Circuit de Spa-Francorchamps

The original 14.982-kilometre (9.309 mi) track layout

In 1918, German headquarters were in Spa, and in 1919, the Treaty of Versailles separated the Eupen-Malmedy region from Prussia and the German Empire. Between January and June 1920, a plebiscite was held, without a secret ballot and under other questionable circumstances. As a result, the Transitional Government prepared for the unification of Eupen-Malmedy with Belgium in June 1925.

Jules de Thier, owner of the Liège newspaper La Meuse, was looking for a site to host a race, and following a meeting at the Hotel des Bruyères in Francorchamps, with burgomaster Joseph de Crawhez and racing-car driver Henri Langlois van Ophem, it was decided that the roads from Spa-Francorchamps to the former German Malmedy, to Stavelot, and back towards Francorchamps constituted an ideal triangle-shaped circuit with few tight corners and long fast sections.[4] Eau Rouge creek was the Belgian-German Empire border[5][6] until 1920, with the Ancienne Douane customs office being rather recent than ancient. After passing through former German Bürnenville, the track crossed the former border again halfway on the road between Malmedy and Stavelot, at the junction of the Meiz road. In Stavelot, there was a sharp right-hander, later replaced with a sweeping bypass.

The track's inaugural race was planned for August 1921, but was cancelled when only one driver entered.[4] The first car race was held at the circuit in 1922, and 1924 saw the first running of the now famous 24 Hours of Francorchamps race.[4] The circuit was first used for Grand Prix racing in 1925.[4]

The original Spa-Francorchamps circuit was essentially a speed course, with drivers managing higher average speeds than on other road race tracks. At the time, the Belgians took pride in having a very fast circuit, and to improve average speeds, in 1939 the former Ancienne Douane slow uphill U-turn after the bottom of the Eau Rouge creek valley was cut short with a faster sweep straight up the hill, called the Raidillon. In public traffic until 2000, at Eau Rouge, southbound traffic was allowed to use the famous uphill corner, while the opposite downhill traffic had to use the old road and U-turn behind the grandstands, rejoining the race track at the bottom of Eau Rouge. Around 2001, a new bypass road N62c was built to the East, and the track was closed to the public as the road from Stavelot to Blanchimont became a cul-de-sac.

The old race track continued through the fast Kemmel curves (straightened in 1979) to the highest part of the track (104 m (341 ft) above the lowest part), then went downhill into Les Combes, a fast, slightly banked downhill left-hand corner towards Burnenville, passing this village in a fast right hand sweep. Near Malmedy, the Masta straight began, which was only interrupted by the Masta Kink between farm houses before arriving at the town of Stavelot. Then, the track progressed through an uphill straight section with a few bends called La Carriere, going through two high-speed turns (the former being an unnamed right-hand turn, and the latter named Blanchimont) before braking very hard, for the Bus Stop chicane that was added later, and for La Source hairpin, that rejoined the downhill start finish section (as opposed to today where the start–finish section is before La Source).

Spa is located in the Belgian Ardennes countryside, and the long old circuit was, and for most parts still is, used as an everyday public road, and there were houses, trees, electric poles, fields and other obstacles located right next to the track. Before 1970, there were no safety modifications of any kind done to the circuit and the conditions of the circuit were, aside from a few straw bales, virtually identical to everyday civilian use. Former Formula One racing driver and team owner Jackie Oliver was quoted as saying "if you went off the road, you didn't know what you were going to hit".[7]

Spa-Francorchamps was the fastest road circuit in Europe at the time, and it had a reputation for being dangerous and very fast – it demanded calmness from drivers, and most were frightened of it. The old Spa circuit was unique in that speeds were consistently high with hardly any let-up at all for three to four minutes. This made it an extraordinarily difficult mental challenge, because most of the corners were taken at more than 290 km/h (180 mph) and were not quite flat – every corner was as important as the one before it. If a driver lifted the throttle more than expected, then whole seconds, not tenths, would be lost. The slightest error of any kind carried multiple harsh consequences, but this also worked inversely: huge advantages could be gained if a driver came out of a corner slightly faster.

