Circuit de Barcelona-Catalunya

The Circuit de Barcelona-Catalunya was built in 1991 and began hosting the Spanish Grand Prix that same year. Construction also coincided with the Olympic Games scheduled to take place in Barcelona{{cite web |url=http://en.espnf1.com/f1/motorsport/circuit/1315.html |title=Circuit de Catalunya |date=November 2009 |access-date=13 August 2010 |last=Furnell |first=Claire |work=en.espnf1.com |publisher=ESPN EMEA Ltd. }} the next year, where the circuit acted as the start and finish line for the road team time trial cycling event.[https://web.archive.org/web/20080528011647/http://www.la84foundation.org/6oic/OfficialReports/1992/1992s2.pdf 1992 Summer Olympics official report.] Volume 2. pp. 305–7. The Circuit de Barcelona-Catalunya should not be confused with the Montjuïc circuit, which hosted the Spanish Grand Prix four times between 1969 and 1975 and, unlike the Circuit de Barcelona-Catalunya, is actually located within the city of Barcelona.

Because so much testing is done at this circuit, Formula One drivers and mechanics are extremely familiar with it. This has led to criticism that drivers and mechanics are too familiar with Catalunya, reducing the amount of on-track action.

When first used, overtaking was frequent as cars could follow closely through the last two corners and slipstream down the long straight. As aerodynamic balance became more critical, this overtaking method drastically decreased as the cars were unable to follow each other through the fast final corner due to turbulence created by the leading car. The 2007 season saw the first of the two final sweepers replaced with a slow chicane to reduce speeds through the final corner, where serious accidents could occur, and in an effort to improve overtaking.{{cite web|title=How Hermann Tilke conquered the F1 calendar|date=5 February 2009 |url=http://www.f1fanatic.co.uk/2009/02/05/how-hermann-tilke-conquered-the-f1-calendar-1996-2009-video/|access-date=23 December 2012|publisher=F1 Fanatic}}{{Cite news|url= https://www.motorsportmagazine.com/articles/single-seaters/f1/how-the-circuit-de-barcelona-catalunya-brought-f1-to-life-in-spain |title= How the Circuit de Barcelona-Catalunya brought F1 to life in Spain |last= Smith |first= Damian |work= Motor Sport magazine |access-date= 12 May 2021 |date= 11 August 2020}} However, it has been criticised for failing to achieve the latter aim and for causing congestion during qualifying sessions.{{Cite news|url= https://www.autosport.com/f1/news/the-changes-barcelona-needs-to-provide-a-modern-day-f1-spectacle/6505904/ |title= The changes Barcelona needs to provide a modern-day F1 spectacle |work= Autosport |last= Boxall-Legge |first= Jake |date= 10 May 2021 |access-date= 10 May 2021}} The 2022 race was, until now, the last Formula One race to use the chicane, with the original configuration restored ahead of the 2023 race.{{cite news|url=https://www.formula1.com/en/latest/article.circuit-de-barcelona-catalunya-to-feature-new-configuration-for-2023-spanish.6ZQgemg7eOlAJbBtu56PHE.html|title=Circuit de Barcelona-Catalunya to feature new configuration for 2023 Spanish Grand Prix|date=27 February 2023|work=f1.com|access-date=27 February 2023}}

The Circuit de Barcelona-Catalunya has hosted a motorcycle Grand Prix since 1992, originally the European motorcycle Grand Prix from 1992 and later the Catalan motorcycle Grand Prix since 1996, and hosted two rounds in 2024, with the season-ending one-off Barcelona motorcycle Grand Prix replacing Valencia because of flooding in the Valencia area. There are at least five points on the track (turns 1–2, 4, 5, 10, 14) where riders are known to overtake. As in Formula 1, Turn 1 is arguably the most popular place for overtaking. The circuit is not known to produce copious amounts of overtaking, despite the long straights. Originally, the Formula 1 circuit changes were not instituted for MotoGP; however, after a fatal crash in the 2016 MotoGP round involving a Moto2 rider, Luis Salom, the Formula 1 layout was implemented to slow down riders for safety purposes. The FIM made a further change to the chicane for 2017 by moving up the chicane to prevent riders from cutting the pit lane entrance, but that was abandoned because the motorcycle chicane had a surface change that created more safety issues with the transition. Further changes were made to the circuit in December 2017 as grandstands were removed to add additional runoff that allowed the FIM to eliminate that chicane (although the Turn 10 hairpin was kept).

