Spa’s current Grand Prix Circuit layout has been listed as in use since 2007.
The modern configuration emerged from a major renovation completed before Formula One returned to Spa-Francorchamps for the 2007 Belgian Grand Prix. The work cost about €19 million and altered the pit-lane and start-finish areas. La Source was moved forward, while the Bus Stop chicane was repositioned toward Blanchimont.
The answer can be confused with earlier layout dates. The circuit used a Grand Prix layout from 2004 to 2006, and another version was listed for 1995–2003. Those dates describe previous configurations, not the current post-renovation arrangement.
Spa’s newer layout is much shorter than the original public-road course, but it retains the track’s defining character: dramatic elevation changes, long high-speed sections and famously unpredictable weather in Belgium’s Ardennes region.