Like the Le Mans circuit, which also ran on public roads, Spa became notorious for fatal accidents. At the 1960 Belgian Grand Prix, two drivers, Chris Bristow and Alan Stacey, were killed within 15 minutes (although Stacey's accident was caused by a bird hitting him in the face) and Stirling Moss had crashed at Burnenville during practice and was severely injured. When Armco crash barriers were added to the track in 1970, deaths became less frequent, but the track was still notorious for other factors. The Ardennes forest had very unpredictable weather and there were parts where it was raining and the track was wet, and other parts where the sun was shining and the track was completely dry. This factor was a commonality on long circuits, but the unpredictable weather at Spa, combined with the fact that it was a track with all but one corner being high-speed, made it one of the most dangerous race tracks in the world (if not the most). As a result, the Formula 1 and motorcycle Grands Prix and 1000 km sportscar races saw smaller than usual fields at Spa because most drivers and riders feared the circuit and did not like racing there. Multiple fatalities during the 1973 and 1975 24 Hours of Spa touring car races more or less sealed the old circuit's fate, and by 1978, the last year Spa was in its original form, the only major races held there were the Belgian motorcycle Grand Prix and the Spa 24 Hours touring car race; the 1000 km World Sportscar Championship race no longer took place after 1975 and did not come back until 1982.

In 1969, the Belgian Grand Prix was boycotted by the F1 drivers because of the extreme danger of Spa. There had been ten car racing fatalities in total at the track in the 1960s, including five in the two years previous. The drivers demanded changes made to Spa which were not possible on short notice, so the Belgian Grand Prix was dropped that year. Armco barriers were added to the track and sections of it were improved (especially the Stavelot and Hollowell sections), just like they had been added for the 1969 Le Mans race. One last race there the following year on the improved track was still not satisfactory enough (even after a temporary chicane was added at Malmedy just for that race) for the drivers in terms of safety, and even with the chicane, the drivers averaged over 240 km/h (150 mph) during the race. For the 1971 race, the track owners and authorities had not brought the track up to date with mandatory safety measures, and the race was cancelled. Formula One would not return to Spa until 1983 on the modern track.

The Masta Kink "was by far the most difficult corner in the world", according to Jackie Stewart,[8] requiring skill and bravery in equal measure to get it right. After a long run from Malmedy, the cars would reach top speed before having to negotiate Masta, a high speed left-right chicane, and a good exit speed was vital as it was followed by another long straight run to Stavelot. This was a very fast and very dangerous corner, as it was situated right in the middle of two long unbroken straights, both about 1.5 mi (2.4 km) long. The speed in this sector could reach 310 km/h (190 mph).

Masta was removed from F1 racing after the 1970 season. Jackie Stewart's crusade to improve safety in racing was set in motion by his crash there in 1966, when his BRM ended upside-down in a ditch near a farmhouse on the outside of the corner, with fuel gushing out of the tank onto Stewart, who had broken ribs. At this point, many of the Formula One drivers disliked Spa (including Stewart and Jim Clark, who had some of his greatest wins there) because of the immense speeds that were constant on the track. While he was spectating at the 1972 12 Hours of Sebring, Stewart attempted to organise a boycott of the Spa 1000 km race that year, a move that was not respected by many of the drivers, because Spa was still popular with racing drivers outside of Formula One. Stewart later described the old Spa circuit in 1986 as being as "ferocious as a tiger", and he later described Masta in an interview in 2011 as perhaps the hardest corner on any racetrack he raced on in his career; even more so than Eau Rouge.[9]

Another particularly gruesome story comes from the 1972 24-hour touring car race.[10] During one of his pit stops at night, Hans-Joachim Stuck shouted to his co-driver Jochen Mass over the noise from the cars that he should "look out for body parts at the Masta Kink". Mass arrived there expecting to see pieces from cars all over the road but was appalled to discover it was in fact the remains of a marshal.[11]

After Masta, and at the end of the subsequent Hollowell Straight, there used to be a sharp hairpin at the entrance to the town itself, which was later bypassed by a quicker, banked right hand corner. Another fast section of road in the forest leads to Blanchimont. Here, the new short Grand Prix track of 1979 joins the old layout.

