The circuit settled into a configuration of 3.707 km with 11 turns after a series of layout revisions from the original 4.200 km, 9-turn design that operated between 1967 and 1987. An outer circuit of 2.600 km with 5 turns provided a shorter option. The track sat at roughly 900 metres above sea level on the First Plateau of Paraná — high enough to affect naturally aspirated power outputs, but not at the extreme altitude of circuits further into the Andes. The climate is temperate and unpredictable; cold fronts from Antarctica arrive in any month, and rain is frequent. Drivers racing here for the first time consistently noted the contrast with the heat-management demands of the São Paulo and Rio circuits.
The layout rewarded commitment through its fast middle sector and had a characteristically wide main straight suited to the close-quarters [[stock-car-brasil|Stock Car Brasil]] field. [[formula-one|Formula One]] never visited, but the WTCC made it a regular stop from 2006 through 2012.
[[stock-car-brasil|Stock Car Brasil]] was the anchor tenant from 1980 to 2021 — a run of over four decades that made Curitiba one of the defining circuits of the national championship. The World Touring Car Championship visited from 2006 through 2012, placing the circuit on the international calendar and exposing its character to the broader touring car world. Formula 3 Sudamericana, Fórmula Truck, and TC2000 Championship rounds filled the calendar further. Bas Leinders set the Formula Nissan lap record — 1:10.182 in 2002. [[daniel-serra|Daniel Serra]] holds the Stock Car Pro record at 0:50.371, set in 2021 in what proved to be one of the final competitive seasons at the venue.
The circuit's most durable legacy is the cluster of high-level international racing drivers it produced from the Curitiba region. [[raul-boesel|Raul Boesel]] — the circuit's 2024 namesake — reached [[formula-one|Formula One]] and IndyCar. Enrique Bernoldi, [[tarso-marques|Tarso Marques]], Ricardo Zonta, Augusto Farfus, and various FIA GT and World Sportscar competitors all trace roots to the Paraná state racing ecosystem that revolved around this track. For a city of Curitiba's size, the rate of drivers reaching international competition is unusual and suggests the circuit served as a genuine developmental crucible for a generation.
The WTCC years brought visiting manufacturers — Seat, Honda, BMW — to a paddock accustomed to the national Stock Car machinery, and the juxtaposition of international touring car practice with the rougher, physically demanding Stock Car Brasil style gave the circuit a brief moment of comparative international profile that its domestic history alone would not have generated.
The 2024 renaming to Autódromo Raul Boesel came posthumously to the circuit's racing life — a civic acknowledgment of a career and a place's shared history at the moment the physical structure was already gone.
