#The six real shapes this gap takes

A named model or trim ladder is the clearest version: the 2026 Corvette has five real models under one badge, the 2027 Jeep Gladiator and the 2026 Jeep Compass each have a trim ladder where one specific trim drives outsized real demand, and the Cadillac CT5 splits into three real cars under one name.

A powertrain split is the single most common shape in the series: the Kia Sportage, the Honda CR-V, the Chevrolet Equinox and Blazer, the BMW i4, the Grand Wagoneer's REEV, the Kia Telluride's new Hybrid, and the Kia Seltos's trim-gated turbo engine all share this shape.

A body-style or wheelbase split now spans four real pairs: the Chevrolet Tahoe and Suburban, the Jeep Grand Wagoneer and Grand Wagoneer L, the Grand Cherokee and Grand Cherokee L, and the GMC Yukon and Yukon XL: the same underlying pattern, confirmed independently on three different manufacturers.

An engine-specific figure treated as lineup-wide shows up on the Ram 1500's towing and payload gap, the GMC Sierra 1500's own three-engine split, and the Chevy Silverado 2500HD/3500HD's gas-versus-Duramax split. Two newer shapes only became visible at scale: a shared trim-naming convention repeating across otherwise unrelated vehicles: BMW's X1/X3/X7, GMC's Canyon/Acadia/Terrain, and Buick's four-nameplate lineup: and real, sourced cross-model comparison demand, found on the Cadillac Optiq, the Chevrolet Traverse, the Jeep Wrangler, and now the all-electric Jeep Recon against the gas Wrangler.

#Why this keeps happening, and what closes it every time

The mechanical cause is the same across all 26 lines. A dealer's inventory platform, and often the manufacturer's own marketing, groups configurations under one nameplate for reasons that have nothing to do with content: filtering a search-results page, unifying an ad campaign, keeping a badge recognizable, or reusing a trim name brand-wide for consistency. None of those reasons make the underlying vehicles the same. A content page inherits the grouping anyway, without inheriting a reason to treat it as one answer.

The fix has been identical on every page in this series: name the specific configuration, model, trim, powertrain, body style or vehicle before stating a figure, and source that figure to the manufacturer's own already-published number for that exact configuration. Nothing here required new vehicle research on any of the 31 pages. Every fact traces back to a page the manufacturer or an independent aggregator like KBB already maintains: the content gap was never about missing data.