Eighteen Formula One World Championship Grands Prix were run on the Spa-Francorchamps circuit's original configuration, which was boycotted by F1 in 1969,[12] before the revised circuit banished it to the history books in 1979. The lap record of the old triangle-shaped track is 3 minutes and 13.4 seconds, held by the French driver Henri Pescarolo, driving a Matra at the 1973 Spa 1000 km World Sportscar Championship race at an average speed of 262 km/h (163 mph), but the fastest ever recorded time of the old Spa circuit was the pole position time for the same race—3 minutes and 12.7 seconds by Jacky Ickx in a Ferrari 312PB.

Over the years, the Spa course has been modified several times. The track was originally 14.982 km (9.309 mi) long, but after World War II, the track underwent some changes. In 1930, the chicane at Malmedy was eliminated and bypassed, making the course even faster, but the chicane was re-installed in 1935, albeit slightly different. In 1939, "Virage de l'Ancienne Douane" was eliminated and cut short, thus giving birth to the Eau Rouge/Raidillon uphill sweeping corner. In 1947, the chicane at Malmedy was again eliminated and bypassed, and was made part of the Masta Straight. The slight right-hander that was originally Hollowell (the corner before Stavelot after the second Masta Straight) was eliminated. And finally, instead of going through a slight left-hander that went into the town of Stavelot and a sharp right-hander at a road junction in Stavelot, a shortcut was built that became a very fast, very wide right-handed turn that bypassed Stavelot. All these changes made the final configuration of the old Spa circuit 14.100 km (8.761 mi) long, and also made Spa the fastest open road circuit in the world. In the final years of the old circuit, drivers could average 240 km/h (150 mph). The biggest change, however, saw the circuit being shortened from 14.100 to 6.947 km (8.761 to 4.317 mi) in 1979. The start/finish line, which was originally on the downhill straight before Eau Rouge, was moved to the straight before the La Source hairpin in 1981. Like its predecessor, the new layout is still a fast and hilly route through the Ardennes where speeds in excess of 330 km/h (210 mph) can be reached. Since its inception, the place has been famous for its unpredictable weather, where drivers are confronted with one part of the course being clear and bright while another stretch is rainy and slippery.

The "Raidillon" in the Eau Rouge valley

Red water ("Eau rouge" in French) on the banks of the river close to the circuit

The most famous part of the circuit is the Eau Rouge and Raidillon combination. Having negotiated the La Source hairpin, drivers race down a straight to the point where the track crosses the Eau Rouge stream for the first time, before being launched steeply uphill into a sweeping left-right-left series of corners with a blind summit. Properly speaking, the Eau Rouge corner is only the left-hander at the bottom. The following right-hander that leads steeply uphill, which was introduced in 1939 to shortcut the original Ancienne Douane hairpin, is called Raidillon. The corner requires an amount of skill from the driver to negotiate it well and the long Kemmel straight ahead produces good overtaking opportunities for drivers at the following "Les Combes" corner. The corner was tighter and narrower before 1970, allowing drivers to take the corner faster.

