01 / Tables

GX dimensions and capacities by model year

Length, width and height are the maker’s overall figures (width without mirrors). The wheelbase is the distance between the axles, the turning circle the curb-to-curb diameter, and a pickup’s bed figures are measured inside the box. Capacities are the fuel tank the maker prints and the seats it fits. Every 2025–2026 GX has the 3.4-liter twin-turbo V6, Four-wheel drive and 10-speed automatic. Figures in US units; model years printed the same share one table, and a package that changes a figure gets its own row.
