Speedway Motorsports, led by CEO Marcus Smith, is joining the zMAX CARS Tour ownership group, the series announced.

The organization, which owns and operates 11 racing facilities, Performance Racing Network, U.S. Legends Car International and SMI Properties, joins Dale Earnhardt Jr., Kevin Harvick, Jeff Burton and Justin Marks as co-owners of the asphalt late model series.

"The CARS Tour has grown leaps and bounds the past few years and welcoming Marcus into the ownership group is just another step in our effort to bring the best Late Model racing in America to as many people as possible," said Marks. "Marcus' experience, perspective and business ecosystem will prove very valuable as the CARS Tour continues to establish itself as can't-miss short track racing."

"Since the creation of U.S. Legend Cars International in 1992, Speedway Motorsports has been committed to grassroots racing and developing the next generation of NASCAR drivers," said Smith. "This investment with the zMAX CARS Tour is a logical next step for us to help Legend Car drivers move to late models and then to NASCAR's national series, while continuing to maximize a fantastic marketing platform for our zMAX line of automotive additives."
