourite for pre-season testing over the years due to its long straights and variety of corners, with tyre management adding an extra challenge for the drivers.

It produces a relatively short lap but the combination of long, sweeping turns, quick corners and a twisty section means that there is nowhere for teams to hide, making the Circuit de Barcelona-Catalunya a good indicator for the true pecking order.

"Barcelona is a nice circuit, but everyone knows it like the back of their hand, which kind of makes it feel like home, because it’s the one that we have historically spent a lot of time driving at," explains former Renault F1 driver Jolyon Palmer.

"It’s really flowing and tough on the neck and the body because of the long corners coming through Turns 3 to 4 and Turn 9. It’s also tough on the front-left tyre, with tyre wear generally high in Barcelona thanks to abrasive tarmac.

"Overtaking can be tricky, with Turn 1 pretty much the only spot you can pass at – it’s also the trickiest corner. Turn 4 to 5 is a nasty, downhill braking zone, which again can sucker you into braking a little bit late, but because there’s a bit of camber on it, you can miss the apex slightly and not lose a heap of time.

"The previous final sector was not a pleasure to drive. You had to balance your tyre performance in the first and final sector, it felt really slow, and you squirmed your way around the final chicane trying to compete the lap. But that’s all gone since 2023."

Where are the Straight Mode zones and overtake detection?

As a reminder, and as explained in our pre-season summary of regulation changes, Straight Mode is a different aerodynamic configuration that allows cars to reduce their drag, making them more efficient when accelerating up towards top speed.

The rear wing continues to open up a gap – just like it did when drivers used DRS (the Drag Reduction System) in the past – but now the front wing also moves. The uppermost front wing elements drop down at the same time the rear wing’s top element does.

This is a mode that is used on every single lap in dry conditions, in every area that is designated for it. Essentially, the car will adapt between two different configurations depending on where it is on the track, providing maximum downforce in corners but then less drag on straights.

In Barcelona, there are four Straight Mode zones, commencing with a run along the start/finish straight, then between Turns 3 and 4 and between Turns 5 and 7, before another straight between Turns 9 and 10.

Meanwhile, Overtake Mode replaces DRS and is a new power mode that allows a driver to recharge more electrical energy, and generate an additional electrical power profile, so they can sustain a higher speed for a longer period.

There is one detection point per lap for this mode – expected to be out of the final corner on many occasions, leading onto a long straight – and it will be available to drivers on the following lap as long as they stay within a second of the car in front at that detection point.

In Barcelona, the Overtake Detection line comes at Turn 13, while the Overtake Activation line follows just before Turn 14, leading onto the start/finish straight.
