The 2015 NASCAR Whelen Euro Series was the seventh Racecar Euro Series season, and the third under the NASCAR Whelen Euro Series branding.
The Elite 1 championship was won for the third time in four years by Ander Vilariño in the No. 2 TFT Racing Chevrolet Camaro.[1] He scored three victories during the season, and ultimately won the championship by 35 points ahead of CAAL Racing driver Alon Day, who also took three victories – coming at the final two meetings of the season, at Magione and Zolder – during his first season in the championship. Third place, 13 points further in arrears, was Vilariño's team-mate Romain Iannetta, who won a race at Brands Hatch. Three other drivers won races during the season; Nicolò Rocca was another three-time winner for CAAL Racing, but he finished down in ninth in the drivers' championship, while Eddie Cheever III and defending champion Anthony Kumpen won a race apiece at Valencia and Venray respectively. Rocca won the Race And Win Pole Award for scoring the highest number of pole positions with four; the other two poles went to Day.
The Elite 2 championship was won by Gianmarco Ercoli, who won four races driving his No. 9 Double T by MRT Nocentini Chevrolet Camaro.[2] Ercoli won the championship by 20 points ahead of Philipp Lietz, who won both races at Venray for GDL Racing. Third place in the championship – four points behind Lietz – went to Knauf Racing Team's Thomas Ferrando, who achieved three victories during 2015. The season's other race-winners finished fourth, fifth and sixth in the championship; Stienes Longin won at Tours Speedway for PK Carsport, Salvador Tineo Arroyo won at Magione for CAAL Racing and Dexwet Renauer Team's Florian Renauer was a race-winner at Brands Hatch.
