Turn 1: Elf (Turn 1) Named for the French oil company Elf. The main braking zone at the end of the pit straight and the lap's primary overtaking point. Nico Rosberg passed Lewis Hamilton around the outside here on lap 1 of the 2016 race.
Turn 2: Turn 2 The second part of the opening left-right complex just after Turn 1. Sources differ on its name, one Spanish sponsor list calling it Abolafio while a corner-names guide treats it as unnamed. Kimi Raikkonen was forced off trying to pass Carlos Sainz here in 2016.
Turn 3: Renault (Turn 3) Named for the French carmaker Renault and called the Curvon Renault in Spain. A long, near flat-out right-hander that loads roughly 4G and is one of the lap's hardest corners on tyres and aero balance.
Turn 4: Repsol (Turn 4) Named for the Spanish energy company Repsol, a sweeping right-hander likened to Monza's Parabolica. On lap 1 of the 2016 race the two Mercedes of Hamilton and Rosberg collided here and both retired, handing Max Verstappen his maiden win on his Red Bull debut.
Turn 5: Seat (Turn 5) Named for the Spanish carmaker SEAT, a slow second-gear left-hander that drops downhill right after Repsol and is easy to overdrive on worn rears.
Turn 6: Turn 6 An unnamed left-hand kink, taken essentially flat and described as barely registering as a corner for an F1 car.
Turn 7: Wurth (Turn 7) The first part of an uphill medium-speed left-right chicane, named for the German industrial supplier Wurth, though sources differ on whether the name covers Turn 7 alone or the whole 7 to 8 sequence.
Turn 8: Turn 8 The corner completing the uphill chicane, with a large kerb on its apex. One Spanish source names it separately for Placo Saint-Gobain while a corner guide groups it under Wurth with Turn 7.
Turn 9: Campsa (Turn 9) Named for the former Spanish state oil company Campsa. A signature corner, a very fast sixth-gear right-hander taken almost blind over its crest. Heikki Kovalainen left the track here at around 240 km/h in 2008 after a wheel-rim failure.
Turn 10: La Caixa (Turn 10) Named for the Spanish bank La Caixa, a heavy-braking third-gear left-hander at the end of the back straight and one of the lap's best overtaking spots. It was deliberately tightened in 2004 to create an overtaking chance.
Turn 11: Banc Sabadell (Turn 11) Named for the Spanish bank Banco Sabadell, a transition corner building speed toward the final sector. Sources disagree on its direction, one calling it a left kink and another a right-hand section.
Turn 12: Europcar (Turn 12) Named for the French car-rental firm Europcar, a long slow-to-medium right-hander before the fast final sequence. Moto2 rider Luis Salom died in a 2016 practice crash here, after which grandstands at its exit were removed in 2017 to add run-off.
Turn 13: New Holland (Turn 13) The first part of a very fast sixth-gear double right-hander onto the pit straight, named for the agricultural-machinery maker New Holland. It became faster and more important after F1 dropped the final chicane, though sources differ on whether the name covers Turn 13 alone or the 13 to 14 sweep.
Turn 14: Turn 14 The unnamed final right-hander that completes the fast double-apex sweep and crosses the line onto the pit straight.