The track was resurfaced in 2018 as a result of calls by MotoGP riders to improve the amount of grip on the surface. Previously the track had been resurfaced in 2004.

The circuit hosted many other international racing series, including the FIA Sportscar Championship (1999–2002), European Touring Car Championship (2003), FIA GT Championship (2003), Deutsche Tourenwagen Masters (2006–2009), European Le Mans Series (2008–2009, 2019, 2021–present), and World Series Formula V8 3.5 (2002–2004, 2006–2013, 2016), GT World Challenge Europe Endurance Cup (2017–present), 24h de Barcelona Trofeu Fermí Vélez, and FIA World Rallycross Championship (2015–present).

Since 2016, the racetrack hosts the 24h BiCircuit Festival, an ultra-distance cycling event featuring 24-hour, 12-hour and 6-hour races for soloists and relay teams up to 8 riders.[https://www.circuitcat.com/es/eventos/bicircuit-festival/ BiCircuit Festival at the Circuit de Barcelona-Catalunya official website][http://24hmadformbicircuit.es/ 24h BiCircuit Festival official website]

For the 2020 Formula One season Liberty Media expected the calendar would consist of twenty-one Grands Prix and that any new races would come at the expense of existing events, in particular the Dutch Grand Prix in Zandvoort replacing the Spanish Grand Prix on Circuit de Barcelona,{{cite news|url=https://www.racefans.net/2019/05/09/sainz-fears-its-too-late-to-save-spanish-gp-for-2020/|title=Sainz fears it's "too late" to save Spanish GP for 2020|first=Keith|last=Collantine|publisher=Racefans.net|date=9 May 2019|access-date=29 February 2020}} but later negotiated an agreement with the teams to allow up to twenty-two Grands Prix, salvaging the Spanish Grand Prix. Before 2021 season, the circuit's F1 deal was extended for one more year. However, in November 2021, the circuit's F1 deal was extended to 2026,{{cite news|url=https://www.formula1.com/en/latest/article.breaking-formula-1-renews-deal-with-the-circuit-de-barcelona-catalunya-until.2kv0OwJ2uSikb4lhVC9Nh9.html|title=Formula 1 renews deal with the Circuit de Barcelona-Catalunya until 2026|date=26 November 2021|work=f1.com|access-date=24 September 2022}} with 2025 as the last year the Spanish Grand Prix will be held here; a new circuit in Madrid built around the {{ill|Recinto Ferial de IFEMA|lt=IFEMA exhibition centre|es}} in {{ill|Campo de las Naciones|es}} would be its home from 2026 onwards.{{cite news |last1=Benson |first1=Andrew |title=Spanish Grand Prix to move from Barcelona to Madrid in 2026 |date=23 January 2024 |url=https://www.bbc.co.uk/sport/formula1/68065785 |publisher=BBC Sport |access-date=23 January 2024}}

Barcelona has the 3-star FIA Environmental Accreditation and the ISO 14001 certification. In a 2021 report, it was ranked the second most sustainable racetrack in the world, together with Circuit Paul Ricard and behind Mugello Circuit.[https://racer.com/wp-content/uploads/sites/85/2021/07/Racing_towards_a_sustainable_future_2021Edition.pdf Racing towards a sustainable future - A Review of the sustainability performance of international racing circuits] - Enovation Consulting Ltd and Right Hub Srl, June 2021

The circuit has been the site of some memorable moments. In 1991, Ayrton Senna and Nigel Mansell went down the entire front straight side by side while dueling for second place, with Mansell eventually taking the position and ultimately the race itself. In 1994, Michael Schumacher managed to finish in second place despite driving over half the race with only fifth gear. In 1996, Schumacher took his first win as a Ferrari driver, after a dominant performance during a torrential rainstorm. In 2001, Mika Häkkinen suffered a clutch failure while leading the race on the last lap, handing the win to Schumacher. At the 2006 event, Fernando Alonso became the first Spanish Formula One driver to win at his home country's track. In 2016, a crash at turn four took Mercedes drivers Lewis Hamilton and Nico Rosberg out, allowing Red Bull's Max Verstappen to win the race on his first race for the team. Doing so, Verstappen was the youngest to win a race, the youngest driver to stand on the podium, and the youngest to lead a lap of a race, in addition to being the first Dutchman to win a Formula One race.

