Official trailers show quad / ATV-class vehicles away from the neon strip — dirt, scrub, and inland Leonida rather than Ocean Drive traffic. The silhouette is clear enough to list the type. It is not clear enough to invent a manufacturer badge.
Rockstar has not published off-road handling notes, a dirt-bike-versus-ATV catalog, or a “how many quads” number. Map-6 will not fill those blanks with GTA Online carry-over names.
The type matters for map literacy: when footage leaves causeways for trails and wetlands, the vehicle language changes. That is why this row exists beside convertibles and cruisers — contrast, not a garage checklist.
If a later Newswire or official site names a specific ATV, cite that URL here and upgrade the label. Until then, confidence stays trailer-visible.