Double F1 World Champion Fernando Alonso explained:

"...You come into the corner downhill, have a sudden change [of direction] at the bottom and then go very steep uphill. From the cockpit, you cannot see the exit and as you come over the crest, you don't know where you will land. It is a crucial corner for the timed lap, and also in the race, because you have a long uphill straight afterwards where you can lose a lot of time if you make a mistake. But it is also an important corner for the driver's feeling. It makes a special impression every lap, because you also have a compression in your body as you go through the bottom of the corner. It is very strange – but good fun as well."[13]

A challenge for drivers has always been to take Eau Rouge/Raidillon flat out. Touring cars can take the corner at 160–180 km/h (99–112 mph), and Formula One cars at over 300 km/h (190 mph) due to high downforce.[14] World Champion Jacques Villeneuve once spoke of the effects of downforce, saying that to get through the corner the drivers have to drive faster, because downforce increases the faster a race car goes. Without lifting the throttle through Eau Rouge, a car would be flat out from La Source, along the Kemmel straight to Les Combes, a total distance of 2.015 km (1.252 mi).

A loss of control through this section can often lead to a very heavy shunt, as usually the rear end of the car is lost and the resulting impact is often lateral. Several famous racing drivers have crashed while driving through Eau Rouge/Raidillon, including Stefan Bellof in a Porsche sportscar, Guy Renard during the 1990 24h of Spa-Francorchamps in a Toyota Corolla GT, and Alex Zanardi in a season-ending crash during a practice session of the 1993 Belgian Grand Prix in a Lotus. Jacques Villeneuve suffered a spectacular crash at the top of Raidillon in qualifying during the 1999 Belgian Grand Prix which he described as "My best-ever crash". His teammate Ricardo Zonta followed Villeneuve by having a similar accident later in practice, leading cartoonist Jim Bamber to show BAR boss Craig Pollock telling Zonta: "Jacques is the quickest through Eau Rouge, so go out there and do exactly what Jacques does…" It was revealed later that Villeneuve and Zonta had a personal bet to see if either could take the corner flat out.[15]

Following the deaths of Roland Ratzenberger and Ayrton Senna at Imola in 1994, the following F1 races saw the introduction of chicanes made up from stacked tyres. The entry to Eau Rouge was obstructed in such a way in 1994, although it was returned to its previous configuration the following year. The corner was slightly modified for the 2002 Belgian Grand Prix.

When fans first got to see the course configuration at the start of the weekend of the 2005 Turkish Grand Prix, they noted that an uphill kink on the back straight was very similar to Eau Rouge; the kink was therefore jokingly dubbed "Faux Rouge" (a pun on the name of the original Spa corner using the French word "faux", meaning "false").[16]

The Blanchimont high-speed left-hand turn, present in both the old 14.100 km (8.761 mi) circuit and the new, shorter, 7.004 km (4.352 mi) track, is the final sweeping corner of the track before the chicane, which leads to the pit straight.

This turn and the approach to it have been the scene of serious accidents over time, the most recent being in 2001, when Luciano Burti lost the front wing of his Prost due to a clash with Eddie Irvine's Jaguar, losing front downforce and steering, leaving the track at 298 km/h (185 mph) and piling into the tyre wall, the impact knocking him out and burying the car into a mound of tyres. Problems have also occurred in lower classes of racing with Tom Kristensen having a very violent crash in a Formula 3000 car in 1997 after running wide on the entry to the Blanchimont turn and subsequently hitting the wall, throwing the monocoque back out in the middle of the track, where it was hit by numerous cars before coming to a complete halt.[17]

The run-off area is narrower than in other turns taken at this speed, and behind the protective barriers there is a 7–8 metre drop. This is the first turn taken by the cars after the new track rejoins the route of the old 14.100 km (8.761 mi) track. Blanchimont was also the scene where in 1992 after Érik Comas had crashed heavily during Friday's session, Ayrton Senna stopped, disembarked his car and sprinted to help the injured driver, with other cars driving past at racing speeds.

From the 2018 Belgian Grand Prix turn 11 has been called the Jacky Ickx corner as a tribute to his career.[18] The corner was formerly known by most drivers as "speakers corner" because the circuit's public address announcer could see the cars for the first time after the cars disappeared into the forest past Raidillon. There are two versions of Jacky Ickx as of 2022, the car turn and a turn inside of it for motorcycles.

