start is in the "Tribunas" section and features a long straight with an upward inclination, then comes "S do Senna" (the Senna S) [1,2], a pair of alternating downward turns (left then right) that exhibit different attack angles and inclinations. "S do Senna" connects with "Curva do Sol" (Curve of the Sun) [3], a round-shaped large-radius left turn that leads to "Reta Oposta" (Opposite Straight) the track's longest (but not the fastest) straight. Reta Oposta is succeeded by a pair of downhill left turns that are called "Descida do Lago" (Lake's Descent) [4,5] into a short straight section that climbs up towards the back of the pit buildings. This is followed by a slow section, with small, kart-like turns and elevation changes. The first of these turns is known as "Ferradura" (Horseshoe) [6,7] downhill and right into "Laranjinha" (Little Orange) [8], another right turn and the slowest point of the circuit; the next turn leads into "Pinheirinho" (Little Pine Tree) [9], left on a plain field; then comes "Bico de Pato" (Duck Bill) [10] a right turn with a tight hairpin like shape; and then "Mergulho" (Dive) [11], a constant-radius left-hand turn that slings the driver straight into a harder left at "Junção" (Junction) [12]. Turn [13] "Café" (Coffee), is a left up-hill kink and marks the start of the long top-speed section. Rising up through "Subida dos Boxes" (Up to the Pits) [14], the driver encounters a long uphill left turn with a gradient of 10% that demands a lot of power from the cars. At the end of it comes Arquibancadas (Bleachers) [15], a wide high velocity left turn that connects to the "Tribunas" straight to complete the final section of the track. The series of left turns from the exit of "Junção" all the way to Turn 1 is typically taken at full throttle and treated as a long straight. This section is one of the longest full-throttle stretches on the Formula 1 calendar, and thus demanding of the engine's reliability. Other notable stretches of this nature are the "Rettifilo Tribune" straight at Autodromo Nazionale di Monza and the Kemmel Straight at Circuit de Spa-Francorchamps.
