The Circuit de Spa-Francorchamps is the venue of the Formula One Belgian Grand Prix and the Spa 24 Hours endurance race. It is also home to the all Volkswagen club event, 25 Hours of Spa, run by the Uniroyal Fun Cup. It is considered to be one of the most challenging race tracks in the world, mainly due to its fast, hilly and twisty nature. Spa is a favourite circuit of many racing drivers and fans.^[1]

The track

The triangle

Designed in 1920 by Jules de Their and Henri Langlois Van Ophem^[2], the original triangle-shaped course used public roads between the Belgian towns of Francorchamps, Malmedy and Stavelot. The track was intended to have hosted its inaugural race in August 1921, however this event had to be cancelled as there was only one entrant^[2]. The first car race was held at the circuit in 1922, and two years later saw the first running of the now famous 24 Hours of Francorchamps race^[2]. The circuit was first used for Grand Prix racing in 1925^[2].

The previous 14km track layout

The old Spa circuit was essentially a speed course with drivers managing much higher average speeds than on other race tracks- a factor that made Spa very popular from its inception. Back then, the Belgians took pride in having a very fast circuit, and to improve average speeds, the former slow uphill U-turn at the bottom of the Eau Rouge creek valley, called the Ancienne Douane, was cut short with a faster sweep straight up the hill, called the Raidillon. Until 2000, it was possible to travel over the race track when it was still a public road. 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 grand stands, rejoining the race track at the bottom of Eau Rouge.

The old race track continued through the now-straightened Kemmel curves to the highest part of the track, then went downhill into Les Combes, a fast, slightly banked downhill left hander towards Burnenville, passing this village in a fast right hand sweep. Near Malmedy, the Masta straight began, which was only interrupted by the fast Masta Kink between farm houses before arriving at the town of Stavelot. Then the track blasted through an uphill straight section with a few kinks called La Carriere, going through 2 ultra-fast turns (an unnamed right-hand turn and then Blanchimont) before braking very hard for the La Source hairpin, and that rejoined the downhill start finish section as opposed to today where the start-finish section is before La Source.

Like the Nürburgring, Spa became notorious for fatal accidents, as there were many deaths each year at the ultra-fast track, especially at the 1960 Belgian Grand Prix where 2 drivers, Chris Bristow and Alan Stacey were both 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 was added to the track in 1970, deaths became less frequent there 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 weather at Spa was always and more unpredictable than other long circuits, combined with the fact that it was an ultra-high speed track with all but 2 of the corners (La Source and Eau Rouge) being high-speed made it one of, if not the most dangerous race track in the world. 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 race.

In 1969, the Belgian Grand Prix was boycotted by F1 because of the extreme danger of Spa. The drivers demanded changes made to Spa which were not possible on short notice, so the Belgian Grand Prix was dropped that year. Armco was added to the track and sections of it were improved (especially the Stavelot and Holowell sections), just like Armco had been added for the 1969 Le Mans race. One last race there the following year on the improved track still was not satisfactory enough for the drivers in terms of safety. F1 would not return to Spa until 1983 on the modern track.

Masta Kink

The Masta Kink was one of the most fearsome sections on any race track in the world, 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 because it was situated right in the middle of 2 very long unbroken straights both about 1½ miles long (2.4 km).

Masta was lost to F1 racing after the 1970 race. 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 the cellar of the farmhouse on the outside of the corner, with fuel gushing out of the tank onto Stewart, who had broken ribs to add to his misery. At this point, many of the Formula One drivers disliked Spa (including 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 organize a boycott of the Spa 1000km race that year, a move that was not respected by many of the drivers. ^[3]

The original 15km Spa layout

Another particularly gruesome story comes from the 1972^[4] 24 hour touring car race. During one of his pitstops at night, Hans-Joachim Stuck shouted to his co-driver Jochen Mass over the noise that he should "look out for body parts at the Masta Kink". Mass arrived there expecting to see bits of car all over the road but was appalled to discover it was in fact bits of a marshal.^[5]

After Masta, and at the end of the subsequent Holowell 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 , before the revised circuit banished it to the history books in 1979. The lap record of the old triangle-shaped track is held by the French driver Henri Pescarolo, at an average speed of 262 km/h (163 mph).

New layout

The modern circuit as seen from the air.

Over the years, the Spa course has been modified several times. The track was originally 15 km (9.3 mi) long, but after World War II, the track had some changes. The uphill U-turn right after the famous Eau Rouge corner called "Virage de Ancienne Douane" was eliminated and cut short, thus giving birth to the Radillon uphill sweeping corner. The sudden right-hander at Malmedy was eliminated and bypassed, and was made part of the Masta Straight. The slight right-hander that was originally Holowell (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 km (8.7 mi) long. All these changes made Spa the fastest open road circuit in the world, and in the final years of the old circuit, drivers could average 150+ mph (245 km/h) on the circuit. The biggest change, however, saw the circuit being shortened from 14 km (8.7 miles) to 7 km (4.35 miles) 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. Like its predecessor the new layout still is a fast and hilly route through the Ardennes where speeds in excess of 330 km/h (205 mph) can be reached. Since inception, the place has been famous for its unpredictable weather. Frequently drivers are confronted with one part of the course being clear and bright while another stretch is rainy and slippery.