With a new financial backer, the renovation started on 6 November 2006 and finished in May 2007, costing around €19 million.[20] Formula 1 returned to Spa for 2007, with a modified track layout. The Bus Stop chicane was moved back towards Blanchimont and the La Source hairpin moved forward. This allowed more space for the new pit lane, and gave a longer start/finish straight.

New asphalt runoff was added to the inside and outside of Les Combes for the 2010 race, in line with the prevailing trends at other Formula One circuits. Prior to the 2013 race, drainage grooves were cut into the asphalt on the start–finish straight, underneath the first 11 grid slots. Drivers were initially concerned that this would affect grip at the start.

In Spa Francorchamps' tenure as a permanent racing facility, after it was removed from the public road network in 2000, there have been multiple accidents in the Eau Rouge/Raidillon combination. In the day and age where safety is paramount to many racing organizations and governing bodies like the Fédération Internationale de l'Automobile, these crashes, of which some noteworthy ones are listed below, opened up public debate whether the Eau Rouge/Raidillon combination was deemed unsafe. Criticism centred around the nature of the tyre barrier and run-off area of Raidillon, which tended to bounce out-of-control cars back onto the track rather than collect them.[21]

In October 2020 the circuit announced that gravel traps would be placed at La Source, Raidillon, Blanchimont, Les Combes and Stavelot. The runoff areas of some corners including Raidillon would be expanded. It was part of an €80 million upgrade to the circuit that would make it able to hold motorcycle races. The upgrade will also include a grandstand at the top of the Eau Rouge/Raidillon hill. The upgrades were completed in March 2022, ready for the FIM Endurance World Championship race, due to be held in June. The circuit is also shortened to 6.985 km (4.340 mi), as Jacky Ickx corner is bypassed in favour of a shorter section with more runoff for motorcycles.[22][23]

During the Formula 2 feature race in late August, a serious incident between Anthoine Hubert and Juan Manuel Correa occurred shortly after Raidillon on the Kemmel Straight. As the second lap began, Trident driver Giuliano Alesi lost control of his car as he climbed the Raidillon curve due to a puncture he had received earlier, causing his car to spin and hit the left wall of the circuit, tearing off his rear wing and spreading debris onto the track. As another Trident driver, Ralph Boschung reached the crest of Raidillon, he slowed down and moved towards the run-off area to avoid Alesi's damaged car and the field of debris. Hubert, who was following Boschung closely and had no view of what had happened to Alesi, moved right to avoid Boschung's slowing car, clipping Boschung's right rear wheel with his front wing. Hubert's car crashed into the tyre barrier on the right side of the track at an acute angle and was deflected sideways into the path of Charouz driver Juan Manuel Correa, who struck it on the left side in the driver seat area.[24]

The incident resulted in the death of Hubert and serious injury to Correa with the feature race being abandoned and the scheduled sprint race a day later being cancelled too, whilst the Formula 1 Belgian Grand Prix went ahead.

During the qualifying session of the W Series, rain started to fall, affecting the grip. This caused a serious incident that involved six cars crashing into each other. Sarah Moore was the first driver to lose control of her car, spinning into the barrier at Raidillon. Abbie Eaton also lost the car and spun into the same barrier. She bounced back into Moore at low speed. Beitske Visser lost the rear end, spun around and went straight into Eaton and Moore, causing Eaton to become airborne. Ayla Agren did the same as Visser, spinning and running into Moore and an airborne Eaton. Belén García then hit all four cars, causing Visser to become airborne and mount the tyre barrier. The final car of Fabienne Wohlwend then hit Beitske Visser head on, causing Visser to spin into the track and roll over.[25][26] The incident ended with cars all over the track and run off areas. All drivers were checked as a precaution, and Visser and Agren were sent to hospital for x-rays and further checks.[27] Eventually, all drivers were cleared and unharmed.[28]

