Dover Speedway signs Autotrader and EchoPark Automotive as sponsors for July race

Autotrader, a Cox Automotive brand and America’s online leader for car buyers, and EchoPark Automotive, one of the nation’s top sellers of pre-owned vehicles, are partnering with Dover Motor Speedway on The Monster Mile’s signature event of 2025.

The Autotrader EchoPark Automotive 400 on Sunday, July 20 (2 p.m., TNT, Performance Racing Network) is the centerpiece of Dover Motor Speedway’s July 18-20 NASCAR tripleheader weekend and the 107th NASCAR Cup Series race at The Monster Mile.

Autotrader, founded in 1997 and a Cox Automotive™ brand, provides car buyers and sellers with the largest online market in the country and has revolutionized the third-party automotive purchase experience. Echo Park Automotive, a used-car dealership chain, has locations in more than 20 states. Its parent company, Sonic Automotive, was founded in 1997 by the late O. Bruton Smith, the founder of Speedway Motorsports.

The partnership with Dover Motor Speedway comes after Autotrader’s successful sponsorship of the NASCAR Cup Series race at Texas Motor Speedway every season since 2020. This collaboration allows Autotrader to expand its motorsports presence in the Northeast and mid-Atlantic regions.
