Circuit de Spa-Francorchamps
The Circuit de Spa-Francorchamps, often called “Spa,” is a world-renowned racetrack. It sits in Belgium’s Ardennes region. People know it for its demanding layout, major elevation changes, and often changeable weather.
The current track measures 7.004 kilometres (4.352 miles). This makes it one of the longest circuits used in top-level motorsport. It has 19 corners. These include both fast, flowing turns and tricky, technical sections.
Drivers experience a significant climb and descent. The track has an elevation change of about 100 meters (328 feet). This gives it a unique “rollercoaster” feel.
Famous Sections
- La Source (Turn 1): This is a tight hairpin turn right after the start-finish line. It is a common place for cars to pass each other, especially at the start of a race. Drivers must brake precisely here and accelerate well to prepare for Eau Rouge.
- Eau Rouge and Raidillon (Turns 2-4): Many consider this the most famous part of any race circuit. It is a high-speed, uphill left-right-left series of turns. While people often call the whole section “Eau Rouge,” Eau Rouge is actually the left turn at the bottom. It gets its name from a stream beneath the track. Raidillon is the steep, uphill right-left turn that follows. Cars go through here at incredible speed, and drivers feel strong G-forces as they climb the hill.
- Kemmel Straight: After climbing Raidillon, drivers speed down this long straight section. This provides chances for cars to use the slipstream of the car ahead and reach very high speeds before braking for Les Combes.
- Les Combes (Turns 5-7): These are a series of technical medium-speed turns. They are at the end of the Kemmel Straight. Drivers need to be exact with their steering and how they use the accelerator here.
- Pouhon (Turns 10-11): This is a fast, sweeping double-left turn. It requires courage and excellent car balance from the drivers. Cars often maintain incredible speed through this part of the track.
- Blanchimont (Turns 16-17): These are extremely high-speed left turns. They lead into the final chicane. High-performance cars usually take these flat-out, demanding perfect accuracy from the driver.
- Bus Stop Chicane (Turns 18-19): This tight right-left chicane is the last set of turns before the start-finish line. It is a key spot for overtaking and often sees exciting race finishes. Drivers must brake late and accelerate strongly out of this section.