Just one day after the W Series crash, Formula One held its qualifying session in heavy rain. In the third segment of qualifying, many drivers were complaining that the conditions were not safe and that the session should be delayed or red flagged. Lando Norris then had a snap of oversteer, and subsequently corrected but then aquaplaned into the tyre barrier at Raidillon. His McLaren then spun into the track while crossing the racing line.[29][30] Norris was taken to hospital for x-rays, but was cleared to race the next day.[31]

After this crash and the W Series incident just a day before, drivers from all series were calling for changes to that section of the track. Jack Aitken, who a month earlier suffered a broken collarbone and fractured vertebra after a crash at Raidillon in the 2021 24 Hours of Spa, said "everyone has gotten the picture of what needs changing"[32] on social media, regarding the W Series crash. Zhou Guanyu stated "Eau Rouge corner in Spa needs to making a change,"[33] while Pietro Fittipaldi said "they need to do something to Eau Rouge to make it safer.”[34] Carlos Sainz Jr. insisted the "corner maybe needs a bit of fine-tuning still."[35] Sacha Fenestraz, Jake Hughes, Daniel Ricciardo and Toto Wolff all agreed changes need to be made immediately to make the circuit safer.[36][37][38][39]

On 1 July 2023, a multi-car crash in the second race of the 2023 Formula Regional European Championship resulted in the death of Dutch racing driver Dilano van 't Hoff.[40] The crash happened at the exit of the Raidillon corner, at the beginning of the Kemmel straight. Dilano lost control of his MP motorsport car at the exit of the Raidillon corner, hitting the barrier on the left side of the track. The car was bounced back in the middle of the track, after which Adam Fitzgerald hit the cockpit of the car on drivers right side at full speed. Poor visibility due to heavy rain prevented the Irish racing driver from reacting in time to avoid the collision. Other drivers involved in the crash were Joshua Dufek, Emerson Fittipaldi Jr., and Enzo Scionti.

Multiple other incidents have happened at the Eau Rouge/Raidillon section of the circuit. These include crashes for Kevin Magnussen in 2016, where he managed to walk away with only minor injuries;[41] Pietro Fittipaldi in 2018, where he broke his leg[42] and Jack Aitken in 2021, where he broke his collarbone.[43] In May 2023, during the Franco Fun Festival, the driver Olivier Parigi, who was driving the car #508, crashed and died. According to a statement of the organizers "Excessive speed and then a loss of control on his own in the Speaker Corner. Minor accident but a chain of circumstances after breaking away in the car were fatal to our friend during his stay in Liège hospital."[44]

Ahead of the 2022 FIM EWC 24H Spa EWC Motos race and 2022 F1 Grand Prix, the circuit underwent a major facility and safety facility redevelopment which had been planned since 2020. Extra run-off was added to the Eau Rouge/Raidillon part of the course – changes made in response to several big accidents in recent years at that section of the track, including the fatal accident of Anthoine Hubert during the 2019 Spa-Francorchamps Formula 2 round.[45] In addition, gravel traps were added to and modified at various corners around the circuit including: La Source, Les Combes, Speaker's Corner, Pouhon, Stavelot and Blanchimont.[46][47] The track has also been resurfaced for this year's event altering track grip levels, with Max Verstappen the first driver to run a Formula One car around the renovated circuit in a Red Bull RB7.[48] Jarno Zeffelli, head of Dromo Circuit Design, the company who carried out the renovations, revealed twenty possible different iterations of Eau Rouge were evaluated, with the selected iteration chosen with the help of form of ex-Formula One drivers Thierry Boutsen and Emanuele Pirro and fine tuned with simulations for Formula One and GT cars.[49]

Spa-Francorchamps is part of the 2023 Formula 1 calendar.[50]
