The series also visited Belgium, France, Hungary, Germany and the United Kingdom during the season, while Formula Renault 3.5 had two extra races on its own, in support of the Monaco Grand Prix in May, and also the 1000 km of Algarve in August.
Baguette remained in contention with Martínez despite not winning a race in the first half of the season, finishing in the top three four times.
However, Martínez's season hit the buffers after that, and Baguette moved into the championship lead after a double win at Le Mans.
After the Algarve round, six drivers were split by just fifteen points with Walker, Carlin Motorsport's Jaime Alguersuari, Martínez, Charles Pic of Tech 1 Racing (a race winner at Silverstone), Alguersuari's team-mate Oliver Turvey (winner of the Monaco Grand Prix-support round) and Ultimate Motorsport's Miguel Molina were all in the running for the honours.
Pic's second win of the season, gave him the advantage heading to Alcañiz, leading Walker by seven, Alguersuari by nine, and Fauzy and Turvey by seventeen.
One of Félix da Costa's endless teammates at Motopark, Marco Sørensen took his first win during the second Hungaroring race, but was latterly disqualified from the weekend a couple of weeks later due to a non-compliance on his car during the Super Pole session.
Félix da Costa then took his first Eurocup victory at Silverstone, to take a five-point lead at the halfway stage of the championship.
Félix da Costa and Kevin Magnussen both ran under appeal during the weekend, due to technical infringements.
Sadly for the Portuguese driver, Costa dominated the whole weekend: two pole positions, two fastest laps and two wins; moving into a decisive championship lead.
Félix da Costa completed the double in the second race, taking his championship tally to 128 points.
That placing was vital for the French driver, as he and Félix da Costa finished tied on points, with Vergne taking second due to an extra win on countback.
Quaife-Hobbs took fourth in the championship, after edging a final race battle with Vergne's team-mate Miquel Monrás.
A retirement for Hirschi in race one also meant that Verschuur's championship lead heading to Alcañiz was a comfortable fourteen points.
Verschuur took the title with a double win, and Hirschi took second after Enjalbert suffered a costly retirement from the final race of the season.
