The NASCAR Whelen Euro Series, formerly known as the Racecar Euro Series, was formed in 2008 to bring the concept of American stock cars racing to continental Europe. NASCAR's official recognition came in January 2012, when the series' organizers, Team FJ, signed a long-term relationship with Whelen Engineering as the series title sponsor. 

The NASCAR euro season consists of seven rounds held on the most outstanding European tracks, totaling 28 races split evenly between the EuroNASCAR PRO and EuroNASCAR 2 (AM) championships. Over 400 HP V8 beasts give genuine racing excitement and exhilarating bumper-to-bumper fights with four races in two days. The NASCAR euro series draws drivers from all over the world who are eager to compete for the win and take the first step toward becoming a NASCAR star in the United States. The NASCAR European series is one of three NASCAR-sanctioned international series.

The NASCAR Whelen Euro Series is a motorsport series that combines the concept of NASCAR-style cars with European circuits. These Euro-NASCAR cars are specially built for European tracks and are inspired by American NASCAR cars. They are equipped with a powerful V8 engine producing 450 hp, a rear-wheel-drive system, and a four-speed manual gearbox. The cars weigh 1,225 kg and feature a new generation design called the "Next Level" package, which includes a redesigned aerodynamic package and composite body. The series has also introduced sequential gearboxes and has exclusive partnerships with tire and fuel suppliers. The cars are also used in the Race of Champions event.

 

A NASCAR Whelen Euro Series race week typically spans three days and consists of four races: two EuroNASCAR PRO races and two EuroNASCAR 2 races. The schedule begins with practice sessions on Friday, allowing drivers to familiarize themselves with the track and make necessary car adjustments. On Saturday, qualifying takes place, determining the starting positions for the first races of both EuroNASCAR PRO and EuroNASCAR 2. The day concludes with the actual races for both classes. Finally, on Sunday, the second races for EuroNASCAR PRO and EuroNASCAR 2 are held, bringing the race week to a close.

The NASCAR Whelen Euro Series features various championship categories to recognize and reward drivers' performances. In the EuroNASCAR PRO drivers championship, drivers of all skill levels, represented by gold, silver, and bronze categories, can participate. On the other hand, the Junior Trophy is exclusively for drivers who are 25 years old or younger. The Challenger Trophy is dedicated to amateur drivers, while the EuroNASCAR 2 drivers championship is restricted to silver and bronze drivers. The Legend Trophy celebrates drivers aged 40 and over, while the Rookie Cup is for debutants regardless of age or experience. The Lady Cup is a special category for female drivers. The teams' championship is based on points accumulated by cars in both divisions. The series' champions and exceptional drivers are honored at the annual NASCAR Home Tracks Champions Awards at the NASCAR Hall of Fame.
