The change occurred as a result of gradual improvements to the quality of the cars in recent years and the signing of a new sponsor to the division.
The speedway announced that more modern muscle car body packages will be introduced for the 2011 season including Dodge Challenger, Chevrolet Camaro, and Ford Mustang.
In an effort to create an easy entry level and add additional entertainment value to the track, the speedway announced in the 2008 Rule package the introduction of a 4-cylinder "Chaos Car".
The car count held steady into the beginning of the 2010 season, which finished the year with 12 vehicles competing in the finale in which the championship was won by "Blue Thunder".
The series experienced the largest single-day growth of a division in speedway history with the introduction of the "Bone Stock" format, which updated the Chaos Car rules to fit an old-school 1990's Enduro-type race.
Super Modified racing did not return to Delaware Speedway until 2006 when the International Supermodified Association (ISMA) touring series made a stop.
Observers also cited strained relations between the track and CASCAR over the series' operations being controlled by its impending buyer NASCAR.
At the conclusion of the 2005 racing season, the speedway cancelled its NASCAR sanctioning at the same time as it dropped its CASCAR Super Series events.
Following the end of NASCAR sanctioning the speedway management set about a focus on building the profile of its weekly racing programs.
A new operations manager had been put in place before the new year, Paul Houghton, who had previously directed the track's Junior Racing League (JRL) program.
The 2009 season also featured numerous track renovations including repaving the majority of the front stretch, new corner lights, and electronic timing and scoring as well as a new ticketing system.
The 2010 Delaware Speedway season schedule was similar to that of 2009, with the addition of a special Summer Showdown featuring NASCAR drivers Kyle Busch, David Reutimann, and Jason Leffler.
The change in ownership was considered historically significant as it represented the first time the lease-holding Spivak family was to have a direct interest in the speedway business.
A new ownership group, The Delaware Group, consisting of Walt Spivak, Jon Aarts (John Aarts Group/J-AAR) and the United Racing Series (Ivor Jones, John Jones and Luke Ramsay) now oversees the track with Dave Graham managing operations under the role of General Manager.
Luke Ramsay has assumed the position of President of Delaware Speedway with Darryl Timmermans in the role of Competition Director.
The new ownership group significantly invested in the facility including racetrack surface upgrades that began at the conclusion of the 2021 race season.