The circuit probably demonstrates the importance of driver skill more than any other in the world. This is largely due to the Eau Rouge and Blanchimont corners, both which need to be taken flat out to achieve a fast run onto the straights after them, which aids a driver in both a fast lap and in overtaking.

The "Raidillon" in the Eau Rouge valley

Eau Rouge

The most famous part of the circuit is the Eau Rouge / 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 collection 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 hairpin "Ancienne Douane", is called "Raidillon". The corner requires a large amount of skill from the driver to negotiate well and the long straight ahead often produces good overtaking opportunities for the best drivers at the Les Combes corner.

The 2005 and 2006 F1 World Champion Fernando Alonso explains: "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." ^[6]

The challenge for drivers has always been to take Eau Rouge-Raidillon flat out. Regular touring cars can take the corner at 160–180 km/h, Formula One at over 300 km/h.^[7] This is due to the huge amount of downforce on the cars. World Champion Jacques Villeneuve once spoke of the effects of downforce saying that to get through the corner they have to go faster as the faster the car is going the more downward force there is, thus explaining the phenomenon of Eau Rouge flat out.

Still, a loss of control in this section often leads to very heavy shunt as usually the rear-end of the car is lost and the impact is most of the times lateral. Eau Rouge has claimed several victims over the years, including Stefan Bellof in a Porsche sportscar, Guy Renard during the 24h of Spa-Francorchamps in 1990 in a Toyota Corolla GT and also caused Alex Zanardi's in 1993 and Jacques Villeneuve's spectacular off in qualifying in 1999, which he described as "My best-ever crash", followed by his team-mate Ricardo Zonta's similar accident, 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…"

Following the deaths of Roland Ratzenberger and Ayrton Senna at Imola in 1994, the following F1 races saw the introduction of chicanes made of piles of tyres. The entry to Eau Rouge was obstructed in such a way in 1994, although it was returned to its previous glory the following year. The corner was slightly modified for 2002, but still retains its character.

Testimony to the fame and beloved character of the Eau Rouge corner can be found in fan reaction to the Istanbul Park circuit in Istanbul, Turkey. When fans first got to see the course configuration at the start of the weekend of the 2005 Turkish Grand Prix, many noted that an uphill kink on the back straight was very similar to Eau Rouge; many jokingly dubbed the kink "Faux Rouge" (a pun on the name of the original Spa corner using the French word "faux", meaning "false").

Blanchimont

The Blanchimont turn is one of the most fearsome turns in Formula One. This high-speed left-hand turn, present in both the old 14 km circuit and the new, shorter, 7 km track, is the final sweeping corner of the track before the Bus Stop chicane, which leads to the pit straight.

This turn and the approach to it have caused 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 185 mph (298 km/h) 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 effectively throwing the monocoque back out in the middle of the track, where it was hit by numerous cars before coming to a complete halt.^[8]

The run-off area is narrower than in other turns taken at this speed, plus the fact that behind the protective barriers there is a 7-8 meter drop. This is the first turn taken by the cars after the new track rejoins the route of the old 14 km track. Blanchimont was also the scene where in 1992 after Erik 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.

Recent turmoil

Due to the introduction of a new legislative order in Europe, new bans in tobacco advertising have been imposed, and as a special case, Formula One is facing a major threat regarding this point. Due to these political and legislative circumstances, Grand Prix in this circuit was left out of the 2003 calendar as a response to the internal tobacco legislation in Belgium. The event was tagged as a World Class event within the national senate, and thus it was saved for the 2004 Formula One season. The section known as the Bus Stop chicane was reprofiled for 2004 with an additional sweep to the right.

Spa was dropped from the Formula One calendar in 2006. The organiser of the event went bankrupt in late 2005, and therefore the planned improvements to the race track and paddock had not yet been made. The Wallonia government stepped in and provided the necessary funds, but too late for the 2006 race to take place.

As of 2007, tobacco advertising bans limited the number of sponsors from the industry finding the sport appealing. As of 2010, only the Scuderia Ferrari Marlboro still has tobacco branding. By comparison, in 2003, five teams—half of the teams competing—had tobacco branding. Scuderia Ferrari Marlboro recently dropped the Marlboro "stripes" from their race cars after accusations of it being linked to cigarette advertsing. The team still have the "stripes" on all team gear.

Redevelopment for 2007 season

With a new financial backer, the renovation started on November 6, 2006 and finished in May 2007, costing around €19 million.^[9]

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. The modifications gave a longer start/finish straight.
