Track map and layout
Autódromo Vegas de Quilaco is a short, twisty 1.470 km circuit a few kilometres north of the town of La Unión in Chile's Los Ríos Region, with barely any straights beyond the short run past the start/finish line, a layout that tends to produce close, frenetic club racing. It was originally cut as a dirt track by local volunteers in 1969 and was not paved with asphalt until 1994. The circuit is now more commonly known locally as Autódromo Sergio Wagner Rosas, honouring the founder who conceived the project, who died in 2012.

Events and race weekends
In its stronger years the circuit hosted a round of the Chilean Formula 3 national championship and its own 100 Kilómetros de Quilaco endurance race. A deteriorating track surface in more recent years has reduced activity to amateur club racing rather than national-level championship dates, and no confirmed recurring major series currently uses the venue.
Getting there and parking
The circuit sits about 5 km north of La Unión, a small town in the Los Ríos Region of southern Chile, reached via local routes T-60 and T-712. There is no rail or scheduled public transport directly to the track; a car is the practical way to reach it.

History of Autódromo Vegas de Quilaco (Autódromo Sergio Wagner Rosas)
Carved out by volunteers
Autódromo Vegas de Quilaco began in 1969, when local racing enthusiast Sergio Wagner Rosas persuaded engineers building the nearby IANSA sugar refinery to lend heavy machinery to a team of volunteers, who used it to carve a dirt track out of farmland a few kilometres north of La Unión, in what is now Chile's Los Ríos Region. What started as a rough, informal circuit gradually became a fixture of motorsport in Chile's south, drawing club racers from across the region for over two decades before it saw any real infrastructure investment.
Paving and a national spotlight
The circuit was finally paved with asphalt in 1994, upgrading it to a proper permanent facility for the first time. In the years that followed it hosted a round of the Chilean Formula 3 national championship and established its own long-distance event, the 100 Kilómetros de Quilaco endurance race, giving this modest rural circuit a period of genuine national relevance within Chilean motorsport.
A quieter present, honouring its founder
Sergio Wagner Rosas, the circuit's founding figure, died in 2012, and the venue is now more commonly known locally as Autódromo Sergio Wagner Rosas in his memory. In the years since, a deteriorating track surface has limited activity mostly to amateur club events rather than national championship racing, leaving the circuit as a quieter but still-used piece of grassroots Chilean motorsport history. It should not be confused with the commune of Quilaco in the Biobío Region, further north; despite the shared name, the circuit itself sits near La Unión in the Los Ríos Region.