In 2008, Heikki Kovalainen left the track at {{cvt|240|km/h|mph|abbr=on}} after a wheel rim failure at turn 9. He managed to decelerate to {{cvt|130|km/h|mph|abbr=on}} when he hit the tyre barrier. He was temporarily unconscious and suffered a minor concussion,{{cite web |url=https://www.telegraph.co.uk/sport/2298747/Heikki-Kovalainen-I-dont-remember-accident.html |archive-url=https://ghostarchive.org/archive/20220112/https://www.telegraph.co.uk/sport/2298747/Heikki-Kovalainen-I-dont-remember-accident.html |archive-date=12 January 2022 |url-access=subscription |url-status=live |title=Heikki Kovalainen: I don't remember accident |access-date=13 August 2010 |author1=Andrew Baker |author2=Charlie Caroe |date=28 April 2008 |work=telegraph.co.uk |publisher=Telegraph Media Group Limited }}{{cbignore}} but a few minutes later, spectators were relieved when he gave a thumbs up.

The circuit has been the scene of two debut wins in Formula One. Pastor Maldonado took his first and only Grand Prix victory and podium here in 2012, and in 2016 Max Verstappen won his first Grand Prix. As a result, he became the youngest driver to ever win an F1 Grand Prix race.

At the 2009 motorcycle Grand Prix, teammates Valentino Rossi and Jorge Lorenzo fought all race long for first place, culminating in an overtake on the final corner by Rossi. Riders and pundits described the race as "historic" and "genius".{{cite web |url=https://vimeo.com/32756097 |title=Catalunya 2009 Motogp 'Rossi teaches Lorenzo a lesson!' }}

On 3 June 2016, during Moto2 Free Practice for the 2016 Catalan motorcycle Grand Prix, Luis Salom crashed in turn 12, resulting in the session being red-flagged. After being transferred to the local Hospital General de Catalunya, Salom died of the injuries sustained in the crash. Upon hearing this, FIM decided to change the current layout of the track to the same layout as the one used in Formula One. After off-season discussions, the FIM announced that the track layout would be slightly modified in that the chicane would be moved up a few metres.

The track is demanding of a car's aerodynamic qualities.{{cite news|url=https://www.bbc.com/sport/formula1/44095900|title=Spanish Grand Prix: All you need to know after Lewis Hamilton takes pole|date=12 May 2018|work=BBC Sport|access-date=13 May 2018}} The wind direction at the circuit can change drastically during the day, a significant factor given the importance{{cite web|url=https://www.formula1.com/content/fom-website/en/championship/inside-f1/understanding-f1-racing/Aerodynamics.html|title=Aerodynamics|quote=Ask any engineer in the pit lane and they'll tell you that the most important consideration in F1 car design [...] is aerodynamics.|publisher=Formula One World Championship Limited|access-date=27 June 2016}}{{cite web|url=http://www.f1technical.net/articles/10|title=Aerodynamics in racing|quote=Nowadays, aerodynamics is the utmost important factor in Formula One car performance.|date=14 May 2009|publisher=f1technical.net|access-date=27 June 2016}} of aerodynamics to modern Formula One cars. It is then difficult to find a good setup since cars can have massive aerodynamic drag and understeer on one part of the circuit in the morning, but suffer oversteer at the same part of the circuit in the afternoon. A given tyre compound can work well when tested, but not so well a couple of months later. These changeable conditions can make for unexpected performances from some teams during the race. The changeable wind conditions have also caused accidents at the circuit, with Fernando Alonso's testing accident in 2015 partly blamed on the severity of the wind.

