This question will resolve as Yes if there is an official announcement from NASCAR that a fourth manufacturer will race in the NASCAR Cup series before the 2030 season.
Fine Print
If NASCAR ceases to exist before the resolution date, or if one of the current manufacturers leaves the sport but the sport continues, this question will resolve as N/A.
Ever since Dodge left the NASCAR Cup Series after the 2012 season, only three manufacturers have remained in the series: Ford, Chevrolet and Toyota. Speculation has abounded for many years that a new manufacturer will join the series, or that Dodge will return.
@Space Waves Honda or even Dodge (making a comeback?) are often rumored. But with the cost of entry and how tight the current field is, any new manufacturer would need a solid long-term plan. 2030 feels realistic — if it happens, it’ll likely be announced a few years in advance.
