Nascar Affiliations

Modified Tour

The NASCAR Whelen Modified Tour (NWMT) (previously the NASCAR Winston Modified Tour and NASCAR Featherlite Modified Series from 1985 until 2005) is a stock car racing series owned and operated by NASCAR in the Modified Division. The Modified Division is NASCAR’s oldest division, and is the only open-wheeled division that NASCAR sanctions. NASCAR Whelen Modified Tour events are mainly held in the northeastern United States, but the 2007 and 2008 tours expanded to the Midwest with the addition of a race in Mansfield, Ohio. The tour races primarily on short oval paved tracks, but the NWMT also has made appearances at larger ovals and road courses.

Euro Series

The only official NASCAR racing series in Europe, the Whelen Euro Series travels the continent with the best NASCAR road course racing. It was founded in 2008 thanks to a long-term partnership with NASSCAR, Team FJ, and Whelen Engineering as the title sponsor. Featuring four races in two days, these 400+ HP V8 monsters provide pure racing action and thrilling bumper-to-bumper battles as well as a lot of family fun around the track.


Whelen Engineering and Motorsports go together as well as oil and engines. For over 25 years Whelen has supported NASCAR and its grass roots racing series. Recently Whelen has taken to the sky as well and gotten into Aviation Racing and Acrobatics. Paired up with NASCAR to have four sponsorships, Marsh Racing and Mike Goulian Aerobatics, you can find Whelen on most tracks or runways.

A lot of our success on and off of the track has been due to the fans and customers of racing and aero sports. Join us on social networks for the latest news and find out where we will be next!
