Autódromo Internacional Ayrton Senna(Londrina)

The Autódromo Internacional Ayrton Senna in Londrina, Brazil, stands as a testament to the country's rich motorsport heritage. While the exact founding date is debated, the circuit gained prominence in the late 1980s and early 1990s, becoming a key venue for national racing series. Named in honor of the legendary Ayrton Senna, it carries a significant weight of expectation and history.

The track layout is a blend of high-speed straights and challenging technical sections. A long main straight leads into a tight right-hand corner, demanding precision braking and car control. The middle sector features a series of flowing bends and elevation changes, requiring drivers to maintain momentum and find the optimal racing line. The final sector is more technical, with several slower corners that reward agility and precise handling. A particularly challenging section is the "Curva do Café" (Coffee Curve), a fast, sweeping corner that tests a driver's commitment and courage.

Technically, the circuit measures approximately 3.146 kilometers (1.955 miles) in length. The track surface is asphalt, and while not overly aggressive, it can be quite demanding on tires, particularly in hotter conditions. The elevation changes are moderate but contribute to the track's overall character, adding to the complexity of finding the ideal setup. The circuit has hosted a variety of racing events, including Formula Truck, Stock Car Brasil, and Formula 3 Sudamericana. It also serves as a popular venue for local club racing and testing.

What sets Londrina apart is its blend of fast straights and technical corners, demanding a versatile car setup and a driver who can adapt quickly. The undulating terrain adds another layer of complexity. While not featuring on the international stage as frequently as some other Brazilian circuits, its tight layout and fast corners offer a unique challenge. Notable races held here include numerous rounds of the Stock Car Brasil series, which often produce close and exciting racing. While specific lap records are subject to change with different series and regulations, the track remains a significant venue for Brazilian motorsport.
