To celebrate the golden anniversary of iconic motor oil and lubricant brand Mobil 1, Stewart-Haas Racing driver Josh Berry will battle at Martinsville with an equally-gleaming gold race car. When the NASCAR Cup Series® hits Martinsville Speedway on Sunday, April 7, Berry’s No. 4 Ford Mustang will pay homage to the legendary history of the Mobil 1 brand and its industry-leading technology that has helped vehicles of all kinds - from the street, to the race track, and everything in between - perform at their best. Berry’s fans can now add the No. 4 Mobil 1 50th Anniversary Ford Mustang to their NASCAR® die-cast collections.