Through 2015, the MotoGP layout used the 1995–2003 version of the Grand Prix circuit. This was originally the same layout as Formula One, but in 2004 a new, slower La Caixa turn was built; the motorcycles continued to use the old version, and they also ignored the shorter Europcar turn and RACC chicane. The F1 layout was implemented for MotoGP originally in 2016 following the fatal accident of Luis Salom in Europcar corner on 3 June 2016. Race control switched to the F1 circuit for qualifying and the race on 5 June 2016. On 15 December 2016, the FIM announced the change was permanent by announcing plans for a chicane ahead of the current car chicane. However, during the 2017 race, the new chicane was deemed dangerous by riders because of a surface change, and the car chicane was used during that event. After changes to the track in the off-season including removing grandstands in Turn 12, creating additional runoff and a complete repaving of the circuit, the F1 layout from 2004 to 2006, including the new La Caixa hairpin instead of the long sweeper, was used, eliminating the chicane.

For 2021, the La Caixa hairpin was remodelled again, slower than the original one but faster than the F1 one. The alterations were done to improve safety for the drivers.{{Cite web|last=|first=|date=1 February 2021|title=Circuit de Barcelona-Catalunya complete remodelling of Turn 10|url=https://www.formula1.com/en/latest/article.circuit-de-barcelona-catalunya-complete-remodelling-of-turn-10.giY8HxbKVmtub2ZjyvI1B.html|url-status=live|archive-url=https://web.archive.org/web/20210201172432/https://www.formula1.com/en/latest/article.circuit-de-barcelona-catalunya-complete-remodelling-of-turn-10.giY8HxbKVmtub2ZjyvI1B.html |archive-date=1 February 2021 |access-date=1 February 2021|website=formula1.com|language=en}}

The World RX of Catalunya used parts of the track near turns 11–15, with two additional gravel sections.

From the 2023 Spanish Grand Prix, Formula One will use the layout used by MotoGP since 2021 removing the chicane in the last sector of the lap that Formula One had used every year since it was introduced in 2007 reverting the final corners for Formula One cars to a sweeping fast configuration that Formula One last used in 2006.{{cite web |last1=Cooper |first1=Adam |title=Spanish GP drops final sector chicane for 2023 F1 race |url=https://www.motorsport.com/f1/news/spanish-gp-drops-final-sector-chicane-for-2023-f1-race/10437098/ |website=www.motorsport.com |publisher=Motorsport Network |access-date=26 February 2023}}

A {{convert|1,047|m|yd|abbr=on}} long pit straight leads them into turn 1 which is the main overtaking point at Catalunya, as it is a braking zone at the end of a long DRS straight. The inside and outside are equally difficult for overtaking; drivers who can hold the line around the outside of turn one, can get the inside line for turn two. The corners themselves make up a medium-speed chicane – drivers brake rather late for turn one (Elf){{cite web|title=Catalunya track guide|url=http://www.f1fanatic.co.uk/wp-content/uploads/2012/03/catalunya_barcelona_2012.jpg|publisher=F1 Fanatic|access-date=23 December 2012|archive-url=https://web.archive.org/web/20150924050726/http://www.f1fanatic.co.uk/wp-content/uploads/2012/03/catalunya_barcelona_2012.jpg|archive-date=24 September 2015|url-status=dead}} and shift down to gear two, and turn two is almost full throttle as they try to gain as much exit speed as possible. Turn 3 (Renault) is a long, flat-out (in most cars) right-hander that has a g-force of about four, and it leads to a short straight before turn 4, the Repsol curve. Another right-hander, turn four is similar to Monza's Curva Parabolica – drivers brake and take an early apex (in third gear), carrying great speed out of the exit. Turn 5 (Seat) comes immediately after and is a slow left-hander taken in second gear which drops rapidly downhill towards the left kink of turn 6 which is ignored by F1 cars. Turns 7 and 8 make up a medium-speed, uphill, left-right chicane. Drivers brake and shift down to gear three, and must not run too wide as turn eight has a large kerb on its apex which could potentially damage cars' suspensions. Turn 9, Campsa Corner, is a very fast, sixth-gear right-hander which is made incredibly difficult by being completely blind (drivers cannot see the apex on approach). It is initially quite steep uphill but the exit is then downhill, so it is quite easy to run wide onto the astroturf. The long back straight leads into turn 10 (La Caixa), a third-gear, left-hand corner, then turns 11 and 12, a left kink before a long, slow, third-gear right. Turn 13 and 14, a very fast, sixth-gear double right-hander which takes cars across the start/finish line.

