Over the past two years, the sport’s brain trust has made a genuine effort to investigate incorporating SUVs into NASCAR events as more than just support vehicles for VIPs. That initiative has been intertwined with the development of an electric platform for potential use in the O’Reilly Auto Parts series, which is the next step down from primo Cup action. The crossover body shapes have already been designed and tested in partnership with high-tech engineering giant ABB.

When pressed by traditionalist fans in an uproar over the potential encroachment of both SUVs and EVs into NASCAR’s hydrocarbon-rich contests, NASCAR officials have been measured in their comments. This isn’t the first time that the organization has ruffled feathers by considering a dramatic break with the past—witness the controversy during the ’90s when the Craftsman Truck series was launched to harness the popularity of pickups. Adding crossovers to the O’Reilly Auto Parts events is positioned as something similar that could give it a more distinct identity versus Cup racing.

“Long term … you’d have a truck, a CUV, and a Cup [series]. That’s three very different bodies that are relevant for our OEMs today,” NASCAR Executive Vice President John Probst told the media when asked about the development program. This was followed by a statement from Mike Forde, NASCAR’s managing director of racing communications: “If you look at the production car landscape, sedans aren’t what they used to be, and CUVs are the hot thing right now. So that’s just something that we need to be ready for in case there are no sedans in 10 years.”

Regardless of the timetable, it seems clear that crossovers are on the horizon for NASCAR, which got us thinking about what models would be the best choice for each of the sport’s current roster of automakers—and which fresh faces the decision to race crossovers on Sunday and sell SUVs on Monday might attract.

Here are our top picks for entries in what we’re dubbing the NASCAR Crossover Series, leaning toward EV models but with some gas-powered options, as well.