As of June 2025, the fastest official race lap records at the Circuit de Barcelona-Catalunya are listed as:

The public attendance at the Spanish Grand Prix, and at the Catalan motorcycle Grand Prix, have fallen significantly since 2007, which has complicated the economic solvency of this circuit.{{cite web|url=https://www.thebestf1.es/analisis-la-asistencia-al-gp-de-espana-desde-su-llegada-a-montmelo-en-1991/|title=ANÁLISIS: La asistencia al GP de España desde su llegada a Montmeló en 1991|website=THEBESTF1.Es|date=February 2018|access-date=14 January 2020}}{{cite web|url=https://www.europapress.es/deportes/formula1-00312/noticia-asistencia-circuit-montmelo-sigue-bajando-87511-espectadores-carrera-20190512185146.html|title=La asistencia al Circuit de Montmeló sigue bajando con 87.511 espectadores en carrera|website=europapress/deportes/fórmula 1|access-date=14 January 2019}}{{cite web|url=https://www.lavanguardia.com/vangdata/20150611/54432201754/evolucion-asistentes-moto-gp-catalunya-montmelo.html|title=Evolución de los asistentes al GP de Catalunya de Moto GP en Montmeló|website=LA VANGUARDIA|date=10 June 2015|access-date=14 January 2020}}{{cite web|url=https://www.autobild.es/noticias/baja-asistencia-gp-catalunya-cuales-son-motivos-265235|title=Baja asistencia al GP de Catalunya: ¿cuáles son los motivos?|last=De Arístegui|first=Diego|website=Auto.Bild-Es|date=18 June 2018|access-date=14 January 2019}}

At least since 2009, the circuit is economically deficient, and in the period 2009–2018, €50.5m of losses were generated. The economic survival of the circuit is only guaranteed by large volumes of public money, which both the Provincial Deputation of Barcelona and the Generalitat de Catalunya provide in the form of grants and rinsing of losses.{{cite web|url=http://aplicacions.economia.gencat.cat/wpres/AppPHP/2017/pdf/ED_8620.pdf|title=PRESSUPOSTOS DE LA GENERALITAT DE CATALUNYA PER A L'ANY 2017|website=Generalitat de Catalunya|access-date=14 January 2019}}{{cite web|url=https://cronicaglobal.elespanol.com/business/subvenciones-circuit-barcelona-cataluna-2018_217350_102.html|title=Las subvenciones públicas de 2018 que no pudieron salvar Circuits de Cataluña|website=Crónica global-El español|date=28 January 2019 |access-date=14 January 2020}}{{cite web|url=https://www.economiadigital.es/politica-y-sociedad/circuito-montmelo-perdidas_508830_102.html|title=El circuito de Montmeló pierde otros diez millones|website=ED-Economía Digital|date=18 September 2017 |access-date=14 January 2020}}

Given these poor results, some senior officials of the Generalitat de Catalunya have considered eliminating Formula One from this Circuit. Due to the irregularities detected in the last audit, the City Council of Barcelona decided to cancel the economic grant that the circuit received until now, which has aggravated its economic survival.{{cite web|url=https://www.elmundo.es/cataluna/2019/04/11/5cae207a21efa0b7618b4615.html|title=Una auditoría halla medio millón en retribuciones irregulares en el Circuito de Montmeló|website=EL MUNDO|date=11 April 2019|access-date=14 January 2020}} Recently, some more irregularities have been detected, even by the Generalitat de Catalunya.{{Cite journal|last=Corderp|first=Dani|date=9 January 2020|title=La Generalitat halla múltiples irregularidades en la gestión del circuito de Cataluña|url=https://elpais.com/ccaa/2020/01/08/catalunya/1578517279_578922.html|journal=EL PAÍS-Cataluña}}

The circuit is located in an elevated area with respect to its environment, and without protective measures to minimize the noise pollution produced by cars, motorbikes and other vehicles. Therefore, it is a real source of acoustic disturbance, and the noise produced during many days of racing and testing during the year is noticeable for many kilometers around the circuit, especially in the adjacent municipalities, which is recognized by the Generalitat itself, the main owner of the Circuit.{{cite web|url=https://foracircuit.files.wordpress.com/2017/08/impacte-acc3bastic-circuit-aj-parets.pdf|title=Pla director urbanístic|website=Generalitat de Catalunya-Departament de Territori i Sostenibilitat.|access-date=14 January 2020}}
